Tcpdump allows you to dump the traffic on a network. It can be used to print out the headers and/or contents of packets on a network interface that matches a given expression. You can use this tool to track down network problems, to detect many attacks, or to monitor the network activities. Requires Libpcap.

httpry is a specialized packet sniffer designed for displaying and logging HTTP traffic. It is not intended to perform analysis itself, but instead to capture, parse, and log the traffic for later analysis. It can be run in real-time displaying the live traffic on the wire, or as a daemon process that logs to an output file. It is written to be as lightweight and flexible as possible, so that it can be easily adaptable to different applications. It does not display the raw HTTP data transferred, but instead focuses on parsing and displaying the request/response line along with associated header fields.

rtpBreak detects, reconstructs and analyzes any RTP [rfc1889] session through heuristics over the UDP network traffic. It works well with SIP, H.323, SCCP and any other signaling protocol. In particular, it does not require the presence of RTCP packets (voipong needs them) that are not always transmitted from the recent VoIP clients.

ipgrab is a packet sniffing tool, based on the Berkeley packet capture library, that prints complete data-link, network and transport layer header information for all packets it sees. Specifically, this program reads and parses packets from the link layer through the transport layer, dumping explicit header information along the way.

Snortalog is a powerful Perl script that summarizes Snort logs, making it easy to view any network attacks detected by Snort. It can generate charts in HTML, PDF, and text output. It works with all versions of Snort, and can analyze logs in three formats: syslog, fast, and full snort alerts. Moreover, it is able to summarize other logs like Fw-1 (NG and 4.1), Netfilter, and IPFilter in a similar way.

Wireshark is a GTK+-based network protocol analyzer that lets you capture and interactively browse the contents of network frames. The goal of the project is to create a commercial-quality analyzer for Unix and Win32 and to give Wireshark features that are missing from closed-source sniffers. Screenshot available here.

TNV visualizes pcap data to graphically depict network packets, links, and ports for network traffic analysis to facilitate learning what constitutes 'normal' behavior, investigating security events, or network troubleshooting. It depicts network traffic by visualizing packets and links between local and remote hosts. It is intended for network traffic analysis to facilitate learning what constitutes 'normal' activity on a network, investigating packet details and security events, or for network troubleshooting. It can open saved libpcap (from tcpdump, windump, ethereal, etc.) formatted files or capture live packets on the wire, and export data in libpcap format or save the data to a MySQL database to enable the examination of trends over time.
