VPNBook : Free VPN

VPNBook is a 100% Free VPN service without any need for registration or sign-up.

Here is how I did my setup : open a terminal :
Applications > Terminal and copy and paste the following line :

sudo apt-get install network-manager-openvpn-gnome 
( will pull in packages network-manager-openvpn and openvpn, the other needed packages are already installed in a default installation ).


Wingpanel > Network-manager-applet > Edit Connections....

Network Connections > VPN > Add  , Choose a VPN Connection Type > PPTP > Create...


Go to VPNBook and look for the PPTP settings. I choose Server #3 : uk180.vpnbook.com (UK VPN - optimized for fast web surfing; no p2p downloading).



 

Connection name : VPNBook-PPTP-UK ( you can set any name )
VPN tab :
Gateway : uk180.vpnbook.com
User name : vpnbook
Password : qe6resTe ( password changes every one to two weeks ! ,
https://twitter.com/vpnbook )
Check : Show password
Check Available for all users.

 

Go to Advanced and check Use Point-to-Point encryption ( MPPE ) > press OK button.

Now can choose your VPN connection in the network-manager-applet...

To setup OpenVPN : Go to VPNBook and download one of the OpenVPN Certificate Bundles ( e.g Server #3 ).



Create a new folder in your Home directory and name it e.g. openvpn-config.


Move the downloaded  ( Applications > Files > Downloads ) OpenVPN Certificate Bundle ( VPNBook.com-OpenVPN-UK1.zip ) into the openvpn-config folder and right click and choose Open With Archive Manager.
Hit the button Extract files from the archive 




Choose one of the .ovpn files e.g. vpnbook-uk1-tcp80.ovpn.
We need to create three files in the openvpn-config folder with the names : ca.crt, client.crt and client.key :



For the next copy/paste actions to work with Scratch ( default text editor ) we need to change it's Autosave feature :


Applications > Scratch > Menu ( gear icon ) > Preferences : uncheck Save files when changed .
This is a known bug : pasted text in Scratch will get lost with Autosave feature enabled...

Open the file vpnbook-uk1-tcp80.ovpn and copy the lines between the <ca> tags and paste into the file ca.crt, save ( second button from the left ) and close.
Copy and paste the lines between the <cert> tags into the file client.crt, save and close.
Copy and the paste the lines between the <key> tags into the file client.key, save and close.


Wingpanel > Network-manager-applet > Edit Connections...
In the window Network Connections > VPN > Import  and navigate to the file vpnbook-uk1-tcp80.ovpn.

Window opens ( Editing vpnbook-uk1-tcp80 ) :
Connection name : choose whatever you like ( I choose VPNBook-OpenVPN-UK ).
Uncheck Connect automatically
VPN tab :
Authentication > Type : choose Password with Certificates ( TLS )
User name : vpnbook
Password :  qe6resTe ( password changes every one to two weeks ! )
User Certificate : navigate to client.crt
CA Certificate : choose ca.crt
Private Key : choose client.key
Finally : Save

Now can choose your VPN connection in the network-manager-applet...

Viewnior, A Simple Pictureviewer



Viewnior is an image viewer program. Created to be simple, fast and elegant.

The download page shows that there is no package for Ubuntu....and so we need to compile to make a deb-package.

Download the source from here : http://cloud.github.com/downloads/xsisqox/Viewnior/viewnior-1.3.tar.gz

Go to Downloads in a terminal :
cd Downloads

First install the necessary tools :
sudo apt-get install build-essential intltool dh-make

Development libraries :

sudo apt-get install libgdk-pixbuf2.0-dev libgtk2.0-dev

Extract
tar xf viewnior-1.3.tar.gz 

mv viewnior-1.3.tar.gz viewnior-1.3/
cd viewnior-1.3

dh_make --createorig

It will ask :

Type of package: single binary, indep binary, multiple binary, library, kernel module, kernel patch?
 [s/i/m/l/k/n] 


Just type s. Then it will show you some package information that you can edit. Just hit Enter.
Next message :
Done. Please edit the files in the debian/ subdirectory now. viewnior
uses a configure script, so you probably don't have to edit the Makefiles.


dpkg-buildpackage 

At the end ( won't take much time ) :
dpkg-deb: building package `viewnior' in `../viewnior_1.3-1_amd64.deb'.
dpkg-genchanges  >../viewnior_1.3-1_amd64.changes
dpkg-genchanges: including full source code in upload
dpkg-source --after-build viewnior-1.3
dpkg-buildpackage: full upload (original source is included)


cd ..
ls
viewnior_1.3-1_amd64.changes  viewnior_1.3-1.debian.tar.gz  viewnior_1.3.orig.tar.gz
viewnior-1.3  viewnior_1.3-1_amd64.deb        viewnior_1.3-1.dsc


There it is : viewnior_1.3-1_amd64.deb......

