SecureZIP Command Line Standard Edition on UNIX/Linux

On UNIX and Linux, SecureZIP Command Line Standard Edition adds the following features to the set provided by PKZIP Standard Edition:

  • Email and FTP integration: Options to create and transfer archives by email or FTP directly from the command line. See "Sending an Archive by SecureFTP, FTP and Email."
  • PKSFX: The ability to create self-extracting ZIP files for use in either the native command line or graphical Windows environment. See "Working with Self-Extracting (PKSFX) Archives."
  • Strong passphrase-based encryption: Strong encryption—the kind of encryption used by banks and the federal government—is much more secure than the weaker, traditional ZIP encryption provided by PKZIP. See "Encrypting Files with a Passphrase."
  • Strong encryption using a digital certificate instead of a passphrase: This kind of encryption is both more convenient and more secure than passphrase-based encryption, and it enables you to encrypt files just for the people you want to see them. See "Encrypting Files with a Recipient List."
  • Strong file name encryption: With this feature, you can encrypt even the names of files in an archive so that only the intended recipients of the archive can read them. See "Encrypting File Names."
  • Digital signatures: When you attach a digital signature, recipients of your files can be sure that the files are unchanged and really come from you. See "Attaching Digital Signatures."

PKZIP and SecureZIP Enterprise Editions

The Enterprise editions of SecureZIP and PKZIP command Line each add an additional module of functionality to the respective products.

PKZIP Enterprise Edition

PKZIP CLI Enterprise Edition includes the Enhanced Data Processing module. This module adds these features to PKZIP (all are included in SecureZIP):

SecureZIP Enterprise Edition

SecureZIP Enterprise Edition includes the Directory Integration module. This module enables SecureZIP to access digital certificates stored on directory servers anywhere in the enterprise. Being able to access certificates on directory servers makes it much more convenient to do strong certificate-based encryption, as you can encrypt for a set of recipients without needing to have the certificate for each recipient on your own machine. See "Accessing Recipients in an LDAP Directory."

SecureZIP Enterprise Edition also includes the Contingency Keys module. Contingency keys are digital certificate-based keys that an administrator can have automatically included in the recipient list whenever PKZIP does strong encryption. See "Contingency Keys" for more information.

SecureZIP Enterprise Edition provides additional functionality regarding OpenPGP keys and X.509 certificates. These include:

  • Ability to generate OpenPGP keys
  • Convert X.509 certificates to OpenPGP keys
  • Convert OpenPGP keys to X.509 certificates
  • Signing OpenPGP keys

If you are transitioning from the McAfee eBusiness Server (EBS), you can use SecureZIP Enterprise Edition in OpenPGP Mode to run many of your existing EBS scripts with minimal editing. The commands include decrypt, encrypt, and sign. These commands and options are described on this page.

Find more information about Enterprise Edition features, including installation and a command reference, in the Getting Started with PKWARE Key Maker guide.

This manual is not the only way to learn about PKZIP and SecureZIP. You can find additional information inside the program itself, and on the World Wide Web.

Using Help

PKZIP provides a help system for the PKZIP commands and options. The help system describes syntax and shows sample command lines.
Access the help system directly from the command line:

  • At the command prompt, type the following and press ENTER:

pkzipc -help

A screen with PKZIP version and usage information appears. You can get help for any PKZIP command or option from here.

  • To bypass the command/option menu and go directly to a help file for a command or option, type the help command followed by an equal sign (=) and the command or option for which you want information.

For example, to access online help for the add command, type the following at the command prompt and press ENTER:

pkzipc -help=add

The help information for the add command appears.

Getting Version Information

version

To list the version of PKZIP that you are using, use the version command:

pkzipc -version

This command line outputs two lines like the following after the usual header information:

Program File Version (pkzipc): 12.50.1087
Product Version: 12.50.0005

The first line lists major, minor, and step version numbers of the program:

Program File Version (pkzipc): <major>.<minor>.<step>

The second line lists the major and minor version numbers and the build number of the product.

Product Version: <major>.<minor>.<build>

Major and minor version numbers of the program are always the same as those for the product.

In addition to producing this display output, the version command returns a version number as a value to the shell. The version number returns as a positive integer value less than 256. This value is only returned to the shell and is not displayed in normal output. It can be used to verify PKZIP version numbers in a .BAT file or shell script.

Sub-options of the version command (described in the following table) determine which version number is returned. The major version number is returned by default.

Sub-Option

PKZIP Returns

For example

major

The major release number. For example, if the version number is 12.10.1054, the value returned is 12. This is the default return.

pkzipc -version

pkzipc -version=major

minor

The minor number of the release. For example, if the version number is 12.10.1054, the value returned is 10.

pkzipc -version=minor

step

The step or patch value (minus 1000 if ≥ 1000). For example, if the program version is 12.10.1054, the value returned is 54.

pkzipc -version=step

product

The build number of the product. For example, if the product version is 12.10.0003, the value returned is 3.

pkzipc -version=product

Entering License Keys

Note: To use SecureZIP Partner, as a participant in PKWARE PartnerLink, you do not need to enter a license key. You can ignore this section and related sections on getting license information and sharing a license, later in this chapter.

You must enter your license key to activate the product and for any add-on modules after you complete the installation.

You must run PKZIP as root to use the enterlicensekey command. If you try to run the command as an ordinary user instead of as the super user, you get an error.

Running the enterlicensekey command creates a license.ini file (if it does not exist already) in the PKZIP installation directory where the executable is located. The license file must be in this directory for PKZIP to find it. The default location of this directory is:

  • /opt/pkware/pkzip/bin/ on Solaris and HP-UX
  • /usr/pkware/pkzip/bin/ on AIX and Linux.

Make the directory and its files readable for all users and writable for none.

You can use the enterlicensekey command to enter license keys on Windows as well. You may want to do this if you need to enter the license key for an add-on module that you purchase sometime after you purchased the base product.

To enter a license key:

  1. Become the super user to run the program as root.
  2. At the command prompt, type the following and press ENTER:
    pkzipc -enterlicensekey 

    PKZIP prompts you for a product license key.
  3. Enter a product license key and press ENTER.

Repeat these steps for each license key you have. For example, if you have a license key for an add-on module, repeat the steps above to enter the license key for that module after you enter the license key for the base product.

Getting License Information

To display the PKZIP license information on your screen, type pkzipc -license at the command prompt and press ENTER

Using Wildcards with PKZIP on UNIX

If your shell is set up to automatically expand wildcards, you should put file specifications that use wildcards—for example, — in quotation marks—like this: —on the command line to prevent the shell from expanding them.

Allowing the shell to expand wildcard file specifications into an explicit list of files can cause the PKZIP recurse and directories options not to work properly. Placing a wildcard pattern in quotes instructs the shell to pass the pattern as an argument to PKZIP, which then expands it.

PKZIP can interpret and expand the following wildcard patterns:

Pattern

Example

*

*

*<pattern>*

<pattern>*

<pattern><pattern>*

<pattern>

Running the Program as Root

Setting the set-uid bit on the pkzipc binary causes PKZIP to run as root. It also causes PKZIP to run any program that it may launch—such as the ftp client (ftp option)—as root.

Use considerable caution in setting the set-uid bit to run PKZIP as root. It is very easy for a program running as root to overwrite system files, and setting the setuid bit on any program raises security concerns.

Configure PKZIP to run this way only in keeping with organizational security policies and on the instructions of a system administrator.

Information for PartnerLink™ Sponsors and Partners

PKWARE PartnerLink enables a sponsor organization that has SecureZIP to distribute to partner organizations the SecureZIP Partner application. That is, an organization that licenses SecureZIP can exchange strongly encrypted archives with selected Partner organizations, offering both sponsor and partner organizations secure business-to-business communication. SecureZIP Partner is a special version of SecureZIP. It provides most of the commands and options of SecureZIP but works only with archives created by (or for) a sponsor. Archives created using SecureZIP Partner are automatically strongly encrypted for sponsor recipients.

This section applies only to participants in the PKWARE PartnerLink program, including users of SecureZIP Partner. Other readers may skip this section.

Note: SecureZIP Partner was called SecureZIP Reader/SecureLink prior to release 8.5 of SecureZIP Server.

To use SecureZIP Partner, you do not need to enter a license key. Use of the software is controlled by the Sponsor Distribution Packages you install. Users of SecureZIP Partner can ignore the section "Entering License Keys" and related sections on getting license information and sharing a license.

A sponsor organization uses SecureZIP as usual to work with archives for, or from, a partner. There is just one special requirement when creating an archive for a partner: you must sign the central directory of the archive using a certificate included in the Sponsor Distribution Package (SDP). Otherwise a partner cannot extract the archive.

To sign an archive, use the certificate option. (See "Attaching Digital Signatures.") You may optionally sign files in addition to signing the archive itself. Use the sign option to specify what to sign: the central directory, the archive's files, or both.

For example, the following command line adds files to archive . The command line signs using the John Q. Public certificate and attaches the signature to the central directory only, not to the archive's files.

pkzipc -add -certificate="John Q. Public" -sign=cd test.zip *.*

Contact PKWARE for information about participating in the PartnerLink program or assembling a Sponsor Distribution Package for partners.

If You Are a Partner

A PartnerLink partner uses the SecureZIP Partner application to work with archives. The SecureZIP users manual you are now reading also serves as a user guide for SecureZIP Partner.

See the PartnerLink Partner Setup Guide: Windows/UNIX/Linux for information on installing SecureZIP Partner and on setting up as a partner to work with sponsor archives.

