unable to send file transfer even if disableSocks5 is YES

Hi Jonathon Staff,

i have been trying to send file by disabling SockS5.

below is the code for button action

- (IBAction)btnTransferClicked:(id)sender
{
  if (!_fileTransfer) {
    _fileTransfer = [[XMPPOutgoingFileTransfer alloc]
                                               initWithDispatchQueue:dispatch_get_main_queue()];
    [_fileTransfer activate:[self appDelegate].xmppStream];
      _fileTransfer.disableSOCKS5 = YES;

    [_fileTransfer addDelegate:self delegateQueue:dispatch_get_main_queue()];

  }
    UIImage *imagePic = [UIImage imageNamed:@"defaultPerson.png"];
    NSData *dataPic =  UIImagePNGRepresentation(imagePic);

  NSError *err;
  if (![_fileTransfer sendData:dataPic
                         named:@"defaultPerson.png"
                   toRecipient:[XMPPJID jidWithString:@"venu@xx.in/Smack"]
                   description:@"Baal's Soulstone, obviously."
                         error:&err]) {
    DDLogInfo(@"You messed something up: %@", err);
  }
}

and below is the console logs

Please help me .

What device (I assume iOS or OS X) are you sending from and what are you sending to? It looks like you're using Smack; does this mean an Android device is receiving?

The error you're receiving is caused by a timeout (Outgoing file transfer failed because: Timeout waiting for recipientdisco#inforesponse.), indicating that the recipient doesn't properly handle an incoming request for disco#info.

yes,It works fine ,just set

xmppIncomingFileTransfer.disableIBB = NO;
xmppIncomingFileTransfer.disableSOCKS5 = YES;

Sorry I can not understand. I managed successfully from iphone client to spark. Unfortunately I can not send files from iphone to iphone. here is the error:

Error Domain = XMPPOutgoingFileTransferErrorDomain Code = -1 "Unable to send SI offer; the recipient does not have the required features." UserInfo = {0x8388b8e0 NSLocalizedDescription = Unable to send SI offer; the recipient does not have the required features.}

This and my Delegate class. As you can see I have included the code for file transfer. I think I have taken all the steps correctly. Unfortunately, the file transfer will not work. What am I doing wrong? thank you.

 * Allows a delegate to hook into the TLS handshake and manually validate the peer it's connecting to.
 *
 * This is only called if the stream is secured with settings that include:
 * - GCDAsyncSocketManuallyEvaluateTrust == YES
 * That is, if a delegate implements xmppStream:willSecureWithSettings:, and plugs in that key/value pair.
 *
 * Thus this delegate method is forwarding the TLS evaluation callback from the underlying GCDAsyncSocket.
 *
 * Typically the delegate will use SecTrustEvaluate (and related functions) to properly validate the peer.
 *
 * Note from Apple's documentation:
 *   Because [SecTrustEvaluate] might look on the network for certificates in the certificate chain,
 *   [it] might block while attempting network access. You should never call it from your main thread;
 *   call it only from within a function running on a dispatch queue or on a separate thread.
 *
 * This is why this method uses a completionHandler block rather than a normal return value.
 * The idea is that you should be performing SecTrustEvaluate on a background thread.
 * The completionHandler block is thread-safe, and may be invoked from a background queue/thread.
 * It is safe to invoke the completionHandler block even if the socket has been closed.
 *
 * Keep in mind that you can do all kinds of cool stuff here.
 * For example:
 *
 * If your development server is using a self-signed certificate,
 * then you could embed info about the self-signed cert within your app, and use this callback to ensure that
 * you're actually connecting to the expected dev server.
 *
 * Also, you could present certificates that don't pass SecTrustEvaluate to the client.
 * That is, if SecTrustEvaluate comes back with problems, you could invoke the completionHandler with NO,
 * and then ask the client if the cert can be trusted. This is similar to how most browsers act.
 *
 * Generally, only one delegate should implement this method.
 * However, if multiple delegates implement this method, then the first to invoke the completionHandler "wins".
 * And subsequent invocations of the completionHandler are ignored.

