Running the following command using the CVSNT version of "cvs" hangs:
"C:\Documents and Settings\matseitz>cvs -d anonymous at cvs.openssl.org:/openssl-cvs
rlog openssl/LICENSE"
When I eventually press Ctrl-C, I see the following error:
"cvs [rlog aborted]: received interrupt signal"
Here's the CVSNT version I am running:
"C:\Documents and Settings\matseitz>cvs --version
Concurrent Versions System (CVSNT) 2.5.03 (Scorpio) Build 2382 (client/server)"
The Cygwin version of "cvs" works fine.
"$ cvs --version
Concurrent Versions System (CVS) 1.11.22 (client/server)"
Running CVSNT "cvs" with debug tracing on gives:
"C:\Documents and Settings\matseitz>cvs -t -t -t -d anonymous at cvs.openssl.org:/op
enssl-cvs rlog openssl/LICENSE

I've also taken network traces, and it appears the CVSNT version hangs right after receiving a reply to an SSH "Diffie-Hellman Key Exchange Init" request (see frames 9-10 below). My client sends a TCP ACK, but there is no further traffic, until 17 seconds later when the client closes the TCP connection.
Here'a summary of the network trace:
