Sauron is a scalable system for management of DNS and DHCP services. Sauron can dynamically generate complete DNS and DHCP configurations from a central SQL-database. Automatic generation of DNS "reverse" zones (with support for smaller than C-class reverse delegations) is supported. Sauron comes with web interface and command-line interface. The web interface comes with user/group based access controls for distributed management.
Sauron was originally designed and written by Timo Kokkonen at the Computing Center of University of Jyvaskyla. In 1999, when work on Sauron was started, it was meant to provide a simple web based interface for letting multiple users simultaneously manage DNS zone files, but it has since grown into a full featured DNS & DHCP management software.
Sauron is still under development, but it has been in production use since early 2001, managing the campus area network (CAN) with over 10,000 computers at University of Jyvaskyla, Finland.
In January 2003, Sauron was publicly released under the GNU General Public License (GPL).
