Pat,
true as far as it goes, but unfortunately it doesn't go far
enough. SSH_CLIENT is set to ltspl server address, not workstation.
Setting up environment on turtle is fine only if the users never move to a

now, but i really need a dynamic setup. you did get me to start rereading
the o'reilly book though. thank you, julius
