Common .htaccess issues.

There is alot that can be done with an .htaccess file on an Apache HTTP Server server. Below are just some quick examples without much explanation outside of the comments I've left.

Side note: you can block out complete IP address blocks by leaving off the last digit of the IP address sequence. so if you wanted 12.34.56.1 all the way to 12.34.56.254 then you'd put 12.34.56

Download anything with Firefox and Firebug.

Advanced Downloading

Using Firefox and Firebug you can download just about anything, including finding the location of radio streams and such for online stations that attempt to restrict you to their ad filled players. A friendly reminder that this technique isn't foolproof, company's constantly change techniques to get their data and sometimes it is just impossible to obtain content. But for the most part anything is obtainable.

Block Facebook on Windows computer.

Theres a file located in C:\Windows\System32\drivers\etc called hosts that allows you to block domains. This isn't permanent, if the user you're trying to block knows this method then they can easily edit it themselves and regrant access themselves, just with past experiences most people don't know this method.

Apache permission issues with virtualhosts.

For many years I have played with Linux servers, and the one issue I always had that seemed non-fixable was permission issues between FTP and my virtualhosts on Apache. But now that has been solved.

ESXi 5 and the Intel 82579

This weekend I had the joy of setting up a new server, it's main purpose to replace 3 other machines that run like a stick in mud.

Specs:

Intel i7-2600k
ASUS P8Z68-V Pro GEN3 (Bundled with CPU)
Corsair Dominator DDR3-1600 32GB (4x8GB)
2 x Western Digital Velociraptor 300GB 10K hard drives
Seasonic X760 Gold Power Supply
Cooler Master CM690 II Advanced case
Intel Pro/1000GT Ethernet Card
APC BX1500G UPS

Problems right off the bat:

Intel 82579 onboard ethernet nic is too new for the standard ESXi 5.0 installation ISO. It will not install without an HCL listed ethernet card, there is however a work around to insert the drivers needed into the ESXi installer so that it will work. You will find the files listed below.
the i7-2600k does not support VT-D. The motherboard does support VT so you can run 64-bit images but you cannot use hardware passthrough as it isnot supposed at all. It's my understanding that the i7-2600 does support VT-D (note, no k after the 2600, there is a difference)

Aside from that, I personally do not need the hardware passthrough, but I obvisouly had issues with the ethernet connection. To solve that problem I found a blog post elsewhere that gave the drivers and the converter program.

Basically, all you need to do is download the ISO from VMware, download the ethernet driver and the customizer program then use the custom program to insert the drivers into the ISO, reburn that ISO to a new CD and then install from there.

Useful Code to remember

Since ESXi requires preallocated disks and won't work with Dynamic sized disks, they must be converted. This is easily done through an SSH connection to the server, CD'ing into the folder with the disk and running this command:
