"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).

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??
