How to listen for multiple tcp connection using nc

Question

How to create a TCP connection using nc which listens to multiple hosts?

nc -l -p 12345

Answer 1

Simultaneous connections are not possible with netcat. You should use something like ucspi-tcp's tcpserver tool or leverage xinetd since you're on Linux.

Consecutive connections could be handled through a shell script that restarts netcat after it finishes.
