Using the secure shell (ssh) Utility to Run CL Commands Remotely Through an SSH
Connection

Troubleshooting


Problem

The document describes how to run CL commands remotely through an SSH connection.

Resolving The Problem

The SSH utility has several switches and parameters that allow you to run a shell command remotely
without first entering the remote shell. The following examples show you a couple of different ways to use this function:

  • The following command establishes an SSH session under user profile BARLEN2 to the i5OSP2 system and submits a backup job in i5/OS:

ssh -T barlen2@i5osp2 'system "SBMJOB CMD(CALL PGM(TOOLS/BACKUPLIBS) PARM(*ALL)) JOB(BACKUP)" '

As a result of this command, the shell displays the following i5/OS message that was issued on the remote system:

CPC1221:  Job 015242/BARLEN2/BACKUP submitted to job queue QBATCH in library QGPL.

The system command is used in the i5/OS PASE shell to run i5/OS commands.
  • In this example, the Display Message (DSPMSG) command for displaying the QSYSOPR message queue is run:

ssh -T barlen@i5osps2 'system "DSPMSG QSYSOPR" '

As opposed to the first example where you received the message about the submission of the job, the DSPMSG command returns the
output to the source system's i5/OS PASE shell.

    CPC9802: Printer output created.

Note: These two examples always require you to enter a password when connecting to the remote system. In many cases, this is not desirable because some commands should be run in unattended or batch mode. Automatic sign-on can be achieved with SSH by using public key authentication.
