Wireshark

Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions.

Features (as listed on the website)

Wireshark has a rich feature set which includes the following:

  •     Deep inspection of hundreds of protocols, with more being added all the time
  •     Live capture and offline analysis
  •     Standard three-pane packet browser
  •     Multi-platform: Runs on Windows, Linux, macOS, Solaris, FreeBSD, NetBSD, and many others
  •     Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
  •     The most powerful display filters in the industry
  •     Rich VoIP analysis
  •     Read/write many different capture file formats: tcpdump (libpcap), Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, NetScreen snoop, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
  •     Capture files compressed with gzip can be decompressed on the fly
  •     Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platform)
  •     Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
  •     Coloring rules can be applied to the packet list for quick, intuitive analysis
  •     Output can be exported to XML, PostScript®, CSV, or plain text
