Impossible to get an UDP connection

Postby ffelagund » 14 Jan 2019, 12:45

Hello,

I'm trying to get an UDP connection following the steps that I've found in the docs, but I'm unable to.
Here is what I did:
a) I've set up the server in the Admin Tool for listening to the address 0.0.0.0:9933 (TCP) and 0.0.0.0:9999 (UDP)
b) I've successfully compiled and got a normal TCP connection in the SpaceWar demo.
c) Following the documentation steps, I've added the following line just after the LOGIN one:
getSmartFox()->AddEventListener(SFSEvent::UDP_INIT, boost::shared_ptr<EventListenerDelegate> (new EventListenerDelegate(LoginScene::onUDPInit, (unsigned long long)this))); and wrote a simple onUDPInit function that just checks the operation status.
d) Called InitUD(); (no parameters) in the onLogin callback
e) In the ServerConnector I wrote the following code (replacing m_smartFoxServer->Connect("127.0.0.1, 9933);):

Code: Select all

boost::shared_ptr<Sfs2X::Util::ConfigData> data(new Sfs2X::Util::ConfigData);
   #define SERVER_IP "192.168.0.154"
   //#define SERVER_IP "127.0.0.1"
   data->Host(SERVER_IP);
   data->Port(9933);
   data->UdpHost(SERVER_IP);
   data->UdpPort(9999);
   data->Debug(true);
   data->Zone("SpaceWar");
   m_smartFoxServer->Connect(data);


Server's log for the loging attempt that is failing is the following:

Code: Select all

14:04:00,660 INFO  [SocketReader] sessions.DefaultSessionManager     - Session created: { Id: 2, Type: DEFAULT, Logged: No, IP: 192.168.0.89:51397 } on Server port: 9933 <---> 51397
14:04:05,412 INFO  [SFSWorker:Ext:4] api.SFSApi     - User login: { Zone: SpaceWar }, ( User Name: 36, Id: 1, Priv: 0, Sess: 192.168.0.89:51397 ) , Type: C++ API


My Smartfox server is running on a linux machine and in the same network. No fiweralls neither proxies are between the client and the server.

What is happening is that inside the InitUDP, the operation takes ages (say minutes) and sometimes the process ends with a stack overflow crash, or the server drops the session

Code: Select all

14:06:11,886 INFO  [SocketReader] sessions.DefaultSessionManager     - Session removed: { Id: 2, Type: DEFAULT, Logged: Yes, IP: 192.168.0.89:51397 }
14:06:11,887 INFO  [SFSWorker:Sys:1] api.SFSApi     - User disconnected: { Zone: SpaceWar }, ( User Name: 36, Id: 1, Priv: 0, Sess: 192.168.0.89:51397 ) , SessionLen: 126475, Type: C++ API


I've checked the server logs and it seems that the udp socket is connectly bound, so I have no clue about what I could be doing wrong.

Any help would be appreciated.
Thanks!

Hello,
Server's log for the loging attempt that is failing is the following:

Code: Select all

14:04:00,660 INFO  [SocketReader] sessions.DefaultSessionManager     - Session created: { Id: 2, Type: DEFAULT, Logged: No, IP: 192.168.0.89:51397 } on Server port: 9933 <---> 51397
14:04:05,412 INFO  [SFSWorker:Ext:4] api.SFSApi     - User login: { Zone: SpaceWar }, ( User Name: 36, Id: 1, Priv: 0, Sess: 192.168.0.89:51397 ) , Type: C++ API


the logs you have reported don't seem to indicate any failures. If the UDP connection fails you will see it from client side, in the SFSEvent.UDP_INIT.

It sounds pretty strange that it's taking so long for the connection in a local network. The long time actually suggests a firewall in between, even if you reported there should be none.

To check your network is fine I suggest this test:

1) stop SFS2X
2) on the Linux machine running SFS2X execute this -> nc -ul 9999 (listens on UDP 9999)
3) on the client machine run this command -> echo -n "Hello World" >/dev/udp/<server-ip>/9999

You should immediately receive the "Hello World" message on the Linux box.

Let us know.

Just to make things cleaner and easier to diagnose, I've just configured a local Smartfox server. Server side I got the same logs:

Client side, I still have a crash, in a different part of the code but always inside InitUDP. This is the callstack

I did not the netcat test because the client is a Windows machine (a Visual Studio project) and getting netcat there is not straigthforward.

It also happens that if the client doesn't crash, the session is dropped in the following way;

Edit: I've downloaded a nc for windows and the message reachs the remote machine with no delay.

Re: Impossible to get an UDP connection

Postby Lapo » 14 Jan 2019, 15:38

This is kind of confusing.
If the client crashes --> ok, since it's dead the server detects the disconnection and that's it. However in the logs you have posted, where the client does not crash, there is no login request.

So, I am a little confused on the tests you're doing. It looks like they are not the same every time.
As far as I understand it the client is supposed to :

-> connect
-> login
-> init udp, on positive login response
-> join etc...

