The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.
We don’t think that the Raspberry Pi is a fix to all of the world’s computing issues; we do believe that we can be a catalyst. We want to see cheap, accessible, programmable computers everywhere; we actively encourage other companies to clone what we’re doing. We want to break the paradigm where without spending hundreds of pounds on a PC, families can’t use the internet. We want owning a truly personal computer to be normal for children. We think that 2012 is going to be a very exciting year. [About Raspberry PI]
I did create this mind map a while ago, and found it while going through my dropbox folders. Linux server Monitoring “You can't correct something you can't measure” is in version v 1.0.0
You’ll find in this mind map
What to monitor, how and the most useful commands to detect what happening on your Linux server.
Why a mind map?
A mind map is a diagram used to visually outline information. mind map help you take notes, brainstorm complex problems, and think creatively.
This script is working on all Linux standard distribution, but use at your own risk! The script has been made to automated the creation of iptables rules. There is an easy to use menu as well

and add depending on your Ubuntu version either
For Ubuntu 10.04 Lucid:
deb http://nginx.org/packages/ubuntu/ lucid nginx
deb-src http://nginx.org/packages/ubuntu/ lucid nginx
For Ubuntu 12.04 Precise:
deb http://nginx.org/packages/ubuntu/ precise nginx deb-src http://nginx.org/packages/ubuntu/ precise nginx
Now you can run
When using the public nginx repository for Ubuntu, you’ll get this error
W: GPG error: http://nginx.org lucid Release: The following signatures
couldn't be verified because the public key is not available: NO_PUBKEY ABF5BD827BD9BF62
First of all this is only warning and you can ignore it, if you know what are you doing and in case you prefer to add public key, used for signing packages and repository, just run:
gpg -a --export 7BD9BF62 | sudo apt-key add -
wget http://nginx.org/packages/keys/nginx_signing.key cat nginx_signing.key | sudo apt-key add -
apt-get update should now run fine, however after running an
apt-get install nginx
you may still get this kind of error:
dpkg: error processing /var/cache/apt/archives/nginx_1.2.2-1~precise_amd64.deb (--unpack): trying to overwrite '/etc/logrotate.d/nginx', which is also in package nginx-common 1.1.19-1 dpkg-deb: error: subprocess paste was killed by signal (Broken pipe) Errors were encountered while processing: /var/cache/apt/archives/nginx_1.2.2-1~precise_amd64.deb
just remove nginx-common and retry
apt-get remove nginx-common