About SecureZIP Partner

SecureZIP Partner does basically two kinds of operations:

  • Extracts files from sponsor archives: SecureZIP Partner uses SecureZIP commands and options to extract files from a ZIP archive received from a sponsor. These commands and options include those to decrypt and decompress files and to authenticate digital signatures. SecureZIP Partner can only extract archives digitally signed by a PartnerLink sponsor.
  • Creates archives for sponsors: SecureZIP Partner uses SecureZIP commands and options to add files to a ZIP archive, including commands and options to compress, encrypt, and digitally sign files.

SecureZIP Partner can create and update archives only for a designated sponsor. Archives are automatically encrypted for all sponsor recipients whose certificates are included in the sponsor's SDP. Only those sponsor recipients can decrypt and read the files in an archive created by SecureZIP Partner. SecureZIP Partner does not use passphrase-based encryption.

Note: Because SecureZIP Partner automatically encrypts for sponsor recipients—and only for sponsor recipients—when adding files to an archive, partners cannot decrypt archives that they use SecureZIP Partner to create. So partners must be careful not to delete files they want to keep after placing them in an archive. A copy of a file in an archive will be inaccessible to the creator of the archive.

To Run SecureZIP Partner

The command to run SecureZIP Partner is pkzipr; the command to run SecureZIP is pkzipc. So, for example, where the manual says to use a command like the following to extract all files from archive myfiles.zip:

pkzipc -extract myfiles.zip

you would instead use a command line like one of those below to do the same thing with SecureZIP Partner:

pkzipr -extract myfiles.zip
pkzipr -extract -sponsor="Example Corp" myfiles.zip

SecureZIP Partner only operates on archives from, or for, a sponsor. A special sponsor option is provided just for SecureZIP Partner to designate a sponsor.

The sponsor option is only required when creating or updating an archive with the add command. The option can be explicitly included on the command line, or you can configure SecureZIP to designate a sponsor by default (see "Changing Defaults for Commands and Options - UNIX").

You do not need the sponsor option when extracting an archive with the extract command. If the option is not used when extracting, the signature on the archive is checked against all sponsors defined on the system.

Use the sponsor option when extracting if you want to ensure that only an archive from the specified sponsor is extracted. For example, you may have a script to process archives from a particular sponsor. Use the sponsor option with command lines in the script to ensure that the script does not inadvertently process an archive from some other sponsor.

You can use the sponsor option multiple times on the same command line when extracting but only once per command line when adding files to an archive.

The sponsor option accepts either a sponsor's common name or sponsor ID to identify a sponsor. To find out this information about a sponsor, use the PKSponsor list command or the SecureZIP Partner listSponsors command, to list sponsors. (PKSponsor is a tool included with SecureZIP Partner for setting up as a partner. See the PartnerLink Partner Setup Guide: Windows/UNIX/Linux.)

For example, the following command line adds files to a ZIP archive for sponsor Example Corp. It references Example Corp by common name:

pkzipr -add myfiles.zip -sponsor="Example Corp" *.doc

The similar example below uses the sponsor ID to reference a sponsor:

pkzipr -add myfiles.zip -sponsor=15 *.doc

If you have received an archive called , and you are uncertain which of your sponsors it came from, use the sponsor option twice to extract the archive's files from either sponsor:

pkzipr -extract -sponsor="Example Corp" -sponsor=20 myfiles.zip

SecureZIP Partner provides a listSponsors command to list sponsors, like the PKSponsor list command.

The following command line returns a list of sponsors on the system:

pkzipr -listsponsors

Output from listSponsors looks like this:

----- Sponsor #1 ----- Sponsor: PKWARE, Inc.
Sponsor ID: 0
Type: Read/Write
Description: <Sponsor 1's comment, if any>
--------------------------------------- Sponsor #2 ----- Sponsor: ABC Corp
Sponsor ID: 1
Type: Read/Write
 Description:
------------------------
2 sponsor(s) installed

The table below explains the fields.

Red Hat Enterprise Linux 8 is shipped with the default desktop environment GNOME 3.

GNOME 3 represents a presentation layer that provides a graphical user interface as well as the focused working environment, which enables you to access all your work from one place.

1.2. GNOME environments, back ends, and display protocols

GNOME 3 provides two user environments:

  • GNOME Standard
  • GNOME Classic

Both environments can use two different protocols as their graphical back ends:

  • The X11 protocol, which uses X.Org as the display server.
  • The Wayland protocol, which uses GNOME Shell as the Wayland compositor and display server.

    This solution of display server is further referred as GNOME Shell on Wayland.

The default combination in RHEL 8 is GNOME Standard environment using GNOME Shell on Wayland as the display server. However, due to certain Wayland limitations, you might want to switch the graphics protocol stack to X11. You may also want to switch from GNOME Standard to GNOME Classic.

1.9. Sharing media between applications

Red Hat Enterprise Linux 8 includes the PipeWire media server, which ensures access to multimedia devices and media sharing between applications.

When running a remote desktop session on GNOME Shell on Wayland, PipeWire and the VNC server is used. The functionality of remote desktop session is provided by the and packages.

On X.Org, just VNC is needed to run a remote desktop session. This functionality on X.Org is provided by the package.

PipeWire is used also with teleconference tools such as BlueJeans when running on GNOME Shell on Wayland. In such case, the is activated automatically when you start sharing your screen within the teleconference tool.

To check the status of the , run:

~]$ systemctl --user status pipewire

You can switch between several user interfaces in GNOME. Additionally, GNOME can run on several different graphics back ends.

2.1. GNOME environments, back ends, and display protocols

GNOME 3 provides two user environments:

  • GNOME Standard
  • GNOME Classic

Both environments can use two different protocols as their graphical back ends:

  • The X11 protocol, which uses X.Org as the display server.
  • The Wayland protocol, which uses GNOME Shell as the Wayland compositor and display server.

    This solution of display server is further referred as GNOME Shell on Wayland.

The default combination in RHEL 8 is GNOME Standard environment using GNOME Shell on Wayland as the display server. However, due to certain Wayland limitations, you might want to switch the graphics protocol stack to X11. You may also want to switch from GNOME Standard to GNOME Classic.

Additional resources

GNOME Standard user interface includes these major components:

Top bar
The horizontal bar at the top of the screen provides access to some of the basic functions of GNOME Standard, such as the Activities Overview, clock and calendar, system status icons, and the system menu.
System menu

The system menu is located in the top right corner, and enables you:

  • Updating settings
  • Controlling the sound bar
  • Finding information about your Wi-Fi connection
  • Switching user
  • Logging out
  • Turning off the computer
Activities Overview

The Activities Overview features windows and applications views that let the user run applications and windows and switch between them.

The search entry at the top allows for searching various items available on the desktop, including applications, documents, files, and configuration tools.

The vertical bar on the left side contains a list of favorite and running applications. You can add or remove applications from the default list of favorites according to your needs.

The workspace list displayed on the right side allows the user to switch between multiple workspaces, or move applications and windows from one workspace to another.

Message tray
The message tray provides access to pending notifications. The message tray shows when the user presses Super+M.

The GNOME 3 Standard Desktop

gnome standard new

GNOME Classic represents a mode for users who prefer a more traditional desktop experience that is similar to GNOME 2 environment used with Red Hat Enterprise Linux 6. It is based on GNOME 3 technologies, and at the same time it includes multiple features similar to GNOME 2.

GNOME Classic user interface consists of these major components:

Applications and Places

The Applications menu is displayed at the top left of the screen. It gives the user access to applications organized into categories. If you enable window overview, you can also open the Activities Overview from that menu.

The Places menu is displayed next to the Applications menu on the top bar. It gives the user quick access to important folders, for example Downloads or Pictures.

Taskbar

The taskbar is displayed at the bottom of the screen, and features:

  • A window list
  • A notification icon displayed next to the window list
  • A short identifier for the current workspace and total number of available workspaces displayed next to the notification icon
Four available workspaces
In GNOME Classic, the number of workspaces available to the user is by default set to 4.
Minimize and maximize buttons
Window titlebars in GNOME Classic feature the minimize and maximize buttons that let the user quickly minimize the windows to the window list, or maximize them to take up all of the space on the desktop.
A traditional Super+Tab window switcher
In GNOME Classic, windows in the Super+Tab window switcher are not grouped by application.
System menu

The system menu is located in the top right corner, and enables the following actions:

  • Updating settings
  • Controlling the sound bar
  • Finding information about your Wi-Fi connection
  • Switching user
  • Logging out
  • Turning off the computer

The GNOME 3 Classic desktop with the Rhythmbox application and the Favorites submenu of the Applications menu

gnome classic new

In GNOME Classic, the overview of windows that are open is not available by default. You can see the list of all open windows in the taskbar at the bottom of the screen. However, you can enable the windows overview similar to what is by default available in GNOME Standard by changing the default settings of the GNOME Classic environment as described in Section 2.4, “Enabling window overview in GNOME Classic”.

2.4. Enabling window overview in GNOME Classic

In GNOME Classic, the overview of open windows is not available by default. This procedure enables the window overview for all users on the system.

Enabling the window overview by this procedure is not a permanent change. Each update of the package overwrites the configuration file to the default settings, which disable the window overview.

To keep the window overview enabled, apply the procedure after each update of .

Procedure

  1. Open the file as the user.
  2. Find the following line in the file:

    "hasOverview": false
  3. Change the line to the following:

    "hasOverview": true
  4. Save changes, and close the file.
  5. Restart the user session.

