26: <b>CVSync</b> is a software package for distributing and updating source
27: trees from a master <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1">cvs(1)</a> repository on a remote server host. The OpenBSD
28: sources are maintained in a CVS repository on a central development machine
29: in Canada. With CVSync, OpenBSD users can easily keep their own source trees
1.10 naddy 30: up to date.
1.1 espie 31: </p>
32:
33: <p>
34: <b>CVSync</b> uses the so-called pull model of updating. Under the pull
35: model, each client asks the server for updates, if and when they are
36: wanted. The server waits passively for update requests from its clients.
37: Thus all updates are instigated by the client. The server never sends
38: unsolicited updates. Users must either run the <b>CVSync</b> client
39: manually to get an update, or they must set up a <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cron&sektion=8">cron(8)</a> job to run it
1.10 naddy 40: automatically on a regular basis.
1.1 espie 41: </p>
42:
43: <p>
44: The term <b>CVSync</b>, capitalized just so, refers to the entire software
45: package. Its main components are the client <tt>cvsync</tt> which runs on
46: each user's machine, and the server <tt>cvsyncd</tt> which runs at each of
1.10 naddy 47: the OpenBSD CVSync mirror sites.

1.42 nick 56: The OpenBSD Project currently has six main source repositories:
1.1 espie 57: </p>
58:
59: <ul>
60: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.</li>
1.78 steven 61: <li><b>ports</b> - Houses the <a href="faq/ports/index.html">OpenBSD Ports</a>.</li>
1.10 naddy 62: <li><b>www</b> - Houses all OpenBSD web pages (including this one).</li>
1.26 matthieu 63: <li><b>X11</b> - Houses OpenBSD's adaptation of the
64: <a href="http://www.XFree86.org/">XFree86-3</a> software project.
1.51 deraadt 65: <li><b>XF4</b> - Houses OpenBSD's adaptation of the XFree86-4 source tree.
66: <li><b>xenocara</b> - Houses OpenBSD's active X.org v7 source tree.
1.1 espie 67: </ul>
68:
1.84 jasper 69: The <b>X11</b> and <b>XF4</b> repositories are here just for historical
1.97 tedu 70: purposes, most users will have no reason to use those trees, they are no longer
1.84 jasper 71: being used.

1.1 espie 73: <h3><a name="CVS"><font color="#0000e0">What Is CVS?</font></a></h3>
74:
75: <p>
76: CVS is the source code control system used to manage the OpenBSD source
77: tree. It is described in more detail <a href="anoncvs.html#CVS">here</a>.
78: Note that CVS and CVSync are entirely different programs. Although
79: CVS can be used for remote file access, it is not optimized for
80: wholesale source tree distribution over the net, and CVSync can be
81: easily an order of magnitude more efficient for this task.
82: </p>

84: <h3>
85: <a name="starting"><font color="#0000e0">Getting Started Using CVSync</font></a>
86: </h3>
87:
88: <p>
89: If you only care about running CVSync, it is recommended that you
90: download the cvsync package from the <a href="ftp.html">ftp mirror
91: sites</a> instead of building your own from the <tt>net/cvsync</tt>
1.10 naddy 92: port.
1.1 espie 93: </p>
94:
95: <p>
96: For further information about CVSync, see the
97: <a href="http://www.cvsync.org/">project homepage</a>.
98: </p>
99:
100: <p>
101: In order to mirror the OpenBSD repository with CVSync,
102: the following configuration file might be used:
103: </p>
104:
105: <pre>
106: config {
1.103 mpi 107: hostname anoncvs.eu.openbsd.org
1.5 naddy 108: # If your network link is a T1 or faster, comment out the following line.
1.1 espie 109: compress
1.4 espie 110: collection {
1.5 naddy 111: name openbsd release rcs
1.4 espie 112: prefix /cvs
1.5 naddy 113: umask 002
1.4 espie 114: }
1.1 espie 115: }
116: </pre>
117:
118: <p>
119: This directs cvsync to refresh all OpenBSD distributions from
1.103 mpi 120: <b>anoncvs.eu.openbsd.org</b> with a <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=umask&sektion=2">umask(2)</a> that permits group write
1.1 espie 121: permission to the local repository.
122: </p>

124: <p>
125: Assuming this file is saved as <tt>cvs-syncfile</tt>, the
126: following command would be used to invoke cvsync
