I am able to establish socket connection to a remote machine by first loadind the policy file. But the same thing is not working if i am trying to connect to the same remote machine & 443 as port No. In policy file the connection is allowed to all ports.
Is there any thing else to be done. I am geting sandbox violation error.
I don't need to deploy an HTTP server and all the connections are made on port 80, the default HTTP port, which is generally not blocked by firewall.Unfortunatly at the end of my work I realized that the flash socket component has some limitation on using port 80.[URL]As nobody is interested by this report, I now think that this limitation is done on purpose by Adobe. I don't know exactly why, may be to force to use their data service product.
I can understand that. But what I am hangry about is that nowhere in the documentation of the socket component there is an information about this limitation. I guess lot of people lost time trying to reach an unreachable goal ! And most of the time you find the problem at the end of the work because local connection is working ok on port 80.
Basically, Im learning how the socket class works in AS3, seems pretty simple, but I dont know what port to assign in the second connect() parameter, let say I wanna load a image from the web, what should I have to do to figure what port is the right one?
View 1 RepliesI'm trying to talk to a fully RESTful api of my own creation. The api is up and running but flash does not support PUT and DELETE, and does not recieve http status codes properly, plus a whole load of other issues with flashes anaemic http support.
To get around this I am trying to use as3httpclientlib. A 3rd party as3 http library, that uses socket connections to access the whole http protocol properly. It's a great library, unfortunately because it uses sockets flash requires implementation of the socket policy file, even though the access is all via port 80, the standard http port.

This has given me a real headache. I can't implement the port 843 policy server as the documentation suggests because it's out of my ability level i feel. Also when the client is running it may be behind a corporate firewall that doesn't allow 843 access, so serving the policy file via the standard port seems the way forward. This is where I am stuck.
The policy file documentation says this shouldn't matter as if you cant access 843 because of your firewall you'll be unable to access non standard ports anyway, but I am accessing standard ports, only via sockets instead of URLLoader.
In the root of my server I have placed the following policy file:
Code:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
[code]....
I'm working on a Flash/Facebook game. My swf and socket server are on different domains, so I have to use a socket policy file. According to Adobe, they have "filed with IANA, the Internet Assigned Numbers Authority, to reserve port 843 for the purposes of serving socket policy files." Unfortunately, my server has port 843 closed. I asked my server guy to open the port. Here's his reply:
[quote]One of the points Matt mentioned is even if we open that particular port how would you ensure the scores of people accessing this game from their schools, libraries or even people internal to OurCompany will have connectivity on the port. Let me explain, in order for traffic to flow on port 843 from the browser to the smart fox server, the users ISP also has to allow for that traffic to pass outbound from the users browser. It is possible that several users would not be able to run it, is that risk acceptable ?[/quote]
How common is it for ISPs to block port 843? I assumed that, since this is an Adobe standard, that ISPs would now have it open by default. What's the scoop?

There is a flash movie which is using flash.net.Socket to connect to a server. But there could be a situation when the server is not running, hence nothing is listening on the port socket is connecting to.
When I do "telnet hostname port" I get a fast connection refused error. But flash.net.Socket does not invoke any event (see below), but silently waits for socket timeout. For me it is important to reduce time needed to detect non-existing server as much as possible to be able to reconnect to another server in the cluster.
I've tried the following events, but to no avail:
close
connect
ioError
securityError
socketData
None of these is invoked in such situation.
Is there a way to detect that TCP connection has been refused using flash.net.Socket?
I would like Flash to reconnect to a socket if its connection is dropped. I am using the Socket class to establish a connection and then adding an Event.CLOSE listener to the socket.

I use a socket connection to share data between flash and VB. I check the connection in VB and send a message when my flash is connected. My VB tool then sends the data continuesly (about every 40 milliseconds or slower) to flash. Works fine. Now I have to send some data back from flash to VB. I can send the data without any errors in Flash but it never arrives in VB.

I am writing a peer-to-peer binary socket program. There are only two endpoints. One socket is listening on my laptop system. The other socket is broadcasting from my desktop system. I have a third program running on a hosted server, that is available to broker the connection between the two. My problem is that when the laptop and desktop are on the same network, they both have the same internet IP address but different intranet IPs, but when the laptop is on the road, then the IP addresses are different. In order to be truly peer-to-peer, I have to write it so that after the connection is established, that the two computers communicate directly between one another. How is this generally accomplished, when the two computers could potentially share the same IP address, if they are running on the same network?

