Imo, people who doesn't know basic, or at least, cannot even do basic search, should not open a server. But right, next guide will have a section "to go further" explaining security and other

I could not agree more. But your guide makes it possible to host server without almost any knowledge at all. At that point, "should" and "should not" -things don't really matter.

If you need help with next guide, i'm up. I was actually thinking to make a Debian guide myself, with exception of using two servers, one for emulator and one for web-server. But i never seem to have time to do it.
