tcpdump is available in source from ftp.ee.lbl.gov by anonymous ftp,
but unless you have a Sun-3 with SunOS3.5 it is un-useable.  If you
have SunOS4.0 you will need to do two things:

 1) Install a kernel fix on Sun-3's (I think Sun-4's are okay).  
    The if_nit.o file is also at ftp.ee.lbl.gov.

 2) Modify the source to work with Sun's new STREAMS based NIT 
    interface.

So now, if you have done step one, I will gladly send you my diffs
since I have already done step two.  I cannot set up anonymous ftp
service, but I will mail my diffs until somebody is nice enough to
archive them...

More Notes...

 1) Sun's NIT interface cannot always report on its outgoing traffic,
    so don't think something is wrong if you don't see any.

 2) The clock resolution on Sun-3's is pretty lame... 1/50 of a
    second.  If you have dollars for a nice protocol analyzer,
    go for it!


Have Fun!
