Brand new to linux. Ive had it for a week, and im learning alot. I am mainly focusing on learning the terminal, by reading a free e-file book called "The Linux® Command Line by William E. Shotts, Jr." which is perfectly written for NOOBs such as myself. The way I understand it, is that a soft firewall is important no matter the OS. So with this being the case, I would like to set up a firewall. Unfortunately it seems a bit difficult to find documentation on how to do this. There is plenty of documentation, but not if you dont understand it(because you are new)
