  31         <p>Where I work at the <a href="http://www.uio.no/">University of
  32 Oslo</a>, we use the
  33 <a href="http://sourceforge.net/projects/cerebrum/">Cerebrum user
  34 administration system</a> to maintain users, groups, DNS, DHCP, etc.
  35 I've known since the system was written that the server is providing
  36 an <a href="http://en.wikipedia.org/wiki/XML-RPC">XML-RPC</a> API, but
  37 I have never spent time to try to figure out how to use it, as we
  38 always use the bofh command line client at work.  Until today.  I want
  39 to script the updating of DNS and DHCP to make it easier to set up
  40 virtual machines.  Here are a few notes on how to use it with
  41 Python.</p>
  42
  43 <p>I started by looking at the source of the Java
  44 <a href="http://cerebrum.svn.sourceforge.net/viewvc/cerebrum/trunk/cerebrum/clients/jbofh/">bofh
  45 client</a>, to figure out how it connected to the API server.  I also
  46 googled for python examples on how to use XML-RPC, and found
  47 <a href="http://tldp.org/HOWTO/XML-RPC-HOWTO/xmlrpc-howto-python.html">a
  48 simple example in</a> the XML-RPC howto.</p>
  49
  50 <p>This simple example code show how to connect, get the list of
  51 commands (as a JSON dump), and how to get the information about the
  52 user currently logged in:</p>
  53
  54 <blockquote><pre>
  55 #!/usr/bin/env python
  56 import getpass
  57 import xmlrpclib
  58 server_url = 'https://cerebrum-uio.uio.no:8000';
  59 username = getpass.getuser()
  60 password = getpass.getpass()
  61 server = xmlrpclib.Server(server_url);
  62 #print server.get_commands(sessionid)
  63 sessionid = server.login(username, password)
  64 print server.run_command(sessionid, "user_info", username)
  65 result = server.logout(sessionid)
  66 print result
  67 </pre></blockquote>
  68
  69 <p>Armed with this knowledge I can now move forward and script the DNS
  70 and DHCP updates I wanted to do.</p>
