jenkins build - trying to execute shell command that include ssh command

Question

Background Information

I'm trying to get jenkins to execute the following shell commands as a part of my build process:

ssh root@10.111.11.11
rc-status

Right now it's failing with the following error message:

Host key verification failed.

Finished: FAILURE

What I've tried so far:

Unfortunately, it doesn't seem to tell me the line number in the known_hosts file that it doesn't like. On the same server that jenkins is running on, I can successfully ssh into the remote server 10.111.11.11 with no errors from a command prompt.

Could it be the fact that it's trying as "anonymous" instead of my id? If so, how do I resolve this? I can't see anything that allows me to specify what user to ssh as in jenkins.

Thanks.

It is the host key verification that fails, not user authentication. You can either ensure that the host key is stored in the known_hosts file (typically ~/.ssh of the user the Jenkins is running as), eg

ssh-keyscan 10.111.11.11 >> ~/.ssh/known_hosts

Or if you do not care about the security, you can disable the host key verification:

ssh -o StrictHostKeyChecking=no root@10.111.11.11

Other tips

If I got it right, you want to run command rc-status on the remote host. In that case, you should use ssh remote command execution, ie give the command as a parameter directly to the ssh:

ssh root@10.111.11.11 rc-status

For setting up the public key authentication I will recommend using SSH agent plugin . And if you have any further problems, it is always helpful to increase the ssh verbose level eg ssh -vvv ...
