Hello everybody!
Could anybody advice on the following problem. I need to assign several ip-addresses to 'lo' interface (beside 127.0.0.1). It is convenient to me to implement NAT with such addresses. I can easily assign these addresses on running system with 'ip address add <some addr/prefix> dev lo'. Yet I cannot understand how to make these settings apply on boot time. Certainly it is possible to patch standard system scripts like /etc/rc.d/init.d/network, but I suppose there must be more straight way to do this.
This is well enough explained in /usr/share/doc/initscripts-8.45.19.EL/sysconfig.txt
In /etc/sysconfig/network-scripts you need to create a file: ifcfg-l0:1 where all you really need is the ipaddr and netmask values.
