Hallo,
ich versuche gerade einen TCP Server aufzusetzen.
das funktioniert auch, aber wie beende ich den Server?
Beim Stoppen des Scripts und Neustart bekomme ich

Error: listen EADDRINUSE: address already in use :::85

hier mal mein script:

var net = require('net');
// Configuration parameters
var HOST = 'localhost';
var PORT = 85;
// Create Server instance 
var server = net.createServer(onClientConnected);  
 
server.listen(PORT,  function() {  
  console.log('server listening on '+ server.address(0));
});
server.on('error', function (e) {
  if (e.code == 'EADDRINUSE') {
    console.log('Address in use, retrying...');
    setTimeout(function () {
      server.close();
      console.log(server.connections)
      server.listen(PORT, HOST);
    }, 1000);
  }
});
 
function onClientConnected(sock) {  
  var remoteAddress = sock.remoteAddress + ':' + sock.remotePort;
  console.log('new client connected:'+ remoteAddress);

  sock.on('data', function(data) {
    console.log('Says:'+ data);
    
    //sock.write(data);
    setze_Input_state(data);
    //sock.write(' exit');
  });
  sock.on('close',  function () {
    console.log('connection from %s closed'+ remoteAddress);
  });
  sock.on('error', function (err) {
    console.log('Connection %s error: %s'+ remoteAddress+ err.message);
  });
    // close connection if script stopped
  onStop(function (callback) {
   // if (client) {
        // close connection
        sock.end();
        //sock.unref();
        //server.destroy();
            console.log('Connection DESTROYED');
   // }
    callback();
   }, 2000 /*ms*/);
};

wie kann ich den Server beenden und neu Starten??

@stoffel67 said in nodejs net server beenden:
Fehler gefunden:

      // close connection
        server.close();
        //sock.unref();

ich muss den Server beenden, nicht den "socket":relieved:
