Anyone that uses netcat I could use a little help. I'v always used other tools for the jobs which worked just fine but thought I'd play with the utility of utilities. Anyway I want to listen and output to screen all inbound and outbound traffic of local machine.
I think I'm somewhat close but don't yet have it with the cmd of "nc -vv -l -p20-139". I've also tried a variation of it using "nc -vv -l -p20-139 > echo" and "nc -vv -l -p20-139 > echo "*.*.*.*" ". I get a listen prompt but no output to the screen and don't want to > to a file either. Just looking for realtime visual output.
