Gentoo network monitoring and analysis project
Wireshark is the world's foremost network protocol analyzer, and is the de
facto (and often de jure) standard across many industries and educational
institutions. Wireshark has a rich feature set which includes 1) deep
inspection of hundreds of protocols, with more being added all the time, 2)
live capture and offline analysis, 3) standard three-pane packet browser, 4)
captured network data can be browsed via a GUI, or via the TTY-mode TShark
utility, 5) the most powerful display filters in the industry, 6) rich VoIP
analysis, 7) read/write many different capture file formats: tcpdump (libpcap),
Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network
General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®,
Network Instruments Observer, Novell LANalyzer, RADCOM WAN/LAN Analyzer,
Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime,
WildPackets EtherPeek/TokenPeek/AiroPeek, and many others, 8) capture files
compressed with gzip can be decompressed on the fly, 9) live data can be read
from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame
Relay, FDDI, and others, 10) decryption support for many protocols, including
IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2, 11) coloring rules
can be applied to the packet list for quick, intuitive analysis, 12) output can
be exported to XML, PostScript®, CSV, or plain text.
