 copy of the repository.  
   
 <p>  
 If you would like to operate a local anoncvs server, use cvs(1) commands  
 offline, or simply have faster access, you may use CVSync or rsync to  
 fetch a local copy of the repository.  
   
 <h3 id="CVSync">What Is CVSync?</h3>  
   
 <b>CVSync</b> is a software package specifically used for distributing  
 and updating <a href="https://man.openbsd.org/cvs">cvs(1)</a> repositories.  
 As it has knowledge of the file format it can operate more efficiently  
 than a general-purpose file synchronization program, however it is not  
 bug-free and can have problems updating at times.  
   
 <p>  
 The client <code>cvsync</code> runs on each user's machine (typically from  
 a <a href="https://man.openbsd.org/cron">cron(8)</a> job), and fetches  
 from a server running <code>cvsyncd</code>.  
   
 <h3 id="starting">Getting Started Using CVSync</h3>  
   
 <p>  
 CVS is part of OpenBSD's base system.  
 CVSync is an entirely different program and can be installed from  
 packages:  
   
 <pre class="cmdbox">  
 # <b>pkg_add cvsync</b>  
 </pre>  
   
 <p>  
 Do not build your own copy from unmodified upstream source -  
 the port/package has been modified to support commitid which is now  
 used in the OpenBSD repository.  
   
 <p>  
 In order to mirror the OpenBSD repository with CVSync,  
 the following configuration file might be used:  
   
 <pre class="cmdbox">  
 config {  
     hostname anoncvs.eu.openbsd.org  
     # If your network link is a T1 or faster, comment out the following line.  
     compress  
     collection {  
         name openbsd release rcs  
         prefix /cvs  
         umask 002  
     }  
 }  
 </pre>  
   
 <p>  
 This directs cvsync to fetch or refresh all OpenBSD distributions from  
 <b>anoncvs.eu.openbsd.org</b> with a  
 <a href="https://man.openbsd.org/umask">umask(2)</a> that permits group write  
 permission to the local repository.  
 The local copy of the files are stored in <code>/cvs</code>.  
   
 <p>  
 Assuming this file is saved as <code>cvs-syncfile</code>, the  
 following command would be used to invoke cvsync  
   
 <pre class="cmdbox">  
 $ <b>cvsync -c cvs-syncfile</b>  
 </pre>  
   
 <h3 id="rsync">Getting Started Using Rsync</h3>  
   
 <p>  
 Some repository mirrors offer access via rsync, a general-purpose  
 file synchronization program.  
 Again this should be installed from packages.  
 Two flavours are available:  
   
 <pre class="cmdbox">  
 # <b>pkg_add rsync</b>  
 Ambiguous: choose package for rsync  
 a       0: &lt;None>  
         1: rsync-3.1.2p0  
         2: rsync-3.1.2p0-iconv  
 Your choice:  
 </pre>  
   
 <p>  
 Unless you have other requirements, simply install the standard version  
 (option 1 on the list above).  
 You can select the flavour on the command-line to avoid  
 <a href="//man.openbsd.org/pkg_add">pkg_add(1)</a> prompting for the  
 version like so:  
 <pre class="cmdbox">  
 # <b>pkg_add rsync--</b>  
 </pre>  
   
 <p>  
 In order to mirror the OpenBSD repository with rsync,  
 the following command line might be used:  
   
 <pre class="cmdbox">  
 $ <b>rsync -avz --delete rsync://obsdacvs.cs.toronto.edu/obsdcvs/ /cvs/</b>  
 </pre>  
   
 <h3 id="using">Using CVS to Work With Your Repository</h3>  
   
 <p>  
 Now that you have a local copy of the CVS repository, it is now simple  
 to check out, update, or do any of the other CVS operations you would  
 normally do against a remote repository, locally.  
 For example:  
 <pre class="cmdbox">  
 $ <b>cvs -d/cvs checkout -P src</b>  
 $ <b>cvs -d/cvs up -Pd</b>  
 $ <b>cvs -d/cvs diff -u file.c</b>  
 </pre>  
 <p>  
 More details on CVS operation can be found in  
 <a href="faq/faq5.html#BldGetSrc">FAQ5, Fetching appropriate source  
 code</a> and in the  
 <a href="https://man.openbsd.org/cvs">cvs(1)</a>  
 man page.

 As of December 2017, the CVS repository sizes are:  
   
 <table>  
 <tr>  
     <td><strong>openbsd-ports</strong></td>  
     <td>- <b>1220</b>MB</td></tr>  
 <tr>  
     <td><strong>openbsd-src</strong></td>  
     <td>- <b>2865</b>MB</td></tr>  
 <tr>  
     <td><strong>openbsd-www</strong></td>  
     <td>- <b>704</b>MB</td></tr>  
 <tr>  
     <td><strong>openbsd-xenocara</strong></td>  
     <td>- <b>1658</b>MB</td></tr>  
 <tr>  
     <td><strong>openbsd-cvsroot</strong></td>  
     <td>- <b>158</b>MB</td></tr>  
 </table>  
   
 <p>  
 The overall repository size currently increases at a rate  
 of about <b>400</b>MB per annum. The src repository increases by about  
 <b>150</b>MB.  
   
 <p>  
 <strong>IMPORTANT NOTE:</strong>  
 There are a few issues relating to cryptographic software that everyone  
 should be aware of:  
   
 <ul>  
   <li>  
     <p>  
     The OpenBSD sources are from Canada. As  
     <a href="http://www.efc.ca/pages/doc/crypto-export.html">  
     researched by a Canadian individual</a> and as  
     <a href="http://axion.physics.ubc.ca/ECL.html">  
     described in the Export Control list of Canada</a>,  
     it is legal to export crypto software from Canada to the world.  
   <li>  
     <p>  
     However, if you are outside the USA or Canada, you should not  
     fetch the cryptographic sections of the OpenBSD sources from a  
     CVSync server located in the USA. The files in question are...  
     <ul>  
       <li><code>src/kerberosIV/*</code>  
       <li><code>src/kerberosV/*</code>  
       <li><code>src/lib/libdes/*</code>  
       <li><code>src/lib/libc/crypt/crypt.c</code>  
       <li><code>src/lib/libc/crypt/morecrypt.c</code>  
       <li><code>src/sys/crypto</code>  
       <li><code>src/sys/netinet</code>  
       <li><code>src/usr.sbin/afs/src/rxkad/*</code>  
     </ul>  
     <p>  
     Because of the USA ITAR munitions list,  
     crypto software may only be exported to Canada from the USA.  
 </ul>
