Enforcing session timeout under csh

[Phil Fernandez]

One of my users with a Sun 3/60 wishes to enforce an idle session
timeout under SunOS 3.5.  That is, after a login session has been idle
for, say, 10 minutes, he wants the line (most likely a telnet
connection) to be automatically logged out.  Should work for any
shell.  Is there a way to do this?  How?

Please send mail to me directly; I don't regularly read this
newsgroup.

Thanks!
