I used to do this, depending on what IP I logged in from. In some cases it
would get confused when I went from one machine to another, but mostly it
However, more recently, I rarely run X programs on another system. SSH X
forwarding works great for that though, as other folks mention.
Other options are to set up AllowEnv and then export an environment
variable on the client. That can even go through multiple SSH hops. You
could also use the "command=" stuff in your authorized_keys file to set up
environment variables depending on what key you are using. Then just have
different keys on the different machines you are using.
The Roman Rule: The one who says it cannot be done should never
interrupt the one who is doing it.
