+ <div class="body">
+ <p>Where I work at the <a href="http://www.uio.no/">University of
+Oslo</a>, we use the
+<a href="http://sourceforge.net/projects/cerebrum/">Cerebrum user
+administration system</a> to maintain users, groups, DNS, DHCP, etc.
+I've known since the system was written that the server is providing
+an <a href="http://en.wikipedia.org/wiki/XML-RPC">XML-RPC</a> API, but
+I have never spent time to try to figure out how to use it, as we
+always use the bofh command line client at work. Until today. I want
+to script the updating of DNS and DHCP to make it easier to set up
+virtual machines. Here are a few notes on how to use it with
+Python.</p>
+
+<p>I started by looking at the source of the Java
+<a href="http://cerebrum.svn.sourceforge.net/viewvc/cerebrum/trunk/cerebrum/clients/jbofh/">bofh
+client</a>, to figure out how it connected to the API server. I also
+googled for python examples on how to use XML-RPC, and found
+<a href="http://tldp.org/HOWTO/XML-RPC-HOWTO/xmlrpc-howto-python.html">a
+simple example in</a> the XML-RPC howto.</p>
+
+<p>This simple example code show how to connect, get the list of
+commands (as a JSON dump), and how to get the information about the
+user currently logged in:</p>
+
+<blockquote><pre>
+#!/usr/bin/env python
+import getpass
+import xmlrpclib
+server_url = 'https://cerebrum-uio.uio.no:8000';
+username = getpass.getuser()
+password = getpass.getpass()
+server = xmlrpclib.Server(server_url);
+#print server.get_commands(sessionid)
+sessionid = server.login(username, password)
+print server.run_command(sessionid, "user_info", username)
+result = server.logout(sessionid)
+print result
+</pre></blockquote>
+
+<p>Armed with this knowledge I can now move forward and script the DNS
+and DHCP updates I wanted to do.</p>
