Two Net Cards problem
I have just tried adding a second network card to my linux machine, and am
having a few problems.
I am running all hamm software, although I think some modules have been
updated since I installed it some weeks ago. The original card in the
machine was a basic NE2000 clone. I have added a Racal Interlan NI6510ES.
I have had both cards working individually in the system without problems.
On boot up, both cards were recognised automatically, I did not need to
change the con figuration. The Lance drivers see the Racal card some time
before the ne drivers see the NE2000 clone, and they are given names eth0
and eth1 respectivly. Originally, with the NE2000 only in the system, this
was eth0.
I adjusted /etc/init.d/network manually to move the eth0 code to eth1, for
the internal network, and added the code for eth0 for my internet link. I
had to do this because only the NI6510 has the utp connection I need for
the external link.
Now, the internal network still works, on eth1, but I can't get any life
out of the internet link. I know the link itself is OK, as it's currently
in use from an NT machine that I anm trying to replace here. I'm just
plugging it in when I want to test it. Pinging any external address,
including same-subnet stuff, doesn't get any responses, and it seems from
ifconfig that the packets are going out the wrong interface.
I know it must be something simple I have done wrong, but I can't for the
life of me see what. I'm sure it will be obvious to someone there..
Thanks
Rob.
