Using Mac OS X's Terminal application, I want to use netstat to display a real-time, continuous listing of my internet connections.

For example, with Terminal open and the proper netstat command in use, each time I browse to a website, display the source and destination IP addresses and ports.

netstat -w 3 displays real-time packet and byte info. I figured netstat -w 3 -p tcp would show actual source and destination addresses, but it does not.

Any suggestions? Thank you!

Sounds like you either want "tcpdump -p tcp" or "watch 'netstat -p tcp'" depending on which output you're interested in.

Can you elaborate a bit on tcpdump -p tcp? Cheers. –  tjt263 Sep 25 at 1:33
Oh, & watch too.. –  tjt263 Sep 25 at 1:34
tcpdump -p tcp simply shows you all the tcp packets going through your default network interface, and watch runs a command repeatedly showing you the output as it changes. –  mikebabcock Sep 28 at 2:00
