Connecting the world…



A few days ago I installed and configured the SSL VPN solution OpenVPN ALS, which is a direct descendant of Adito, which has a fork of SSL-Explorer. OpenVPN ALS is a simple to use SSL VPN solution to publish multiple services via browser-based portal. OpenVPN uses Java to publish multiple services. OpenVPN ALS isn’t an enterprise SSL VPN solution, but nevertheless useful for SMB environments with no special needs.

I made some nodes for the installation of OpenVPN ALS, which helps you installing the SSL VPN solution. The notes can be found below. I used the following hardware to install OpenVPN ALS.

  • Simple Dell Latitude D830 laptop with VMware Workstation;
  • Ubuntu Server 10.10;
  • Adito 0.9.1;

Follow these steps to install OpenVPN ALS.

– Install Ubuntu Server 10.10

– Update / upgrade Ubuntu packages

sudo apt-get update

sudo apt-get upgrade

– Install tasksel, the Debian/Ubuntu tool that installs multiple related packages as a co-ordinated “task” onto the system

sudo apt-get intall tasksel

– Install the LAMP server and OpenSSH server using tasksel

sudo tasksel

– Install Java JDK and the dependencies including Java JRE

sudo apt-get install default-jdk

– Install ant, the Java-based build application comparable to make

sudo apt-get install ant

– Download the adito.tar.gz and copy it to the directory /opt

– Extract the tar.gz file

sudo tar zxvf adito-0.9.1.tar.gz

– Start the installation

cd adito-0.9.1

sudo ant install

Buildfile: /opt/adito-0.9.1/build.xml



[echo] Couldn’t find tools.jar from $ADITO_HOME/adito/lib

[echo] Copying the tools.jar from your JDK

[copy] Copying 1 file to /opt/adito-0.9.1/lib



[java] Starting installation wizard…..

[java] Point your browser to http://aparedis.geelen-beton.local:28080.


[java] Press CTRL+C or use the ‘Shutdown’ option from the web interface to leave the installation wizard.

– Open the web browser for further configuration

http://<ip address>:28080

– Configure the multiple options, like SSL certificate, user authentication, super user and web server parameters. I used Active Directory integration as user authentication method, which works like a charm.

– Install the Adito service

sudo ant install-service

– Start the Adito service

sudo ant start

– Configure the SSL VPN applications, by opening a web browser and login with the configured super user

https://<ip address>

– You can find multiple extensions on the internet to publish applications like RDP and a Mozilla Firefox web browser. An example of a website to download extensions can be found here.

Have fun!!!
