When I execute tcpdump, I get the message:
tcpdump: /dev/bpf0: Permission denied
This makes it necessary to use sudo tcpdump for the command.
The same happens when I use libpcap to capture packets in my cocoa
application. How can I avoid this?

I discovered it was only capturing TCP packets, not UDP ones. The
tcpflow docs weren't very helpful since they seemed to hint at being
TCP only but had large portions copied almost verbatim from the
tcpdump docs, which discuss UDP as well.
I'm hacking together a protocol independent instant messaging and
presence framework (with a service provider interface for protocol
plug-ins -- I love NSBundle!) and this would be incredibly useful for
debugging purposes.
Has anyone made tcpflow show UDP packets, or found a similar utility
with that capability?
I believe snort can (www.snort.org). It compiles easily on OSX.
