Dear Donald, 


thanks a lot for your help. I just found out what the problem
has been.
I got fooled by two concurrent mistakes. You had been completely
right with name-server and tcpdump. Though a name-server was
accessible
via gateway and yp, tcpdump probably only looks in /etc/hosts.
The 
second problem was that I made tcpdump -i eth1 and then pulled
the
cable on eth0 which immediately has frozen tcpdump. This problem
would
have not been apparent if I had shut eth0 down before pulling
the cable.

Still, what is not understood by me, is, why did ping {ip of the
gateway}
also fail? ping should not do a name-server lookup? It might be
possible
that Windows 2000 (the driver from 3Com) changed something in
the EEPROM
of of card. But vortex-diag and mii-diag give the same answer,
so I still
don't really understand why I got so much trouble.


I am happy that things are working now and if you ever will
visit
Bonn (former capital of Germany) let me know - I would be happy 
to invite you for a drink dinner or what else.


Thanks a lot

Uwe
