Hello, I've a lua script that use luasocket to listen to a specific port (3333). It work fine on the terminal but stop on ZBS. The script basically do this : local socket = require "socket" local server = assert(socket.bind("*", 3333)) function listen(server) local client = server:accept() client:settimeout(10) local line, err, partial = client:receive("*l") -- do something and store result if result then client:send(rslt.."\n") client:close() else client:close() end end while true do if listen(server) end On ZBS the process execution freeze actually when "receive()" is called : local line, err, partial = client:receive("*l") Is luasocket in conflict with ZBS ? Thanks, Renaud
