ActionScript 3.0 :: Error #2048 Socket Security Sanbox Error While Policy Server Is Working
Jun 9, 2011
I have an application that connects to a binary socket server running on port 2234. I use the python policy file server, which I downloaded from [URL], which runs on port 843. If the client app is trying to connect to a socket I can see that the server is receivng the request for a policy file and that it sends it to the client. However, in the client, I get a security sandbox error. How is this possible? And is it possible to check whether the client really received the policy file? BTW, here is my policy file:
<?xml version="1.0"?><!DOCTYPE cross-domain-policy SYSTEM "/xml/dtds/cross-domain-policy.dtd"><cross-domain-policy><allow-access-from domain="*" to-ports="*" /></cross-domain-policy>

I have a simple IRC socket that is used to communicate with servers for a web-based IRC client. Unfortunately, attempting to connect to a network results in a security error. I read up on sandboxes and their appropriate permissions, and then used Security.sandboxType to get the sandbox of my socket, which came up as remote. After reviewing the documentation, I still don't fully understand how I can enable my socket to connect to a remote IRC server. I tried Security.allowDomain,

I am trying to connect to a public resource using actionscript. I already have a PHP site set up to do this, but wanted to move it to Flash. From what I have read, Flash absolutely requires the destination location to have a crossdomain.xml file referencing the remote SWF. This seems absolutely ridiculous.
If I am correct, this means that public resources such as RSS feeds cannot be accessed using Flash? Is there any possible way to access a public file (like RSS) remotely from a SWF without having access to the destination server's crossdomain.xml file? I've tried using Socket and URLRequest, both giving the same "sandbox violation" error.

i got a problem with 'Security error',it happens when i try to connect my XMLSocket (Flex) with my Socket (Java)i have a domain:
alucardeck.mine.nu
i startup my apache tomcat 6.0 and in ROOT folder i have:
policyFile.xml and crossdomain.xml
(i had a doubt about what is the correct filename so i created both)both files contains:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>
well, yes, you can access using the default port 80, as it should be.(but probably my server will be down when u try to access it)so here is what i do: i run my Java server application.there i open 1 socket in port 19809.(i already tried with port 843 too) then, i run my Flex application: [URL]also i tried to run it in ROOT folder..the XMLSocket class is instanced like this:
xmlsock = new XMLSocket();
// add all listeners
Security.loadPolicyFile("http://alucardeck.mine.nu/crossdomain.xml");
// also tried "xmlsocket://alucardeck.m....
[code]....
i also notice when i start my Java Server application with 2 sockets listening ports: 843 and 19809, i notice Flex first try to connect to 843 and then 19809, and in both sockets i reply with that String from before.

I am using the XML/MX/Syndication libraires and getting a Security Error #2048 error. The error seems unreasonable to me in that there is no forward solution to it on the Internet. I have tried hardcoding security methods in AS 3 and also using a crossdmain.xml file in my root directory to no success. I am about to give up and use pure PHP. There should be a more simple solution to this.

I'm having trouble with an AS3 AMF RemoteObject request that is hosted on App Engine. I have a crossdomain.xml file in the root of the domain, and also one at the remoting endpoint.Here are the contents of the root crossdomain.xml:
<?xml version="1.0"?>
<cross-domain-policy>
<site-control permitted-cross-domain-policies ="all"/>[code].....
Loading the swf file and testing it on my machine works just fine... I think that may have something to do with me having the debugger version of Flash Player. When I push it up to App Engine to make it public, other clients access it and get a Client.Error.MessageSend Channel.Security.Error error Error #2048 url: http:[url].......I am using Flex 4 beta, and the App Engine Python runtime. I have tried full wildcard in the crossdomain, and even accessing the data endpoint at a relative URL so as to avoid this error.

How to I get my security policy working? My parent swf parses an XML doc and loads 2 children. It throws a 2148 security error, and only works in the Flash IDE. PARENT SWF 'I put it at the top of my code. That seemed like the proper event flow' flash.system.Security.loadPolicyFile("crossdomain.xml"); I've referenced my security file from my swf. I Also published my parent swf as 'network only' and put all the crossdomain.xml and everything else in the same folder. I need to click on the animations and have them place from a local computer at a kiosk. POLICY FILE 'Used"*" since there's not URL, it's all local'

