ubuntu network setup
 

I am/used to be a big redhat guy, but testing Ubuntu server for a few reasons and pretty happy with it. By recommendation from the lq forum, clonezilla seemed to be the right way to go to dup this machine.

Well I did it last night, 2nd server came up, I changed IP and hostname but network is not starting. They are the same Intel cards. Now in redhat, I would look in the conf file at the mac address as that was prob it, or more basic run the cli setup.

Are there any Ubuntu server (or even desktop guys) that know enough at that non X level that can help out. I am getting the following error on a network restart;

eth0: ERROR while getting interface flags: No such device
SIOSIFADDR: No such device

I can't see hardware settings or anything in that interfaces file, so a bit lost on this one. I would hate to have to stage these servers from scratch with all the customization already done.

Thanks.

I would definitely make sure the card is seated correctly in the box. I have seen this time and time again with ubuntu users at my office. if that does not work you may have a driver issue. in that case just copy the driver from the original box as u said that the same card is being used.

Sorry this can usualy be found in something like /src/kernelxx/drivers/net/ as most distors store in that area(have never used ubuntu )

C'mon. Let's re-look at the post.

This was a working server, a Dell PowerEdge 1850 (on board nic so no re-seating needed) host and client. A CD was put in along with an external USB device which had the hosts image.

Booted off CD. Re-imaged hard drive. Rebooted, all looks to be working (lspci won't show a device if it's not there). As for the copy the driver over, I also mentioned the drive was cloned using clonezilla so what need would there be to copy the drivers over if they are the exact image?

Thanks for the replies, but need something a bit more OS wise. I am betting it's a MAC issue, so looking around at the macchanger, etc. but don't know enough how/where ubunutu stores as their not in the typical *ix places.

Got it. *sort of*. Looking a bit more, I see the following;
dmesg | grep -i eth0
[ 3.582327] e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection
[ 7.218819] udev: renamed network interface eth0 to eth3

same with eth1 (renaming to eth2)
So, I changed my interface file and all works well.

Not happy with an eth2/3, and would like to change it, but the box is up and responding now!
