Search the info-cvs archives and you might have more luck. The short
answer is don't use it. Move along, this is not the protocol you are
looking for...

For HTML Cederqvist manual for cvs 1.12.11, look here:

For the client/server protocol, look here:

You should be able to find a doc/ file and a
doc/ -- these forms of the document describe both the
pserver framework and protocol (as well as the kserver and server
protocols). If you plan to read the document closely and you actually
care about security, issue ear-plugs to your neighbors so that your
screams will not distrub them too much.

In general, my personal opinion is that the pserver and kserver
protocols should be removed from the cvs sources completely. It is never
secure to run the cvs executable as root which is required to use the
pserver protocol. The cvs sources were never designed with security in
mind and running them as root is idiocy. (Just say no.)

You really want to consider moving to :ext: using the SSH transport.
This allows end-to-end security and does not provide as much room for
privilege escallation to arise.

If you feel you must use pserver and are not yet using it, you should
probably consider using some other source control system first.

If you are using pserver, I hope it is on an isolated LAN with lots of
firewalls and does not control any sources you really need to be kept
secure. I also hope that you are making plans to transition away from
pserver usage as fast as possible.

Summary: Friends don't let friends deploy cvs pserver configurations...
