Hi,
On one of our systems we have the following network adapters :

The question I have is regarding eth0:1 and eth0:2. I can't see where they
are defined ...
[root at optest01 networking]# cd /etc/sysconfig/networking/devices/
[root at optest01 devices]# ls -la
total 40
drwxr-xr-x 2 root root 4096 Nov 21 10:25 .
drwxr-xr-x 4 root root 4096 Sep 25 09:18 ..
-rw-r--r-- 3 root root 277 Dec 18 16:57 ifcfg-eth0
-rw-r--r-- 3 root root 222 Dec 18 16:57 ifcfg-eth1
-rw-r--r-- 3 root root 175 Dec 18 16:57 ifcfg-eth2
Not there?? If I start up system-config-network, it doesn't show them. Can
someone give me a clue as to where they might be hiding?
Thanks,
Steve
