[SOLVED] java socket permission error when outside of LAN

I am kinda a newer server admin, running my own in-home server/media center.

I am trying to use Cambozola to stream a webcam and put it in a webpage. I am using Motion for the webcam server. Motion is up and running fine.

I was searching through Motion's documentation and found this:
http://www.lavrsen.dk/foswiki/bin/view/ … bcamServer
which talks about a Java applet.

I know nothing of Java but I followed the directions here:
http://www.charliemouse.com/code/cambozola/
I installed "ant" and "openjdk-6-jdk" along with all of their dependancies.

I build this SUPER simple website using code from the links

<html><body><h1>It works!</h1>
<p>This is the default web page for this server.</p>
<p>The web server software is running but no content has been added, yet.</p>

<applet code=com.charliemouse.cambozola.Viewer
    archive=cambozola.jar width="640" height="480" style="border-width:1; border-color:gr$
    <param name=url value="http://192.168.0.101:8081">
</applet>


</body></html>

Motion works fine on port 8081 from anywhere. So i can go to http://external.ip.address:8081 and I have no problems.

The Cambozola applet works great when i am inside my home network where the server is located. When i am outside my own network (or simulating it using anonymouse.org) I get the following inside the box that would be the webcam.

Security.AccessControlException: access denied (java.net.SocketPermission 192.168.0.101:8081 connect

and the rest of the message was cut off by the box.

I am running behind a generic wireless router and i have all relevant ports forwarded to the server. I thought that it might be a port issue so i forwarded ports 1-10,000 to the server temporarrily to try and nail that down. At the same time i disabled my GUFW firewall.

Still no joy.

Anyhelp?

It's basically just a permission issue on the applet level. Have a look here for some more information (and how you can fix it).

If it is permission in the applet how come it works great inside my network?

AWESOME!

never using Java before i had no idea about permissions. This solved it!

 nano java.net.SocketPermission

in the java security folder. Then

grant {
  permission java.net.SocketPermission
        "localhost:port", 
	"connect, resolve";
};

Arch Linux
