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. It is available under most of the Linux/Unix-based operating systems. Tcpdump is a most powerful and widely used command-line packets sniffer or package analyzer tool which is used to capture or filter TCP/IP packets that are received or transferred over a network on a specific interface.

When the network operation is complete, type ctrl-c on the Terminal to stop tcpdump.ДЄfter you have sent the problem.cap file to Kerio technical support, the file will be analyzed and you will be contacted regarding the results of the analysis.In our previous article, we have seen 20 Netstat Commands (netstat now replaced by ss command) to monitor or manage a Linux network.

Where is the IP address of the remote machine, such as 192.168.200.201

Open a Terminal session and log in as the 'root' user and, to start the network trace, type:.

Here are the basic steps for creating a trace using the tcpdump command line application: Tcpdump is the recommended application for generating network traces and is already installed on most Linux platforms.
