Cloning a Suse 10 Partition & Ethernet problems
Hi! I'm trying to clone a Suse 10 partition to various nodes in a cluster, but I have a problem with the network interfaces. The installation I need to clone has one eth interface, which gets the ip by dhcp. The original node works great, but when I try to boot the cloned nodes, they seem to look for the original eth interface, with a specific MAC. Does any body know if SuSe links each interface configuration with it's MAC, o something like that? Or what's the problem? Thanks in advance, Ignacio.

Yes, it does. Look at /etc/sysconfig/network. You'll see there that the script files which bring up/down interfaces are tied to the mac address. so, most probably you'll need to reconfigure the network cards on every node. Cheers -- -- Svetoslav Milenov (Sunny)
Really?? You mean I will have to reconfigure each node by hand? that's a pain! I hope any other alternative exists... Thanks any way Sunny, I'll continue looking for info, and please, if any one knows about this, will be appreciated :) Sunny wrote:

There are two different forms that both work for the files in /etc/sysconfig/network One is ifcfg-eth-XX-XX-XX-XX-XX-XX -- that is, a config by MAC address. The other is ifcfg-eth0, ifcfg-eth1, and so on. You should be able to move the config from ifcfg-eth-XX... To ifcfg-eth0, and go from there. (Note: I'm not sure whether YaST's management of the network cards breaks by doing this; I manage my network interfaces by hand, precisely because of the situation noted by the OP.)
Thanks! I'll try that tomorrow I post the results. I hope that works! Regards, Ignacio.

If you have two of the same NIC in the system, this will be a problem (opens the door to the random reassignment of eth0/1) otherwise it should be ok. Mike- -- Mornings: Evolution in action.
