Hey ,&nbsp;

I am creating an application using juce with embedded webserver , so i am&nbsp;scanning for open ports on machine and launch webserver on it.&nbsp;I am doing this but doesnt seem to be working :

&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;bool connectionMade = false;  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;while (( !connectionMade) && (\_openPort \< 65535))  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;{ &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ScopedPointer\<StreamingSocket\>&nbsp; \_socket = new StreamingSocket();

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;\_socket-\>createListener(\_openPort);

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;\_socket-\>connect("localhost",\_openPort,3000)

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;connectionMade = \_socket-\>bindToPort(\_openPort);

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if(connectionMade == false)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp;\_openPort++;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; \_socket-\>close();

&nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; }

&nbsp;

Also tried using the UDP same problem , it returns false&nbsp;connect or bind, using the latest libraries:

while (( !connectionMade) && (\_openPort \< 65535))  
&nbsp;&nbsp; &nbsp;{ &nbsp; &nbsp; &nbsp;  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp; ScopedPointer\<DatagramSocket\>&nbsp;&nbsp; &nbsp;\_socket = new DatagramSocket(\_openPort,false);  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp;\_socket-\>isLocal();  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp; //&nbsp;&nbsp; &nbsp;ScopedPointer\<DatagramSocket\> \_socket = new DatagramSocket(\_openPort); // chcekingfor open port  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp; //\_openPort = \_socket-\>getPort();  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; bool connectionMade = \_socket-\>isConnected();  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp; if(!connectionMade)  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; \_openPort++;  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp;\_socket-\>close();  
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp; \_ports = String(\_openPort);

&nbsp;}

&nbsp;

\_ports is what i pass to webserver .

What port number are you trying? Ports below 1024 have permissions problems. If you haven't already, try above 1024. 8080 is a common 'alternate webserver port' for this reason.

By the way, don't those function get stuck in infinite loops? Don't you mean 'if' not 'when' at the start of each?

I was trying above 1024 till 65535, The reason for searching open ports was in case the 8080 is acquired by some other webserver as i have embedded webserver in application . So was scaning port if its already occupied then use diff , else thsi one.&nbsp;Well in the end had to write native code.

Your scopedpointer is deleting your&nbsp;new StreamingSocket() every loop recursion, i can use websockets, but i must initiate them, and let them be... not killing them every loop !
