For all front end computers:
monit configuration was changed to allow workstations access to the web interface
ntp configuration was changed to write the drift file to /var/log/ (default was trying to write to a read-only file system)
To install it did the following:
1. restart monit to new configuration (/etc/init.d/monit restart)
2. Using firefox, go to the monit web page (http://name), go into ntp control page and press RESTART
Roughly an hour later, the /var/log/ntp.drift file was created, and the error message that it couldn't be created is no longer seen.
