Question

ubuntu

How to capture all incoming and outgoing traffic in Linux Ubuntu, all logs completely.

Answer 1

wireshark - graph. utility for online proceedings in the stream.
For a "clean" copying of the stream to a file, I advise tcpdump, they can even sniff traffic on the router under openwrt.
sudo tcpdump -i eth0 -w raw_dump.pcap
and the resulting file can already be slipped into wireshark for investigations of who sent whom where ...
see what data exchange systems are plugged into your laptop and look for sniffer systems for them.
absolute means do not exist in nature.
