Struggling a bit trying to work this out. I'm on a Centos 5.5 VPS with multiple IP addresses.
I've setup the IP address alias for eth0 (eth0, eth0:1, eth0:2, eth0:3, eth0:4, eth0:5), each with a different static address, using the Red Hat Text Mode Setup Utility (setup).
I've saved the config and rebooted but only eth0 and eth0:5 show up with ifconfig.
The folder /etc/sysconfig/networking/devices shows all interfaces scripts
but /etc/sysconfig/network-scripts/ only has ifcfg-eth0 and ifcfg-eth0:5 (which is what ifconfig seems to find).
Do I need to do anything else to make those aliases show up?
