Manage your Red Hat Enterprise Linux WorkSpaces

As with Windows and Amazon Linux WorkSpaces, Red Hat Enterprise Linux WorkSpaces are domain joined, so you can use Active Directory Users and Groups to:

  • Administer your Red Hat Enterprise Linux WorkSpaces

  • Provide access to those WorkSpaces for users

You can manage Red Hat Enterprise Linux WorkSpaces with Group Policy by using ADsys. See the Red Hat Enterprise Linux Active Directory integration FAQ for more information. You can also use other configuration and management solutions, such as Landscape and Ansible.

Control DCV behavior on Red Hat Enterprise Linux WorkSpaces

The behavior of DCV is controlled by configuration settings in the wsp.conf file, which is located in the /etc/wsp/ directory. To deploy and enforce changes to the policy, use a configuration management solution that supports Red Hat Enterprise Linux. Any changes take effect when the agent starts up.

Note

If you make incorrect or unsupported changes to the wsp.conf policies may not be applied to the new established connections to your WorkSpace.

The following sections describe how to enable or disable certain features.

Enable or disable clipboard redirection for Red Hat Enterprise Linux WorkSpaces

By default, WorkSpaces supports clipboard redirection. Use the DCV configuration file to disable this feature, if needed.

To enable or disable clipboard redirection for Red Hat Enterprise Linux WorkSpaces

  1. Open the wsp.conf file in an editor with elevated rights by using the following command.

    [domain\username@workspace-id ~]$ sudo vi /etc/wsp/wsp.conf

  2. Add the following line to the end of the [policies] group.

    clipboard = X

    Where the possible values for X are:

    enabled — Clipboard redirection is enabled in both directions (default)

    disabled — Clipboard redirection is disabled in both directions

    paste-only — Clipboard redirection is enabled and only allows you to copy contents from the local client device and paste it to the remote host desktop

    copy-only — Clipboard redirection is enabled and only allows you to copy contents from the remote host desktop and paste it to the local client device

Enable or disable audio-in redirection for Red Hat Enterprise Linux WorkSpaces

By default, WorkSpaces supports audio-in redirection. Use the DCV configuration file to disable this feature, if needed.

To enable or disable audio-in redirection for Red Hat Enterprise Linux WorkSpaces

  1. Open the wsp.conf file in an editor with elevated rights by using the following command.

    [domain\username@workspace-id ~]$ sudo vi /etc/wsp/wsp.conf

  2. Add the following line to the end of the [policies] group.

    audio-in = X

    Where the possible values for X are:

    enabled — Audio-in redirection is enabled (default)

    disabled — Audio-in redirection is disabled

Enable or disable video-in redirection for Red Hat Enterprise Linux WorkSpaces

By default, WorkSpaces supports video-in redirection. Use the DCV configuration file to disable this feature, if needed.

To enable or disable video-in redirection for Red Hat Enterprise Linux WorkSpaces

  1. Open the wsp.conf file in an editor with elevated rights by using the following command.

    [domain\username@workspace-id ~]$ sudo vi /etc/wsp/wsp.conf

  2. Add the following line to the end of the [policies] group.

    video-in = X

    Where the possible values for X are:

    enabled — Video-in redirection is enabled (default)

    disabled — Video-in redirection is disabled

Enable or disable time zone redirection for Red Hat Enterprise Linux WorkSpaces

By default, the time within a Workspace is set to mirror the time zone of the client that is being used to connect to the WorkSpace. This behavior is controlled through time zone redirection. You might want to turn off time zone direction for reasons such as the following:

  • Your company wants all employees to work in a certain time zone (even if some employees are in other time zones).

  • You have scheduled tasks in a WorkSpace that are meant to run at a certain time in a specific time zone.

  • Your users travel a lot and want to keep their WorkSpaces in one time zone for consistency and personal preference.

Use the DCV configuration file to configure this feature, if needed.

