Port(7777) has been used sometime weird when use s5b to transfer file.

Port 7777 has been used sometime weird, means that I have two phones, one can open port 7777, another one can't. The reason is that maybe a third app installed on the phone is using the port(7777).

I have seen the snippet which coms from org.jivesoftware.smackx.bytestreams.socks5.Socks5Proxy.

if (getLocalSocks5ProxyPort() < 0) {     int port = Math.abs(getLocalSocks5ProxyPort());     for (int i = 0; i < 65535 - port; i++) {          try{               this.serverSocket = new ServerSocket(port + i);               break;          }          catch (IOException e) {               // port is used, try next one           }     }}else{     this.serverSocket = new ServerSocket(getLocalSocks5ProxyPort());}

these codes are from publicsynchronizedvoidstart() method. Found that it just to check if port has been using when localSocks5ProxyPort < 0,

when not, doesn't check weather port is already in use or not.

I changed the snippet to what it is below:

int port = Math.abs(getLocalSocks5ProxyPort());try{      this.serverSocket = new ServerSocket(port);}catch (IOException e) {     for (int i = 0; i < 65535 - port; i++) {          try{               this.serverSocket = new ServerSocket(port + i);               break;           }           catch (IOException e1) {                // port is used, try next one           }     }} if (this.serverSocket != null) {     this.serverThread = new Thread(this.serverProcess);     this.serverThread.start();}else{     LOGGER.log(Level.SEVERE, "couldn't setup local SOCKS5 proxy through all ports.");}

And then everything is ok, the next port will be found if current one is already in use.

Anyone has better idea for this will be appreciated!
