Hello,

I need to bind 2 ips to the server(they are in my given ip ranged but haven't been bound to the server). Any idea how I can do this?

Thanks

You can set both addresses on the same network card. One will be assigned to the card itself, the other will be an alias to the card.

Primary address: ifconfig eth0 1.2.3.4 netmask 255.255.255.0
Second address: ifconfig eth0:1 1.2.3.5 netmask 255.2555.255.0

There is still some thingss that aren't known. Is this behind a firewall? Are addresses being natted? Is this for a server on the internet or on your intranet?

All of these make a difference in how things are set up.

The above means of binding IP addresses to a single NIC are good with a few exceptions. eth0:0 is the first usable one.

The second point is that those created IP addresses are only good untilo you reboot.

If you are using redhat, create separate files for
/etc/sysconfig/network-scripts/ifcfg-eth0 ifcfg-eth0:0 and ifcfg-eth0:1 etc

If you are using debian based, then the file to edit is /etc/network/interfaces