To enable or disable time zone redirection for Red Hat Enterprise Linux WorkSpaces

  1. Open the wsp.conf file in an editor with elevated rights by using the following command.

    
[domain\username@workspace-id ~]$ sudo vi /etc/wsp/wsp.conf

  2. Add the following line to the end of the [policies] group.

    
timezone-redirection = X

    Where the possible values for X are:

    enabled — Time zone redirection is enabled (default)

    disabled — Time zone redirection is disabled

Enable or disable printer redirection for Red Hat Enterprise Linux WorkSpaces

By default, WorkSpaces supports printer redirection. Use the DCV configuration file to disable this feature, if needed.

To enable or disable printer redirection for Red Hat Enterprise Linux WorkSpaces

  1. Open the wsp.conf file in an editor with elevated rights by using the following command.

    [domain\username@workspace-id ~]$ sudo vi /etc/wsp/wsp.conf

  2. Add the following line to the end of the [policies] group.

    remote-printing = X

    Where the possible values for X are:

    enabled — Printer redirection is enabled (default)

    disabled — Printer redirection is disabled

Enable or disable disconnect session on screen lock for DCV

Enable disconnect session on screen lock to allow your users to end their WorkSpaces session when the lock screen is detected. To reconnect from the WorkSpaces client, users can use their passwords or their smart cards to authenticate themselves, depending on which type of authentication has been enabled for their WorkSpaces.

By default, WorkSpaces doesn’t support disconnecting session on screen lock. Use the DCV configuration file to enable this feature, if needed.

To enable or disable disconnect session on screen lock for Red Hat Enterprise Linux WorkSpaces

  1. Open the wsp.conf file in an editor with elevated rights by using the following command.

    [domain\username@workspace-id ~]$ sudo vi /etc/wsp/wsp.conf

  2. Add the following line to the end of the [policies] group.

    disconnect-on-lock = X

    Where the possible values for X are:

    enabled — Disconnect on screen lock is enabled

    disabled — Disconnect on screen lock is disabled (default)

Grant SSH access to Red Hat Enterprise Linux WorkSpaces administrators

By default, only assigned users and accounts in the Domain Admins group can connect to Red Hat Enterprise Linux WorkSpaces by using SSH. To enable other users and accounts to connect to Red Hat Enterprise Linux WorkSpaces using SSH, we recommend that you create a dedicated administrators group for your Red Hat Enterprise Linux WorkSpaces administrators in Active Directory.

To enable sudo access for members of the Linux_WorkSpaces_Admins Active Directory group

  1. Edit the sudoers file by using visudo, as shown in the following example.

    
[username@workspace-id ~]$ sudo visudo

  2. Add the following line.

    
%Linux_WorkSpaces_Admins ALL=(ALL) ALL

After you create the dedicated administrators group, follow these steps to enable login for members of the group.

To enable login for members of the Linux_WorkSpaces_Admins Active Directory group

  1. Edit /etc/security/access.conf with elevated rights.

    
[username@workspace-id ~]$ sudo vi /etc/security/access.conf

  2. Add the following line.

    
+:(Linux_WorkSpaces_Admins):ALL

With Red Hat Enterprise Linux WorkSpaces you do not need to add a domain name when specifying username for SSH connection, and by default, password authentication is disabled. To connect via SSH, you needs to either add your SSH public key to $HOME/.ssh/authorized_keys on your Red Hat Enterprise Linux WorkSpace, or edit /etc/ssh/sshd_config to set PasswordAuthentication to yes. For more information about enabling SSH connections, see Enable SSH connections for your Linux WorkSpaces.

Override the default shell for Red Hat Enterprise Linux WorkSpaces

To override the default shell for Red Hat Enterprise Linux WorkSpaces, we recommend that you edit the user's ~/.bashrc file. For example, to use Z shell instead of Bash shell, add the following lines to /home/username/.bashrc.


export SHELL=$(which zsh)
[ -n "$SSH_TTY" ] && exec $SHELL
Note

After making this change, you must either reboot the WorkSpace or log out of the WorkSpace (not just disconnect) and then log back in for the change to take effect.
