.htaccess
This is just a really quick note for me to refer to when I forget how to do this off the top of my head. For more details about htaccess, here is an excellent link:
.htaccess tricks
These entries go in httpd.conf
AccessFileName .htaccess
<Directory /path/to/protected/dir>
Order Deny,Allow
</Directory>
These entries go in .htaccess in the directory you wish to protect.
AuthType Basic
AuthUserFile /path/to/.htpasswd
AuthName "Name of Session"
<Limit GET PUT POST>
require user admin
</Limit>

What in the hell is a KrnlPanic? Well, a KrnlPanic is me! Actually, let's start with "What is a kernel?". The
kernel is the core of your operating system (OS), whether your OS is Linux, Unix or windows. The kernel takes
care of all process management (what program runs and when), memory management (which parts of memory get used for what) and
also, the kernel takes care of interfacing the OS with your computer's hardware (disk drives, sound card, modem, network card, etc).
Now...since the kernel is doing all of these extremely important jobs, it stands to reason
that if it has an error, it will be a Bad Thing(tm).
If you use windows, you know a kernel panic as a "BSOD" or Blue Screen of Death. Or how about "Invalid Page
Fault in KERNEL32.DLL". I'm sure you've probably seen both of those. In Linux, a Kernel Panic is normally plainly stated
so. At boot time is when you will see most linux panics. I have yet to see a linux kernel panic while the system is running.
You may have seen "Kernel Panic: init not found" or "Kernel Panic: VFS unable to mount root fs on 2:00". All of these previously
listed errors are because of something that happened to the kernel that it couldn't handle, whether it was an access to an
invalid memory location or the inability to find the initialization files it requires.
I hope that sufficiently explains things. Oh yeah...KrnlPanic is also my name ;-)
- Rick
