[K12OSN] Reading TCP packets

[Rob Owens]

How about putting a hub (not a switch) in between the remote device and 
the host in question.  Then you can hook up another computer to that hub 
and use wireshark or something similar.  The hub will cause all traffic 
to be broadcast to all ports on the hub so you'll be able to see it all 
with wireshark.

Or maybe just run wireshark on the host in question, and omit the hub.
