Hi Jonathan Thanks for your reply. You wrote:

The existing slaves aren't using public key authentication so they must be using passwords. How would password authentication normally be set up to work in Jenkins?

I don't recall doing this for the other slaves, and they have no .pub files. Do I need to copy the SSH key from the master to the slave? You need to configure the ssh client on the Jenkins machine to authenticate to the ssh server on the slave machine. How did you do this for the working slaves? If they're not using public key authentication, they must be using a different mechanism, like passwords. First, figure out how to log into the slave directly by running ssh as the Jenkins user. Here's a HOWTO for configuring public key authentication. There are numerous other HOWTOs out there and little, if any, of this is specific to an operating system. You don't want to set a passphrase on the private key used to authenticate to a Jenkins slave. <URL:https://help.ubuntu.com/community/SSH/OpenSSH/Keys> -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
