I just got my copy of Inter*Poll. Playing around I noticed that if
I ask for unnamed objects, I get something without a name on socket 4 of
virtually everything on the net. Here's the output (slightly reformatted
to make it more readable).

Laser{9,11} are invocations of lwsrv running on the same machine.
The last two entries are a kbox running KIP. The question is, what are
these mystery socket 4 things?
BTW, if you have an AppleTalk network and don't have Inter*Poll,
you should get yourself a copy. It's a really nice way to see what's going
on around your net. The only stupid thing about it is the name.

According to Inside AppleTalk, socket 4 is the Echo Socket...
The assigned sockets are as follows:

Socket 4 is used to support the Echo Protocol. It simply listens for packets and echoes them back to their sender. This can be used to determine if a particular node is alive, and also to find out how long it takes to reach that node. Echo Protocol is mentioned briefly in Inside Mac V-522 and described in more detail in Inside AppleTalk. -- UUCP: {ames,apple,portal,sun,voder}!claris!skip Applelink: SCHIPPER1 Internet: claris!skip@ames.arc.nasa.gov Phone: 415-960-2618
