Ärende: Linux is stealing the internet from eCS...
==================================================

comp.os.os2.networking.tcp-ip:181
From: rcpj@panix.com (Pierre Jelenc)

I have just set up a Linux machine running Ubuntu 10.10/Gnome (that's the 
way it came, I haven't even attempted to modify anything.) It plugs into 
port #2 of a Netopia router, while the eCS machine uses port #1. It seems 
that almost as soon as I do something via the internet on the Linux 
machine, it disables completely internet access from the eCS one: http, 
ssh, telnet, ftp all time out with no explanation, while things look OK on 
the Linux side.

To get eCS back on line, I must not only unplug the cable from the Linux 
box, but reboot the router as well.

I have an old Mac laptop that I used to use together with the same eCS 
machine and the same router without any problem, so it's not just having 
two computers going through the router that causes the trouble. Also, when 
the eCS side becomes disabled, it appears to be disabled at the computer 
itself, because I cannot even reach the router via its web interface: such 
an attempt times out, even though there's no traffic beyond the router.

I have swapped the cables at the router ports (there are 4 ports, and I 
tried several combinations of all of them) and rebooted everything but 
that does not help.

One peculiar thing is that both computers claim to be at 192.168.1.105 
(from ifconfig lan0/eth0) which would point to a competition, but why 
would they both get the same address? Why 105 rather than 100 or 101? Why 
does Linux always seem to win regardless of whether it is plugged in port 
#1 or #2, or whether it is not even plugged in until well after eCS has 
already grabbed 192.168.1.105 and been shown to connect without problem?

If this is the cause of the problem (rather than a symptom) I should be 
able to force an address via ifconfig, but should I do it on both 
machines, and how much should I specify? The syntax of ifconfig has so 
many parameters!

Thanks,

Pierre
