Well, I've downloaded & installed Apache, and I've found it's not easy to configure.
Can any of you give me a hint on how to do a very basic secure configuration until I learn?
I just want to give access to one root directory and its subdirectories, without any forms, scripts or whatever. Just plain old basic html to start with. And, of course, no access to any other part of the disk.
This is my personal PC, and I use it to surf, email, ftp,... so I can't block all the ports as gorguts suggested.
