Wireshark is a free and open source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Wireshark provides a dissector for CIGI packets. As of October 2016, “The CIGI dissector is fully functional for CIGI version 2 and 3. Version 1 is not yet implemented.” [11]
A capture file saved in the format that libpcap, WinPcap, and Npcap use can be read by applications that understand that format, such as tcpdump, Wireshark, CA NetMaster, or Microsoft Network Monitor 3.x.

Free and open-source software portal; Scapy is a packet manipulation tool for computer networks, [3] [4] originally written in Python by Philippe Biondi. It can forge or decode packets, send them on the wire, capture them, and match requests and replies.
A protocol analyzer is a tool (hardware or software) used to capture and analyze signals and data traffic over a communication channel.Such a channel varies from a local computer bus to a satellite link, that provides a means of communication using a standard communication protocol (networked or point-to-point).
Wireshark – supports interactive collection of network traffic and non real-time analysis of data packet captures (*.pcap). PhotoRec – supports recovery of lost files from hard disk, digital camera and optical media. Fsstat – displays file system statistical information about an image or storage object.
