31<title>Setting up a <acronym>CVS</acronym> server.</title>
32
33<para>A <acronym>CVS</acronym> server will be set up using OpenSSH
34as the remote access method. Other access methods, including :pserver: and
35:server: will not be used for write access to the <acronym>CVS</acronym>
36repository. The :pserver: method sends clear text passwords over the network
37and the :server: method is not supported in all <acronym>CVS</acronym> ports.
38Instructions for anonymous, read only <acronym>CVS</acronym> access using
39:pserver: can be found at the end of this section.</para>
