X clients die after a while

[Eric Hanchrow]

The following message is a courtesy copy of an article
that has been posted to comp.security.ssh as well.

I have sshd (from openssh 1.2.3) running on my home machine (Debian
GNU/Linux 2.2), and when I'm at work I like to start an Emacs like
this:

        ssh -f -l offby1 my.home.machine.net emacs

(At work I use ssh 1.2.27 from http://www.cs.hut.fi/ssh on RedHat
6.2.)

This works fine, except: often, after iconifying Emacs and then not
using it for a while (an hour or two), I will restore it, and it will
then vanish.  At the shell prompt from which I started the ssh client,
I will see a message that says `read from my.home.machine.net:
connection reset by peer'.  There will be no log message on the server
machine to indicate what went wrong.

I've tried restarting the daemon with the line `KeepAlive no' in
/etc/ssh/sshd_config, but that made no difference.

I haven't yet tried running the daemon with debugging turned on.
Until I do that, though, can anyone suggest why this might be
happening?

Thanks
