Before you can use trpt on the Sun, you have to add
the line:

	options TCPDEBUG

to your kernal's config file and rebuild the kernal.

This isn't needed in 4.3BSD (or non-Sun 4.2BSD).  But
for some reason SMI decided to ifdef the trpt support
code in the kernal.

You do need the Sun sources, as Sun does NOT supply the
source to netinet/tcp_debug.c as part of their normal
distribution.  Worse, the supplied binary is compiled
without the trpt support.

Those people who want to use trpt on a Sun and don't have
sources should complain to SMI.  [I did once and they sent
me a tcp_debug.o that had been compiled properly.]

This info is for Sun OS's up to 3.2.  I gather that version
3.4 has a lot of 4.3's TCP support in it; perhaps they've
changed their tcp_debug module too.

Of course, you also have to turn on the debug option of
the sockets you want to trace, but that's standard BSD
and well documented.
