I'd like to have a way of capturing all Internet packets, to try to
diagnose a communication problem that I can't reproduce in-house. I
tried having a user go to the terminal and say
sudo tcpdump -xX -i en0 -s 0 > ~/tcp.txt
but that didn't work, probably because en0 was not the right
interface. The tcpdump man page says
On Linux systems with 2.2 or later kernels, an
interface argument of ``any'' can be used to cap-
ture packets from all interfaces.
but unfortunately that doesn't work on the Mac. How do you even find
out what the legal choices for "-i" are?
