ssh hangs after about 15 minutes for each connection
Both I and a friend have noticed that our slogin connections
hang (timeout?) after not using our connections for about 15 minutes.
I noticed this hanging after I upgraded from potato to woody
about 10 months ago, and my friend noticed this hanging
after he upgraded from potato to woody about 3 months ago.
For example, from my office-computer,
slogin -X my-home-computer
after which I seem to remain connected as long as I interract with
the connection for about a 15 minute period.
But if I do not interract for about 15 minutes,
then I will no longer get any keyboard interraction however many
minutes/days pass, including no response from ctl-C, ctl-D, ctrl-Z.
I can only get my local xterm back, and I do that with
However, my remote computer [home computer in my case] continues
to run the corresponding "ssh" process.
After using "~." on my local computer [office computer in my case],
I merely accumulate these ssh processes
on my remote computer [home computer in my case],
a process clutter that I eventually kill after a week.
I have even tried changing on my remote [home] computer
/etc/ssh/ssh_conf and /etc/ssh/ssh_conf with
but my slogin still hangs after about 15 minutes of non-use.
I notice no aberrant log entries with the pattern "ssh".
Something seems to have changed between the potato and the woody
versions of ssh.
I welcome any suggestions.
