Discard UDP packet

[janheuninck]

Hi guys,

I think I discovered a bug: When the first user, after a server restart, enters a game room, he gets the Id 0



This doesn't give errors when the clients sends TCP messages to the server, but this error occurs when UDP messages are being sent:

Code: Select all

11:54:41,649 WARN  [SocketReader] protocol.SFSIoHandler     - Discard UDP packet from 127.0.0.1:60359, reason: User does not exist, id: -1 

When the user disconnects, and reconnects again, the error is gone and everything works fine. Is this a bug or am I doing something wrong?


Cheers
Jan

Since that is on the server side, I'll have to pass this on to appropriate people. Let me see what we can do.

HI,
can you please explain the steps to see the problem described in action?

[janheuninck]

Sorry for the late response, but I was on holiday.

The problem occurs the first time a user enters the game room and tries to send messages to the server via the UDP protocol. The server receives the messages, because it shows a warning for every message:

Code: Select all

11:54:41,649 WARN  [SocketReader] protocol.SFSIoHandler     - Discard UDP packet from 127.0.0.1:60359, reason: User does not exist, id: -1

The UDP protocol works fine though if messages are sent from the server to the client. The error disappears if the user disconnects and connects (and enters the room) again. The problem only occurs the very first time a client joins the room after a server restart.

This is the code I use to connect to a room and send UDP packages:

Code: Select all

- (void)onLogin:(SFSEvent *)evt
{
    // Initialize the UDP socket
    [smartFox initUDP:nil:-1];
}

Code: Select all

- (void)joinRoom:(NSString *)room
{
    [smartFox send:[JoinRoomRequest requestWithId:room]];
}

Code: Select all

- (void)send:(NSString *)msg useUDP:(BOOL)useUDP
{    
    // Create SFS Data object
    id data = [[SFSObject newInstance] autorelease];
    
    // Store data in SFS Data object
    // ...
    
    // Send via SFS
    [smartFox send:[ExtensionRequest requestWithExtCmd:CMD params:data room:[smartFox lastJoinedRoom] udp:useUDP]];
}

More logs:

It looks like the ports aren't the same (63807 <-> 49603)

We have verified that this is a bug in the iOS API and the issue has been fixed. It will be included in the next release. Thanks for reporting.

[janheuninck]

Any idea when you will release the new API that fixes this issue?


Thanks

[A51Integrated]

Sorry, no release date yet. We're waiting for a more substantial number of fixes to release a new version.

Hi,

I have been following this discussing since Jan posted it. I have the same problem. It's really annoying because I have to restart my SFServer all the time.
Could you release a next version of the OSX API in the near future? This bug has been reported on the 5th of April (almost a month and a half ago).
This subforum is not very active, there are not a lot of users that are posting bugs. If I have to wait for users to report bugs, I could be waiting for a very long time.

Thanks.
Jonas

The bug was fixed. A new version of the API can be downloaded here: http://www.smartfoxserver.com/download/sfs2x#p=updates (v1.0.5)

[janheuninck]

The bug was fixed. A new version of the API can be downloaded here: http://www.smartfoxserver.com/download/sfs2x#p=updates (v1.0.5)

Thanks, but it appears it is still version 1.0.4 that gets downloaded: SFS2X_API_ObjectiveC_v1.0.4

[Bax]

Sorry. Now it is fixed.

Hello,

We are using SFS2X version 2.0.1 and we are also facing Discard UDP packet issue. So I got to know from this post that it is fixed in this patch, downloaded the new patch from
http://www.smartfoxserver.com/download/sfs2x#p=updates
Installed the patch in a linux server (followed steps as instructed in the release notes).
After installing, restarted MMO server and tried connecting to it from a test app. It is not connecting and gives below error -
SocketPolicyClient1: Incoming GetPolicyStreamForIP
SocketPolicyClient1: About to BeginConnect to XXX.XXX.X.XX:9933
SocketPolicyClient1: About to WaitOne
SocketPolicyClient1: Socket connected
[SFS - ERROR] ## BlueBox Error: Invalid http session !
[SFS - ERROR] TCPSocketLayer: Connection closed by the remote side
Environments used –
Server – Linux Redhat
Client – Unity 3.5.2f2
After this error it will never reconnects again. What other settings do we need? How do I resolve this issue? We need to fix UDP discard packet issue.

Thanks in advance

The fix mentioned in this thread was for the iOS API - not the server itself. Try posting in the Unity / .NET forum and make sure you're using the latest client API as well.
