To start tcpdump, use the following command syntax: tcpdump -ni -W -C -w.Select “Show Packet in New Window” from the drop-down menu.Open the “View” tab from the toolbar above.Select the packet from the list with your cursor, then right-click.Once the packets are captured, Wireshark organizes them in a detailed packet list pane that’s incredibly easy to read. How do you read packet capture in Wireshark?

It saves the file in a pcap format, that can be viewed by tcpdump command or an open-source GUI-based tool called Wireshark (Network Protocol Analyzer) that reads tcpdump pcap format files. Tcpdump also gives us an option to save captured packets in a file for future analysis.

All you have to do is use the “-r” option with tcpdump command and specify the path of the file you want to read. The “-r” option lets you read the output of a file. The “-w” option lets you write the output of tcpdump to a file which you can save for further analysis. How do I search for a file in Wireshark?.How do I capture a TCP packet in Wireshark?.What should I look for in Wireshark capture?.How do you decrypt packets in Wireshark?.How do I open a pcap file in Notepad ++?.How can I read pcap files without Wireshark?.What is the difference between tcpdump and Wireshark?.How do you read packet capture in Wireshark?.This tool will be there for almost all Un*xen you will find, TShark might not. If you do a lot of network capturing it is well worth the effort to learn all the command line switches to TcpDump for the same reason learning VI is useful.

TcpDump lives at TcpDump is also the place where LibPcap lives LibPcap is the standard API and CaptureFile format used by Wireshark and TShark as well as many many other tools. TcpDump is standard and distributed with many many Un*x-like operating systems (except the one coming with the tool you will find by googling for 'The Interface From Hell')
