and how it worked for you: ssh password less connection works fine (using rsa public key). i followed below steps to do this: i followed below steps to resolve it till now but didnt work: - Create an SSH key pair (public/private) Ran the command “ssh-keygen -t rsa -C "Jenkins agent key" -f "jenkinsAgent_rsa" “ - Create an SSH credential in the Jenkins machine and put the private key there Created the credentials and put jenkinsAgent_rsa into it. - Create an SSH agent see https://github.com/jenkinsci/ssh-slaves-plugin/blob/master/doc/CONFIGURE.md#configure-launch-agents-via-ssh – This is creating a node which I didn’t do before – so I created the node and selected the credential with the private key. The verification strategy slect is non-verifying. - Select the SSH credential created before as credentials - Chose the verification strategy that you want, see the documentation, if you have problems start with the "Non verifying Verification Strategy" you can change it later - Add the public key on ~/.ssh/authorized_keys This was done but i am not able to establish the connection between jenkins and ssh server my ssh and jenkins server both are hosted on same ip
