The goal of FireStarter is to provide easy to use, yet powerful, graphical tools for setting up, administrating and monitoring firewalls for Linux machines.

tcpick is a textmode sniffer; it tracks tcp streams, shows the status, reassembles and saves the data captured in files or displays them in the terminal in different modes (ascii, hex..). There is a color-mode. Useful to get files passively.

Output spool reader for Snort! This program decouples output overhead from the Snort network intrusion detection system and allows Snort to run at full speed. It takes input and output plugins and can therefore be used to convert almost any spooled fil

pcapsipdump is libpcap-based SIP sniffer with per-call sorting capabilities. It writes SIP/RTP sessions to disk in a same format, as "tcpdump -w", but one file per SIP session (even if there is thousands of concurrent SIP sessions). Getting started: http://pcapsipdump.sf.net/

It is a versatile DNS Proxy server with DNS firewall which filters DNS traffic between local computer and DNS servers with flexible rules, supports blocking by IP geography, caching, import/export rules into XML. With a click of a button acts as a DNS proxy (or DNS server), supports multiple client authentication methods, calculates statistics for DNS servers and proxy clients, supports load balancing between multiple upstream DNS servers.

MINT allows a network engineer to easly set up multicast sources and recievers to test a multicast network's ability to send and recieve packets. It is particuarly usefull in lab environments.

IPCAD runs captures traffic on the specified interfaces (BPF, PCAP, divert, tee, ULOG, IPQ), and records the traffic for later retrieval and analysis. Traffic exported via RSH or NetFlow.

OpenLLDP is an Open Source implementation of the IEEE standard 802.1AB Link Layer Discovery Protocol (LLDP). The OpenLLDP project aims to provide a comprehensive implementation of IEEE 802.1AB to help foster adoption of the LLDP protocol.

** As of Snort 2.9.7.6, we are longer releasing Snort on SourceForge. Please head to http://www.snort.org from now on!** **As of June 2017, the mailing lists are no longer on SourceForge, and have moved to https://lists.snort.org** Snort is a libpcap-based sniffer/logger which can be used as a network intrusion detection and prevention system. It uses a rule-based detection language as well as various other detection mechanisms and is highly extensible.

Knocker is a simple, versatile, and easy-to-use TCP security port scanner written in C, using threads. It is able to analyze hosts and the network services which are running on them. It is available for Linux, FreeBSD, Unix, and Windows95/98/2000.

Weblooker monitors serveral services on multiple systems for their status, up- and downtimes. A webgui and Android client to view the current status and logged downtimes is available as separately package.

Distributed Nagios eXecutor (DNX) is comprised of, a NEB module, server, and client daemons which allow the check plug-ins to execute across multiple "worker nodes" in a load distribution cluster.

Traff sniffs you network interfaces and accounts the traffic on a IP basis. The configuration is very flexible allowing you to create different/multiple accounting rules. The collected data is stored using Mysql, PgSQL, Syslog or files.

Flexible web-based firewall log analyzer, supporting netfilter and ipfilter, ipfw, ipchains, cisco routers and Windows XP system logs, and mysql or postgresql database logs using the iptables ULOG or NFLOG target of netfilter others mapped to the ulogd format with a view. Fully supports IPv6 for database logs, and netfilter and ipfilter system file logs. Also supports Maxmind's GeoIP version 2 location databases. For Linux, FreeBSD, OpenBSD, Solaris, OSX,etc.

Active dictionary attack on WEP keys in WLAN networks.

The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it.

wmDownload is a simple WindowMaker dockapp that displays how much data you\'ve recieved on each eth and ppp device installed on your machine in one display mode and the data transfer rate in another.

Given SNMP-capable routers and switches, sdig can turn an IP address, DNS/WINS host name or a MAC address into a port description. Sdig will run on most any platform that net-snmp supports. It currently compiles on FreeBSD, Linux and Solaris.

Autostatus is a network monitoring program for hosts and services. It is designed to be fast and extremely easy to use. It monitors by icmp pings and by attempting TCP connections to specified ports.