Verification steps

  1. In your GNOME Classic session, open multiple windows.
  2. Press the Super key to open the window overview.
  3. In the overview, check that:

    • The Dash (the vertical panel on the left side of the screen) is displayed.
    • The bottom panel is not displayed.
    • The workspace switcher is displayed on the right side of the screen.

      Window overview with "hasOverview": true

      has overview true

    With the default settings (), the overview has the following features:

    • The Dash is not displayed.
    • The bottom panel is displayed. It includes the Window picker button in its left part and the workspace switcher in its right part.

      Window overview with "hasOverview": false

      has overview false

2.5. Graphics back ends in RHEL 8

In RHEL 8, you can choose between two protocols to build a graphical user interface:

X11
The X11 protocol uses X.Org as the display server. Displaying graphics based on this protocol works the same way as in RHEL 7, where this was the only option.
Wayland
The Wayland protocol on RHEL 8 uses GNOME Shell as its compositor and display server, which is further referred as GNOME Shell on Wayland. Displaying graphics based on the Wayland protocol has some differences and limitation compared to X11.

New installations of RHEL 8 automatically select GNOME Shell on Wayland. However, you can switch to X.Org, or select the required combination of GNOME environment and display server as described in Section 2.8, “Selecting GNOME environment and display protocol”.

Note that there are also a few environments where X.Org is preferred over GNOME Shell on Wayland, such as:

  • Cirrus graphics used in a VM environment
  • Matrox graphics
  • Aspeed graphics
  • QXL graphics used in a VM environment
  • Nvidia graphics when used with the proprietary driver

The Nvidia graphics by default use , which is an open source driver. is supported on Wayland, hence you can use Nvidia graphics with on GNOME Shell on Wayland without any limitations. However, using Nvidia graphics with proprietary Nvidia binary drivers is not supported on GNOME Shell on Wayland. In this case, you need to switch to X.Org as described in Section 2.8, “Selecting GNOME environment and display protocol”.

Additional resources

  • You can find the current list of environments for which Wayland is not available in the file.
  • For additional information on the Wayland project, see Wayland documentation.

2.6. Key differences between the Wayland and X11 protocol

X11 applications

Client applications need to be ported to the Wayland protocol or use a graphical toolkit that has a Wayland backend, such as GTK, to be able to work natively with the compositor and display server based on Wayland.

Legacy X11 applications that cannot be ported to Wayland automatically use Xwayland as a proxy between the X11 legacy clients and the Wayland compositor. Xwayland functions both as an X11 server and a Wayland client. The role of Xwayland is to translate the X11 protocol into the Wayland protocol and reversely, so that X11 legacy applications can work with the display server based on Wayland.

On GNOME Shell on Wayland, Xwayland is started automatically at startup, which ensures that most X11 legacy applications work as expected when using GNOME Shell on Wayland. However, the X11 and Wayland protocols are different, and hence some clients relying on X11-specific features may behave differently under Xwayland. For such specific clients, you can switch to the X.Org display server as described in Section 2.8, “Selecting GNOME environment and display protocol”.

libinput

Red Hat Enterprise Linux 8 uses a new unified input stack, , which manages all common device types, such as mice, touchpads, touchscreens, tablets, trackballs and pointing sticks. This unified stack is used both by the X.Org and by the GNOME Shell on Wayland compositor.

GNOME Shell on Wayland uses directly for all devices, and no switchable driver support is available. Under X.Org, is implemented as the X.Org driver, and driver support is outlined below.

Mice, touchscreens, trackballs, pointing sticks
Red Hat Enterprise Linux 8 uses the X.Org driver for these devices. The driver, which was used in Red Hat Enterprise Linux 7, is available as fallback where required.
Touchpads
Red Hat Enterprise Linux 8 uses the X.Org driver for touchpads. The driver, which was used for touchpads in Red Hat Enterprise Linux 7, is no longer available.
Graphics tablets
Red Hat Enterprise Linux 8 continues using the X.Org driver, which was used for tablet devices in Red Hat Enterprise Linux 7. However, the X.Org driver is available where required.
Other input devices
Red Hat Enterprise Linux 7 used the X.Org driver for other input devices that are not included in the above categories. Red Hat Enterprise Linux 8 uses the X.Org driver by default but can fall back to the X.Org driver if a device is incompatible with .

Gestures

GNOME Shell on Wayland supports new touchpad and touchscreen gestures. These gestures include:

  • Switching workspaces by dragging up or down with four fingers.
  • Opening the Activities overview by bringing three fingers closer together.

2.7. Current Wayland limitations

Nvidia drivers

Proprietary Nvidia binary drivers are not supported with GNOME Shell on Wayland. To avoid any complications while using the Nvidia GPU, GNOME Shell automatically falls back to X.Org, which means that the login screen does not provide any option based on the Wayland protocol.

The driver is still supported and is the default driver for Nvidia graphics.

Remote desktop

With GNOME Shell on Wayland, VNC support is provided by the package. Remote access using VNC via currently requires an already logged in session, and only the primary monitor is accessible. Screen sharing with GNOME Shell on Wayland is possible using the PipeWire media server. For more details on the PipeWire media server, see PipeWire project.

For more advanced VNC usage, you need to switch to X.org, where traditional VNC tools are available. For more information, see Section 2.8, “Selecting GNOME environment and display protocol” .

X Display Manager

The X Display Manager Control Protocol (XDMCP) is not supported with GNOME Shell on Wayland.

Hence, it is not possible to use the X display manager to start a session on the X.Org display server from the same or another computer.

Additional limitations

The following additional limitations related to the Wayland protocol should be noted:

  • X.Org screen manipulation utilities are not available.
  • The utility is not supported because Wayland handles layout, rotations, and resolutions differently.
  • GNOME Shell cannot be restarted using the Alt+F2r shortcut.
  • Due to stability issues, using X.org instead of Wayland is recommended in virtual environments. The graphics based on the Wayland protocol are not available for virtual machines that use the driver.
  • Wayland does not support the custom or niche input devices that cannot be handled by the driver.

Additional resources

  • You can find the current list of environments for which Wayland-based graphics are unavailable in the file.

2.8. Selecting GNOME environment and display protocol

The default desktop environment for Red Hat Enterprise Linux 8 is GNOME Standard with GNOME Shell on Wayland as the display server. However, due to certain limitations of Wayland, you might want to switch the graphics protocol stack. You might also want to switch from GNOME Standard to GNOME Classic.

Procedure

  1. From the login screen (GDM), click the cogwheel next to the Sign In button.

    You cannot access this option from the lock screen. The login screen appears when you first start Red Hat Enterprise Linux 8 or when you log out of your current session.

    gnome environments new

  2. From the drop-down menu that appears, select the option that you prefer.

    Note that in the menu that appears on the login screen, the X.Org display server is marked as X11 display server.

The change of GNOME environment and graphics protocol stack resulting from the above procedure is persistent across user logouts, and also when powering off or rebooting the computer.

Additional resources

You can connect to the desktop on a RHEL server from a remote client.

5.1. Remote desktop access options

RHEL provides several options for remotely connecting to the desktop. Each option fits a different use case:

Single-user access using GNOME tools

This method enables remote access on the client and the server using graphical GNOME applications. It configures a Virtual Network Computing (VNC) session so that only a single user can connect to the desktop on the server at a given time.

Depending on the session type, this method uses different components to implement screen sharing:

  • In an X11 session, it uses the component.
  • In a Wayland session, it uses the component.

    This method always uses display number 0. As a consequence, the VNC session always connects to the user who is logged into the server system.

    The VNC client application must support connections. For example, you can use the Remote Desktop Viewer () application on Linux systems. Before you can connect from Microsoft Windows clients, such as RealVNC, you must disable the VNC encryption on the server.

Multi-user access using command-line tools

This method configures a VNC session so that multiple remote clients can connect to the server in parallel. You must first enable the VNC access on the client and the server using command-line tools.

Any VNC client application can connect to a server configured using this method.

Accessing a single application using X11 forwarding over SSH

This method executes an SSH command on the client that launches an individual graphical on the server. The application window opens on the client.

This method is useful when you do not require a full remote desktop session.

5.2. Remotely accessing the desktop as a single user

You can remotely connect to the desktop on a RHEL server using graphical GNOME applications. Only a single user can connect to the desktop on the server at a given time.

Introduction

Minimizing vulnerabilities in your Secure Shell (SSH) protocol is key to ensuring the security of your Linux environment.

In this article, we cover the most common Linux SSH security measures you can take to make your servers more secure. By changing the default SSH port, using key pairs, and following the other recommended best practices, you can significantly improve the overall security of your system.

Five tips and best practices on how to improve SSH security

What is SSH?

The Secure Shell (SSH) protocol enables cryptographically protected remote system administration and file transfers over insecure networks. Using multiple encryption methods, SSH secures the connection between a client and a server safeguarding the users’ commands, authentication, and output against unauthorized access and attacks.

The SSH protocol is now widely used in data centers and by almost every major enterprise running on any of the UNIX variants.

When it comes to security measures, it is essential to combine them, apply them in layers, and not pick just one and rely on only that solution.

To learn more about SSH connections, visit our article about how SSH works.

1. Change the Default SSH Port

Using a non-standard port for SSH connection helps avoid automated attacks on your server. It also helps reduce the chances of it appearing on a hacker’s radar and makes it a less obvious target.

Note: The majority of hackers who are looking for OpenSSH servers will aim at the default SSH port 22.

