If you're looking to monitor traffic to localhost, bind the the `lo0` interface. For example, when I'm monitoring traffic to a local Rails app in development, I'll do something along the lines of:
sudo tcpflow -c -n lo0 src or dst post 3000
and it'll pick up the traffic.
(Thanks for the tips on alternative ways of monitoring TCP traffic flows, folks!)
Sounds like an awesome plan to me. I should be around at least 21st-28th, but I was kinda hoping to catch a football game (just because I've never seen a real one before) on the Sunday. Still, Tech Meetup would trump that if it did happen to clash.
