Hi all,

I'm trying to set up a small cluster of FC3 machines to perform some protocol research. Each of the machines has three network cards, eth0, eth1 and eth2.

On every computer, eth0 is physically connected to a NAT router, and uses an assigned IP address (no DHCP). eth1 & eth2 are connected to isolated internal networks.

My issue:
On some computers, when I try and ping an outside IP address (accessible via the router), I have no issues. On others, however, ping tries to use eth1 or eth2, and of course can't find the address since these networks are isolated - I get a "Destination Host Unreachable" error. If I try to specify the interface using ping -I eth0, I get "Operation not permitted".

Basically, the big problem with this is that I'm trying to download code from an external CVS, and on the computers that can't ping the server, I can't connect to CVS either.

How do I specifiy which ethernet card to use as default? What am I missing here?

Thanks!

Oops, this should be in the networking forum. I'll re-post there.

At LQ it's customary to ask the moderators to move the thread. I have reported this thread to the moderators--I would expect them to close this thread.

If you want to move your thread to a different forum, don't double-post. Just report it to be moved. I'm closing this one, as the one in Networking has more answers: http://www.linuxquestions.org/questi...hreadid=351174