In that case, the scripts they are using will look for IP addresses only on port 22. If your server falls into that group, every such automated attack will make an impact on your log files. Consequently, the load on your server may increase substantially since many SSH server exploits are running around the clock knocking on every server’s door.

It is important to note that changing the default SSH port does not improve the security of your server. However, it does help in keeping away automated attacks.

How to Change the Port Number

Before you begin, you need to decide which port you will use instead of the default port 22. Before you make a decision, you should consider a few things:

ssh-port-number-tips

To change the port on your Linux server, follow these steps:

  1. Connect to the server via SSH as you usually would.
  2. Switch to the root user using the su command, which will prompt you to enter the server password.
  3. Use a text editor of your choice to edit the sshd configuration file located in the directory. If you have never used a text editor within the terminal, it is recommended to use Nano. Otherwise, use vi or vim since they are the most commonly used editors today. We advise you to back up the original file before you make any changes.
  4. Run this command to edit the configuration file:
  1. In the output of the sshd_config file locate the line which says “.”
editing the sshd config file
  1. Change the port number to the value of your choice. Make sure there is no “” at the beginning of the line.
  2. Exit the editor and confirm that you want to save the changes.
  3. For the changes to take effect, restart the sshd service with this command:
  1. Verify that the SSH is listening on the port you specified by connecting to it.

Note that now you will need to specify the port when connecting since your client will always use the default SSH port unless told otherwise.

Benefits

While the procedure for changing the default SSH port does not increase the level of security itself, it takes you off the radar of the most common scans. One easy way to test this is to let your server run for a few days with sshd listening on the default port and then change it to a non-standard one. Compare the number of failed logins on your server, and you will see it decrease substantially.

By using a non-standard port for SSH:

  • You avoid being seen by random scans.
  • It is more difficult to find your server. Most of the attacks will scan the default port or some variants of it, but will move on once the connection is refused.
  • SSH daemon can take a break since it will not get connection requests from scripted attacks. Server load is reduced, and the log file stays clean saving you time in reviewing it.
  • You do not receive as many alerts for failed logins. If you are using a non-standard port and someone still tries to access your server, it probably means that your server is specifically being targeted and that the alarm is not coming from a scripted attack.
  • You are less exposed to being hacked due to the bugs in sshd or weak private keys.
  • Most hackers will be repelled if they see that you are not using the default port. It will be a sign that the server is properly protected and that there are probably other security measures taken as well, making your server an undesirable target.

Drawbacks

There are some precautions to keep in mind before you decide to change the default port for SSH. The disadvantages of running a non-standard port can mean that:

  • Anybody who should be able to connect to your server will need to be informed of the change and will have to start using the new port.
  • If you are using outsourced monitoring for your server, you also need to make them aware of the change. Otherwise, they may treat this as a potential threat which may lead to server downtime.
  • The firewall rules related to the SSH service have to be inspected and modified according to the changes you make.

Some of these disadvantages probably will not apply to your use case but should be taken into consideration. The benefits of changing the port outweigh the drawbacks and prove to be a good additional layer of security for your server.

2. Enhance Linux SSH Security Using Key Pairs

One of the most secure methods to authenticate clients to servers is by using SSH key pairs. Strong passwords may be sufficient to keep your server safe, but persistent brute force attacks can still crack them. This is why you need additional SSH hardening with key pairs.

SSH keys are resilient to such attacks and are virtually impossible to decrypt. An SSH key pair consists of two long series of characters, a private key which is kept secret, and a public key which can be safely shared. Their purpose is similar to passwords, and they allow you to automatically establish an SSH session without the need to type in a password.

How to Generate a Key Pair

To set up SSH keys, you will need to generate a key pair on the client computer which will be used to connect to the server. To do so:

  1. Start the terminal and run the SSH keygen utility, available with the standard OpenSSH tool.
  1. You will get the message “Generating public/private RSA key pair.” If you want to save the key to the default location, press when prompted. The key will be saved in the home user’s directory, in the directory. To change the location, just type in the new path. The recommendation is to stick with the default location, so you do not have to make any changes to your SSH client. The private, or the identification key, will be saved as and the corresponding public key as .
  2. Optionally, you can insert a passphrase. If you do not wish to use one, press to continue. The passphrase provides an additional layer of security by encrypting the private key on the local machine. To crack the passphrase, a hacker will need to have access to the system first, since the private key is not exposed on the network. Even then, it will take time to succeed, allowing you to change the used key before the hacker gains access to other servers. The downside is that you will have to enter it every time you try to connect using that key.

The process of generating a key pair is complete.

The final screen will look similar to this:

Note: You can make the authentication/authorization even more secure by creating larger 4096-bit keys instead of the default 2048 bits. To do so, append to the command. It will look like this:

ssh-keygen -t rsa -b 4096

Copying a Public Key

To use the key pair you’ve created on your machine for SSH authentication, you need to place the public key on the desired server. The simplest way to do so is to use the tool available with OpenSSH:

The procedure is easy:

  1. Type in .
  2. If you are connecting for the first time to this host, you will get an authenticity message. Type to continue.
  3. Input your password when asked, and the tool will copy the contents of  key to the file under the home directory on the server.

Note: No characters will be visible while you are typing the password due to security reasons.

  1. You will get a message:
copying public key ssh

Your public key has been placed on the remote server, and now you can log into it without entering the account’s password.

  1. To test if the authentication with the keys is working, connect to your server with . If successful, you will be automatically logged in. In case you had previously set up a passphrase, you will need to enter it first before you are granted access to the server.

How Keys Work

Essentially, a public key is not a key. It behaves like a padlock that you can put on an SSH account on another machine. When you run the ‘ssh-keygen’ utility, you generate both the padlock and the key that opens it, and respectively.

You can make as many copies of the padlock as necessary, distribute them to any server you like, and only you will have the right key to unlock them all. This is why it is important to keep the private key safe because it unlocks all the copies of the padlocks you’ve handed out.

It does not matter where you put your public key as long as the master key does not get compromised. Since nobody else possesses the private key, this method for authorization and authentication is probably the safest out there and highly recommended.

3. Disable Server SSH Root Login

Linux server distributions have outside root access enabled by default. This can be a severe security threat since hackers can try to crack the password with brute force attacks. It is recommended to disable root login and use a regular account and a  command to switch to the root user.

Before you disable the root login, make sure that you have added an account that can gain root access. To do so, follow the steps below:

  1. Use SSH to log into the server as root.

2. Use a text editor to open the main configuration file. This time, we will use the vi editor.

3. Find the line that says “ and change to . You may need to scroll down a few lines to find it.

4. It is important to add the user account you will use to log in. Just add another line with the username in question:

5. Save the changes you made and then exit the text editor.

6. Restart the SSH service but do not close the root session yet. For Ubuntu and Debian use and for Fedora/CentOS use the  command.

Open a new terminal window and verify that you can now log in as the user you added. Once you confirm it works, exit the active root session.

4. Disable Password-Based Logins on Your Server

If you are using SSH keys for SSH authentication, you can disable the server password authentication altogether. This is another way to keep your server safe from brute-force attacks and attempts to crack your password. Before you proceed, double-check if SSH key-based authentication is working for the root account on the server or for an account with the sudo access.

When you are ready, complete these steps:

  1. Use SSH keys to log into the server as root or with sudo privileges.

2. Use a text editor to open the sshd_config file. We will use vi:

3. Look for the line that says and change to . Make sure to uncomment the line if the is present.

4. Save the changes you’ve made and then exit the text editor.

5. Restart the SSH service to apply the changes. For Ubuntu/Debian use and for Fedora/CentOS use the command.

Congratulations, you have successfully disabled the option to log in through SSH using account passwords. SSH Daemon will simply ignore any authentication requests which do not include private/public key pairs.

5. Restrict SSH Access Using iptables

Iptables is a Linux utility used for configuring firewall rules and monitoring/filtering incoming and outgoing traffic to your server. It is included by default with most Linux distributions.

With iptables, you can define rules that limit or permit traffic for different kinds of services by IP address, port or network protocol and thus substantially improve the security of your server. In our case, we will set firewall rules to restrict the incoming SSH traffic for everyone but one IP address or subnet.

This way, blocking port 22 will not only stop unauthorized access to your servers but can also stop or prevent DDoS attacks.

While taking this step, you should make sure you do not lock yourself out by completely blocking SSH traffic.You will need to use only a few commands to allow a specific IP address or subnet for incoming SSH connections.

Note: Commands are case sensitive.

This rule will whitelist the IP address that you’ve typed in. Please replace the example IP in the command with your IP. You can also use a subnet, for example, 10.10.10.0/24.

You need to save the rules, so you do not lose them after reboot:

If you want to view the list of all iptables rules, you can use the command. To include more details such as packet, byte and target information, append to the command above. Add to all of it and the output will be displayed in numeric format.

In case you want to reset all rules and start clean, use the flush command . This will clear the iptables configuration which is useful if you are unsure if everything is set up as you want it.

Iptables parameters and Options Definitions

Here are some explanations for iptables parameters, options, and values used in the examples above, as well as a few not mentioned before.

