Wireshark is a widely used network analysis tool that provides detailed insights into network traffic. Developed by the Wireshark community, it is an open-source software that allows users to capture, analyze, and interpret network packets in real-time.

With its user-friendly interface and extensive protocol support, Wireshark has become an indispensable tool for network administrators, security professionals, and developers. It can be utilized for various purposes, including network troubleshooting, protocol development, network security analysis, and educational research.

One of the key features of Wireshark is its ability to capture packets from different network interfaces and protocols. It provides a live capture option, enabling users to observe network traffic in real-time. Additionally, it supports the analysis of encrypted protocols, making it a valuable tool for identifying potential security vulnerabilities.

Wireshark's powerful filtering capabilities allow users to focus on specific network packets and extract relevant information. It provides detailed packet-level analysis, displaying important details such as source and destination IP addresses, packet timing, and protocol-specific data. This level of granularity enables users to diagnose network issues efficiently.

Furthermore, Wireshark offers a range of advanced features, including packet decryption, protocol dissectors, and the ability to export captured data for further analysis. Its extensibility through custom plugins and scripting allows users to tailor the tool to their specific needs.

Wireshark is a versatile and powerful network analysis tool that provides comprehensive insights into network traffic. Whether you are a network administrator, security professional, or developer, Wireshark's robust features and capabilities make it an essential tool in your toolkit.

Key Features:

• Packet capture and analysis.
• Support for numerous network protocols.
• Real-time monitoring.
• Powerful filtering and search options.
• Colorized packet display.
• Packet decoding and reconstruction.
• Statistics and graphs.
• Protocol dissection and analysis.
• Extensibility and customization.
• Cross-platform compatibility.

• "On-the-wire" packet lengths are limited to 65535 bytes.
• "Follow TCP Stream" shows only the first HTTP request and response.
• Files with pcap-ng Simple Packet Blocks can’t be read.
• MPLS-over-PPP isn’t recognized.

• The Windows installer now uninstalls the previous version of Wireshark silently. You can still run the uninstaller manually beforehand if you wish to run it interactively.
• Expert information is now filterable when the new API is in use.
• The "Number" column shows related packets and protocol conversation spans (Qt only).
• When manipulating packets with editcap using the -C and/or -s options, it is now possible to also adjust the original frame length using the -L option.
• You can now pass the -C option to editcap multiple times, which allows you to chop bytes from the beginning of a packet as well as at the end of a packet in a single step.
• You can now specify an optional offset to the -C option for editcap, which allows you to start chopping from that offset instead of from the absolute packet beginning or end.
• "malformed" display filter has been renamed to "_ws.malformed". A handful of other filters have been given the "_ws." prefix to note they are Wireshark application specific filters and not dissector filters.
• The Kerberos dissector has been replaced with an auto generated one from ASN1 protocol description, changing a lot of filter names.
