CVS login FAQ: How do I login to a CVS server using SSH?
cvs login - a Windows example
Here's how I do a "cvs login" to our CVS server using SSH, on a Windows PC:
set CVSROOT=:ssh:al@some.server.com:/home/cvs/ cvs login
Note that the only real different thing here is that you specify the ssh protocol for communicating with the server.
