I have released an update to this blog post: See
In what is becoming a bit of a , today I’ll be covering how to get Check Point SSL Network Extender installed under kubuntu. From the :
SSL Network Extender is a browser plug-in that provides clientless remote access, while delivering full network connectivity for any IP-based application.
It works based on java so the first thing you will need to install is sun’s java runtime client. You will need the repository installed and your system updated.
sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts
Once that is done you can restart Firefox and browse over to to make sure that you have java working.
You should see a message like this:
Verified Java Version Congratulations! You have the recommended Java installed (Version 6 Update 24).
Once java is working you can go to the snx website. If you don’t know the url ask your network administrator. You may be notified about popups so just allow them for your site.
Once you have accepted and reloaded the page you will be prompted to enter your username and password.
After this you will be asked to install an update to the software. This installs the software in the background. One thing to note is that it is looking for the root password and not the sudo password. Ubuntu ships without this set so you’ll need to set a root password using the following command.
You can confirm it’s set correctly using the command
and if you see the prompt change to “#” then you know it’s working. Switch back to the snx_install.sh window and enter the password.
Once you do that you should very briefly see a message saying that the install was successful. At this point the standard snx software is installed but you will probably see the error
Failed to initialize
When you run the snx client on the command line you will see:
