remote cvs connection analasys (debug)

[Harry Putnam]

Setup: Redhat Linux 7.1
Cvs  : 1.11.1p1 (client/server)

Having trouble with a remote connection that has worked in the past.
The server moved and ever since I cannot connect to it.  I'm using the
right address far as I know and other people are successfully
connecting remotely to it.

I am able to connect remotely to other cvs servers.

I wondered if there is a way to force verbosity, where the negotiation
get printed to tty or something similar so that I can see what is the
problem.  The normal flags for that kind of stuff -[vV] are taken for
other things and I see no `debug' or `verbose' option in man cvs

A failed attempt looks like this:

 $ cvs -d :pserver:address@hidden:/usr/local/cvsroot login
Logging in to :pserver:address@hidden:2401/usr/local/cvsroot
CVS password: <password>
cvs [login aborted]: recv() from server cvs.gnus.org: Connection reset by peer

This looks like something unrelated to cvs but how can I get more info
on what is happening?
