I have a Slackware 9.1 installation on my home machine which connects
via an ISDN router to the internet. When I use ssh from this machine
the connection gets dropped after a very short idle period (around a
minute). When I use ssh from other machines (not from home) to the
same destination it doesn't timeout in nearly such a short time. Thus
I suspect that the Slackware firewall setup is dropping the
connection.

I don't think it's the router as the connection as a whole' stays up,
it's just the ssh that gets dropped with something like 'Connection
reset by peer'.

Where should I be looking for something like this?
