check IP

what is the command to check my pc's ip address?

**spoon!** · 12-13-2005

Code:

ifconfig

look under "eth0" or whatever your network interface is called
then look for "inet addr"

Command not found

You can su to root before running it.

Or try

Code:

which ifconfig

and then type the full path as a normal user. (In my case it is /sbin/ifconfig.)

"which" is not going to find it if it's not in the PATH (which it obviously isn't). But yes it is usually at /sbin/ifconfig

Yeah, if you are using Fedora, you have to type the full path (or at least that was what it was like in Fedora Core 3).

ifconfig will only give the internal address, not the external address,

Code:

tux ~ # ifconfig
eth0      Link encap&#58;Ethernet  HWaddr 00&#58;0B&#58;CD&#58;85&#58;A5&#58;8A  
          inet addr&#58;192.168.0.2  Bcast&#58;192.168.0.255  Mask&#58;255.255.255.0

Is there anyway to find the external address? (I am connected via DHCP through a router)

it gives me the following error message

which: no ifconfig in (/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/usr/games:/usr/lib/java/bin:/usr/lib/java/jre/bin:.)

You can see that spoon already told you it wasn't going to work like that.

It will work if you do this.

Thanks Cabhan. I was just wondering if there was a way I could do it without using a website like this. Is there some way for me to interrogate the router for this information??
