If you just mean a PC running a sniffer application, it's pretty unlikely you'll be able to do any WAN analysis. The biggest problem is that PCs don't have much in the way of interfaces that can be put in a monitor position (ever seen a laptop with a T1 or T3 interface?). There are some RS-422 PCMCIA cards out there that are capable of, say, HDLC decode. However, I haven't been able to find any sniffer package that will interface to the driver code for those PCMCIA cards. If I knew more than just elementary C++, maybe I could write the code to make the interface between the two. I did some research a while back but it wasn't promising. I'm hopeful that after I get a little more familiar with Linux some new doors might open. Likely, you'll need a WAN analyzer. They typically run in the $10k(US) to $25k range. Not your typical home lab toy.
