No offense, but start with reading the error message.

Have you recently reinstalled "workstationB"?

Now it looks like I have to learn about rsa keys and ssh.

A point in the right direction would be appreciated.

Thank all.

Is this the first time you have logged into workstationB from your server?

Are you using keys or passwords or both on your server?

hint: /etc/ssh/sshd_config file should let you know

If you have logged in before and not changed anything since, it would be unusual to see this type of message.

Are both of these boxes local to you and not out on the internet somewhere?
