# Simple tcp server using netcat
# - depending on the netcat version either use nc -l 5555 or nc -l -p 5555
# - verify with `telnet locahhost 5555`
# - quit the telnet with `ctrl-]` and then type quit
# - the while loop is there so reopen the port after a client has disconnected
# - supports only one client at a time
PORT=5555;
while :; do nc -l -p $PORT | tee output.log; sleep 1; done

On OSX this is while :; do nc -l localhost $PORT | tee output.log; sleep 1; done (or use brew for conventional unix syntax)
