Wireshark 4

The most popular and well-known network protocol analyzer in the world is called Wireshark. It is the de facto (and frequently de jure) standard in many commercial and non-profit businesses, government organizations, and educational institutions. It allows you to view what’s occurring on your network at a microscopic level. The ongoing development of Wireshark, which was initiated by Gerald Combs in 1998, is made possible by the voluntary efforts of networking specialists worldwide.

One of Wireshark’s distinguishing characteristics is its display filters, which are strengthened and improved in version 4.0. These enhancements enable you to perform arithmetic and allow you greater control over how numerous instances of the same field are handled, among other things.

The program can read capture files from tcpdump (libpcap), NAI Sniffer (compressed and uncompressed), Sniffer Pro, NetXray, snoop, Shomiti Surveyor, AIX s retrace, Microsoft Network Monitor, Novell s LANalyzer, RADCOM s WAN/LAN Analyzer, HP-UX nettl, ISDN4BSD, Cisco Secure IDS log, the pppd log (dump-format), and the AG Group s/Wildpacket Etherpeek.
