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?

Just for grins I googled ssh timeout, found lots of leads.

I did that long ago and it's not very helpful.

Firstly you get thousands of hits which suggest using the ssh
'keepalive' parameter which, if you read the manual page, has nothing
whatsoever to do with idle timeouts.

Secondly I'm pretty sure my problem is nothing at all to do with ssh
as ssh connections from other systems (e.g. here at work) don't time
out in the same way even though they're connected to the same
destination. The idle timeouts seem to be related to Slackware
(probably) or my ISDN router (less likely).

I had a long look through the Slackware documentation on my system
last night and didn't really drag up anything very useful, that's why
I asked here. I have tried the 'obvious' approaches.