View 1 RepliesI am trying to adapt an existing flash web chat application for the Android mobile phone and I am having this really annoying issue. The server is a custom based solution and can send back both binary messages or XML. So I can use either XMLSocket class or the Socket class to get data from the server. Everything works fine when deployed and I connect from the desktop but when I try it from the android mobile I get the infamous errors #2031, followed by #2048. Now the crossdomain.xml file is rock solid and works well for desktop. When the connect socket method runs I see that the server replies with the crossdomain file but I get the error when running on the mobile. Has anyone bumped into this? Is there some limitation from the mobile phone part. I wasn't able to find anything relevant for this issue, in terms of the phone not allowing Socket or SMLSocket connections
View 5 RepliesI am starting with a short introduction: I am currently working on a project, which involves a server application written in .NET (C#) and a flash gui app as client (standalone flash player 10 [code is written in Actionscript 3.0]). The server constantly sends bitmaps to the client (up to 30fps). The connection is established using binary sockets and data ist streamed to avoid socket open/close/reconnection problems.The bitmaps sent to the client are marked with begin- and end-tags. A length field was added as well, to optimise the following parsing process. The client buffers the received data up to the point where an end-tag is found. The client reassambles the bitmaps on the screen by parsing the current buffer. Parsing means looking for begin-tags and length fields and/or end-tags of pictures packages. The resulting bitmap data is copied into a byte array and will loaded into a movieclip using the flash.display.Loader class ( bytePictureLoader. loadBytes( byteArray ); ).[code]While testing, I found out that in some cases the data stream becomes currupted, i.e. data is lost and/or the transmittion is incomplete.
A good thing is that this error is reproducable.It seems that as soon as the Flash Application Window is dragged (moved on Windows Desktop) the stream lacks data. The same error occurs, if too much data is sent to the client. The results are performance problems, data loss and other strange effects. The more data is sent on the stream, the more data has to be parsed and the more data gets lost somehow. Sometimes this leads to a memory problem, because Begin- and End-Tags aren't transmitted correctly. In order to fix (counteract) that, I discard data as long as there is no Begin-tag found and the buffer is cleared when the size exceeds 1Mb.It works so far, but the application lacks performance and stability.I.e. If 20 bitmaps per second with 620x390px are sent to the client, the client only receives 16 to 17 bitmaps, if the application does nothing else.If 30 bitmaps per second with 620x390px are sent to the client, the client only receives about 20 to 21 bitmaps.I am guessing that using actuall video streams would be better, then sending one bitmap at a time in a byte stream.Is there a proper example on how to build a client app in flash to receive/parse a binary data stream?Does anyone else has recognized the lost-data problem or the interruption of streams?

View 3 RepliesI'm having a problem that I'm not sure is necessarily tied to the Flash, but I don't know what the root of the problem is yet.I have a SWF that connects to a socket using the Socket class. This works fine.I'm also making (jQuery) $.getJSON() requests to load certain page data. This works fine.
However, when the Flash socket is connected the Ajax requests stop being sent. By this I mean that it seems that the HTTP requests being made are stored in a queue while the socket is connected. As soon as I disconnect from the socket the HTTP requests continues to load fine. The HTTP request never times out (as it's not even being sent to the server), but just hangs there waiting...until I close the socket connection.
I've verified both in the jQuery and Adobe docs that both the Ajax (JSONP) requests and the connections using the Socket class are asynchronous, so I'm really confused as to why the socket connection would block the HTTP requests.
I have designed with Adobe Flash Professional CS5 a .fla project that integrates a client - server connection. After publishing it, I have the following issue:- when running the generated .exe file for Windows, then the connection to the server works perfectly- but when I am running the published .html file, then nothing is sent to the server.
I have tried to change the Publish Settings. When setting the Local Playback Security in Flash menu to "Access network only" instead of "Access local files only" then the last packet that was send using the .exe file is resent once and that's all (the html client does not receive the response from the server and the next connection attemps generate data transfer). I guess I have to change some security settings somewhere but I didn't find which.
Optivote IR8 is basically a voting system with a bunch of remote controllers, which can send IR signals to a receiver, which is connected to a computer through a USB port. And I'm trying to write my own little software for that with Flash.Optivote receiver communicates with software through a virtual serial port. When I connect to that port through PuTTY, I can see signals whenever I press any button on the remote controllers. Although, when I connect to that port through Serproxy (which relays a socket connection to a serial port connection), the remote controllers don't seem to work. I just get the same signal every half a second or so, over and over. I'm guessing the receiver is trying to make some kind of handshake this way.
The thing I can't figure out is what PuTTY does that Serproxy doesn't to make the serial port connection work. Maybe there's some proper way to tell the other end when I connect?(I use Serproxy, because Flash applications cannot connect to a serial port directly, but supports socket connections)

In a project that I'm working on, I have to be able to read input data from a serial port. The input data will be very simplistic in nature. I'm guessing more like a on/off, yes/no, true/false style of operation.I have found some examples in other languages, but nothing in AS3 or AS2. Could anyone send any sample code or a link to a tutorial that gives me some lead way on this? Which approach is better, going with a Flash projector piece, or building it in AIR? The final piece will be on a PC based system.
