Nmap ("Network Mapper") is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap ... [More] uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. [Less]

BIND (Berkeley Internet Name Domain) is an implementation of the Domain Name System (DNS) protocols and provides an openly redistributable reference implementation of the major components of the ... [More] Domain Name System, including a Domain Name System server, a Domain Name System resolver library and tools for verifying the proper operation of the DNS server. [Less]

Tcpdump prints out the headers of packets on a network interface that match the boolean expression.

Netcat is a featured networking utility which reads and writes data across network connections, using the TCP/IP protocol. It is designed to be a reliable "back-end" tool that can be used directly ... [More] or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities. [Less]

OpenWrt is described as a Linux distribution for embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This ... [More] frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. [Less]

PF (Packet Filter) is OpenBSD's system for filtering TCP/IP traffic, doing Network Address Translation, normalizing and conditioning TCP/IP traffic and providing bandwidth control and packet ... [More] prioritization. PF has also been ported to FreeBSD, NetBSD, and DragonFly BSD, and is an integral part of MirBSD. [Less]

Iproute2 is a collection of utilities for controlling TCP / IP networking and traffic control in Linux.

Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP server. It is designed to provide DNS and, optionally, DHCP, to a small network. It can serve the names of local machines which are ... [More] not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines. [Less]

Small, secure dns cache and resolver written by Daniel J. Bernstein, the author of qmail. djbdns is extremely fast, very secure and easy to configure (think 'opposite of bind zone files').

The PowerDNS server daemon is a versatile nameserver which supports a large number of backends. These backends can either be plain zonefiles or be more dynamic in nature. Additionally, through use of ... [More] clever programming and caching techniques, PowerDNS offers very high domain resolution performance. Prime examples of backends include relational databases, but also (geographical) loadbalancing and failover algorithms. The PowerDNS recursor daemon which is also part of the PowerDNS compilation is a dedicated high performance recursive (aka caching-only) Nameserver that already powers some larger broadband ISPs and as of late learned to embed Lua Scripts making it possible to manipulate DNS Answers from within those Scripts.
