These include Ethernet, IEEE 802.11, PPP, and loopback. There are multiple types of networks that data can be read from.One key benefit of using this program is that it is completely free to use. The second is from data that has been made into a file of already-captured packets. The first is “from the wire” which means that the data comes from a live network connection. There are two ways that data can be captured with this program.Some of the main features of this program include the following: Some Windows versions requires WinPcap to be installed.Wireshark is a program that is used for network troubleshooting. Coloring rules can be applied to the packet list, which eases analysis.Hundreds of protocols are supported, with more being added all the time.Capture files compressed with gzip can be decompressed on the fly.Read/write many different capture file formats: tcpdump (libpcap), NAI's Sniffer (compressed and uncompressed), Sniffer Pro, NetXray, Sun snoop and atmsnoop, Shomiti/Finisar Surveyor, AIX's iptrace, Microsoft's Network Monitor, Novell's LANalyzer, RADCOM's WAN/LAN Analyzer, HP-UX nettl, i4btrace from the ISDN4BSD project, Cisco Secure IDS iplog, the pppd log (pppdump-format), the AG Group's/WildPacket's EtherPeek/TokenPeek/AiroPeek, Visual Networks' Visual UpTime and many others.

Live capture and offline analysis are supported.The most powerful display filters in the industry.Multi-interface: Along with a standard GUI, Wireshark includes TShark, a text-mode analyzer which is useful for remote capture, analysis, and scripting.Multi-platform: Runs on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others.Wireshark has a rich feature set which includes the following: Hundreds of developers around the world have contributed to it, and it it still under active development. It is the continuation of a project that started in 1998. Wireshark is one of the world's foremost network protocol analyzers, and is the standard in many parts of the industry.
