CVS in client/server configuration

[fahim . shafi]

We have been running CVS successfully in its default mode for some
time. I would now like to add the ability to connect to the repository
from a remote client . Here are my Q's:

1. Which is best and simplest way to go i.e.  rsh, authentication,
GSSAPI, kerberos?

2. How do I set-up the server? It is something like a deamon running
on repository machine?

3. Would I be able to use the 'normal' CVS concurrently with the
clent/server config.?

Thanks for all your help.