I do got same error info:

Hope... one of us will update with 'Solution' ASAP.

:( Are five days that I'm going crazy to fix this error with no results. I really hope that some user can give a solution. Thank You.

What are the JIDs for each device you're sending to and receiving from?

Hello Jonstaff,

Sender JID : Sender-username@domain/resource Receiver JID : Receiver-username@domain/resource

Resource : taken from full JID in presence delegate

e.g: test123@192.165.4.78/237956891081628672871

Thanks in advance

I need the actual JIDs you're using in the failed transfer, not a description of how they work.

Sender JID: 2000530038@192.168.XX.XX/4184529043698432067

Receiver JID: 918790013636@192.168.XX.XX/23749801272032817639

Where , 192.168.XX.XX is local host

these are my logs:

I wanted to inform you guys that I have succeeded. After 10 days of work I have reached this conclusion. I deleted my class AppDelegate taken from the sample project framework xmmpframework. Right now I'm working with the class AppDelegate Project File-Transfer-Demo and everything works. I really hope that in the next release of the framework XMPPFRAMEWORK in the sample project for IOS will also include File-Transfer-Demo. Thanks for the support.

你好jonstaff，我在传输文件中一直返回失败，麻烦你帮我看下是什么情况，多谢。这是我的代码：

XMPPJID *jid = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@%@/Smack",recipient,ServerName]];
if (!_fileTransfer) {

    _fileTransfer = [[XMPPOutgoingFileTransfer alloc]
                     initWithDispatchQueue:dispatch_get_main_queue()];
    _fileTransfer.disableSOCKS5 = YES;
    [_fileTransfer activate:_xmppStream];
    [_fileTransfer addDelegate:self delegateQueue:dispatch_get_main_queue()];
}
NSError *err;
if (![_fileTransfer sendData:fileData
                       named:fileName
                 toRecipient:jid
                 description:description
                       error:&err]) {
    //不能传输
    NSLog(@"不能传输");
}

返回的错误信息是： Error Domain = XMPPOutgoingFileTransferErrorDomain Code = -1 "Unable to send SI offer

你好。我的中文不好，所以请原谅我。在哪里说 Error Domain = XMPPOutgoingFileTransferErrorDomain Code = -1 "Unable to send SI offer ? 还有什么说？这个错误不是完整。

你好jonstaff，很高兴收到你的回复，我的完整错误信息是：Error Domain=XMPPOutgoingFileTransferErrorDomain Code=-1 "Unable to send SI offer; the recipient doesn't have the required features." UserInfo=0x15e59910 {NSLocalizedDescription=Unable to send SI offer; the recipient doesn't have the required features.} 其中，我要传输到的Jid信息是13430420870@win-qlsnkq93bfg/Smack。再次感谢你的回复，希望能和你有更多的交流，我来自中国深圳。

Hello Everybody, since two weeks i'm facing this problem when i trying to send files. Domain=XMPPOutgoingFileTransferErrorDomain Code=-1 "Unable to send SI offer; the recipient doesn't have the required features." UserInfo=0x15e59910 {NSLocalizedDescription=Unable to send SI offer; the recipient doesn't have the required features.} Does anyone find how to fix this error ? I need some help please...

copied by venkateswarlunp. it work for me. Sender JID : Sender-username@domain/resource Receiver JID : Receiver-username@domain/resource

Resource : taken from full JID in presence delegate

I got it working this way-

Inside setupStrem method, set up the incoming end like this -

xmppIncomingFileTransfer = [[XMPPIncomingFileTransfer alloc] init];
xmppIncomingFileTransfer.disableIBB = NO;
xmppIncomingFileTransfer.disableSOCKS5 = NO;

[xmppIncomingFileTransfer   activate:xmppStream];

