Re: How to know which Nic is eth0,1 or 2 ?

Hi Matt,

  I just tried this again and it doesn't seem to work for me. Sometimes
but not always I get into a very funky state ad the interfaces refuse to
come up. I stuck -vx in ifup to get a trace of what was happening and
have included an excerpt below. Maybe its a bug in RHEL, the only funny
thing I'm doing is setting up bonding but I can't imagine why that would
be a problem...... Any ideas?

Thanks,
Greg
