hostname,ip shouldn't be a problem either. That's the correct format
for multiple entries on one line.
I often see "hostname.fqdn,hostname,ip" in known_hosts files.

Make sure that the host keys are loaded correctly.
You can see what was loaded by inspecting client._system_host_keys
    s.load_system_host_keys()
    for k in s._system_host_keys:
        print k


Can you connect without any error handling, and give us the stack
trace? I can only guess at what's printing  "server unknown".

What version of paramiko are you using?
