There is no requirement that "Host" is a lookup-able name and thus in general it is impossible to derive "HostName" from it. Moreover, you can use different "Host" names for the same "HostName" server, e.g., to setup different forwardings or use different user names: Host sa HostName server.example.com User admin Host sd HostName server.example.com User dan -- Regards, ASK