[xmppIncomingFileTransfer addDelegate:self delegateQueue:dispatch_get_main_queue()];

Implement the incoming end delegate methods-

- (void)xmppIncomingFileTransfer:(XMPPIncomingFileTransfer *)sender
                didFailWithError:(NSError *)error
{
    DDLogVerbose(@"%@: Incoming file transfer failed with error: %@", THIS_FILE, error);
}

- (void)xmppIncomingFileTransfer:(XMPPIncomingFileTransfer *)sender
               didReceiveSIOffer:(XMPPIQ *)offer
{
    DDLogVerbose(@"%@: Incoming file transfer did receive SI offer. Accepting...", THIS_FILE);
    [sender acceptSIOffer:offer];
}

- (void)xmppIncomingFileTransfer:(XMPPIncomingFileTransfer *)sender
              didSucceedWithData:(NSData *)data
                           named:(NSString *)name
{
    DDLogVerbose(@"%@: Incoming file transfer did succeed.", THIS_FILE);

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                         NSUserDomainMask,
                                                         YES);
    NSString *fullPath = [[paths lastObject] stringByAppendingPathComponent:name];
    [data writeToFile:fullPath options:0 error:nil];

    DDLogVerbose(@"%@: Data was written to the path: %@", THIS_FILE, fullPath);
}

Incoming files will be written to the documents directory, you can update UI when it is done.

On the sending side-

if (!_fileTransfer) {
        _fileTransfer = [[XMPPOutgoingFileTransfer alloc] initWithDispatchQueue:dispatch_get_main_queue()];

        AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

        [_fileTransfer activate:appDelegate.xmppStream];
        _fileTransfer.disableIBB = NO;
        _fileTransfer.disableSOCKS5 = NO;

        [_fileTransfer addDelegate:self delegateQueue:dispatch_get_main_queue()];
    }

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                         NSUserDomainMask,
                                                         YES);
    NSString *fullPath = [[paths lastObject] stringByAppendingPathComponent:filename];
    NSData *data = [NSData dataWithContentsOfFile:fullPath];

    NSError *err;
    if (![_fileTransfer sendData:data
                           named:filename
                     toRecipient:[XMPPJID jidWithString:self.contact.primaryResource.jidStr]
                     description:@"Baal's Soulstone, obviously."
                           error:&err]) {
        DDLogInfo(@"You messed something up: %@", err);
    }

Implement the outgoing delegate methods -

- (void)xmppOutgoingFileTransfer:(XMPPOutgoingFileTransfer *)sender
                didFailWithError:(NSError *)error
{
    DDLogInfo(@"Outgoing file transfer failed with error: %@", error);

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error"
                                                    message:@"There was an error sending your file. See the logs."
                                                   delegate:nil
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
    [alert show];
}

- (void)xmppOutgoingFileTransferDidSucceed:(XMPPOutgoingFileTransfer *)sender
{
    DDLogVerbose(@"File transfer successful.");

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Success!"
                                                    message:@"Your file was sent successfully."
                                                   delegate:nil
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
    [alert show];
}

Note that the disableIBB and disableSOCKS5 should match at both ends. If the problem still exists, go to XMPPOutgoingFileTransfer.m and then to the method-

(void)handleRecipientDiscoInfoQueryIQ:(XMPPIQ )iq withInfo:(XMPPBasicTrackingInfo )info

Then put a NSLOG/Breakpoint at this line -

hasSOCKS5 = hasSI && hasFT && hasSOCKS5;
hasIBB = hasSI && hasFT && hasIBB;

Both values should become TRUE when sending a file. Check which one is FALSE (causing the error), you will get an idea why the incoming end is sending FALSE instantly. Try to fix that.

the sender in the wifi , the receive in 4G send file failed. it's the outcoming’s log and the receive's log below.

Is it possible to transfer offline file with above code.

above code is working for sending file when users are online.

I need to transfer when recipient is offline and once recipient is online, file should be fetch.

thanks in advance.
