[vox-tech] Another Round of eth0 Problemas

Back in August '04 we ran this thread
<http://ns1.livepenguin.com/pipermail/vox-tech/2004-August/009158.html> into
the ground.
Now I have another problem with an OptiplexGX270 with an identical (AFAICT)
H/W setup as the GX270 that you met in the previous thread.
Your help is appreciated.
Context:
Optiplex GX270
P4 3.0 GHz/1GB DDR RAM
Intel 82540EM
e1000 driver
Debian Sarge
jkaralius at mmagdb:~$ uname -a
Linux mmagdb 2.4.24-1-386 #1 Wed Feb 18 19:44:56 EST 2004 i686 GNU/Linux
jkaralius at mmagdb:~$
I've done the cable swapping, ping, google, /etc/init.d/networking
stop|start|restart, ping, google, check route/ifconfig, ping, google, insmod
e1000/lsmod, google, and head-banging routine to no avail. Then I googled
some more...
@possibilities = ('swap cables',
'/etc/networking stop|start|restart',
'check route -n, ifconfig -a',
'insmod e1000, lsmod',
);
foreach $thing_to_check(@possibilities){
do($thing_to_check);
ping($server);
check($webpage);
google(@errors);
bang_head($self);
}
This time the box is running as a desktop server for a Zope/Plone intranet
portal and we are experiencing intermittent connectivity to that machine.
Plone serves up just fine when physically logged in and sitting at the
server, but other WinXP clients cannot access the site reliably. I
routinely log into the server using PuTTY from my WinXP box and get kicked
off when the connection goes down. I can ssh into the server from another
Linux machine a little more reliably, but I've been disconnected from that
machine as well.
jkaralius at mmagnet:~> ssh mmagdb
6147: ssh: connect to address 207.247.90.26 port 22: Connection refused
The lights from the onboard gigE port seem to be on all the time, no
flickering that I've seen. I can't seem to recreate the problem or identify
a pattern of occurrence.
The possibilites?:
Bad switch port - I tried swapping ports on the switch
faulty cable - I swapped cables, no difference (CAT6, BTW)
noisy kbd cable - see dmesg output below
faulty NIC - I do not have an extra NIC to try out - (has been ordered -
Note to self: keep a few of these lying around JIC)
kernel - Have not and do not know what to look for.
memory issues? -

Swap: 8779472 20528 8758944
high network traffic - How does you define 'high'? IMO, this is not
likely, since we only have like 6 regular users and rarely are more than 2-3
logged into the site at the same time. We had the same problem over this
weekend with only one user.
wrong|corrupted|not installed driver - the latest debian package
(e1000-common) is installed
mmagdb:/home/jkaralius# insmod e1000

insmod: a module named e1000 already exists
mmagdb:/home/jkaralius#
I can't see any runaway processes in 'top'.
Here's some output from relevant utilities
