nss-mdns is a plugin for the GNU Name Service Switch (NSS) functionality of the GNU C Library (glibc) which provides host name resolution via Multicast DNS (a.k.a. Zeroconf, a.k.a. Apple Rendezvous, a.k.a Apple Bonjour). This effectively allows name resolution by common Unix/Linux programs in the ad-hoc mDNS domain .local.
PynamicD is a client/server interface for manipulating secondary DNS servers. It is designed as a lightweight interface which could be used from the command line, inside a shell script, or from a Web interface. The pynamic client connects to the pynamicd server, which rans on the secondary DNS server and provides the ability to add zones, delete zones, and conditionally restart the DNS server. It uses blowfish encryption with a pre-shared key and maintains a list of allowed clients. Tests are done to detect duplicates and configuration file corruption. It also features checks for locks held by the vi editor.
OpenVISP Admin is a fork of Postfix Admin. Its aim is to provide a unique ISP tool as a Web panel for end users, postmasters, and site administrator to manage their data. It allows site administrators to update amavisd-new values, spam-assassin values, greylisting, domains checks, and sender verification. It can also provide datacenter admins with a central point of access, by having APC Masterswitch configuration and access, hosting access requests, and PPTP access and statistics views.
