Ubuntu Cloud (Juju+Folsom) vs. DevStack???
location: ubuntuforums.com - date: February 5, 2013
I have installed DevStack 3 times, and each time was a success. I really LOVE using it, especially how it expands into "screen" and rejoining the stack and rejoining the screen after reboots. I even did some manual qemu-kvm to build a Windows 8 instance right in X windows on Ubuntu on my devstack server.
But now I am going to build another server, and wonder if I should go to the official Ubuntu Cloud "Canonical" version (using Juju, whatever that is) or just should I keep doing it the way I'm comfortable - Ubuntu 12.04LTS + devstack via github.. thoughts??? Anyone have experience with the two and can share their thoughts on how they differ?
This is all for my own personal lab, so I'm OK using DevStack although I always do a prompt tweak to stack.sh, just in case I accidentally want to run it again, so I can stop myself before its too late..
Thanks in advance!
Ubuntu Cloud Infrastructure Juju Boostrap error

Hi, while following this document:
I get to step 2 where I need to configure a yaml file
I vim it and here's my config:
# Specify the orchestra server's IP address
# Specify storage. In this case we are using webdav installed by orchestra.
# Specify cobbler's usr/pass
# Branch from where we will install ensemble
# juju-branch: lp:juju
# Mangement classes
then I get this message when I run juju bootstrap
error: Environments configuration error: /home/node/.juju/environments.yaml: environments.orchestra.default-se

Ubuntu LAMP setup for local sites from user directory

I just finished a tutorial on how to setup Ubuntu Desktop for local web site development served from you home/local directory instead of /var/www.

HOWTO: Setup Local Repository Mirror
location: ubuntuforums.com - date: November 1, 2007
If your like me, you and your friends have several machines running Ubuntu, Kubuntu, or other *buntu variants. After going through upgrades of all these machines, it can eat a lot of your and Canonical's bandwidth to download all the packages for each machine. There are other solutions such as apt-proxy, apt-cacher, etc. But what works best for me is apt-mirror, which creates a mirror of any Ubuntu, Debian, or any other deb repository. So if you have 20+ GB of hard drive space, you can setup a local repository mirror to speed up the upgrading process and save Canonical some bandwidth.
Step 1: Install apt-mirror
sudo apt-get install apt-mirror
(Universe repository needed)
Step 2: Configure apt-mirror
Configuring apt-mirror is fairly simple. We just need to modify the /etc/apt/mirror.list file.
gksudo gedit /etc/apt/mirror.list
kdesu kate /etc/apt/mirror.list
Ubuntu server users:
sudo nano /

setup startup scripts in /etc/rc.local
I am very new to Ubuntu Linux. I have installed Ubuntu on a Virtual Machine on my laptop. I am trying to follow this project --
I am stuck on adding the firewall.sh and adding it to the startup scripts in /etc/rc.local. (before Setting Up System Services)
I'm afraid i don't even know where to start on this. Do i add the file to rc.local or add what is in firewall.sh into rc.local? Please note, i don't even know what editor to use.
I tried "update-rc.d firewall.sh defaults", but i get a file not found error.
Any help would be greatly appreciated.

How can I setup SSH private key authentication?
location: linuxquestions.com - date: April 28, 2010
I heard there's a more secure way to log onto Linux using SSH, I think it's called SSH private key authentication. How does it work? Is it really more secure than typing in passwords? And how do I set it up?
