Software and Services
Jalapeno uses the standard NPG iptables firewall. It allows ssh, DNS, and CUPS ipp connections.
Named provides DNS hostname resolution for the farm.physics.unh.edu backend network. DNS configuration files are located in the /var/named directory.
Note: Print services are being relocated to corn.
CUPS is configured to provide access to the NPG printer Wigner located in DeMeritt room 362. Authentication is required to use the printer, and access is restricted to NPG group members. Cups configuration is located in /etc/cups/cupsd.conf and printer configuration is located in /etc/cups/printers.conf.
The cups web interface can be accessed at http://jalapeno.unh.edu:631

printtracker.py is a simple python script which sends monthly reports of print usage gathered from the cups page log. It records the number of pages printed by each user on the system.
The script can run in two different modes. The weekly mode is configured in crontab to run before the normal cron.weekly tasks. This is necessary because it needs to read the logs before they're emptied by logrotate, which happens when the normal cron.weekly jobs run. The monthly routine that e-mails the final monthly report is run by a script in cron.monthly.