I am attempting to setup a binary socket connection between flash running on my desktop and a Rabbit RCM3800 Microcontroller providing the server on my home network, which has no file system and has a very basic http server on it. Due to limitations of the microC I cannot run Java/Perl/Python or any other server on it other than setting up a server using its own native Dynamic C language (essentially manually opening and controlling sockets in C). I am able to successfully connect to a socket on port 3333 of the server and transfer information between the server and the .swf file when it is the sandbox type "local-trusted" (while I'm debugging in Flash).
Because of this I'm fairly certain the code to setup the socket between the server and flash works fine. My problem occurs when I try to run the .swf file as "local-with-network" (such as running it after publishing on my desktop) or "remote" (accessing the .swf file when it is located on the server) and it then requires a socket policy server to host a socket policy file on the server. On my server I have code setup such that whenever a socket opens on port 843 or port 3333 (my data port) and sends a stream of raw data containing the request <policy-file-request/>, the server writes back in ASCII the below code and closes the socket.
Code:
Select all<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "[URL]">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" to-ports="*" />
</cross-domain-policy>
[Code] .....
So for some reason flash times out while waiting for the socket policy file. I have tested sending the <policy-request-file/> over telnet, and have received the above policy file. I have also sniffed using wireshark and saw that my desktop sent the policy request and received the policy file. I am guessing that Flash times out because it is waiting for some kind of terminating character that states the end of the policy file, and to that end I have tried sending. Interestingly, instead of sending the policy file I have tried sending random data from the server to flash, and flash displayed the Warning: Ignoring policy file at (URL) due to incorrect syntax. Because I don't receive this warning when I send my policy file I don't think it is formatted incorrectly.
I have also tried using the below flash code to hold the socket request open indefinitely, but it also errors after 20seconds.
Code: Select allSecurity.loadPolicyFile("xmlsocket://192.168.1.59:843");
The .swf file will eventually reside on the server itself at 192.168.1.59/myProg.html. I have only tested the flash file remotely on the server a couple times, and in addition to the previous warnings/errors, I received the warning: SWF from (URL) may not connect to a socket in its own domain without a policy file.

I'm trying to get my Flash application to connect via socket to my server, so I need to set up a socket policy file server. It seems like there are various roll-your-own implementations floating around out there, but is there any kind of standard or best practice with what to use?
As an aside, it seems strange that Adobe imposes this restriction but doesn't make something readily available to support it.

I have a swf file "website.swf" on my desktop computer, in the www directory of my wamp server. The website loads the swf file fine.I have one textbox that i want to be able to load all the different contents of my site depending on the page, and in the same directory, I have all the different txt files (i.e. news.txt about.txt portfolio.txt etc)Now, when I'm running the swf file in Flash CS5, it makes me allow it and then works fine. However, once I publish and put it on the server, and then go to the website it returns "Error 2048". I've tried doing the crossdomain.xml suggestions to no avail.

I use UrlLoader.load() in my flash app. And I'm handling UncaughtErrorEvent.UNCAUGHT_ERROR to stop the app when an uncaught exception occured. UrlLoader.load() works when you are connecting the internet normally. But if the connection to the internet was lost after your browser loaded the app, SecurityError happens when UrlLoader.load() is called. I can not catch the SecurityError by using try catch and UNCAUGHT_ERROR happens and it stops my app. I don't want to stop the app when UrlLoader.load() failed because I'm just using UrlLoader.load() to log some unimportant information.
And I think timeout error also can be ocurred if it takes a long time to load. And I also don't want to stop my app due to the time out error. How can I solve those problems? And are there more other type of errors which can be ocurred and stop my app?

Before I start I should state I have read it all, I was following this, this and this (and more...) and still I cannot connect to our running server via Socket over the internet.
Here is what I try to in AS3:
[Code]...
We can see from the log output of the server that this is really sent to the connecting socket. A null byte is of course sent after the xml data. And after that, the server closes the connection. However, it seems that Flash somehow does not like it, as "Error #2048" still appears after ~3 seconds.

Im looking for a solution for the Error #2048 from Flash. I have a server program developed in Java using the class xSocket and it works fine. It manage the clients from Flash. Well, once i installed the server app in my domain "97.225.158.110" and running the client developed in Flash from my PC within Flash environment, it connects to the server with no problem. But, if i upload the flash to the domain and load it in a web explorer, it doesnt work. Well, i have been seeing many web pages mentioning the policy file and i will show you how i have done it: In the the Java App i have a event handler for incomming data where i idetify the incomming string:
Code:
if(data.equalsIgnoreCase("<policy-file-request/>")) {
Main.Log.append("Enviando archivo Politica Seguridad");
nbc.write("<cross-domain-policy><allow-access-from domain="*" to-ports="8090"/></cross-domain-policy>�");[code].............
Well, the java server app receive the string policy request and it should answer with the quoted file but the Flash never receive it and in a minute the Error 2048 appear.
