      Using the new SSH server feature:
      https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+SSH

      We accidentally set it to a port below 1024 when the server doesn't run as root. The server becomes unusable, printing this message to the browser when attempting to access it:

      We had to manually go in and edit the org.jenkinsci.main.modules.sshd.SSHD.xml file to change the port number in order to make the server boot.
