Hello.
I use Debian Jessie and I want to know how can I add another IP addresses to my NIC for support other networks?

Tnx.

While I don't know Debian, this works on any relatively new Linux platform:

Code:

ip addr add 192.168.1.123/24 dev eth0

When you are tired of the IP address, you can remove it as well:

Code:

ip addr del 192.168.1.123/24 dev eth0

To list all your ip addresses:

Code:

ip a

or

Code:

ip a s dev eth0

I love the succinctness of these command.

Don't forget the CIDR prefix (why is it called prefix if it's at the end?) /24 or whatever is correct in your environment. It will be used to build a matching routing table entry; if you leave it out, /32 is assumed.
