Okay, I found that ifconfig does not show the virtual IP address
Are you sure?
These are interface aliases, they should show up as a "different" interface such as eth0:0 or eth0:1. If you run "ifconfig" without any parameters, doesn't it show up?
with the IP stack in Linux as of kernel 2.4.something, and the 'ip' command, virtual addresses no longer need be associated with virtual interfaces like eth0:1, instead you can `ip addr add eth0 a.b.c.d`
the ifconfig command, written back in the stone ages, is blissfully unaware of this. it really should be deprecated in favor of `ip addr`
Where is the best documentation on how the ip capabilities map to the files in /etc/sysconfig/network-scripts? Do you have to use the eth0:n syntax there? Also, isn't there some way to describe up vlan trunks and subinterfaces there?