ValueDescription
ACCEPTAllows the packets to pass through
DROPBlocks the packets
RETURNTells to skip the current chain and resume at the next rule in the previous (calling) chain

>ParameterDescription
-ccounters allows setting the packet and byte counters of a specific rule
-ddestination – can be an address, name of a host or address, etc.
-ffragment – applies the rule to the second and the fragments that follow it
-ggoto chain – states that the action will continue in a user-specified chain

-Ccheck – checks for a rule that matches the criteria in the selected chain
-Ddelete – deletes only one rule from the selected chain
-Fflush – deletes all defined iptables rules
-Iinsert – insert a rule into the selected chain
-Llist – displays the rules of the selected chain

Conclusion, SSH Security, and Hardening Best Practices

Whether you are building a new server or a virtual machine, it is good practice to implement multiple security layers within your environment. Businesses are usually keen on setting up their infrastructure as soon as possible, but necessary security measures have to be applied right from the start.

If you employ the Linux SSH security methods listed above, you should be able to avoid common security threats in the cloud.

Make it hard for the hackers to penetrate your server(s) and restrict any damage. Make sure you implement as many of these best practices as possible before making your server available on the network.

Don’t forget to check out our regularly-updated list of Best Cybersecurity Blogs you should be following to keep yourself on top of all the latest trends.

Which File Transfer Method Is Best for Your Home Network?

When you create your own file server or network-attached storage, you might be surprised how much thought you need to give to moving your files around.

To the human eye, each approach looks the same (as in invisible), but on the technical level, your computers are talking in very different ways. Which approach you take will depend on what operating systems and types of devices you intend to connect.

1. FTP

FTP stands for File Transfer Protocol. It's a standard method for moving files around between a client and a server. Your laptop, for example, is the client. Your home server is, well, the server.

FTP is versatile in that your operating system really doesn't matter. The protocol has been around since before any of them had graphical user interfaces. Your router may even come with a USB port and support transferring data to an external hard drive via FTP (which is an easy way to create a home server, albeit nowhere near as robust as setting up a dedicated machine for the job).

You can protect your data by requiring a username and password, but by default FTP will transfer your credentials unencrypted. This may be okay on your home network, but you will want something more secure when operating on a larger network or transmitting files over the internet.

That doesn't mean you need to abandon FTP. You can try FTPS, a variation that encrypts your connection.

Here's how to send and receive files from a Mac via FTP.

2. SMB

SMB stands for Server Message Block. Though it began as an IBM project, it became a means for computers running Microsoft Windows to communicate over a local network. When you create a folder using Windows Explorer and expand access to other users, you're doing so via SMB.

SMB is not limited to Windows users. You can also access these files from macOS, Linux, and other Unix-like operating systems. Apple calls its implementation SMBX, while on Linux the implementation is known as Samba. In either case, your laptop can serve as either the server or the client.

SMB is great for spreading files between machines on a local network in a cross-platform way. Users don't need any technical knowledge to start sharing folders and downloading files, aside from awareness of the network section in a file manager's sidebar.

3. AFP

AFP, or Apple Filing Protocol, is Apple's proprietary system for connecting different macOS computers. If you have a household filled with Apple products, or you run a company that uses Apple hardware, then this may be the most relevant file transfer protocol for you.

While AFP is specific to Apple devices, you can buy home media systems that support the protocol. You can also set up your own FreeNAS or OpenMediaVault box with an old PC and use AFP to share files with your iMacs, MacBooks, and iPads.

On the other hand, if you aren't working exclusively with Apple hardware, there's little reason to concern yourself with AFP. This protocol is rather specialized. Other options offer better cross-platform compatibility or communication between servers.

4. NFS

The Network File System, known as NFS, is a protocol in use on Unix and Unix-like computers (such as Linux). Its strength lies in the ability for many machines to access the same server regularly. NFS can offer faster speeds on computers that support the protocol.

One drawback of NFS is that, even if you use a Linux-based desktop, setup isn't obvious. Instructions will generally point you toward the command line, with you needing to tell your computer to mount network shares like it mounts physical hardware. As the name suggests, you're treating a shared folder on a network as though it were part of your file system.

Again, setting up NFS is not hard if you're comfortable with the command line, but the process is not something intuitive you can discover and set up from your desktop's file manager.

5. SSH/SFTP

SSH stands for Secure Shell. It is a method of connecting to and managing a remote machine. If you want to run commands on a server, whether it lives in your basement or on a server farm thousands of miles away, you can turn to SSH to get the job done.

On its own, SSH is not a file transfer protocol. That's where SFTP comes in, otherwise known as the SSH File Transfer Protocol or Secure File Transfer Protocol. This is a way of transferring files over an encrypted connection. Despite the similarity in name, SFTP does not refer to using FTP over SSH, which is a complicated affair.

SFTP is a different method of transferring data using the same technology as SSH.

SFTP is not necessary for a home server unless you're concerned that someone has access to your Wi-Fi network and is snooping on your traffic. SFTP is a better option for transferring files from or to locations outside of your home. But that doesn't mean you must use SSH when you're moving files around remotely.

If you have an active VPN connection encrypting your web traffic, then you can use FTP or mount NFS shares knowing your data has some protection. Using SFTP in conjunction with a VPN is somewhat redundant.

6. DLNA

DLNA is short for Digital Living Network Alliance. It's a certification standard rather than a file transfer protocol, but it's still an acronym you may need to know when setting up a home media server. If you intend to stream files to a Smart TV or video game console, you will need a server with DLNA support.

To stream content via DLNA, you don't open your file manager to share or access files. You're not accessing files via a method known as DLNA.

Instead, you need dedicated software. Plex is one of the most popular examples, with Emby being an open source alternative. Such programs take your raw files and transmit them in a format that DLNA-compatible devices understand.

You can stream music and video from a desktop, laptop, or a dedicated NAS. What matters is that you're running the necessary software on both the device that's sending and the device that's receiving.

The Best Way to Transfer Files on a Home Network

Every bit of software or code on your computer ultimately exists somewhere as a file, so it's no surprise that there are many ways to move files around. But this need not be complicated. Depending on your use-case, some protocols are easy to recommend.

  • Use Windows and want to share files with family members? SMB
  • Have an Apple household instead? AFP
  • Want to share files between two Linux-based desktops? SMB
  • Want an ongoing connection between a Linux-based desktop and server? NFS
  • Want something that really doesn't care what OS you prefer? FTP
  • Need security when you're away from home? SFTP
  • Stream music and videos to a TV? DLNA

Don't want to bother with a network? You can always stick to using flash drives instead. Or if you're working with large media files, you may want to go with a portable hard drive.

The Enterprise editions of SecureZIP and PKZIP command Line each add an additional module of functionality to the respective products.

PKZIP Enterprise Edition

PKZIP CLI Enterprise Edition includes the Enhanced Data Processing module. This module adds these features to PKZIP (all are included in SecureZIP):

SecureZIP Enterprise Edition

SecureZIP Enterprise Edition includes the Directory Integration module. This module enables SecureZIP to access digital certificates stored on directory servers anywhere in the enterprise. Being able to access certificates on directory servers makes it much more convenient to do strong certificate-based encryption, as you can encrypt for a set of recipients without needing to have the certificate for each recipient on your own machine. See "Accessing Recipients in an LDAP Directory."

SecureZIP Enterprise Edition also includes the Contingency Keys module. Contingency keys are digital certificate-based keys that an administrator can have automatically included in the recipient list whenever PKZIP does strong encryption. See "Contingency Keys" for more information.

SecureZIP Enterprise Edition provides additional functionality regarding OpenPGP keys and X.509 certificates. These include:

  • Ability to generate OpenPGP keys
  • Convert X.509 certificates to OpenPGP keys
  • Convert OpenPGP keys to X.509 certificates
  • Signing OpenPGP keys

If you are transitioning from the McAfee eBusiness Server (EBS), you can use SecureZIP Enterprise Edition in OpenPGP Mode to run many of your existing EBS scripts with minimal editing. The commands include decrypt, encrypt, and sign. These commands and options are described on this page.

Find more information about Enterprise Edition features, including installation and a command reference, in the Getting Started with PKWARE Key Maker guide.

This manual is not the only way to learn about PKZIP and SecureZIP. You can find additional information inside the program itself, and on the World Wide Web.

Using Help

PKZIP provides a help system for the PKZIP commands and options. The help system describes syntax and shows sample command lines.
Access the help system directly from the command line:

  • At the command prompt, type the following and press ENTER:

pkzipc -help

A screen with PKZIP version and usage information appears. You can get help for any PKZIP command or option from here.

  • To bypass the command/option menu and go directly to a help file for a command or option, type the help command followed by an equal sign (=) and the command or option for which you want information.

For example, to access online help for the add command, type the following at the command prompt and press ENTER:

pkzipc -help=add

The help information for the add command appears.

Getting Version Information

version

To list the version of PKZIP that you are using, use the version command:

pkzipc -version

This command line outputs two lines like the following after the usual header information:

Program File Version (pkzipc): 12.50.1087
Product Version: 12.50.0005

The first line lists major, minor, and step version numbers of the program:

Program File Version (pkzipc): <major>.<minor>.<step>

The second line lists the major and minor version numbers and the build number of the product.

Product Version: <major>.<minor>.<build>

Major and minor version numbers of the program are always the same as those for the product.

In addition to producing this display output, the version command returns a version number as a value to the shell. The version number returns as a positive integer value less than 256. This value is only returned to the shell and is not displayed in normal output. It can be used to verify PKZIP version numbers in a .BAT file or shell script.

Sub-options of the version command (described in the following table) determine which version number is returned. The major version number is returned by default.