Installation is done with gdebi, a simple tool to install deb files ( sudo apt-get install gdebi ).

Elementary OS Luna Review




......I have to tell you after test-driving it for the last four days I have come to the conclusion that I have really been doing myself a disservice and so are you if you don't download this distro and give it a try..... 


......this is a lightning-fast, responsive desktop that is just ready to go out of the box....

Mozilla’s UX-Nightly Build Of Firefox

The UX Nightly branch is the branch where developers can test out new features and experience them for a while before knowing if it’s something they want to ship.

Go to this page : http://people.mozilla.org/~jwein/ux-nightly/ ( or this one ) and download the appropriate build ( 32 or 64-bit, you can find out which one you need by going to Applications > System Settings > About ).
In my case it says : Version: 0.2 "Luna" ( 64-bit ).


Navigate to Downloads and open firefox-27.0a1.en-US.linux-x86_64.tar.bz2 with
Archive Manager ( just click on it ).
You will have a folder named firefox.
Assuming that you have installed and used firefox from the repositories before, I will rename the folder firefox  firefox-ux and move the folder to my home directory :
mv firefox/ ../firefox-ux
cd ../firefox-ux
./firefox -P

In the window that will open create a profile : call it ux  and start UX with this profile:



If all goes well....


Create a desktop file in ~/.local/share/applications with the following lines :
[Desktop Entry]
Version=1.0
Name=Firefox Ux
Exec=/home/username/firefox-ux/firefox -P "ux" --no-remote %u
Terminal=false
X-MultipleArgs=false
Type=Application
Icon=/home/username/firefox-ux/browser/chrome/icons/default/default48.png
Categories=GNOME;GTK;Network;WebBrowser;
MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/rss+xml;application/rdf+xml;image/gif;image/jpeg;image/png;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;x-scheme-handler/chrome;video/webm;application/x-xpinstall;
StartupNotify=true


Replace username with your username.....

The -no-remote switch will make it possible to run firefox with different profiles simultaneously ( see : http://kb.mozillazine.org/Command_line_arguments ).

Log out and in to see Firefox UX occur in Slingshot.

Mount Data Partition At Boot Time

I've created a large Data partition using Gparted. ( filesystem : ext4, label Data ).


Create mountpoint :
sudo mkdir /media/Data

Change ownership to user :
sudo chown $USER:$USER /media/Data

Data partition will be shown in left pane in Files, and manually mounted by clicking on Data.


In Terminal the command mount will show ( among other lines ) :
/dev/sda3 on /media/Data type ext4 (rw,nosuid,nodev,uhelper=udisks)

Adding this line to the file /etc/fstab will mount the partition at boottime :
sudo nano /etc/fstab

Add the line :
/dev/sda3 /media/Data ext4 rw,nosuid,nodev,uhelper=udisks 0 0

Get it mounted without reboot :
sudo mount -a

OpenDNS And Google Public DNS

OpenDNS and Google Public DNS are free, global Domain Name System (DNS) resolution services, that you can use as an alternative to your current DNS provider.





Edit Connections....


In my case : Wired > Edit > IP4 Settings

At Method open the dropdown menu and select Automatic (DHCP) addresses only.

In the DNS servers field, enter the following IP addresses, separated by a comma.

For OpenDNS : 208.67.222.222, 208.67.220.220

For Google Public DNS : 8.8.8.8, 8.8.4.4

Restart Networkmanager ( might not be needed ) :

sudo service network-manager restart

Restart your browser...

To check run the next command in a Terminal :

nm-tool | tail -n 8

Pantheon Session With Compiz

You can create a different session running Pantheon desktop with compiz as window-manager.

First we need to install compiz :

sudo apt-get install compiz compizconfig-settings-manager compiz-plugins-extra

Navigate to /usr/share/xsessions and create a file pantheon-compiz.desktop  :

sudo nano pantheon-compiz.desktop

Paste into the file the following lines :

[Desktop Entry]
Name=Pantheon compiz
Comment=This session provides elementary-compiz experience
Exec=gnome-session --session=pantheon-compiz
TryExec=wingpanel
Icon=
Type=Application


Use Ctrl+O to File Name to Write, just hit Enter and then Ctrl+X to Exit.


