The dnsutl package is a collection tools to make administering DNS easier. These include programs for: * Generating the reverse DNS mapping by using the DNS forward mapping. This is useful for producing a self-consistent DNS configuration. * Generating the /etc/ethers file by using a bogus record type. * Generating the /etc/hosts file by using the DNS forward mapping. * Generating the /etc/bootptab file by using the MAC and IP information. * Generating the /etc/netgroup file by using the DNS forward mapping. * Generating the Sun /etc/bootparams file by using the MAC and IP information. * Checking the new-style /etc/named.conf files for self-consistency. * Checking the old-style /etc/named.boot files for self-consistency. * Generating the DNS forward mapping by using the /etc/hosts file. This could be a first step to configuring your DNS server. * Generating the /etc/dhcp.conf file by using the MAC and IP information. All of these programs are both faster than shell scripts, and more robust when faced with all the peculiar semantics of DNS resource files. They even understand the $include directive.

getdns is a modern asynchronous DNS API. It implements DNS entry points from a design developed and vetted by application developers, in an API specification edited by Paul Hoffman. With the development of this API, we intend to offer application developers a modernized and flexible way to access DNS security (DNSSEC) and other powerful new DNS features; a particular hope is to inspire application developers towards innovative security solutions in their applications.

[from web site] This is a simple Python script to register your dynamic IP address using the NIC V2.0 protocol. We aim to be fully compliant with the dyndns client specification. Starting with version 0.141, we use https by default and will fall back to plain http if a timeout occurs. We currently support all options and latest recommendations by Dyndns. Ipcheck is easy to install and very easy to use. Root access is not required and no configuration files are needed. Just specify your username, password and hostname(s) on the command line (or cron entry). You can specify the interface (default tun0) to search for your ip address on or use web based IP detection. There is also direct support for determining the IP address on the following devices: Linksys (-L), Netgear (-N), Draytek (-D), Netopia (-O), HawkingTech (-H), Cisco 667i (-C), Cisco 700 series (-I), ZyXEL Prestige (-Z), SMC Barricade (-S)

MyDNS is a free DNS server for UNIX implemented from scratch and designed to utilize the MySQL database for data storage. Its primary objectives are stability, security, interoperability, and speed, though not necessarily in that order. MyDNS does not include recursive name service, nor a resolver library. It is primarily designed for organizations with many zones and/or resource records who desire the ability to perform real-time dynamic updates on their DNS data via MySQL.

This directory contains a Python module that implements a DNS (Domain Name Server) client, plus additional modules that define some symbolic constants used by DNS (dnstype, dnsclass, dnsopcode).

Tool suite for analysis and visualization of Domain Name System (DNS) behavior, including its security extensions (DNSSEC). The Web-based analysis is run from the same software.

Validns is a standalone command line RFC 1034/1035 zone file validation tool that, in addition to basic syntactic and semantic zone checks, includes DNSSEC signature verification and NSEC/NSEC3 chain validation, as well a number of optional policy checks on the zone.

Unbound is designed as a set of modular components, so that also DNSSEC (secure DNS) validation and stub-resolvers (that do not run as a server, but are linked into an application) are easily possible. Goals: * A validating recursive DNS resolver. * Code diversity in the DNS resolver monoculture. * Drop-in replacement for BIND apart from config. * DNSSEC support. * Fully RFC compliant. * High performance, even with validation enabled. * Used as: stub resolver, full caching name server, resolver library. * Elegant design of validator, resolver, cache modules. o provide the ability to pick and choose modules. * Robust. * In C, open source: The BSD license. * Smallest as possible component that does the job. * Stub-zones can be configured (local data or AS112 zones). Non-goals: * An authoritative name server. * Too many Features.

A script that tries to update the serial inside a DNS zonefile with sane values if the file has changed during edit.

Aewan is a multi-layered ascii-art/animation editor that produces both stand-alone cat-able art files and an easy-to-parse format for integration in your terminal applications. Aewan is a curses-based program that allows for the creation and editing of ascii art. The user is able to move the cursor around the screen by means of the arrow keys and 'paint' characters by pressing the corresponding keys. There are dialog boxes that allow the user to choose foreground and background colors, as well as bold and blink attributes. The user may also select rectangular areas of the canvas in order to move, copy and paste them. Aewan also supports 'intelligent' horizontal and vertical flipping (e.g. converts '\' to '/', etc).
