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
If you're using Network Manager, then I think that's the expected behavior. See the thread on internet connection sharing on the Ubuntu site which describes related issues.
Network manager isn't intended for servers, but runs as a daemon, so possibly could be installed and running. What do you get from running
dpkg -l network-manager
eth0 is up and has both ipv4 and ipv6 (fe80::214:5eff:fe17:3970) addresses.
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?
