Hi Tim -
Is there any correlation between what machine you login from and
whether you have tickets? It sounds like you might be using a machine
that authenticates using tickets but doesn't delegate them - see
http://web.mit.edu/linerva/www/#ticket-forwarding for our documentation
on how to fix that.
If you're not forwarding tickets, you can't get tokens when you login,
which are the credentials that authenticate you to AFS. Without tokens,
you can't read your dotfiles. Your dotfiles include the Athena standard
dotfiles, which set your prompt to "athena%". The other prompt you're
seeing is actually the tcsh default prompt.
As for your session freezing, that sounds like you're losing your
connection to Linerva. Since ssh happens over a single long-lasting
connection (as opposed to protocols like HTTP which are effectively
stateless), interruptions in your network connectivity, especially ones
that result in your IP address changing, can result in symptoms like
that. Do you notice any other brief interruption in your network
connection when you get disconnected like this?
