37: <p>
38: <b>CVSync</b> is a software package for distributing and updating source
39: 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
40: sources are maintained in a CVS repository on a central development machine
41: in Canada. With CVSync, OpenBSD users can easily keep their own source trees
1.10 naddy 42: up to date.
1.1 espie 43: </p>
44:
45: <p>
46: <b>CVSync</b> uses the so-called pull model of updating. Under the pull
47: model, each client asks the server for updates, if and when they are
48: wanted. The server waits passively for update requests from its clients.
49: Thus all updates are instigated by the client. The server never sends
50: unsolicited updates. Users must either run the <b>CVSync</b> client
51: 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 52: automatically on a regular basis.
1.1 espie 53: </p>
54:
55: <p>
56: The term <b>CVSync</b>, capitalized just so, refers to the entire software
57: package. Its main components are the client <tt>cvsync</tt> which runs on
58: each user's machine, and the server <tt>cvsyncd</tt> which runs at each of
1.10 naddy 59: the OpenBSD CVSync mirror sites.

62: <p>
1.23 nick 63: <b>CVSync</b> is intended to be both faster and more flexible than

1.42 nick 68: The OpenBSD Project currently has six main source repositories:
1.1 espie 69: </p>
70:
71: <ul>
72: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.</li>
1.78 steven 73: <li><b>ports</b> - Houses the <a href="faq/ports/index.html">OpenBSD Ports</a>.</li>
1.10 naddy 74: <li><b>www</b> - Houses all OpenBSD web pages (including this one).</li>
1.26 matthieu 75: <li><b>X11</b> - Houses OpenBSD's adaptation of the
76: <a href="http://www.XFree86.org/">XFree86-3</a> software project.
1.51 deraadt 77: <li><b>XF4</b> - Houses OpenBSD's adaptation of the XFree86-4 source tree.
78: <li><b>xenocara</b> - Houses OpenBSD's active X.org v7 source tree.
1.1 espie 79: </ul>
80:
1.84 jasper 81: The <b>X11</b> and <b>XF4</b> repositories are here just for historical
1.97 tedu 82: purposes, most users will have no reason to use those trees, they are no longer
1.84 jasper 83: being used.

1.1 espie 85: <h3><a name="CVS"><font color="#0000e0">What Is CVS?</font></a></h3>
86:
87: <p>
88: CVS is the source code control system used to manage the OpenBSD source
89: tree. It is described in more detail <a href="anoncvs.html#CVS">here</a>.
90: Note that CVS and CVSync are entirely different programs. Although
91: CVS can be used for remote file access, it is not optimized for
92: wholesale source tree distribution over the net, and CVSync can be
93: easily an order of magnitude more efficient for this task.
94: </p>

96: <h3>
97: <a name="starting"><font color="#0000e0">Getting Started Using CVSync</font></a>
98: </h3>
99:
100: <p>
101: If you only care about running CVSync, it is recommended that you
102: download the cvsync package from the <a href="ftp.html">ftp mirror
103: sites</a> instead of building your own from the <tt>net/cvsync</tt>
1.10 naddy 104: port.
1.1 espie 105: </p>
106:
107: <p>
108: For further information about CVSync, see the
109: <a href="http://www.cvsync.org/">project homepage</a>.
110: </p>
111:
112: <p>
113: In order to mirror the OpenBSD repository with CVSync,
114: the following configuration file might be used:
115: </p>
116:
117: <pre>
118: config {
1.103 ! mpi 119: hostname anoncvs.eu.openbsd.org
1.5 naddy 120: # If your network link is a T1 or faster, comment out the following line.
1.1 espie 121: compress
1.4 espie 122: collection {
1.5 naddy 123: name openbsd release rcs
1.4 espie 124: prefix /cvs
1.5 naddy 125: umask 002
1.4 espie 126: }
1.1 espie 127: }
128: </pre>
129:
130: <p>
131: This directs cvsync to refresh all OpenBSD distributions from
1.103 ! mpi 132: <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

264: <strong>IMPORTANT NOTE:</strong>
265: There are a few issues relating to cryptographic software that everyone

267: </p>
268: <ul>
269: <li>
270: <p>
271: The OpenBSD sources are from Canada. As
272: <a href="http://www.efc.ca/pages/doc/crypto-export.html">
273: researched by a Canadian individual</a> and as
274: <a href="http://axion.physics.ubc.ca/ECL.html">
275: described in the Export Control list of Canada</a>,
276: it is legal to export crypto software from Canada to the world.
277: </p>
278: </li>
279: <li>
280: <p>
281: However, if you are outside the USA or Canada, you should not
1.8 naddy 282: fetch the cryptographic sections of the OpenBSD sources from a
