:Again, Matt, with all due respect, please do not post your operational
:habits as universals. Somebody who keeps a session to a server around
:so they can see syslog messages if there's a problem may have an idle
:connection for weeks.
:
:In case you still doubt the existance of such a person, I give you a
:counterexample. Having just spoken with nemo, I am quite certain that
:he is alive and well, and from my dealings with him have no doubt he
:would become somewhat miffed if I were to kill off several of his
:sessions.

:Cheers,

Turning on keepalives would not change the effectiveness of leaving
these xterms open if syslog is being tailed. If there is a network
problem, the connections will terminate from a data timeout due to the
syslog messages being transmitted over the connection long before it
would terminate from a keepalive timeout.
I'm not saying that a person fitting the profile doesn't exist, I'm saying
that there are so few of these people that the benefits outway the issues
by several orders of magnitude.
I can only repeat: Turn them on and see if they effect you. You will
almost certainly find that they do not effect you. Ask your friend to
turn them on and see if they effect him. If he's tailing syslog in those
windows they won't effect him.
