I'm running RedHat 6.0 on a laptop and would like to have the flexibility
of plugging into different ethernet ports (using different IP address, of
course). Now, when I configured the laptop, I configured it using a
static IP address (it wouldn't accept the bootp, etc options), and I'm not
able to re-configure it to work off of another IP address.
I've tried using the Control Panel->Networking applet to re-configure the
system to another IP address, gateway, etc. I've also modified, manually,
/etc/hosts ; /etc/sysconfig/network ; and
/etc/sysconfig/network-scripts/ifcfg-eth0 with a reboot. When I try
re-configuring the files, at rebooting gets stuck on the initiation of
sendmail (until I pop out the ethernet PCMCIA card and hit <ctrl>-c).
Any suggestions on how I can configure the machine "dynamically"? Thanks
