PSM for SSH installation (2023)

Before you begin

  • Make sure you review the information in PSM for SSH pre-installation tasks.

  • Staring from version 12.0, the default installation mode of PSM for SSH is set to Integrated (InstallCyberArkSSHD = Integrated). The Integrated mode preserves the native SSHD on the PSM for SSH machine and interacts with it using dedicated PAM (Pluggable Authentication Module) and NSS (Name Service Switch) modules. This makes the product less invasive and enables each customer to perform the desired configurations and updates according to organizational policies, without making an impact on the PSM for SSH functionality.

    When installing PSM for SSH in Integrated mode, we highly recommend that the SSHD service is hardened locally according to your organizational and industry best practices.

    PSM for SSHsupport on SUSE does not include the installation of the CyberArk SSHD service component. If you install PSM for SSH with InstallCyberArkSSHD = Integrated, after the installation you must follow the procedure described in Enable Integrated mode on SUSE.

    To review the use of the SSHD service and the PSM for SSHfeatures that are affected by this service, see InstallCyberArkSSHD parameter.

General installation problems

Problem: During installation, the following message was written in the log file:
“Make sure that the InstallationFolder and the InstallCyberarkSSHD parameters were set correctly in the /var/tmp/psmpparms configuration file.”
Solutions:
Make sure the /var/tmp/psmpparms file is in Unix format. If not, run dos2unix.
Make sure that the directory specified in the InstallationFolder parameter exists.
Make sure the InstallCyberarkSSHD parameter is set with a Valid value (Integrated, Yes, or No).
Problem: During installation, the following message was written in the log file:
“error: Installation failed. Reason: installation parameters file [/var/tmp/psmpparms] doesn't exist.”

TCP port 18923 is used by another process on the local machine

Problem: The TCP port 18923 is being used by another process on the local machine and cannot be used by PSM for SSH to listen for additional command requests.
Solution: Stop the psmpsrv service and use netstat –na to check whether the port is being used. If the port is being used by another process, configure PSM for SSH to use a different TCP port. For more information, refer to Privileged Session Manager for SSH parameter files.<![CDATA[]]>

The PSM for SSH user has already been created in the Vault

Problem: You specified the name of a PSM for SSH user who has already been created in the Vault.
Solution: A new credentials file will not be created for this user. You need to create the credentials file manually so that PSM for SSH can connect to the Password Vault and work properly. For more information about creating credentials files, refer to User credential files. <![CDATA[]]>

Problems during service startup

Problem: PSM for SSH failed to start.
Solution: Open the console log, PSMPConsole.log, in the logs folder and identify the relevant errors.

Restore PSM for SSH connectivity

Problem:

<![CDATA[]]>PSM for SSH can sometimes be disconnected from the Vault. You may need to reset the PSM for SSH credentials.

The most common reasons are:

  • Network issues. First check your network. If there are no issues, continue below.

  • Sync issues. PSM for SSH can no longer authenticate to the Vault.

Solution:

Reset the PSM for SSH credentials:

In the PrivateArk Administrative Client:

  1. Log onto the Vault with the Vault user who installed PSM for SSH.

  2. Change the passwords of the following users:

    • appuser

    • gwuser

    • adbuser

On the PSM for SSH server machine:

  1. Stop the PSM for SSH Server service.

  2. Go to the path where the cred files are located.

    • For appuser and gwuser - /etc/opt/CARKpsmp/vault

    • For adbuser - /etc/opt/CARKpsmpadb/vault

  3. Use the CreateCredFile utility to create new credentials files for appuser, gwuser, and adbuser.

    For version 12.1 and earlier:

    CreateCredFile <filename> Password –Username <username> -Password <password>

    For version 12.1.1 and later:

    • For appuser:

      ./CreateCredFile psmpappuser.cred Password -Username <appusername> -Password <app_user_password> -OSUsername root -AppType PSMPApp -ExePath /opt/CARKpsmp/bin/psmpserver -EntropyFile
    • For gwuser:

      ./CreateCredFile psmpgwuser.cred Password -Username <gwusername> -Password <gw_user_password> -OSUsername root -AppType PSMPApp -ExePath /opt/CARKpsmp/bin/psmpserver -EntropyFile
    • For adbuser:

      ./CreateCredFile psmpadbridgeserveruser.cred Password -Username <appusername> -Password <adb_user_password> -OSUsername root -AppType PSMPApp -ExePath /opt/CARKpsmpadb/bin/psmpadbserver -EntropyFile
  4. Start the PSM for SSH service.

For more information, refer to User credential files.
