32:
33: <p>
34: <b>CVSync</b> is a software package for distributing and updating source
35: 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
36: sources are maintained in a CVS repository on a central development machine
37: in Canada. With CVSync, OpenBSD users can easily keep their own source trees
38: up to date.
39: </p>
40:
41: <p>
42: <b>CVSync</b> uses the so-called pull model of updating. Under the pull
43: model, each client asks the server for updates, if and when they are
44: wanted. The server waits passively for update requests from its clients.
45: Thus all updates are instigated by the client. The server never sends
46: unsolicited updates. Users must either run the <b>CVSync</b> client
47: 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
48: automatically on a regular basis.
49: </p>
50:
51: <p>
52: The term <b>CVSync</b>, capitalized just so, refers to the entire software
53: package. Its main components are the client <tt>cvsync</tt> which runs on
54: each user's machine, and the server <tt>cvsyncd</tt> which runs at each of
55: the OpenBSD CVSync mirror sites.
56: </p>
57:
58: <p>
59: <b>CVSync</b> is intended to be both faster and flexible than
60: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sup&sektion=1&format=html">sup(1)</a>, and more flexible than CVSup.
61: </p>
62:
63: <p>
64: The OpenBSD Project currently has five main source repositories:
65: </p>
66:
67: <ul>
68: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.</li>
69: <li><b>ports</b> - Houses the <a href="./ports.html">OpenBSD Ports</a>.</li>
70: <li><b>www</b> - Houses all OpenBSD web pages. (Including this one).</li>
71: <li><b>x11</b> - Houses OpenBSD's adaptation of the
72: <a href="http://www.XFree86.org/">XFree86-3</a> software project.</li>
73: <li><b>xf4</b> - Houses OpenBSD's adaptation of the
74: <a href="http://www.XFree86.org/">XFree86-4</a> software project.</li>
75: </ul>
76:
77: <h3><a name="CVS"><font color="#0000e0">What Is CVS?</font></a></h3>
78:
79: <p>
80: CVS is the source code control system used to manage the OpenBSD source
81: tree. It is described in more detail <a href="anoncvs.html#CVS">here</a>.
82: Note that CVS and CVSync are entirely different programs. Although
83: CVS can be used for remote file access, it is not optimized for
84: wholesale source tree distribution over the net, and CVSync can be
85: easily an order of magnitude more efficient for this task.
86: </p>

88: <h3>
89: <a name="starting"><font color="#0000e0">Getting Started Using CVSync</font></a>
90: </h3>
91:
92: <p>
93: If you only care about running CVSync, it is recommended that you
94: download the cvsync package from the <a href="ftp.html">ftp mirror
95: sites</a> instead of building your own from the <tt>net/cvsync</tt>
96: port.
97: </p>
98:
99: <p>
100: For further information about CVSync, see the
101: <a href="http://www.cvsync.org/">project homepage</a>.
102: </p>
103:
104: <p>
105: In order to mirror the OpenBSD repository with CVSync,
106: the following configuration file might be used:
107: </p>
108:
109: <pre>
110: config {
111: hostname anoncvs.de.openbsd.org
1.5 ! naddy 112: # If your network link is a T1 or faster, comment out the following line.
1.1 espie 113: compress
1.4 espie 114: collection {
1.5 ! naddy 115: name openbsd release rcs
1.4 espie 116: prefix /cvs
1.5 ! naddy 117: umask 002
1.4 espie 118: }
1.1 espie 119: }
120: </pre>
121:
122: <p>
123: This directs cvsync to refresh all OpenBSD distributions from
124: <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
125: permission to the local repository.
126: </p>
127:
128: <p>
129: Assuming this file is saved as <tt>cvs-syncfile</tt>, the
130: following command would be used to invoke cvsync
131: </p>
132: <pre>
133: cvsync -c cvs-syncfile
134: </pre>
135:
136: <h3><a name="using">
137: <font color="#0000e0">Using CVS to Update Your Source Tree</font>
138: </a></h3>
139:
140: <p>
141: It is now simple to check out any one of the CVSync'ed repositories.
142: For Korn/Bourne shells:
143: </p>
144: <pre>
145: # cd /usr
146: # CVSROOT=/cvs cvs checkout src
147: </pre>
148: <p>
149: For csh and its derivatives:
150: </p>
151: <pre>
152: # cd /usr
153: # setenv CVSROOT /cvs
154: # cvs checkout src
155: </pre>
156:
157: <p>
158: The above will check out the most current sources. Many of you will only
159: want the release sources, especially if you are patching your system. To
160: checkout release sources you must specify a tag along with your command.
161: For example:
162: </p>
163: <pre>
164: # cd /usr
165: # cvs checkout -rOPENBSD_2_9 src
166: </pre>
167: <p>
168: Or <tt>OPENBSD_2_8</tt> for 2.8, etc.
169: </p>

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

296: <li><tt>XF4/xc-old/lib/Xdmcp/Wraphelp.c</tt></li>
297: <li><tt>XF4/xc/lib/Xdmcp/Wraphelp.c</tt></li>
298: </ul>
299: <p>
300: Because of the USA ITAR munitions list,
301: crypto software may only be exported to Canada from the USA.
302: </p>
303: </li>
304: </ul>
305:
306: <p>
307: The OpenBSD project is looking for more CVSync servers -- if you are
308: interested, please contact <a href="mailto:naddy@openbsd.org">Christian Weisgerber</a>
309: for configuration details.
