In Linux, tcpdump by default saves captured packets in the current working directory, using “tcpdump” as the filename prefix followed by the date and time as the filename suffix.

To check the default location where tcpdump saves files, you can use the following command:

tcpdump -w filename

This will create a file named “filename” in the current working directory and write the captured packets to that file.

If a file name is not specified, tcpdump will save files using the default format “tcpdump-yyyymmdd-hhmmss”. You can use the ls command to view the files in the current working directory and locate the files starting with “tcpdump”.

If you wish to save the captured packets to a specific location, you can specify the full file path in the command, for example:

tcpdump -w /path/to/filename

This will create a file named “filename” in the /path/to/directory and write the captured packets to that file.