Sub-Option

PKZIP Returns

For example

major

The major release number. For example, if the version number is 12.10.1054, the value returned is 12. This is the default return.

pkzipc -version

pkzipc -version=major

minor

The minor number of the release. For example, if the version number is 12.10.1054, the value returned is 10.

pkzipc -version=minor

step

The step or patch value (minus 1000 if ≥ 1000). For example, if the program version is 12.10.1054, the value returned is 54.

pkzipc -version=step

product

The build number of the product. For example, if the product version is 12.10.0003, the value returned is 3.

pkzipc -version=product

Entering License Keys

Note: To use SecureZIP Partner, as a participant in PKWARE PartnerLink, you do not need to enter a license key. You can ignore this section and related sections on getting license information and sharing a license, later in this chapter.

You must enter your license key to activate the product and for any add-on modules after you complete the installation.

You must run PKZIP as root to use the enterlicensekey command. If you try to run the command as an ordinary user instead of as the super user, you get an error.

Running the enterlicensekey command creates a license.ini file (if it does not exist already) in the PKZIP installation directory where the executable is located. The license file must be in this directory for PKZIP to find it. The default location of this directory is:

  • /opt/pkware/pkzip/bin/ on Solaris and HP-UX
  • /usr/pkware/pkzip/bin/ on AIX and Linux.

Make the directory and its files readable for all users and writable for none.

You can use the enterlicensekey command to enter license keys on Windows as well. You may want to do this if you need to enter the license key for an add-on module that you purchase sometime after you purchased the base product.

To enter a license key:

  1. Become the super user to run the program as root.
  2. At the command prompt, type the following and press ENTER:
    pkzipc -enterlicensekey 

    PKZIP prompts you for a product license key.
  3. Enter a product license key and press ENTER.

Repeat these steps for each license key you have. For example, if you have a license key for an add-on module, repeat the steps above to enter the license key for that module after you enter the license key for the base product.

Getting License Information

To display the PKZIP license information on your screen, type pkzipc -license at the command prompt and press ENTER

Using Wildcards with PKZIP on UNIX

If your shell is set up to automatically expand wildcards, you should put file specifications that use wildcards—for example, — in quotation marks—like this: —on the command line to prevent the shell from expanding them.

Allowing the shell to expand wildcard file specifications into an explicit list of files can cause the PKZIP recurse and directories options not to work properly. Placing a wildcard pattern in quotes instructs the shell to pass the pattern as an argument to PKZIP, which then expands it.

PKZIP can interpret and expand the following wildcard patterns:

Pattern

Example

*

*

*<pattern>*

<pattern>*

<pattern><pattern>*

<pattern>

Running the Program as Root

Setting the set-uid bit on the pkzipc binary causes PKZIP to run as root. It also causes PKZIP to run any program that it may launch—such as the ftp client (ftp option)—as root.

Use considerable caution in setting the set-uid bit to run PKZIP as root. It is very easy for a program running as root to overwrite system files, and setting the setuid bit on any program raises security concerns.

Configure PKZIP to run this way only in keeping with organizational security policies and on the instructions of a system administrator.

Information for PartnerLink™ Sponsors and Partners

PKWARE PartnerLink enables a sponsor organization that has SecureZIP to distribute to partner organizations the SecureZIP Partner application. That is, an organization that licenses SecureZIP can exchange strongly encrypted archives with selected Partner organizations, offering both sponsor and partner organizations secure business-to-business communication. SecureZIP Partner is a special version of SecureZIP. It provides most of the commands and options of SecureZIP but works only with archives created by (or for) a sponsor. Archives created using SecureZIP Partner are automatically strongly encrypted for sponsor recipients.

This section applies only to participants in the PKWARE PartnerLink program, including users of SecureZIP Partner. Other readers may skip this section.

Note: SecureZIP Partner was called SecureZIP Reader/SecureLink prior to release 8.5 of SecureZIP Server.

To use SecureZIP Partner, you do not need to enter a license key. Use of the software is controlled by the Sponsor Distribution Packages you install. Users of SecureZIP Partner can ignore the section "Entering License Keys" and related sections on getting license information and sharing a license.

A sponsor organization uses SecureZIP as usual to work with archives for, or from, a partner. There is just one special requirement when creating an archive for a partner: you must sign the central directory of the archive using a certificate included in the Sponsor Distribution Package (SDP). Otherwise a partner cannot extract the archive.

To sign an archive, use the certificate option. (See "Attaching Digital Signatures.") You may optionally sign files in addition to signing the archive itself. Use the sign option to specify what to sign: the central directory, the archive's files, or both.

For example, the following command line adds files to archive. The command line signs using the John Q. Public certificate and attaches the signature to the central directory only, not to the archive's files.

pkzipc -add -certificate="John Q. Public" -sign=cd test.zip *.*

Contact PKWARE for information about participating in the PartnerLink program or assembling a Sponsor Distribution Package for partners.

If You Are a Partner

A PartnerLink partner uses the SecureZIP Partner application to work with archives. The SecureZIP users manual you are now reading also serves as a user guide for Free YouTube Download Partner.

See the PartnerLink Partner Setup Guide: Windows/UNIX/Linux for information on installing SecureZIP Partner and on setting up as a partner to work with sponsor archives.

About SecureZIP Partner

SecureZIP Partner does basically two kinds of operations:

  • Extracts files from sponsor archives: SecureZIP Partner uses SecureZIP commands and options to extract files from a ZIP archive received from a sponsor. These commands and options include those to decrypt and decompress files and to authenticate digital signatures. SecureZIP Partner can only extract archives digitally signed by a PartnerLink sponsor.
  • Creates archives for sponsors: SecureZIP Partner uses SecureZIP commands and options to add files to a ZIP archive, including commands and options to compress, encrypt, and digitally sign files.

SecureZIP Partner can create and update archives only for a designated sponsor. Archives are automatically encrypted for all sponsor recipients whose certificates are included in the sponsor's SDP. Only those sponsor recipients can decrypt and read the files in an archive created by SecureZIP Partner. SecureZIP Partner does not use passphrase-based encryption.

Note: Because SecureZIP Partner automatically encrypts for sponsor recipients—and only for sponsor recipients—when adding files to an archive, partners cannot decrypt archives that they use SecureZIP Partner to create. So partners must be careful not to delete files they want to keep after placing them in an archive. A copy of a file in an archive will be inaccessible to the creator of the archive.

To Run SecureZIP Partner

The command to run SecureZIP Partner is pkzipr; the command to run SecureZIP is pkzipc. So, for example, where the manual says to use a command like the following to extract all files from archive myfiles.zip:

pkzipc -extract myfiles.zip

you would instead use a command line like one of those below to do the same thing with SecureZIP Partner:

pkzipr -extract myfiles.zip
pkzipr -extract -sponsor="Example Corp" myfiles.zip

SecureZIP Partner only operates on archives from, or for, a sponsor. A special sponsor option is provided just for SecureZIP Partner to designate a sponsor.

The sponsor option is only required when creating or updating an archive with the add command. The option can be explicitly included on the command line, or you can configure SecureZIP to designate a sponsor by default (see "Changing Defaults for Commands and Options - UNIX").

You do not need the sponsor option when extracting download morphvox pro full crack archive with the extract command. If the option is not used when extracting, the signature on the archive is checked against all sponsors defined on the system.

Use the sponsor option when extracting if you want to ensure that only an archive from the specified sponsor is extracted. For example, you may have a script to process archives from a particular sponsor. Use the sponsor option with command lines in the script to ensure that the script does not inadvertently process an archive from some other sponsor.

You can use the sponsor option multiple times on the same command line when extracting but only once per command line when adding files to an archive.

The sponsor option accepts either a sponsor's common name or sponsor ID to identify a sponsor. To find out this information about a sponsor, use the PKSponsor list command or the SecureZIP Partner listSponsors command, to list sponsors. (PKSponsor is a tool included with SecureZIP Partner for setting up as a partner. See the PartnerLink Partner Setup Guide: Windows/UNIX/Linux.)

For example, the following command line adds files to a ZIP archive for sponsor Example Corp. It references Example Corp by common name:

pkzipr -add myfiles.zip -sponsor="Example Corp" *.doc

The similar example below uses the sponsor ID to reference a sponsor:

pkzipr -add myfiles.zip -sponsor=15 *.doc

If you have received an archive calledand you are uncertain which of your sponsors it came from, use the sponsor option twice to extract the archive's files from either sponsor:

pkzipr -extract -sponsor="Example Corp" -sponsor=20 myfiles.zip

SecureZIP Partner provides a listSponsors command to list sponsors, like the PKSponsor list command.

The following command line returns a list of sponsors on the system:

pkzipr -listsponsors

Output from listSponsors looks like this:

----- Sponsor #1 ----- Sponsor: PKWARE, Inc.
Sponsor ID: 0
Type: Read/Write
Description: <Sponsor 1's comment, if any>
--------------------------------------- Sponsor #2 ----- Sponsor: ABC Corp
Sponsor ID: 1
Type: Read/Write
 Description:
------------------------
2 sponsor(s) installed

The table below explains the fields.

Red Hat Enterprise Linux 8 is shipped with the default desktop environment GNOME 3.

GNOME 3 represents a presentation layer that provides a graphical user interface as well as the focused working environment, which enables you to access all your work from one place.

1.2. GNOME environments, back ends, and display protocols

GNOME 3 provides two user environments:

  • GNOME Standard
  • GNOME Classic

Both environments can use two different protocols as their graphical back ends:

  • The X11 protocol, which uses X.Org as the display server.
  • The Wayland protocol, which uses GNOME Shell as the Wayland compositor and display server.

    This solution of display server is further referred as GNOME Shell on Wayland.

