Socks5 not working on 4.1.8

Question asked by Andreas Mennel on Oct 24, 2016

I have a server running ons aws which is working well. Furthermore I have a smack 4.1.8 client on a android device  and one more on a simple java applicaiton also running 4.1.8.

I would like to use socks5 for file transfer which I enabled on my server.


On my android device I just do some sending so there is only this code:

Socks5BytestreamManager manager = Socks5BytestreamManager.getBytestreamManager(connection);
        Socks5BytestreamSession session = manager.establishSession("receiver@myserver/Smack");
        File file = new File(fileToSend);

        ObjectInputStream ois = new ObjectInputStream(new FileInputStream(file));
        OutputStream oos = session.getOutputStream();

        IOUtils.copy(ois, oos);

    } catch (XMPPException | IOException | InterruptedException | SmackException e)


The java application gets configured like this:

 socks5BytestreamManager = Socks5BytestreamManager.getBytestreamManager(xmppConnection);
    socks5BytestreamManager.addIncomingBytestreamListener(new IncomingByteStreamListener());


and the code for receiving is this:

try {
                Socks5BytestreamSession socks5BytestreamSession = request.accept();
                InputStream ois = socks5BytestreamSession.getInputStream();
                File file = new File(OutputHelper.DirectoryPath + "test");
                FileOutputStream fos = new FileOutputStream(file);

                IOUtils.copy(ois, fos);

            } catch (InterruptedException | XMPPException.XMPPErrorException | SmackException | IOException e) {


When I try to send the file, I get the following message/error from the java application:


04:25:22 PM RECV (0): <iq from='sender@myserver/Smack' to='receiver@myserver/Smack' xml:lang='en' id='9Zjua-31' type='set'><query xmlns='' sid='js5_4232423505050900029' mode='tcp'><streamhost jid='sender@myserver/Smack' host='fe80::5054:ff:fe12:3456%eth0' port='032777'/><streamhost jid='sender@myserver/Smack' host='' port='032777'/><streamhost jid='proxy.myserver' host='' port='032777'/></query></iq>

What am I missing? I have spent much time on google to solve this issue but couldn't find anything usefull...


I would go about the


item-not-found xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'


part of the error, but so far I could not figure out anything.


Thanks for your help!
