Securing PHP when using Virtualmin

    Recently for a fun project, I decided to set up an automated shared web host to test my coding abilities. I decided to go with a simple name, similar to one of my other domains. I ended up with Chris Host It. Sure its cheesy and not very professional, but this is just a test project after all. The problem was the back end I went with didn’t secure PHP as well as I wanted it to by default, so I had to fix that up. So here is a quick guide on securing PHP when using Virtualmin.

    So to stay with the game, I decided to deploy IPv6 on my servers. The only issue with it though is that my ISP seems to only offer it through a tunnel, or a IPv6 6rd tunnel to be exact. So after spending awhile with trial and error, here is how I access charters IPv6 network.
