You can use two separate TCP connections by putting "-P -" on the
command line, and compression is easily disabled with "-Z". The
protocol is plain text, so with those two options it's easy to follow
it using either tcpdump or ktrace.
In this case it really sounds like either a bona fide network problem
or some problem on the server side. (On the other hand, Grover
reported that it works OK under FreeBSD 4.x.) Just for fun, it would
be worthwhile to try forcing a lower MTU on the relevant network
interface or route.
