How to setup CVS server side to support SSH authentication?

firedragon

I know that to Set up the server for password authentication, just
create a file called `/etc/xinetd.d/cvspserver' containing the following:

  service cvspserver
{
   port        = 2401
   socket_type = stream
   protocol    = tcp
   wait        = no
   user        = root
   passenv     = PATH
   server      = /usr/local/bin/cvs
   server_args = -f --allow-root=/usr/cvsroot pserver
}
Then /etc/init.d/xinetd restart

But I don't know how to setup CVS server side to support SSH authentication.
