eth without IP, on purpose

trav.emme · 12-13-2009, 06:08 PM

While installing redhat I tried to turn off dhcp for eth1, but it then requires a static IP.

How do I configure eth1 and eth2 to be on but NOT acquire and IP address.
Some software I'm writing a paper on needs this to capture network traffic and analyze it.

Currently the logs indicate it wont use eth1 and eth2 because they have an IP address.

Thanks!

you could have them off and turn them up manually when you want to use them

ifconfig eth1 up