Can you clarify how the test works? Does it always crash on UDP init?
What OS/environment are you using for the C++ client?
Are you using the latest C++ API? (1.7.5)

Thanks

Ok,

Client:
Windows 10
Visual Studio 2017 (vstoolkit 140)
Client API version: 1.7.5

Connection Process:
SpaceWar login process, almost unmodified but with the following changes

Code: Select all

#define SERVER_IP "127.0.0.1"
#define SERVER_PORT 9999
void ServerConnector::connect()
{
   boost::shared_ptr<Sfs2X::Util::ConfigData> data(new Sfs2X::Util::ConfigData);
   data->Host(SERVER_IP);
   data->Port(9933);
   data->UdpHost(SERVER_IP);
   data->UdpPort(SERVER_PORT);
   data->Debug(true);
   data->Zone("SpaceWar");
   m_smartFoxServer->Connect(data);
}

void LoginScene::setAppDelegate(AppDelegate * appDelegate)
{
   BaseScene::setAppDelegate(appDelegate);

   getSmartFox()->AddEventListener(SFSEvent::LOGIN, boost::shared_ptr<EventListenerDelegate>(new EventListenerDelegate(OnLogin, (unsigned long long)this)));
   getSmartFox()->AddEventListener(SFSEvent::LOGIN_ERROR, boost::shared_ptr<EventListenerDelegate>(new EventListenerDelegate(OnLoginError, (unsigned long long)this)));
   [b]getSmartFox()->AddEventListener(SFSEvent::UDP_INIT, boost::shared_ptr<EventListenerDelegate> (new EventListenerDelegate(LoginScene::onUDPInit, (unsigned long long)this)));[/b]
}

void OnLogin(unsigned long long context, boost::shared_ptr<BaseEvent> evt) {
   LoginScene *loginScene = (LoginScene *)context;
   AppDelegate* appDelegate = loginScene->getAppDelegate();
   boost::shared_ptr<Sfs2X::SmartFox> sfs = loginScene->getSmartFox();

   CCLOG("Enable lag monitor");
   sfs->EnableLagMonitor(true, 1, 5);
   boost::shared_ptr<std::string> version = sfs->Version();
   sfs->InitUDP();
   .
   .
   .
   .
}


Those are all the changes I've made to the SpaceWar sources and in the Admin Tool.

Now, what is happening, is that when InitUPD is called, it spends a lot of minutes and finally it gets disconnected from the server (the session is lost) but the game thinks it's still connected and is sending messages to the server, that eventually fails because there is no session established between the client and the server. I don't care very much about this error, as I understand SpaceWar is just an example of how to use the API and not all error paths are controlled. What is giving me headaches is the fact that the session is lost after a lot of minutes and I can't get a working UPD connection (but a normal TCP connection works without problems)

This is the server log after the error have happened

As you can see, the user loses its session and gets disconnected (although later the game is receiving onConnected events, that why it is creating and removing sessions but as the user is logged out they fail. As said, this error doesn't concerns to me as this should be caused by the SpaceWar sample, after a connection error that wasn't correctly handled)

The question is, why can't I get a working UDP connection?

Thanks!

Hi,
I was able to reproduce the problem locally on Mac, though Wireshark seems to show a correct UDP handshake, so I am not too sure what the problem might be at the moment. I've forwarded the issue to our C++ developer.

I'll keep you updated.

Thanks
Lapo

Unfortunately no. Our C++ developer is out of office until the 25th.
We'll get back to you as soon as possible.

Hi Jacobo,
first of all let me apologize for the delay in writing this answer: unfortunately I was out of office last week.

I have investigated the issue and at the moment I have a workaround to suggest you.
It is a temporary solution that I hope will work around the error while I will look for a well-made solution

Please try these steps:
  • We want to add a new public variable as a member of the LoginScene class
    So, edit the LoginScene.h file and add this public member

    Code: Select all

          std::thread *t1;


    You will have

    class LoginScene : public BaseScene
    {
    ...
    public:
    std::thread *t1;
    ....
    };
  • We want to call InitUDP in a different thread context.
    So, edit the OnLogin method contained in the LoginScene.cpp file to replace the statement

    Sfs->InitUDP()

    with

    Code: Select all

          loginScene->t1 = new std::thread(&ServerConnector::AsyncInitUdp, ServerConnector::GetInstance());


    You will have

    void OnLogin(unsigned long long context, boost::shared_ptr<BaseEvent> evt)
    {

    // Sfs->InitUDP()
    loginScene->t1 = new std::thread(&ServerConnector::AsyncInitUdp, ServerConnector::GetInstance());

    }
  • We want to declare a new public method (AsyncInitUdp) that performs the call to InitUDP
    So, edit the ServerConnector.h file to add the declaration of a new public method

    Code: Select all

       void AsyncInitUdp();


    You will have

    class ServerConnector
    {
    ...
    public:
    void AsyncInitUdp();
    ...
    }
  • We want to implement a new public method (AsyncInitUdp) that performs the call to InitUDP
    So, edit the ServerConnector.cpp file to add the implementation of a new method

    Code: Select all

       void ServerConnector::AsyncInitUdp()
       {
               m_smartFoxServer->InitUDP();
       }

Let me know if this workaround resolves the error
Thanks
Massimo
