Elad,
Socket based connections to low ports require a special policy file be placed on port 80 of the target server. Flash Player delegates server security to the server by loading an XML file on this default url : http://server/crossdomain.xml In the case of flash.net.Socket and flash.net.XMLSocket, you need to allow low port connections within this file like so: <?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd";> <cross-domain-policy> <allow-access-from domain="*" to-ports="507" /> <allow-access-from domain="*.mysite.com" to-ports="507,516" /> <allow-access-from domain="*.myothersite.com" to-ports="516-523" /> <allow-access-from domain="www.myothersite.com" to-ports="507,516-523" /> <allow-access-from domain="www.mysite.com" to-ports="*" /> </cross-domain-policy> Assuming you want to connect to port 21 (FTP) you would do the following: <?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd";> <cross-domain-policy> <allow-access-from domain="*" to-ports="21" /> </cross-domain-policy> Also make sure to limit the domain to the domain that your SWF file is hosted from. * allows connections from flash players from any domain. Here is my post on the subject from 2003. http://chattyfig.figleaf.com/pipermail/flashcoders/2003-September/089698 .html Also many times there is no HTTP server on specialized hardware. I wrote this HTTP server in python to serve the crossdomain.xml file without the need to install a heavier process like Apache or IIS. Make sure to modify the crossdomain.xml data embedded in the server below if you go this route. http://www.powersdk.com/download/FCHS.py Hope this helps.

The remote server I am trying to connect is on port. Is it possible to create a connection to the remote server? I am keep getting securities error messages. Best, Elad.
