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.

1.23 nick 63: <b>CVSync</b> is intended to be both faster and more flexible than
64: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sup&sektion=1&format=html">sup(1)</a>
65: and <a href="cvsup.html">CVSup</a>.

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

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

96: <a name="starting"><font color="#0000e0">Getting Started Using CVSync</font></a>
97: </h3>
98:
99: <p>
100: If you only care about running CVSync, it is recommended that you
101: download the cvsync package from the <a href="ftp.html">ftp mirror
102: sites</a> instead of building your own from the <tt>net/cvsync</tt>
1.10 naddy 103: port.
1.1 espie 104: </p>
105:
106: <p>
107: For further information about CVSync, see the
108: <a href="http://www.cvsync.org/">project homepage</a>.
109: </p>
110:
111: <p>
112: In order to mirror the OpenBSD repository with CVSync,
113: the following configuration file might be used:
114: </p>
115:
116: <pre>
117: config {
1.40 grunk 118: hostname cvsync.de.openbsd.org
1.5 naddy 119: # If your network link is a T1 or faster, comment out the following line.
1.1 espie 120: compress
1.4 espie 121: collection {
1.5 naddy 122: name openbsd release rcs
1.4 espie 123: prefix /cvs
1.5 naddy 124: umask 002
1.4 espie 125: }
1.1 espie 126: }
127: </pre>
128:
129: <p>
130: This directs cvsync to refresh all OpenBSD distributions from
1.40 grunk 131: <b>cvsync.de.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 132: permission to the local repository.
133: </p>
134:
135: <p>
136: Assuming this file is saved as <tt>cvs-syncfile</tt>, the
137: following command would be used to invoke cvsync
138: </p>
139: <pre>
140: cvsync -c cvs-syncfile

149: to check out, update, or do any of the other CVS operations you would
150: normally do against a remote repository, locally.
1.50 nick 151: For example:

266: <strong>IMPORTANT NOTE:</strong>
267: There are a few issues relating to cryptographic software that everyone
268: should be aware of:
269: </p>
270: <ul>
271: <li>
272: <p>
273: The OpenBSD sources are from Canada. As
274: <a href="http://www.efc.ca/pages/doc/crypto-export.html">
275: researched by a Canadian individual</a> and as
276: <a href="http://axion.physics.ubc.ca/ECL.html">
277: described in the Export Control list of Canada</a>,
278: it is legal to export crypto software from Canada to the world.
279: </p>
280: </li>
281: <li>
282: <p>
283: However, if you are outside the USA or Canada, you should not
1.8 naddy 284: fetch the cryptographic sections of the OpenBSD sources from a
285: CVSync server located in the USA. The files in question are...
1.1 espie 286: </p>
