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.
DNSDusty is an uncomplicated Web-based DNS management tool. It does all of its modifications via signed dynamic updates, and gets info on zones via zone transfers. Thus, it does not require any external databases, and plays along well with other tools that do dynamic updates (such as DHCP). DNSDusty is written as a Perl CGI script, so it should work with most Web servers.
sql2data fetches DNS information from an SQL database and dumps then in tinydns-data format into the file 'data'. Additional static DNS data from the text file static_data are copied into 'data'. sql2data optionally executes 'make' upon successful export/dump. Backups can be made to the files old_data and good_data.cdb. Optionally, DNS NOTIFY packets may be sent to the different nameservers referenced for the different zones.
tinydyndns is a simple but powerful dynamic DNS solution that uses djbdns. It cooperates with the djbdns package to publish dynamic IP addresses authenticated through POP connections. On successfully authenticated POP connections, the tinydyndns-update program manipulates tinydns' constant database "data.cdb" directly without rebuilding it; this makes the dynamic DNS solution use very few system resources. Using a POP service for authentication saves the work for installing special client software, since POP clients are available for every common network-aware operating system. To provide the DNS and POP service, tinydyndns cooperates with djbdns, qmail, and cvm.
ext-Dns is a core library, an extensible forward DNS server, and some additional tools designed to create DNS server solutions which are able to do any additional operation at the resolution level (running commands, rewritting replies, gathering stats, and so on), without any limit. It provides a ready-to-use solution in case you want to build a DNS server which takes additional actions at the resolution level in an easy way. That is, its design is focused on allowing people to implement whatever they like when a request is received, freeing them from most of the details which involves handling DNS protocol.
