Re: Problems getting 2 NICs to work.

Below are the contents of the config files. And as for how it's 
working... my guess is that it's working because I'm running both of 
those class C's out of the same ethernet interface on the same router. 
All of the switches on my public network share the traffic of both 
ranges. Therefor that same eth port on the linux box is plugged in to a 
switch that has direct access to both ranges.


[root dtweb02 network-scripts]# cat ifcfg-eth0
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
ONBOOT=yes
USERCTL=no
PEERDNS=no
TYPE=Ethernet
IPADDR=12.168.88.12
DEVICE=eth0
HWADDR=00:0E:7F:37:5B:53
BOOTPROTO=none
NETMASK=255.255.255.0

[root dtweb02 network-scripts]# cat ifcfg-eth01
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
ONBOOT=yes
USERCTL=no
PEERDNS=no
TYPE=Ethernet
IPADDR=204.117.218.12
DEVICE=eth0
HWADDR=00:0C:72:30:52:53
BOOTPROTO=none
NETMASK=255.255.255.0
