Hi All, first time poster on here and first time user of IBM servers.
I'm having a few problems with the interface card on my server, I have installed Ubuntu 8.04 and also tried 9.04 but having the same problem, install goes well and discovers that I have two Ethernet adapters (install thinks its two) which are eth0 and eth1, I get asked which one I would like as the primary card and I select eth0.
Install goes well and finishes with no problems, I very LAN connectivity by using ping, so as it stands I have eth0 with an IP address of 192.168.3.242.
Now I want to add an IP address to eth1 so I issue the command
'ifconfig eth1 192.168.3.240'
'ifconfig eth1 netmask 255.255.255.0'
'ifconfig eth1 up'
Which at this point I can ping 192.168.3.240, problem is I have not inserted the Ethernet cable, and when I do insert it eth0 drops.
Has anybody come across this issue before and if so I would I go about resolving.
Many thanks for reading and if you need more information I will happily provide

Re: IBM x3550 7978 Ubuntu NIC issues2009-10-30T10:13:42ZThis is the accepted answer. This is the accepted answer.Just loaded Webmin and looked at the networks side of things and have this.
Name TYPE Address NETMASK STATUS
eth0 Ethernet 192.168.3.243 255.255.255.0 Up
Ethernet fe80::214:5eff:fe17:3970 64 Up
eth1 Ethernet 192.168.3.140 255.255.255.0 Up
Loopback ::1 128 Up
lo Loopback 127.0.0.1 255.0.0.0 Up
As you can see on eth1 looks different to eth0, there is no MAC address and also an added loopback.

eth1 is up and has an assigned IPv4 address and a default IPV6 address (::1).
lo is your local loopback address (127.0.0.1)
There are no MAC addresses displayed.
Looks like you have both interfaces up. What symptom makes one appear down?

At the minute the only cable that is plugged in is eth0 and I can ping both addresses.
