Actionscript 3 :: Security Error 2048 On Socket Connection
Feb 11, 2012
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 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 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 have created a crosdomain policy file, I have added code to my flex app, and I still get security sandbox violation...have I done something wrong? Here are my errors and file snippets:
Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: http://mysite.com/folder1/folder2/media/swf_demo.swf cannot load data from http://mysite.com/folder1/folder2/media/locXML.xml.
swf_demo.swf is my flex application
The following lines have been added to my flex application:
Security.allowDomain("mysite.com");
Security.allowDomain("www.mysite.com");
Security.allowDomain("http://mysite.com/folder1/folder2/media/locXML.xml");[code]..

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 am trying to connect to a socket server with the following:
Code:
Security.loadPolicyFile("xmlsocket://192.168.1.111:843");
var xmlsocket:XMLSocket = new XMLSocket();
xmlsocket.connect("192.168.1.111", 4000);
stop();
Here is the policy file:
Code:
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all" />
<allow-access-from domain="*" to-ports="*"" />
</cross-domain-policy>

I seem to be getting this error everytime I try to connect to my XMLSocket server, does anyone have any idea what this is. I do have a crossdomain.xml file at the server root. The crossdomain file consists of:

I have been developing an application(a website to be more precise) which consists of a flex front end which is constantly sending and receiving data from the back end which is programmed in java. The connection between the two components is being done through blazeds. This worked fine while I was running it locally, however when I uploaded both sides of the application to a tomcat server(online) the following error is being returned when a connection between the components should occur:URL...I have read around about this error and many seem to getting this error when making connections between different servers, unlike here, where the connection is occurring within the same server.

I'm attempting to create an XMLSocket that connects to a PHP-written socket server.I think my code is pretty sound. I used to receive an IOError, but now that is solved and I keep receiving "Error #2048: Security sandbox violation". My .swf, socket server, and crossdomain files are all in the same directory.
My ActionScript:
Code:
package
{
import flash.display.MovieClip;
import flash.events.IOErrorEvent;

i've created a socket extension class. the pseudo code below tries to make a socket connection using the passed parameters. if there is an security error, such as the port number not being an acceptable port number, i want to handle the security error.
however, i can't catch the security error. a popup window appears with a description of the error and my errorHandler function is never called.

My SWF resides on domain A, is loaded by a web site on domain B and is trying to ping URL (URLLoader.load) on domain C. But I am getting "#2048: Security sandbox violation" .. why? Of course I have read the manual, I saw the security white paper but I do not understand it. Don't you know any blog or such where it is explained for dummies? With lots of examples and maybe a table showing what is allowed and what is not?

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.

am having a little trouble with a simple form on one of my flash websites. The form takes three pieces of information (name, email and description) and should submit this data to a php page in the same directory where it emails it to me.
When I run the swf from the Flash CS3 Pro program, the connection and submission goes smoothly and I receive the email.But when I load the swf and the php file onto my site and try it over the internet, it gives me the following error:

I'm running into an issue with an HTTPS post request where I get the following error (please note some of the URLs have been modified to protect privacy):
Code:
Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: http://[local_ip_addr]/[my_swf].swf cannot load data from https://dev.[domain_name].net/[path_to_xml].
When I review the crossdomain.xml I have the following (again, sections omitted to protect privacy):
Code:
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"></site-control>
[code]....
So that appears to be set up correctly. Requests sent to the HTTP protocol happen just fine, it seems only to be the HTTPS. Do I need to set up Security.allowInsecureDomain() to have this work or is there something on the crossdomain.xml side that I need to set further (such as <allow-access-from domain="*" secure="false" />)?

I'm writing a online application in flash and I'm trying to test the socket connection over a java server running on localhost. It works fine running in the CS3 environment using ctrl+enter and it's communicating with the server and sending information back and forth. But I can only test one client at a time like this. When I try to run the swf straight it isn't connecting. how to set up the permissions correctly so I can test locally?

I have 2 applications which I wrote in ActionScript 3.0 as client and C#.net as server. These are basic chat applications. Also I have a test website which is running under the same machine with chat server application.
Server application is listening 289 port, flash application connecting to server with domain and 289 port, it can talk with server during working on Flash. But when I put the flash in a html page, the socket connection is breaking after a while because of security reasons.
I know that is necessary to put a crossdomain.xml file on target website's root folder. The problem is here: Yes, there is a crossdomain.xml file like this:[URL]...

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?
