Argus

Argus is a generic IP network transaction auditing tool. Argus runs as an application level daemon, promiscuously reading network datagrams from a specified interface, and generates network traffic status records for the network activity that it encounters.

Fremont

Fremont is a research prototype for discovering key network characteristics, such as hosts, gateways, and topology. It runs on SunOS, and has been tested on both Sun3 and Sun4 hardware, on SunOS 4.1.1. The ARPwatch and RIPwatch Explorer Modules use the Sun's Network Interface Tap. This directory contains information, the latest version and patches.

HPing

A network analysis tool. HPing is a tool which enables you to send packet with non traditional IP stack parameters and gather information from the results of the incoming packets (which were generated in responds to the sent packet), this information isn't displayed by regular application since much of it is for debugging and internal network functionality.

Legion

This is a Win32 file share scanner and an improved version of Legion 1.x. Some of the features includes a "user-friendly" interface, multiple scan configurations, treeview of remote hosts, text reporting, mounting drives with one click and share level brute force plug-in.

nmap

nmap is a utility for port scanning large networks using various scanning techniques. nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings. Nmap also offers flexible target and port specification, decoy scanning, determination of TCP sequence predictability characteristics, and output to machine parseable or human readable log files.

nss

nss is a perl script that scans either individual remote hosts or entire subnets of hosts for various simple network security problems. The majority of the tests can be performed by any non-privileged user on a typical Unix machine.

Rscan

Rscan (previously called securscan) is a tool that lets a system administrator run complex or simple scanner scripts on any number of machines in a heterogeneous environment.

SAINT

SAINT is the Security Administrator's Integrated Network Tool. In its simplest mode, it gathers as much information about remote hosts and networks as possible by examining such network services as finger, NFS, NIS, ftp and tftp, rexd, statd, and other services. The information gathered includes the presence of various network information services as well as potential security flaws -- usually in the form of incorrectly setup or configured network services, well-known bugs in system or network utilities, or poor or ignorant policy decisions. It can then either report on this data or use a simple rule-based system to investigate any potential security problems.

SATAN

SATAN, the System Administrator Tool for Analyzing Networks, is a network security analyzer designed by Dan Farmer and Wietse Venema. SATAN scans systems connected to the network noting the existence of well known, often exploited vulnerabilities. For each type of problem found, SATAN offers a tutorial that explains the problem and what can be done.

Strobe

Strobe is a security/network tool that locates and describes all listening tcp ports on a (remote) host or on many hosts in a bandwidth utilisation maximising, and process resource minimising manner.

Tiger

Tiger (from Texas A & M University) is a set of scripts that scan a Unix system looking for security problems, in the same fashion as COPS.

YAPS

YAPS stands for Yet Another Port Scanner. It is a Windows95/NT intelligent IP port scanner. It can quickly analyze a single computer or identify all computers on a specified network.
