look at documentation to the luasocket, esp. the part about tcp [1]
it says:

    socket.tcp()
   Creates and returns a TCP master object. A master object can be
transformed into a server object with the method listen (after a call
to bind) or into a client object with the method connect. The only
other method supported by a master object is the close method.

so you just need to say the master-object `tcp` it's a server.
