socat: Show incoming connections

  • 772

I am slightly going mad. Even if I call socat like this:

socat -vvvv tcp4-listen:9000 tcp4-listen:9001

it works perfectly, but doesn't inform me about incoming TCP connections! Is there an additional verbosity option that makes socat show this information, something like

Connection from XYZ

Can't be such a special function, or can it?

networking unix tcp socat

    By old habit I am just used to grouping arguments together like -dddd for more verbose debugging, but when I actually tried what the manpage said (-d -d) it worked just fine. For logging connections, just do:

    socat -d -d tcp4-listen:9000 tcp4-listen:9001
