<DIV><FONT face="Courier New">You will need some heuristics to do that. If what
you are interested in is IP traffic, I would probably list the adapters with
their associated IP addresses. In the simple case (a machine with just one wired
or wireless connection), you will get two (or three) adapters and only one of
them will have a (valid) IP address associated to the adapter. And you will pick
that one.</FONT></DIV>
<DIV><FONT face="Courier New">Things get much more complicated if</FONT></DIV>
<DIV><FONT face="Courier New">1. the machine has more than one
adapter</FONT></DIV>
<DIV><FONT face="Courier New">2. (a special case of 1.) the machine has a wired
and a wireless adapter (all the modern laptops have both), and the user switches
often between the adapters (or use both of them at the same time). In this case
you will need to capture from both the adapters.</FONT></DIV>
