Calling SSH command from Jenkins

ssh jenkins rtc rational-team-concert

Jenkins keeps using the default "jenkins" user when executing builds. My build requires a number of SSH calls. However these SSH calls fails with Host verification exceptions because i haven't been able connect place the public key for this user on the target server.

I don't know where the default "jenkins" user is configured and therefore cant generate the required public key to place on the target server.

Any suggestions for either;

  1. A way to force Jenkins to use a user i define
  2. A way to enable SSH for the default Jenkins user
  3. Fetch the password for the default 'jenkins' user

Ideally I would like to be able do both both any help greatly appreciated.

Solution: I was able access the default Jenkins user with an SSH request from the target server. Once i was logged in as the jenkins user i was able generate the public/private RSA keys which then allowed for password free access between servers

Because when having numerous slave machine it could be hard to anticipate on which of them build will be executed, rather then explicitly calling ssh I highly suggest using existing Jenkins plug-ins for SSH executing a remote commands:

  • Publish Over SSH - execute SSH commands or transfer files over SCP/SFTP.
  • SSH - execute SSH commands.
