For verifying changes to /etc/audisp/audisp-remote.conf on servera (to dispatch messages to serverb), the script is checking explicitly for an IP address (of serverb).
So if I have a setting such as remote_server=serverb.lab.example.com tha grading script fails it :-). FYI, for the updated version of the course.
See /usr/local/lib/lab-audit-review lines 68-73
