Tcpdump Tutorial

Development

This is an excellent, short intro to the command-line network analyzer, tcpdump: https://danielmiessler.com/study/tcpdump/

To install tcpdump, on Debian-family distros:

    $ sudo apt install tcpdump

Now try this, but maybe put on sunglasses first :slight_smile:

    $ sudo tcpdump -nnvvXSs 0

I actually think this is the way ahead in collecting stats on the SAFE-protocol networks; just got to devise the right filters.

EDIT: Changed 1514 (biggest ordinary frame) to 0 (catch every frame regardless of size) in order to catch jumbo frames.
