[comp.protocols.kerberos] how can I log into athena from u.washington?

wildfire@U.WASHINGTON.EDU (Darkstar) (01/06/91)

Hi, I am a MIT student and have an account at athena.mit.edu
Currently I am taking a break at University of Washington, but I like to keep intact with athena.
Everytime I try to log into athena using my own login name and pass word,
athena would let me in but then would disconnect me after 60 seconds.
The error message is
athena.dialup.mit.edu: Network is unreachable
Connection closed by foreign host.

During the first 60 seconds, I am able to execute any command as if I was on athena itself.
My question is: What can I do to stay on Athena for longer than 60 seconds?
