If you do not have pserver running, then checking to see if it will
respond seems rather pointless.

If you use the -t switch

   cvs -t -d :ext:address@hidden:/path/to/repository checkout foo

you will see it is trying to do (if you are not 100% certain that it is
running ssh, using the -t switch will help you determine if that is what
is happening or not):

   ${CVS_RSH:-rsh} -l username xxx.xxx.xxx.xxx cvs server

with the ${CVS_RSH} expanded to either the default "rsh" or to the
exported value of the variable ("ssh" in your case right?).

cvs expects that the Remote Shell transport will be eight-bit clean and
will not inject any extraneous text into the transfer by your shell init
file running 'fortune' or 'stty' or something like that.

        Enjoy!
