What does it do?
If you have ever used the "Net Traffic" tool in Interarchy, you will have some idea of what Traffic Watcher does. Basically, it intercepts any network traffic coming in or going out of your computer and allows you to see it in a plain and simple format.
How does it work?
Traffic Watcher uses a tool called "tcpflow" that was originally adapted by Jeremy Elson from the well-known UNIX tool "tcpdump". Thankfully Marc Liyanage managed to port it to OS X!
How do I use it?
Note: The first time you use Traceroute, Traffic Watcher or Packet Watcher, you will be asked to Authenticate. This is separate from the “Edit > Authorize” system; it is required only once for these tools – and it will do all three at once.
In Traffic Watcher, you have to choose the Network Interface
you want to monitor. You do this by selecting one from the "Interface"
popup menu. Net Tool Box assumes that "en0" is the Ethernet
Interface, "en1" is the Airport Interface and "lo0"
is the Loopback Interface (virtual). If you use IP over FireWire (which
uses en1 also), you will need to specify this in the Net Tool Box preferences
