Quick tip of the day.
Somehow you’ve got out of the script/server console (ctrl-Z instead of ctrl-C perhaps), but the server is still running, as you get this message if you try to start a new one
“TCPServer Error: Address already in use – bind(2)”
type “jobs” and you will see it there. (should be number 1)
type “fg 1” to bring the server back and then if you want, ctrl-C to quit it
