.swf receiving sockets communication from localhost

Is there a way to avoid " Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: " for socket usage on a local machine in the .swf target ? I read some but it turns out I can’t remember what worked last time I had this problem.

Am using the haxe-ws lib. Sending from a cpp target to the said localhost flash running in a debug flashplayer. Should I get a server running instead and run it in a browser, am running out of ideas but do remember was possible to do some other way.

Edit for the detailed error under “debug” compile:

Does it work if you use a different sandbox type?

I believe Haxe supports -D network-sandbox, I forget if there is another option as well

I use -Dnetwork-sandbox, downloaded a command tool from adobe that allows to set the .swf to network-sandbox and it says it has thr network rights. Nothing.
The thing is if I use echotool.exe it does send the first message and gets a reply from the echotool but from then on it gives me a sandbox violation. I have altered mms.cfg to include and have Security.LOCAL_WITH_NETWORK and Security.allowDomain("*");
I also am serving a crossdomain.xml on the correct port but it never gets asked.
Kind of stunned I can’t get around this, remember I did this some years ago for some other application. I’m stuck on .swf because of the video support right now and mapping the keyboard to start/stop stuff is kind of too kamikaze.

As of openfl 4.1.0 with lime 3.1.0, it just works.
Looked at the change log and found nothing about it. Can’t complain. :slight_smile:

I also have a problem with this and didn’t find solution yet.
my config: openFl= 4.7.3, lime=3.7.2

I create socket connection but when I try to connect with remote IP (from localhost) I get this error:
Error #2048: Security sandbox violation on Flash target.
On html5 target everything is OK.
I try a lot of solutions but still can’t connect remote socket from my machine.
Does anyone has solution for this?

Take a look at http://lib.haxe.org/p/extension-networking/ , Daniel came up with a very clean solution to serve a required file so that flash allows communication.

Well, it looks it isn’t solution for me because I use flash only for debug (because it’s fast)-my targets are html5 and mobile and those two not supported with this library.

Flash socket communication might require the correct “sandbox type” when compiling the SWF, or a “crossdomain.xml” file on the server. It might also be difficult to do when you run Flash standalone, it may work better with openfl test flash -web inside a web page.

You might also be able to get it to work with a combination of the above and making exceptions for your local file system in the settings manager
