The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network-links. MRTG generates HTML pages containing GIF/PNG images which provide a live visual representation of this traffic.
Calamaris parses the logfiles of a wide variety of Web proxy servers and generates reports about peak-usage, request-methods, status-report of incoming and outgoing requests, second and top-level destinations, content-types, and performance.
darkstat is an ntop-workalike network statistics gatherer. It runs as a background process on a cable or DSL router, uses libpcap to capture network traffic, and has a Web interface that serves up reports of statistics such as data transferred by host, port, and protocol. It also has a neat bandwidth usage graph.
Angst is an active sniffer, based on libpcap and libnet. It dumps into a file the payload of all the TCP packets received on the specified ports. It implements two methods for active sniffing. Angst is able to monitor ARP requests, and after enabling IP forwarding on the local host, it sends ARP replies mapping all IPs to the local MAC address. Also, it can flood the local network with random MAC addresses (like macof), causing switches to send packets to all ports.

Endian Firewall is an all-in-on Linux security distribution that turns any system into a full-featured security appliance. It features a stateful packet inspection firewall, application-level proxies for various protocols (HTTP, POP3, SMTP), anti-virus support, virus and spam filtering for email traffic (POP and SMTP), content filtering of Web traffic, and a "hassle free" VPN system based on OpenVPN.

L7-filter is a packet classifier for Netfilter that identifies packets based on application layer (OSI layer 7) data. This means that it is able to classify packets as HTTP, FTP, Gnucleus, Kazaa, etc., regardless of ports. It complements existing matches that classify based on port numbers, packet length, TOS bits, and so on. Combined with Linux QoS, it allows for full layer 7 packet shaping.

fping is a ping-like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a target host is responding. fping differs from ping in that you can specify any number of targets on the command line, or specify a file containing the lists of targets to ping. Instead of sending pings to one target until it times out or replies, fping will send out a ping packet and move on to the next target in a round-robin fashion.
Just For Fun Network Management System is a PHP-based network management system that features an integrated syslog, Tacacs, TFTP configuration downloading, SNMP polling, SNMP traps, journalling, auto-discovery, performance graphs (RRD), SLAs, and a lot more. It uses MySQL or PostgreSQL as the backend and works under Linux and Windows.
IPTraf is an ncurses-based IP LAN monitor that generates various network statistics including TCP info, UDP counts, ICMP and OSPF information, Ethernet load info, node stats, IP checksum errors, and others.
Kismet is an 802.11 layer 2 wireless network detector, sniffer, and intrusion detection system. It will work with any wireless card which supports raw monitoring (rfmon) mode, and can sniff 802.11b, 802.11a, 802.11g, and 802.11n traffic (device drivers permitting). It identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and inferring the presence of non-beaconing networks via data traffic.
LogAnalyzer is a Web front-end for syslog and other network event data. It provides easy browsing, searching, basic analysis, and some graphics. Data is taken from databases or plain syslog text files, so LogAnalyzer does not require changes to an existing logging infrastructure. Depending on the log data present, it can process syslog messages, Windows event log entries, and some more exotic things. Its troubleshooting support enables users to quickly find solutions to problems seen in the log data. LogAnalyzer was previously called phpLogCon, and has been renamed since v3.

MoSShE (MOnitoring in Simple SHell Environment) is a simple,
lightweight (both in size and system requirements) server monitoring
package designed for secure and in-depth monitoring of a handful of
typical/critical Internet systems. It supports email alerts and SLA
monitoring out of the box, and whatever you can script. The system is
programmed in plain (Bourne) SH, and made to be compatible with BASH and
Busybox so it can easily be deployed on embedded systems. Monitoring
is designed to be distributed over multiple systems, usually running
locally. As no parameters are accepted from the outside, checks cannot
be tampered or misused from outside. The system is designed to allow
decentralized checks and evaluation as well as classical agent-based
checks with centralized data accumulation. Agent data is transferred via
HTTP, so available Web servers can be co-used for agent data transfer.
Each agent creates simple (static) HTML pages with full and condensed
status reports on each system, allowing simple local checks.