Then navigate to /usr/share/gnome-session/sessions and create a file pantheon-compiz.session :

sudo nano pantheon-compiz.session

[GNOME Session]
Name=Pantheon Compiz
RequiredComponents=gnome-settings-daemon;
RequiredProviders=windowmanager;
DefaultProvider-windowmanager=compiz
FallbackSession=ubuntu
DesktopName=Pantheon


Again use Ctrl+O to File Name to Write, just hit Enter and then Ctrl+X to Exit.

Log out...

If your button-layout got messed up, start dconf-editor ( package dconf-tools ) and check the settings at :
org > gnome > desktop >wm > preferences > button-layout.





To be able to make a screenshot of  the login screen :

sudo apt-get install xserver-xephyr

UPDATE : WARNING : next tool could destroy all your dconf settings !  Do not use....

Run the next command during a normal session :

lightdm --test-mode

enlarge the window and make a screenshot.....to quit type Ctrl+C in the terminal.

Update :
I found out that Plank did not work nicely with compiz. Minimizing windows will not always move the windows out of sight in the direction of the panel ( as wanted  ), but  also to the upper left corner.
I replaced Plank with Docky :
sudo apt-get install docky


System Settings > Tweaks > Cerbere > select Plank and remove (-), then add (+) Docky.
Re-login....


Window decoration theme : https://launchpad.net/~shimmerproject/+archive/ppa/+index?field.series_filter=lucid ( greybird-git )

Fix Boot Screen ( Plymouth ) After Installing Nvidia Drivers





This boot screen gets lost after installing the driver for my Nvidia card ( Geforce GT 330 ).
The following commands in a terminal ( during a normal session ) will show your current theme :

sudo plymouthd ; sudo plymouth --show-splash

It will show two screens....to quit type :

sudo plymouth quit

If the above does not work you will need package plymouth-x11 :
sudo apt-get install plymouth-x11 


To get it back during boottime I've tried different solutions , but the one that worked for me was the following :

sudo nano /etc/default/grub

Look for the line :
#GRUB_GFXMODE=640x480

Just underneath write the line :
GRUB_GFXPAYLOAD_LINUX=auto


^O ( WriteOut ), File Name to Write ( hit Enter ) and ^X ( Exit ).

Then :

sudo update-grub

Panel And Slingshot Transparency


Open Files as Administrator.


Enter your password....

Navigate to the folder /usr/share/themes/elementary/gtk-3.0/

Find the file apps.css and open it ( scratch-text-editor ).

Scroll down to the following section :


Just below is the line : background-color: alpha (#000, 0.7);

#000 is the color ( see : http://www.color-hex.com/ ), 0.7 is the transparency.

Change the number 0.7 into a lower number ( e.g. 0.3 ).

To see the change type in a terminal :

killall wingpanel


In order to make the slingshot-launcher and the drop down menus from the panel transparent, we need to change another file :

cd /usr/share/themes/elementary/gtk-3.0/
sudo nano granite-widgets.css

Type Ctrl+W ( Where Is ) and type popover_bg and hit Enter.


There are three lines containing alpha and we need to change the last numbers ( 0.97 ) in them ( make them lower ). So it will look like this :


Type Ctrl+O ( WriteOut ), hit Enter and Ctrl+X

To see the changes :
killall wingpanel
killall slingshot-launcher

A Star Is Born : Luna....





The next generation of elementary OS is here : Luna. Lightweight and beautiful. All-new apps. A refined look. 

Based on Ubuntu 12.04 LTS ( (Precise Pangolin).




Elementary OS

Technical Specifications

After you have installed a copy of Elementary OS, it's wise to check the recommendations on this page : Top Things To Do After Installing Luna.

Following the above link, the things I did were :

Check for updates and installing them. In a Terminal :

sudo apt-get update && sudo apt-get upgrade 

Adding a community ppa : Elementary Update :

sudo apt-add-repository ppa:versable/elementary-update
sudo apt-get update

Then install Elementary Tweaks, a improved System Settings ( Switchboard ) :

sudo apt-get install elementary-tweaks

For package management I use synaptic and gdebi :

sudo apt-get install synaptic gdebi

To upgrade the kernel :

Applications > Synaptic Package Manager  and I looked for the highest number
linux-image-3.8 ( Synaptic > Quick Filter ).
