dnscacheaudit is a simple Perl utility to audit entries in the BIND cache. At the end of each run, it creates a PDF report showing the number of domains in the BIND cache that have a different IP address in the cache than the reference servers. This utility is inspired by the CacheAudit utility by Jose Avila.
Avahi is a framework for Multicast DNS Service Discovery (mDNS/DNS-SD a.k.a. Zeroconf) on Linux. It allows programs to publish and discover services running on a local network with no specific configuration. For example, you can plug into a network and instantly find printers to print to, files to look at, and people to talk to.
slapi-dnsnotify is a plugin for OpenLDAP or other LDAP servers. It watches for changes in the serial number of a DNS zone stored in the LDAP server, and notifies DNS slave servers to refresh their copy of the zone. It can also increment the serial number of a zone whenever changes in that zone are made.
NetDB is a suite of applications for managing DNS and DHCP in a distributed, collaborative fashion. It is geared towards very large networks and can support thousands of nodes, networks, and users. NetDB consists of a database with Web, command-line, and RMI interfaces. Users use the NetDB Web and command-line interfaces to keep the data in NetDB up to date. The GSSAPI-secured RMI interface can be used to create site-specific tools to manage and use NetDB data. NetDB includes scripts for generating ISC BIND zonefiles and ISC DHCP configuration files.
Bind DLZ on Rails is a Web-based user interface for managing BIND with the bind-dlz extensions on a MySQL 5.0 backend. BIND is a DNS server, and the bind-dlz extensions enhance BIND with support for database backeneds. This simplifies the management of thousands of zones and provides added redundancy (by way of database replication).
