Michael, Sorry, this is definitely off topic...

It's just not part of the OSCAR cluster. So, no need for gateway setup. And I am testing with the master node only at the moment. > you set up the head node as a gateway.

On this one, nodes can access internet via NAT/Masquerading. It's damn easy to setup, just fire the text version of network config and check proper boxes, then enable IP-forwarding on master node. I don't know why RedHat/Fedora guys had this option hidden in the usual GUI setup utility. Of course, you can still set it up manually if you prefer... > Here is a howto which I have used to set up my dual nic head node to > act as a gateway to the outside network. > > http://tldp.org/HOWTO/IP-Masquerade-HOWTO/ > > I think the head node should be able to mount the files, but I am not > certain it will work neccesarily without the gateway setup either. Googled for ages still to no avail. That's a mistery. I can ping, ssh and even smbclient to the fileserver from the master node but still no write access to NFS mounts. Checked uids/guids matching and everything else I can think of. Looks like another Fedora 7 bug, something to do with the old and trusty portmap being replaced by rpcbind (which is a NetBSD port I guess). --Ivan ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
