Adito (Now called OpenVPN ALS)


Adito is an open-source, browser-based SSL VPN solution. It’s a remote access solution that provides users and businesses alike with a means of securely accessing network resources from outside the network perimeter using only a standard web browser.

This is the open-source clone of SSL-Explorer after it went biz-o-matic.

Windows installer
My contribution to this project is a Windows-installer, check it out here, if you are looking for the SVN-version of Adito download here

Step-by-step guides
There are now three guides written by me on the topic.
1. Scroll down on the installer page for installation-tips
2. Scroll down on this page for a simple demonstration of a port-forward
3. NEW! Practical RDP guide here
4. Read the guide on running the Java 7 version 51

What the buzz about?
Pictures says more than words so please take a look in the pictureseries with description below.

You are first presented with a login window:

After successfully logging in you are at the main window

Usally the SSL Tunnel are common used. This technique open a port locally and forward it throught the server and to your destination.
In this example we create a port forwarding on port 4040 locally requests to on port 80 (www-default-port)
Create SSL Tunnel

After the creation we start the Agent. This is the software you run in the remote location straight from the browser. Since it uses default-java you would find access almost everywhere.
My rule is; if you can connect to your bank you can use Adito ;)
Agent launching

When it has launched you got a new little man-like icon in your sys-tray
Agent in systray

By right-clicking on the agent you will find items you have configed on the server. In our case the tunnel “Test” is available
Agent options

When the tunnel is activated the agent notify you and we are ready to use it

Now for some magic :) Connect to google through your server
Surfing through SSL Tunnel

As you can see this is pretty easy to use and manage a great product!

  1. Hi Lars,

    Thank you for your installer. I have recently begun seeing a Java security warning mentioning that applications by unknown publishers will be blocked in a future release. I was only able to get adito running with an older version of the java runtime on the server (version 6 update 17). If I use the SVN version, will I be able to update the java version on the server and avoid users being blocked when they next update java on their client machines? Any advice would be appreciated and thanks for your hard work.

    Here is more detail on the warning: This application will be blocked in a future Java security update because the JAR file manifest does not contain the permissions attribute. Please contact the Publisher for more information.


    • With the latest Java 1.7.0_51, this went from a warning to actually blocking the applet from running. The only way I could get it working again was to lower the Security level in the Java Control Panel (jcontrol) to Medium, from its default of High.

  2. Long time ssl-explorer user, just switched over to Adito.
    I have a problem when I configure the Java Agent Properties, when I set the values for Timeout, Keep-Alive,Shutdown interval etc. they seem to be multiplyed by 1000? Eg I set a value of 10 seconds, when I click save it sets the value to 10000
    Any idea why this may be happening or how to fix, its quite annoying as the agent keep shutting down.


  3. Hi,
