Yes, I can both telnet to the port and connect via a cvs client to the server. Would you please check the content of my file to make sure it's ok, thanks:
$ cat /etc/xinetd.d/cvs
# default: off
# description: The CVS service can record the history of your source \
#              files. CVS stores all the versions of a file in a single \
#              file in a clever way that only stores the differences \
#              between versions.
service cvspserver
        disable = no
        port                    = 2401
        socket_type             = stream
        protocol                = tcp
        wait                    = no
        user                    = root
        passenv                 = PATH
        server                  = /usr/bin/cvs
        env                     = HOME=/cvs
        server_args             = -f --allow-root=/cvs pserver
#       bind                    =

2 questions:
1. is cvs is a reserved word or could I or should I call a repository cvs or can it be part of a path /repo/cvs/proj?
2. in server_args, is the placement of the -f parameter ok?

Good point, thanks.

Will do, thanks.
