As much as webmin must have taken a lot of effort to create and maintain, I truly despise it.
Not once has it correctly set up anything for me.
I've found that bearing down and simply learning how to properly edit configuration files for various things (such as apache) is the only way to know that your program will function the way you intend it to.
Apache's httpd.conf is not all that bad. Honestly, I'm a moron and I figured it out.
