RE: [Oscar-users] network problem with OSCAR4+FC2

Hi Shiang-Tai:   In the release notes it mentioned to boot your client node with the rescue CD so that you can acquire a 'correct' modprobe.conf for the client nodes (it is in /tmp/modprobe.conf on the rescued node).  This is essentially the same 'fix' that I mentioned.  However, if your server hardware is identical to your client nodes, then it is probably easier to follow my instructions especially if you do not have a CD-ROM drive on the nodes, etc.   Cheers,   Bernard From: Shiang-Tai Lin [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 04, 2005 17:09 To: Bernard Li Cc: oscar-users@lists.sourceforge.net Subject: Re: [Oscar-users] network problem with OSCAR4+FC2 Hi Bernard, Thanks a lot for your help. You are perfectly correct. Using the modprobe.conf from the sever node does solve the network problem. I had to make minor changes in the modprobe.conf file because the sever node has two network cards but the client has only one. [I did read the release notes about FC2. It suggested to boot the client with FC2 CD 1 and run the Rescue mode. I tried this method before posting my question but it didn't work.] This problem is now solved for me but I meet another problem related to pbs. I will send another message on this new problem. Thanks again.

On the server node, what module is loaded for the network card?

The server node has Fedora Core 2 installed. There is no problem building the client image and installing the image with a boot floppy disk (PXE doesn't work for me). However, after rebooting the client node, there appears to be no network connection available on the client. I cannot ssh to or from the client nodes. This seems to be the reason of failure later in step 5.11 "Complete the Cluster Setup". Is it possible to configure the network card on the client node? Or do I miss something important in the previous steps? (The only thing I know that I did not follow the instruction in the documentation is "Set the interface control protocol to none". I cannot find this option when running neat.) My network card, 82547GI Gigabit Ethernet, is correctly recognized in the server node. Thanks in advance for any hint.
