ethernet not working

[karozans]

Hi everyone. I am kind of a novice with linux.

Anyway, I have a special board with 2 embedded ethernet nics.

I am running a special modified version of SUSE linux.

One of them (eth0) is working fine.

the other one (eth1) does not work. It does not show up at all.

What could be wrong?

eth0      Link encap:Ethernet  HWaddr 00:10:EC:01:00:0B
          inet addr:9.11.226.133  Bcast:9.11.226.191  Mask:255.255.255.192

          collisions:0 txqueuelen:0
          RX bytes:16228 (15.8 Kb)  TX bytes:16228 (15.8 Kb)

I kept checking on this issue.

when I run...

dmesg |grep -i eth0

I get information returned. When I run

dmesg |grep -i eth1

Nothing is returned.

I also looked at the device tree for this linux build.

I see entries for eth0 and eth1. Although I do not know what the values should or should not be.

Try adding eth1 manually first:

/sbin/ifconfig eth1 192.168.1.1 netmask 255.255.255.0
/sbin/ifconfig

If that works you'll need to add the interface manually, unless you have a dhcp server-

[karozans]

SIOCSIFADDR: No such device
eth1: unknown interface: No such device
SIOCSIFNETMASK: No such device

OK, that makes sense.
Before going into the various troubleshooting options, have you tried booting the system with a live CD, such as Knoppix? Try a few so see if any pick up both interfaces. If none do then the hardware on eth1 may not be working. If some do then it'll be a driver issue. You're not running any virtual systems are you (Xen, VMware etc)?
