In /etc/sysconfig/network-scripts there should be a file called something like ifcfg-eth0:0 for each IP address on that network card (eth0). The 0 and the end could be a 1,2,3,4,5 etc. There needs to be a separate file for each IP. If there isn’t, then duplicate ifcfg-eth0:0 as ifcfg-eth0:1 (or higher number if there’s already a ifcfg-eth0:1) and change the ip address in there to your new one.
Then execute: service network restart
Så skapa filer som heter ”ifcfg-eth0:1”, ”ifcfg-eth0:2” osv…
Kopiera innehållet i ifcfg-eth0 och ändra IP och eth0-saken till eth0:1 osv.
