Subject:  Stalled connection (need help to debug)

Hallo.

I have a very strange problem.

Server (with Debian Etch) was running for 80 days perfectly. Then, (after
some lighting, i believe) i noticed, that connection, that isn't active
(i.e. is not transferring something) frizzes (on linux) and then
dies (connections reset).

Logs are empty. Ping is working, reconnection is OK. But if it's not
active ==> same stall.

Server is pretty far way and after i tried everything (reconfigure IF,
different client OSes), i've rebooted it. Still the same problem. I
didn't do power cycle though.

I use this server as my Internet ant (it's flower.upol.cz, BTW).
I do ssh && screen -x to work on it. The only way i still can do this,
it's my clock.sh script (updates tty with current time after 1 sec):

$ ssh && clock.sh && exec screen -x

Any advise on how to debug this will be very appreciated. Thanks.
