dumpcap:tldr:c6928
This command utilizes the tool "dumpcap" to capture network traffic from a specified network interface and save it to a pcapng file. Let's break down the different components:
-
dumpcap
: It is a command-line tool included in the Wireshark package. It allows you to capture network traffic on a specified interface and save it in various file formats. -
--interface ${1}
: This flag is used to specify the network interface from which the network traffic will be captured.${1}
represents a parameter passed to the command when it is executed. It is expected that the user specifies the desired network interface as the value for${1}
. -
-w ${path-to-output_file-pcapng}
: This flag specifies the output file for saving the captured network traffic.${path-to-output_file-pcapng}
represents another parameter that should be provided when executing the command. It should be replaced with the desired file path and name where you want to save the captured traffic in pcapng format.
So, when you run the command, it will use "dumpcap" to capture network traffic from the specified network interface (which is passed as a parameter) and save it to the specified file location (another parameter), using the pcapng file format.
