Introduction

  • The JS7 - JITL SSH job allows execution of shell commands and scripts on a remote host running an SSH server without requiring a local SSH client to be installed.
  • To log in to remote systems using a pair of keys. in this example we added the client's public key to the remote server with the authorized_keys file in the .ssh/ sub-directory of the target account's home directory.

Workflow

The 11_AgentlessScheduling folder includes two workflows that use the JITL com.sos.jitl.jobs.ssh.SSHJob class with the arguments host, port, auth_method, command etc. to login to the SSH server:

  • jdSSHPublicKeyAuthentication: In this workflow, the command parameter is used to execute a single command on the remote server. 
  • jdSSHScriptPublicKeyAuthentication: In this workflow, the command_script parameter is used to run a full-blown script on the remote server. You can add the contents of a shell script to the command_scriptparameter it will execute the script on the remote server.
