Seems that Symantec is now picking up socket_bridge.swf and reporting it as Downloader.Swif.C Trojan. I’ve submitted a false positive report, so hopefully it’s fixed soon, but in the mean time just a heads up.

Hmm, that’s a weird one I’ve not seen before. I’m really not that hot with Flash debugging I’m afraid!

I know Ionel who commented above has his own version of the socketBridge app with some revamped code. Basically the same functionality but with a nicer JS interface, might be worth a try if you can’t track down the bug.

Thanks! Moving it off the screen with an absolute position did the trick.

You know, I’ve been testing this a lot today and sometimes I get the following error for no apparent reason:

Error: Error #1502: A script has executed for longer than the default timeout period of 15 seconds.
at Boot_3D39A$/__trace()
at MethodInfo-65()
at SocketBridge$/connect()
at Function/http://adobe.com/AS3/2006/builtin::apply()
at flash.external::ExternalInterface$/_callIn()
at ()

If you just reload the page, no code changes, it works fine the second time around. Firebug reports the following in these cases:

uncaught exception: Error calling method on NPObject! [plugin exception: Error in Actionscript. Use a try/catch block to find error.].

@Kaiser Soze

A few options maybe, could try adding CSS display:none; div after the SWF has loaded with SWFObject ? Otherwise you could put it in a div which is absolutely positioned with top and left values of -100000px.

Sure I have had this working but can’t find the exact code I used sorry.

This is a great tool. I only have one issue: how would you hide it on the page if you don’t care to display the console output? I tried several ways to do this (putting the embedded object inside a hidden div, setting the object size to 0×0 or 1×1, etc) but none worked. The swf crashes if I set the size too small, and it doesn’t get loaded if I wrap it around an invisible div.

Any feedback on this would be greatly appreciated!

The way you call the callbacks using setTimeout is bound for failure: no quote escape for the string you pass to setTimeout. While it can be easily fixed i don’t think it would be very performant. A solution would be just calling the callbacks as usual and do setTimeout if necessary in the javascript code.

I wrote a small python policy server for the people that just don't want to write it :)

from twisted.internet import reactor
from twisted.internet.protocol import Protocol, Factory
_policy = "<cross-domain-policy><allow-access-from domain='*' to-ports='*' secure='false' /></cross-domain-policy>\0"

class PolicyHandler(Protocol):
 def __init__(self):
  pass

 def dataReceived(self, data):
  self.transport.write(_policy)

def main():
 f = Factory()
 f.protocol = PolicyHandler
 reactor.listenTCP(843, f)
 print "Policy handler running on port 843."
 reactor.run()

if __name__ == '__main__':
 main()
