Note: Success..... anyone else wishing to install and build a firewall... the instructions are here...
http://www.linux.com/learn/tutorials/431659-build-powerful-linux-firewalls-with-firewall-builderand remember every step is a su or sudo ..... I found that when u had to add the
deb
http://www.fwbuilder.org/deb/stable/ maverick contrib
to the bottom of the source.list, you MUST have privileges, so what i did was navigate to the file, right click on the sources.list, go to scripts, open with gedit as root...... this will allow you to write to sources.list as a privilege user. Then at the bottom of the source.list you add
deb
http://www.fwbuilder.org/deb/stable/ maverick contrib
Save then close...
BUT BEFORE YOU GO FURTHER with those instructions on the linux.com site... In terminal, do
sudo apt-get update
first... so it then registers that in your own repository, then continue with the instructions... it then should, with luck for you, install... then after that... continue with the tutorial.... good luck...
Linux needs to invest in Simplicity if it is to stand a chance against Windows..
