Crypted disks with remote key placed on http server

This page contains few information how to create crypted disk using dm_crypt, lvm, gpg with remote key stored on http server.
The advantage is to have key, used for unlocking crypted disk(s), somewhere on the server instead have it on USB.

* You can easily delete this key if your disks are stolen and nobody can access them any longer...
* If you use USB stick to save key then you need to have it connected to the machine with the cyphered disks every reboot - usually it will be plugged all the time to the server which destroy all security.
* Keys are downloaded automatically every reboot from remote HTTP server (if not your disks will remain locked).

All commands were tested on Debian and should be also applicable on other distributions.

HD Trailers downloaded by wget

I found nice page http://www.hd-trailers.net/ accessing HD trailers from Yahoo or Apple through downloadable mov files. It's quite useful to have mov files instead of using flash player especially if you have slower Internet connection.

Here is short wget command which download mov files from Apple site into directories:

#!/bin/bash

#480, 720, 1080
RESOLUTION=480

wget --recursive --level=2  --accept *${RESOLUTION}p.mov \
--span-hosts --domains=movies.apple.com,www.hd-trailers.net \
--no-host-directories --cut-dirs=2 --exclude-directories=/blog \
http://www.hd-trailers.net/

Enjoy ;-)
