Wireshark 4.4.2

Wireshark Overview

Wireshark has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session.

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 iplog, the pppd log (pppdump-format), and the AG Group s/Wildpacket Etherpeek.

Wireshark can also read traces from Lucent/Ascend WAN routers and Toshiba ISDN routers. It can compress files with gzip, and Wireshark will decompress them on the fly.
