I run PPP to a static address provided by an ISP. Some of my buddies may
be having some fun with me; it'd be nice to catch them at it :)
Is there anything out there, in software, which can watch a PPP connection
and report on the source of the incoming packets? If so, what would that
be? Knowing the packet source, the source can be traced and dealt with.
Kernel is 1.2.13 (yeah, it's a bit old... but it works well!)
