networking - Socat: send a UDP broadcast from stdin, but …

socat et al.: run a command when incoming connection is received
2023年9月6日 · Yes, that's the whole point. Stdout goes to the TCP client. If you wanted the stdout of the command/shell to go to socat's stdout, you could add ,fdout=333 for instance to tell socat that's what's written on fd 333 instead that goes to the client (and fd 1 (stdout) is left alone).

socat - How to create a socket forwarder as a server? - Unix
2019年7月8日 · I found socat is able to forward socket ports in general: socat tcp-l:8080,fork,reuseaddr tcp:127.0.0.1:12345 This forwards the "official" port 8080 to internal socket port 12345 successfully. BUT: my problem is that clients should be able to connect to port 8080 even if internal port 12345 is currently unavailable.
Redirect stdin and stdout to ports - Unix & Linux Stack Exchange
