ifconfig

[labbe5]

type in terminal :

ifconfig, and some information will be available about your network.

If your are behind a firewall or proxy, a private ip is assigned to you which will start with 10, 172 or 192.

It is a way to check if your firewall or proxy setup works as expected.

UPDATE :
ip address as an alternative.

I seem to have several IP addresses, depending on what tool I ask. How do I tell which IP address to use when setting up P2P VOIP?

If you use ifconfig, it may indicate local loopback interface lo as 127.0.0.1, ignore that one.

If you are connected by ethernet then it may be something like eth0 (or new naming scheme starts 'en') and use the address given there (e.g. on my network it is 192.168.1.10 but that's just an example).

If you are connected by wifi, might be interface wlan0 (or something else starting with wl for wireless lan), so you would use the IP address supplied for that.

Some detail about how interfaces might be named (including recent changes to the naming scheme) can be found here:

For your external ip you can always query http://icanhazip.com/ like puppy does.

But some people don't like that....

If one doesn't like icanhazip, one can always try http://ipinfodb.com/
