1. Unable to keep Linux box on network - keeps "disappearing"
I'm having a bit of trouble with network configuration here, setting
up linux on a 386 here. Basically, it doesn't stay visible on the network
for longer than a few minutes. No problems connecting to other machines
from this 386 using ping, nslookup, telnet. With other machines
connecting to here though (i.e., ping), the 386 "disappears" from the
network after a few minutes. After that, nothing can to connect it until
I run nslookup or ping (as an example) - then its is "visible" again, but
only for a few minutes.
I've skimmed through the NET-2 howto and parts of the Net Admin Guide
without finding anything. I tried using tcpdump/icmpinfo to see what's
happening, but they aren't too helpful (it would be more useful if I had a
second machine to run it on to check the 386 - as it is, running tcpdump
on the 386 with tcpdump dst host 18.104.22.168 stops generating messages
once the 386 disappears from the network.) I can keep the machine visible
if I run nslookup on a random machine continuously in a loop at minute

I have source/patches for 1.2.11 and 1.3.9 of the kernel, but wanted
to get this problem fixed first (it would be nice to be able to dial-in
and recompile the kernel while at home.)
Any ideas on what the problem is or what else I should try to
determine the cause of the problem? (I remember reading a similar problem
mentioned many, many months ago here, but cannot remember the outcome.) I
was going to look for another ethernet board on Monday to test with. Is
there any other information I need to provide which would be helpful?
summary/solution of the problem. Thanks-
