urt-service

Run Urban Terror server using systemd, screen and mail applications on a Linux operating system.

Note: Tested to work on a Debian Wheezy/Jessie operating system, may require alterations for it to work on other operating systems.

Note: It is assumed email is already configured and required packages are installed on the Linux system being used.

Features

  • Urban Terror starts up automatically at system start up (runs as a service/daemon).
  • Notification of Urban Terror service failures are sent via email.

Required Packages

  • git
  • mailutils (/usr/bin/mail)
  • nano
  • screen
  • systemd

Sending an Email When a Unit Fails Works as Follows...

  • Two files will be required to achieve this: an executable for sending the email and a .service for starting the executable.
  • Add "OnFailure=status-send-email@%n.service" without double quotes to the [Unit] section of any unit file to receive emails on failures.
  • %n passes the unit's name to the template. %i is the instance name. Refer to the man page systemd.unit for further details.
