To add newly assigned IP addresses from SSH, follow this procedure:
(Please follow the steps given below only on a Centos / Fedora.)
Login to your server with SSH as root.
Go to the /etc/sysconfig/network-scripts directory.
- cd /etc/sysconfig/network-scripts/
Verify which interface you will use to add IP addresses. Typically, this will be eth0 for public IP addresses.
- /sbin/ifconfig
Make a copy of ifcfg-eth0 for each IP you wish to add and name them as ifcfg-eth0:0, ifcfg-eth0:1 etc.
- cp ifcfg-eth0 ifcfg-eth0:0
- cp ifcfg-eth0 ifcfg-eth0:1
- cp ifcfg-eth0 ifcfg-eth0:2
- cp ifcfg-eth0 ifcfg-eth0:3
- cp ifcfg-eth0 ifcfg-eth0:4
Open each of them and change the fields DEVICE, .IPADDR and NETMASK accordingly.
Restart the network:
- /etc/init.d/network restart
