How to add IP addresses ?
To add new IP addresses to network interface in FreeBSD you need to manually edit /etc/sysconfig file. Just add one line per IP. Format of the file is self-explanatory. To see the current network interface configuration use: ifconfig -a. To add IPs in LINUX you need to create a new file per each IP in /etc/sysconfig/network-scripts directory. You will find in this directory file with a name ‘ifcfg-eth0’ or very similar. Open it in editor, you will easily recognize the first ip of your computer and figure out file format. Now copy this file: $cp ifcfg-eth0 ifcfg-eth0:0 Now edit a new file: you need to change original ip to a second one. Save edited file. To add a third ip: $cp ifcfg-eth0 ifcfg-eth0:1 Again edit it to change the first ip to a third one.
