It might. RH released an errata kernel yesterday. Have you tried it yet? I have heard of breakage on that card in some of the newer kernels. I don't know which versions though, I just remember it being in the pcnet32 driver. Some Google searches may be in order. If it persists after installing the latest kernel from RH (or if you've already installed it), I would put this in Bugzilla. > > > 2) When I use ssh from either RedHat machine, it always does a DNS > > > lookup on the machine name. > > <snip> > Good idea -- I should have thought of that myself:).

I think the problem is that IPv6 is enabled by default in the newer (since 7.2?) kernels. Since the kernel will run through IPv6 first and then fall back to IPv4, you would need to have IPv6 style hosts in the /etc/hosts file for it to respect that properly. But this is from memory, so there may be some innaccuracies. I would say to disable IPv6 if not needed or make sure you have IPv6 hosts in the /etc/hosts file. That should resolve the issues. <snip> Hope it helps. -- Brian Ashe CTO Dee-Web Software Services, LLC.
