36: <b>CVSync</b> is a software package for distributing and updating source
37: 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
38: sources are maintained in a CVS repository on a central development machine
39: in Canada. With CVSync, OpenBSD users can easily keep their own source trees
1.10 naddy 40: up to date.
1.1 espie 41: </p>
42:
43: <p>
44: <b>CVSync</b> uses the so-called pull model of updating. Under the pull
45: model, each client asks the server for updates, if and when they are
46: wanted. The server waits passively for update requests from its clients.
47: Thus all updates are instigated by the client. The server never sends
48: unsolicited updates. Users must either run the <b>CVSync</b> client
49: 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 50: automatically on a regular basis.
1.1 espie 51: </p>
52:
53: <p>
54: The term <b>CVSync</b>, capitalized just so, refers to the entire software
55: package. Its main components are the client <tt>cvsync</tt> which runs on
56: each user's machine, and the server <tt>cvsyncd</tt> which runs at each of
1.10 naddy 57: the OpenBSD CVSync mirror sites.
1.1 espie 58: </p>
59:
60: <p>
61: <b>CVSync</b> is intended to be both faster and flexible than
1.7 naddy 62: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sup&sektion=1&format=html">sup(1)</a> and CVSup.

66: The OpenBSD Project currently has five main source repositories:
67: </p>
68:
69: <ul>
70: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.</li>
71: <li><b>ports</b> - Houses the <a href="./ports.html">OpenBSD Ports</a>.</li>
1.10 naddy 72: <li><b>www</b> - Houses all OpenBSD web pages (including this one).</li>
1.1 espie 73: <li><b>x11</b> - Houses OpenBSD's adaptation of the
74: <a href="http://www.XFree86.org/">XFree86-3</a> software project.</li>
75: <li><b>xf4</b> - Houses OpenBSD's adaptation of the
76: <a href="http://www.XFree86.org/">XFree86-4</a> software project.</li>
77: </ul>

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

92: </h3>
93:
94: <p>
95: If you only care about running CVSync, it is recommended that you
96: download the cvsync package from the <a href="ftp.html">ftp mirror
97: sites</a> instead of building your own from the <tt>net/cvsync</tt>
1.10 naddy 98: port.

101: <p>
102: For further information about CVSync, see the
103: <a href="http://www.cvsync.org/">project homepage</a>.
104: </p>
105:
106: <p>
107: In order to mirror the OpenBSD repository with CVSync,
108: the following configuration file might be used:
109: </p>
110:
111: <pre>
112: config {
113: hostname anoncvs.de.openbsd.org
1.5 naddy 114: # If your network link is a T1 or faster, comment out the following line.
1.1 espie 115: compress
1.4 espie 116: collection {
1.5 naddy 117: name openbsd release rcs
1.4 espie 118: prefix /cvs
1.5 naddy 119: umask 002
1.4 espie 120: }
1.1 espie 121: }
122: </pre>
123:
124: <p>
125: This directs cvsync to refresh all OpenBSD distributions from
126: <b>anoncvs.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
127: permission to the local repository.
128: </p>
129:
130: <p>
131: Assuming this file is saved as <tt>cvs-syncfile</tt>, the
132: following command would be used to invoke cvsync
133: </p>
134: <pre>
135: cvsync -c cvs-syncfile
136: </pre>

142: <p>
143: It is now simple to check out any one of the CVSync'ed repositories.
144: For Korn/Bourne shells:
145: </p>
146: <pre>
147: # cd /usr
148: # CVSROOT=/cvs cvs checkout src
149: </pre>
150: <p>
151: For csh and its derivatives:
152: </p>
153: <pre>
154: # cd /usr
155: # setenv CVSROOT /cvs
156: # cvs checkout src
157: </pre>
158:
159: <p>
160: The above will check out the most current sources. Many of you will only
161: want the release sources, especially if you are patching your system. To
162: checkout release sources you must specify a tag along with your command.
163: For example:
164: </p>
165: <pre>
166: # cd /usr
1.17 ! david 167: # cvs checkout -rOPENBSD_3_5 src
1.1 espie 168: </pre>
169: <p>
1.17 ! david 170: Or <tt>OPENBSD_3_4</tt> for 3.4, etc.

268: <strong>IMPORTANT NOTE:</strong>
269: There are a few issues relating to cryptographic software that everyone
270: should be aware of:
271: </p>
272: <ul>
273: <li>
274: <p>
275: The OpenBSD sources are from Canada. As
276: <a href="http://www.efc.ca/pages/doc/crypto-export.html">
277: researched by a Canadian individual</a> and as
278: <a href="http://axion.physics.ubc.ca/ECL.html">
279: described in the Export Control list of Canada</a>,
280: it is legal to export crypto software from Canada to the world.
281: </p>
282: </li>
283: <li>
284: <p>
285: However, if you are outside the USA or Canada, you should not
1.8 naddy 286: fetch the cryptographic sections of the OpenBSD sources from a
287: CVSync server located in the USA. The files in question are...
1.1 espie 288: </p>
289: <ul>
290: <li><tt>src/kerberosIV/*</tt></li>
291: <li><tt>src/kerberosV/*</tt></li>

300: <li><tt>XF4/xc/lib/Xdmcp/Wraphelp.c</tt></li>
301: </ul>
302: <p>
303: Because of the USA ITAR munitions list,
304: crypto software may only be exported to Canada from the USA.
305: </p>
306: </li>
307: </ul>
