This is a page about improving or modifying OpenHatch.

We call that "Hacking OpenHatch," and there is a whole category of pages about that.


The basics

  • is the main OpenHatch box, which runs the website.
  • is the secondary server for OpenHatch. It hosts the Hudson continuous integration server, as well as Nagios!
  • The Nagios configuration is owned by a user called nagios on


  • We use ssh keys for login.
  • If you want SSH access to that account, file a bug requesting it, and attach an SSH key. You should hear back within 2 days; if you don't hear back by then, try to find paulproteus or jesstess on IRC.
  • Then you can do:
  • You'll know it's working if you are logged in. If you see a "Password:" prompt, then it is not working.


Viewing the web interface, and handling the daemon

  • On linode2, ~/nagios/secrets/ contains the mailman and Nagios web interface passwords.
  • View the Nagios web interface at
  • To restart the Nagios daemon, run
sudo /etc/init.d/nagios3 restart

In case of emergency


  1. Send Nagios notifications to IRC (#openhatch-auto?)?
  2. Make the Nagios web interface world-viewable.
  3. Version the monitoring configurations.
  4. Send SMS alerts to people who want them.
  5. Add historical trending (Munin)?
