Hello,
I've got a very unusual network interface issue on centos5. I'm setting
up a router box, with two network interface cards, the first gets it's
information from a dhcp server, the second is statically configured. I have
no idea what happened, but yesterday the internal interface eth1 stopped
showing up. An ifconfig eth1 showed the interface not found, but an
ifconfig -a shows a strange __tmp interface. Below is some output:

If i reboot the box that tmp long number changes, that made me think that
the eth1 file was in the middle of an editing session when a crash occurred,
i however can not find a tmp file for a crashed editor session. I've tried
removing the nic and putting it in another box, and it worked. I am open to
suggestions.
Thanks.
Dave.
