To get Netconnect to work.
First I installed the Java Plugin, which in my version of Ubuntu was fairly easy once I figured out that just installing Java was not enough. I also had to install the plugin for Firefox using the Synaptic Package Manager sun-java6-plugin.
Make sure you restart Firefox, and check that the plugin was installed by going to about:plugins
When you go through the VPN site, and Netconnect wants to start, I had to change the default password for root because that is the password it wanted --- could not sudo and do it, it wants only root password which in Ubuntu is set as a random hash by default.
Once I did that, it all worked and I successfully.