The default combination in RHEL 8 is GNOME Standard environment using GNOME Shell on Wayland as the display server. However, due to certain Wayland limitations, you might want to switch the graphics protocol stack to X11. You may also want to switch from GNOME Standard to GNOME Classic.

You can switch between several user interfaces in GNOME. Additionally, GNOME can run on several different graphics back ends.

2.1. GNOME environments, back ends, and display protocols

GNOME 3 provides two user environments:

  • GNOME Standard
  • GNOME Classic

Both environments can use two different protocols as their graphical back ends:

  • The X11 protocol, which uses X.Org as the display server.
  • The Wayland protocol, which uses GNOME Shell as the Wayland compositor and display server.

    This solution of display server is further referred as GNOME Shell on Wayland.

The default combination in RHEL 8 is GNOME Standard environment using GNOME Shell on Wayland as the display server. However, due to certain Wayland limitations, you might want to switch the graphics protocol stack to X11. You may also want to switch from GNOME Standard to GNOME Classic.

Additional resources

GNOME Standard user interface includes these major components:

Top bar
The horizontal bar at the top of the screen provides access to some of the basic functions of GNOME Standard, such as the Activities Overview, clock and calendar, system status icons, and the system menu.

The GNOME 3 Standard Desktop

gnome standard new

GNOME Classic represents a mode for users who prefer a more traditional desktop experience that is similar to GNOME 2 environment used with Red Hat Enterprise Linux 6. It is based on GNOME 3 technologies, and at the same time it includes multiple features similar to GNOME 2.

GNOME Classic user interface consists of these major components:

Applications and Places

The Applications menu is displayed at the top left of the screen. It gives the user access to applications organized into categories. If you enable window overview, you can also open the Activities Overview from that menu.

The Places menu is displayed next to the linux ftp client - Crack Key For U menu on the top bar. It gives the user quick access to important folders, for example Downloads or Pictures.

Taskbar

The taskbar is displayed at the bottom of the screen, and features:

  • A window list
  • A notification icon displayed next to the window list
  • A short identifier for the current workspace and total number of available workspaces displayed next to the notification icon
Four available workspaces
In GNOME Classic, the number of workspaces available to the user is by default set to 4.
Minimize and maximize buttons
Window titlebars in GNOME Classic feature the minimize and maximize buttons that let the user quickly minimize the windows to the window list, or maximize them to take up all of the space on the desktop.
A traditional Super+Tab window switcher
In GNOME Classic, windows in the Super+Tab window switcher are not grouped by application.
System menu

The system menu is located in the top right corner, and enables the following actions:

  • Updating settings
  • Controlling the sound bar
  • Finding information about your Wi-Fi connection
  • Switching user
  • Logging out
  • Turning off the computer

The GNOME 3 Classic desktop with the Rhythmbox application and the Favorites submenu of the Applications menu

gnome classic new

In GNOME Classic, the overview of windows that are open is not available by default. You can see the list of all open windows in the taskbar at the bottom of the screen. However, you can enable the windows overview similar to what is by default available in GNOME Standard by changing the default settings of the GNOME Classic environment as described in Section 2.4, “Enabling window overview in GNOME Classic”.

2.4. Enabling window overview in GNOME Classic

In GNOME Classic, the overview of open windows is not available by default. This procedure enables the window overview for all users on the system.

Enabling the window overview by this procedure is not a permanent change. Each update of the package overwrites the configuration file to the default settings, which disable the window overview.

To keep the window overview enabled, apply the procedure after each update of.

Procedure

  1. Open the file as the user.
  2. Find the following line in the file:

    "hasOverview": false
  3. Change the line to the following:

    "hasOverview": true
  4. Save changes, and close the file.
  5. Restart the user session.

Verification steps

  1. In your GNOME Classic session, open multiple windows.
  2. Press the Super key to open the window overview.
  3. In the overview, check that:

    • The Dash (the vertical panel on the left side of the screen) is displayed.
    • The bottom panel is not displayed.
    • The workspace switcher is displayed on the right side of the screen.

      Window overview with "hasOverview": true

      has overview true

    With the default settings (), the overview has the following features:

    • The Dash is not displayed.
    • The bottom panel is displayed. It includes the Window picker button in its left part and the workspace switcher in its right part.

      Window overview with "hasOverview": false

      has overview false

2.5. Graphics back ends in RHEL 8

In RHEL 8, you can choose between two protocols to build a graphical user interface:

X11
The X11 protocol uses X.Org as the display server. Displaying graphics based on this protocol works the same way as in RHEL 7, where this was the only option.
Wayland
The Wayland protocol on RHEL 8 uses GNOME Shell as its compositor and display server, which is further referred as GNOME Shell on Wayland. Displaying graphics based on the Wayland protocol has some differences and limitation compared to X11.

New installations of RHEL 8 automatically select GNOME Shell on Wayland. However, you can switch to X.Org, or select the required combination of GNOME environment and display server as described in Section 2.8, “Selecting GNOME environment and display protocol”.

Note that there are also a few environments where X.Org is preferred over GNOME Shell on Wayland, such as:

  • Cirrus graphics used in a VM environment
  • Matrox graphics
  • Aspeed graphics
  • QXL graphics used in a VM environment
  • Nvidia graphics when used with the proprietary driver

The Nvidia graphics by default usewhich is an open source driver. is supported on Wayland, hence you can use Nvidia graphics with on GNOME Shell on Wayland without any limitations. However, using Nvidia graphics with proprietary Nvidia binary drivers is not supported on GNOME Shell on Wayland. In this case, you need to switch to X.Org as described in Section 2.8, “Selecting GNOME environment and display protocol”.

Additional resources

  • You can find the current list of environments for which Wayland is not available in the file.
  • For additional information on the Wayland project, see Wayland documentation.

2.6. Key differences between the Wayland and X11 protocol

X11 applications

Client applications need to be ported to the Wayland protocol or use a graphical toolkit that has a Wayland backend, such as GTK, to be able to work natively with the compositor and display server based on Wayland.

Legacy X11 applications that cannot be ported to Wayland automatically use Xwayland as a proxy between the X11 legacy clients and the Wayland compositor. Xwayland functions both as an X11 server and a Wayland client. The role of Xwayland is to translate the X11 protocol into the Wayland protocol and reversely, so that X11 legacy applications can work with the display server based on Wayland.

On GNOME Shell on Wayland, Xwayland is started automatically at startup, which ensures that most X11 legacy applications work as expected when using GNOME Shell on Wayland. However, the X11 and Wayland protocols are different, and hence some clients relying on X11-specific features may behave differently under Xwayland. For such specific clients, you can switch to the X.Org display server as described in Section 2.8, “Selecting GNOME environment and display protocol”.

libinput

Red Hat Enterprise Linux 8 uses a new unified input stack,which manages all common device types, such as mice, touchpads, touchscreens, tablets, trackballs and pointing sticks. This unified stack is used both by the X.Org and by the GNOME Shell on Wayland compositor.

GNOME Shell on Wayland uses directly for all devices, and no switchable driver support is available. Under X.Org, is implemented as the X.Org driver, and driver support is outlined below.

Mice, touchscreens, trackballs, pointing sticks
Red Hat Enterprise Linux 8 uses the X.Org driver for these devices. The driver, which was used in Red Hat Enterprise Linux 7, is available as fallback where required.
Touchpads
Red Hat Enterprise Linux 8 uses the X.Org driver for touchpads. The driver, which was used for touchpads in Red Hat Enterprise Linux 7, is no longer available.
Graphics tablets
Red Hat Enterprise Linux 8 continues using the X.Org driver, which was used for tablet devices in Red Hat Enterprise Linux 7. However, the X.Org driver is available where required.
Other input devices
Red Hat Enterprise Linux 7 used the X.Org driver for other input devices that are not included in the above categories. Red Hat Enterprise Linux 8 uses the X.Org driver by default but can fall back to the X.Org driver if a device is incompatible with.

Gestures

GNOME Shell on Wayland supports new touchpad and touchscreen gestures. These gestures include:

  • Switching workspaces by dragging up or down with four fingers.
  • Opening the Activities overview by bringing three fingers closer together.

2.7. Current Wayland limitations

Nvidia drivers

Proprietary Nvidia binary drivers are not supported with GNOME Shell on Wayland. To avoid any complications while using the Nvidia GPU, GNOME Shell automatically falls back to X.Org, which means that the login screen does not provide any option based on the Wayland protocol.

The driver is still supported and is the default driver for Nvidia graphics.

Remote desktop

With GNOME Shell on Wayland, VNC support is provided by the package. Remote access using VNC via currently requires an already logged in session, and only the primary monitor is accessible. Screen sharing with GNOME Shell on Wayland is possible using the PipeWire media server. For more details on the PipeWire media server, see PipeWire project.

For more advanced VNC usage, you need to switch to X.org, where traditional VNC tools are available. For more information, see Section 2.8, “Selecting GNOME environment and display protocol”.

X Display Manager

The X Display Manager Control Protocol (XDMCP) is not supported with GNOME Shell on Wayland.

Hence, it is not possible to use the X display manager to start a session on the X.Org display server from the same or another computer.

Additional limitations

The following additional limitations related to the Wayland protocol should be noted:

  • X.Org screen manipulation utilities are not available.
  • The utility is not supported because Wayland handles layout, rotations, and resolutions differently.
  • GNOME Shell cannot be restarted using the Alt+F2r shortcut.
  • Due to stability issues, using X.org instead of Wayland is recommended in virtual environments. The graphics based on the Wayland protocol are not available for virtual machines that use the driver.
  • Wayland does not support the custom or niche input devices that cannot be handled by the driver.

