netdiag?

[David N. Blank]

In my travels along the anonymolus ftp byways I encountered a file called
netdiag.tar.Z that had what appeared to be a really handy network
debug/display tool with some problems:

1) It was a set of Sun 3 binaries with no source code that ran only under
   Suntools.
2) The README file was truncated at 512 bytes, (in mid-sentence, even).
3) There were not docs external to the program.

Does anyone have any information on this program and where I could get a
more complete version of it?  Thanks muchly in advance.
