[Cialug] RedHat ES 4 - static IP's?

[Dave J. Hala Jr.]

What seems wierd to me is that it boots with DHCP. That leads me to
believe there is a DHCP config somewhere or somehow it is a default.
Could it be that on boot, the init scripts look for an eth0 config and
when they don't find it, they default to dhcp?
 
If you do an "ifconfig", that will show you the config for all the
interfaces.