Additional resources

  • You can find the current list of environments for which Autodesk 3ds max 2019 graphics are unavailable in the file.

2.8. Selecting GNOME environment and display protocol

The default desktop environment for Red Hat Enterprise Linux 8 is GNOME Standard with GNOME Shell on Wayland as the display server. However, due to certain limitations of Wayland, you might want to switch the graphics protocol stack. You might also want to switch from GNOME Standard to GNOME Classic.

Procedure

  1. From the login screen (GDM), click the cogwheel next to the Sign In button.

    You cannot access this option from the lock screen. The login screen appears when you first start Red Hat Enterprise Linux 8 or when you log out of your current session.

    gnome environments new

  2. From the drop-down menu that appears, select the option that you prefer.

    Note that in the menu that appears on the login screen, the X.Org display server is marked as X11 display server.

The change of GNOME environment and graphics protocol stack resulting from the above procedure is persistent across user logouts, and also when powering off or rebooting the computer.

Additional resources

You can connect to the desktop on a RHEL server from a remote client.

5.1. Remote desktop access options

RHEL provides several options for remotely connecting to the desktop. Each option fits a different use case:

Single-user access using GNOME tools

This method enables remote access on the client and the server using graphical GNOME applications. It configures a Virtual Network Computing (VNC) session so that only a single user can connect to the desktop on the server at a given time.

Depending on the session type, this method uses different components to implement screen sharing:

  • In an X11 session, it uses the component.
  • In a Wayland session, it uses the component.

    This method always uses display number 0. As a consequence, the VNC session always connects to the user who is logged into the server system.

    The VNC client application must support connections. For example, you can use the Remote Desktop Viewer () application on Linux systems. Before you can connect from Microsoft Windows clients, such as RealVNC, you must disable the VNC encryption on the server.

Multi-user access using command-line tools

This method configures a VNC session so that multiple remote clients can connect to the server in parallel. You must first enable the VNC access on the client and the server using command-line tools.

Any VNC client application can connect to a server configured using this method.

Accessing a single application using X11 forwarding over SSH

This method executes an SSH command on the client that launches an individual graphical on the server. The application window opens on the client.

This method is useful when you do not require a full remote desktop session.

5.2. Remotely accessing the desktop as a single user

You can remotely connect to the desktop on a RHEL server using graphical GNOME applications. Only a single user can connect to the desktop on the server at a given time.

5.2.1. Enabling desktop sharing on the server using GNOME

This procedure configures a RHEL server to enable a remote desktop connection from a single client.

Procedure

  1. Configure a firewall rule to enable VNC access to the server:

    # firewall-cmd --permanent --add-service=vnc-server
  2. Reload firewall rules:

    # firewall-cmd --reload
  3. Open Settings in GNOME.
  4. Navigate to the Sharing menu:

    screen sharing 0

  5. Click Screen Sharing.

    The screen sharing configuration opens:

    screen sharing 1 off

  6. Click the switch button in the window header to enable screen sharing:

    screen sharing 2 on highlight

  7. Select the Allow connections to control the screen check box.
  8. Under Access Options, select the Require a password option.

Popular tools for brute-force attacks [updated for 2020]

The brute force attack is still one of the most popular password-cracking methods. Nevertheless, it is not just for password cracking. Brute force attacks can also be used to discover hidden pages and content in a web application. This attack is basically “a hit and try” until you succeed. This attack sometimes takes longer, but its success rate is higher. 

In this article, I will try to explain brute force attacks and popular tools used in different scenarios for performing brute force attacks to get desired results.

What is a brute force attack?

A brute force attack when an attacker uses a set of predefined values to attack a target and analyze the response until he succeeds. Success depends on the set of predefined values. If it is larger, it will take more time, but there is a better probability of success. 

The most common and easiest to understand example of the brute force attack is the dictionary attack to crack passwords. In this, the attacker uses a password dictionary that contains millions of words that can be used as a password. The attacker tries these passwords one by one for authentication. If this dictionary contains the correct password, the attacker will succeed.

In a traditional brute force attack, the attacker just tries the combination of letters and numbers to generate a password sequentially. However, this traditional technique will take longer when the password is long enough. These attacks can take several minutes to several hours or several years, depending on the system used and length of password.

To prevent password cracking from brute force attacks, one should always use long and complex passwords. This makes it hard for attackers to guess the password, and brute force attacks will take too much time. Account lockout is another way to prevent the attacker from performing brute force attacks on web applications. However, for offline software, things are not as easy to secure.

Similarly, for discovering hidden pages, the attacker tries to guess the name of the page, sends requests and sees the response. If the page does not exist, it will show a 404 response; on a success, the response will be 200. In this way, it can find hidden pages on any website.

Brute force is also used to crack the hash and guess a password from a given hash. In this, the hash is generated from random passwords and then this hash is matched with a target hash until the attacker finds the correct one. Therefore, the higher the type of encryption (64-bit, 128-bit or 256-bit encryption) used to encrypt the password, the longer it can take to break.

Reverse brute force attack

A reverse brute force attack is another term that is associated with password cracking. It takes a reverse approach in password cracking. In this, the attacker tries one password against multiple usernames. Imagine if you know a password but do not have any idea of the usernames. In this case, you can try the same password and guess the different usernames until you find the working combination.

Now, you know that a brute-forcing attack is mainly used for password cracking. You can use it in any software, any website or any protocol linux ftp client - Crack Key For U does not block requests after a few invalid trials. In this post, I am going to add a few brute force password-cracking tools for different protocols.

Popular tools for brute force attacks

Aircrack-ng

I am sure you already know about the Aircrack-ng tool. This is a popular brute force wifi password cracking tool available for free. I also mentioned this tool in our older post on most popular password-cracking tools. This tool comes with WEP/WPA/WPA2-PSK cracker and analysis tools to perform attacks on Wi-Fi 802.11. Aircrack-ng can be used for any NIC which supports raw monitoring mode.

It basically performs dictionary attacks against a wireless network to guess the password. As you already know, the success of the attack depends on the dictionary of passwords. The better and more effective the password dictionary is, the more likely it is that it will crack the password.

It is available for Windows and Linux platforms. It has also been ported to run on iOS and Android platforms. You can try it on given platforms to see how this tool aimersoft video converter ultimate registration code be used for brute force wifi password cracking.

John the Ripper

John the Ripper is another awesome tool that does not need any introduction. It has been a favorite choice for performing brute force attacks for a long time. This free password-cracking software was initially developed for Unix systems. Later, developers released it for various other platforms. Now, it supports fifteen different platforms including Unix, Windows, DOS, BeOS and OpenVMS. 

You can use this either to identify weak passwords or to crack passwords for breaking authentication.

This tool is very popular and combines various password-cracking features. It can automatically detect the type of hashing used in a password. Therefore, you can also run it against encrypted password storage.

Basically, it can perform brute force attacks with all possible passwords by combining text and numbers. However, you can also use it with a dictionary of passwords to perform dictionary attacks.

Rainbow Crack

Rainbow Crack is also a popular brute-forcing tool used for password cracking. It generates rainbow tables for using while performing the attack. In this way, it is different from other conventional brute-forcing tools. Rainbow tables are pre-computed. It helps in reducing the time in performing the attack.

The good thing is that there are various organizations which have already published the pre-computer rainbow tables for all internet users. To save time, you can download those rainbow tables and use them in your attacks.

This tool is still in active development. It is available for both Windows and Linux and supports all latest versions of these platforms.

L0phtCrack

L0phtCrack is known for its ability to crack Windows passwords. It uses dictionary attacks, linux ftp client - Crack Key For U force linux ftp client - Crack Key For U, hybrid attacks and rainbow tables. The most notable features of L0phtcrack are scheduling, hash extraction from 64-bit Windows versions, multiprocessor algorithms and network monitoring and decoding. If you want to crack the password of a Windows system, you can try this tool.

Ophcrack

Ophcrack is another brute-forcing tool specially used for cracking Windows passwords. It cracks Windows passwords by using LM hashes through rainbow tables. It is a free and open-source tool. 

In most cases, it can crack a Windows password in a few minutes. By default, Ophcrack comes with rainbow tables to crack passwords of less than 14 characters which contain only alphanumeric characters. Other rainbow tables are also available to download.

Ophcrack is also available as LiveCD.

Conclusion

These are a few popular brute-forcing tools for password cracking. There are various other tools are also available which perform brute force on different kinds of authentication. If I just give an example of a few small tools, you will see most of the PDF-cracking and ZIP-cracking tools use the same brute force methods to perform attacks and crack passwords. There are many such tools available for free or paid.

Brute-forcing is the best password-cracking method. The success of the attack depends on various factors. However, factors that affect most are password length and combination of characters, letters and special characters. This is why when we talk about strong passwords, we usually suggest that users have long passwords with a combination of lower-case letters, capital letters, numbers and special characters. It does not make brute-forcing impossible but it does make it difficult. Therefore, it will take a longer time to reach to the password by brute-forcing. 

Almost all hash-cracking algorithms use the brute force to hit and try. This attack is best when you have offline access to data. In that case, it makes it easy to crack and takes less time.

Brute force password cracking is also very important in computer security. It is used to check the weak passwords used in the system, network or application.

The best way to prevent brute force attacks is to limit invalid logins. In this way, attacks can only hit and try passwords only for limited times.
