How to listen for multiple tcp connection using nc
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.
