  • wireshark – Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Wireshark is very similar to tcpdump, but has a graphical front-end, plus some integrated sorting and filtering options.
    • TShark – TShark is a network protocol analyzer. It lets you capture packet data from a live network, or read packets from a previously saved capture file, either printing a decoded form of those packets to the standard output or writing the packets to a file. TShark’s native capture file format is pcapng format, which is also the format used by wireshark and various other tools.
    • Capinfos – Capinfos is a program that reads one or more capture files and returns some or all available statistics (infos) of each in one of two types of output formats: long or table.
  • netsniff-ng – netsniff-ng is a free Linux networking toolkit, a Swiss army knife for your daily Linux network plumbing if you will. Its gain of performance is reached by zero-copy mechanisms, so that on packet reception and transmission the kernel does not need to copy packets from kernel space to user space and vice versa.
  • Live HTTP headers – Live HTTP headers is a free firefox addon to see your browser requests in real time. It shows the entire headers of the requests and can be used to find the security loopholes in implementations.
