$ sudo tcpflow -o tcpflow_files $ sudo ls -l tcpflow_files The -o option can help you specify the output directory where the transcript files will be written. There is also an XML report generated, which contains information about the program such as how it was compiled, and the computer it was run on and a record of every tcp connection.Īs you may have noticed, tcpflow stores the transcript files in the current directory by default. From the output above, you can see that there are three transcript file, which indicate tcpflow in two opposite directions, where the source IP in the first file and the destination IP in the second file and vice versa. Now let’s do a directory listing to see if tcp flow has been captured in any files. $ sudo tcpflowīy default tcpflow stores all captured data in files that have names in the form (this may be different if you use certain options such as timestamp). Note that it listens on the active network interface (for instance enp0s3).

$ sudo apt install tcpflow #Debian/UbuntuĪfter installing tcpflow, you can run it with superuser privileges, otherwise use the sudo command. TCPflow is available in the official repositories of mainstream GNU/Linux distributions, you can install it using your package manager as shown. There are many use cases for tcpflow which include to understand network packet flows and also supports for performing network forensics and divulge the contents of HTTP sessions. Its feature set includes an advanced plug-in system for decompressing compressed HTTP connections, undoing MIME encoding, or invoking third-party programs for post-processing and much more. The only difference is that tcpflow puts all the TCP packets into order and assembles each flow in a separate file (a file for each direction of flow) for later analysis. It supports the same powerful filtering expressions supported by its counterpart. It is actually a tcpdump-like tools as it processes packets from the wire or from a stored file.

TCPflow is a free, open source, powerful command line based tool for analyzing network traffic on Unix-like systems such as Linux.
