Wireshark 2.4.1


Wireshark Icon


Wireshark is a popular network protocol analyzer. It lets you capture and interactively browse the traffic running on a computer network. It's the de facto (and often de jure) standard across many industries and educational institutions. It's a cross-platform tool, using the Qt widget toolkit in current releases to implement its user interface, and using pcap to capture packets. It is developed and maintained by a global team of protocol experts, and it is an example of a disruptive technology.

Wireshark allows the user to put the network interfaces that support promiscuous mode into that mode, in order to see all traffic visible on that interface, not just traffic addressed to one of the interface’s configured addresses and broadcast / multicast traffic.

Wireshark used to be known as Ethereal. If you're still using Ethereal, it is strongly recommended that you upgrade to Wireshark as Ethereal is unsupported and has known security vulnerabilities.

You can use Wireshark for both personal and commercial use without paying any fee.

Key Features:
  • Deep inspection of hundreds of protocols, with more being added all the time
  • Live capture and offline analysis
  • Standard three-pane packet browser
  • 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
