Roster is DNS management software for use with Bind 9. It is licensed under the BSD license. It is written in Python, and uses a MySQL database with an XML-RPC front-end. It contains a set of command line user tools that connect to the XML-RPC front-end. The config files for BIND are generated from the MySQL database, so a live MySQL database is not needed. The software has four basic components. The core includes the database interface and core API, and contains the authorization layer. The server is an SSL enabled multi-threaded XML-RPC server. It also contains the LDAP authentication layer. The config manger creates BIND config files using the core API, and handles pushing the files to their appropriate servers. The user tools contain over 20 tools to create, list, and remove records, zones, views, DNS servers, DNS server sets, groups, users, and the assignments between them all. There is currently support for views, many DNS servers in many configurations, IPv6, user/group authorization, LDAP authentication, and Unicode hosts.
