Hi everybody,

I had been connecting laptop and desktop using PLIP for ages without a
single problem. Then I got a new laptop and upgraded to ethernet.
Although the speed is amazing compared to PLIP, the transfer of even
moderately sized files (from 2M about) sometimes hangs the connection.
This happens as well with ftp than nfs transfers. A file diff accross
the network may also hang. If I manually remove and restart the network
interfaces and routes on the desktop system, it wakes up. But then next
time the transfer hangs, the full desktop system will hang as well, with
a hard reboot necessary.
All other network applications I have tried work perfectly (telnet,
masquerading, rdate). Removing the gateway does not help.
On Windows XP / 98 the problem does not show, file transfer is OK.
I have been like this for months. I didnt find anything on group or web
archives.
I have strictly no clue. Could someone help me, or tell me where to ask
if this is not the right place ?

There are many possibilities here, bad cables, bad hardware,
bad/misconfigured drivers, etc.

I'm sure you've checked all the usual stuff. I would suggest checking the
memory with memtest-86, I've seen problems like this before and if it wasn't
a bad NIC or driver problem, it was usually the system memory had an obscure
flakey error.
