HOW DO I MANAGE IP ADDRESSES ON MY DEDICATED SERVER WITH FEDORA BASIC?

Answer by: George Kaloyanov, Aplus.Net Knowledge Base Support

Important: This article is applicable only for dedicated servers running on operating system Fedora basic (without Plesk control panel).

By default, each dedicated server plan with Aplus.Net is assigned with one IP Address. You can sign up for additional IP(s) during initial server setup or later. Once the particular IP(s) are disclosed to you, please follow the instructions below on how to add them to your dedicated server IP pool:

1. Login to your server using SSH with username root
2. Go to the network-scripts directory:
   # cd /etc/sysconfig/network-scripts/
3. You will find a file with name ifcfg-eth0. If you already have more than one IP address, then you may want to get a list of all IP configuration files:
   # ls ifcfg-*
   You can read these files in order to check which IPs are assigned inside:
   # less ifcfg-eth0
   Note: We assume assume that you have only one IP address on your dedicated server at the moment.
4. Make a copy of that file:
   # cp ifcfg-eth0 ifcfg-eth0:0
   Then open the copy with vi or other text editor:
   # vi ifcfg-eth0:0
5. Go to the line with DEVICE=… and change it to:
   DEVICE=eth0:0
6. Go to the line with IPADDR=… and change the IP address to the IP address that was assigned to your server by the Aplus.Net Network Administrators.
7. Make sure that the value of ONBOOT=… equals to yes.
8. If you wish to add more IPs to your dedicated server please repeat steps 4, 5, 6 and 7. The only difference is that the files should be named as ifcfg-eth0:1, ifcfg-eth0:2, ifcfg-eth0:3, etc.
   Note: Please make sure that you follow the naming convention ifcfg-eth0:#, where # is the file number.
9. Finally, run the command service network restart in order for the changes to take effect.
