EtherWatch is a tool for observing raw ethernet traffic on a research Ethernet. It is especially useful for debugging very low level communications problems.

It will work with either a 3MB net or a 10MB net. By default, it looks at the first Ethernet board connected to your machine. If you have more than one, you can use the Interpreter to adjust EtherWatch.network. EtherWatch.network.next is the second Ethernet board. The next time you Poke NewHost, EtherWatch will notice that things have changed.

The host number filtering hasn't been debugged.

There are a handful of switches to select which types of packets get printed. Feel free to add another if you need it.

EtherWatch was cloned from PupWatch. It has the same general crufty structure. If you want another instance you have to run it again, and chew up another GFI. You can have several instances active at the same time.
