If using ksh, you can set the TMOUT variable in the .profile. See man ksh for more info.

There is also a tcp parameter called keepalive for this very purpose. See man ndd on how to set it, and ndd -h support for a complete list of settings.

David,
as suggested TMOUT can be set in the /etc/profile.
Also if do a
TMOUT=100
readonly TMOUT
export TMOUT
This sets the TMOUT variable to readonly, so users can't override.
But I think this timeout only applies whilst sitteing in a shell, if the user starts a vi session, I don't think they get timed out.

Arun,
your link refers to users accounts that have not be used for a time.Maybe wrong link?

David,
I think :
csh - autologout
ksh - TMOUT
bash - TMOUT
Posix - TMOUT

So it should work, but I think root may be excempt from the timeout.

Yes, TMOUT is the value for POSIX shells which includes sh (/usr/bin/sh), ksh and optional shells like bash. csh is not a POSIX shell and uses the autologout variable. In ALL shells, this timeoout value is for a shell prompt only. The timer starts when the shell waits for a command and is reset whenever anotherf command (like vi) is run. The shell cannot determine if a user has walked away leaving vi running. That takes a sysadmin to check.
