Installing Ubuntu Touch has become quite easy these days and Android enthusiasts and developers across the globe have already started testing this brand new OS onto their devices. Ubuntu Touch brings a new platform to mobile devices and opens new opportunities to the developers. As we know, some of the BQ and Meizu devices officially run Ubuntu OS as part of their OEM and the OS is quite impressive.

Ubuntu developers have made the installation quite easy. It starts with just a couple of Linux commands and the installation process starts. It will verify your device and download and flash the software for you automatically. So you don�t need to worry about bricking your device by flashing the wrong file. However, you will need to connect your mobile device to a PC running Linux based OS and issue commands using ADB and Fastboot.

Follow the instructions below and get the server URL from the download section. Before you proceed, backup everything and read the instructions first. There are two methods. First will completely remove your previous ROM and perform a clean install. However, if you don�t want to lose your previous ROM, then go through the MultiROM method. This will help you install Ubuntu Touch OS alongside your primary OS.

Note: Needs a bootloader unlocked device.

How to install Ubuntu Touch using MultiRom

Installing Ubuntu on a phone

1. Shell and core applications
2. Connection to the GSM network on Galaxy Nexus and Nexus 4
3. Phone calls and SMS on Galaxy Nexus and Nexus 4
4. Networking via Wifi
5. Functional camera, front and back
6. Device accessible through the Android Developer Bridge tool (adb)
   
   
   
   Now it suppports only for  galaxy nexus and nexus 4 , anyway for the other phones too may be the same , we are checking with each phones ,and as no other applications are not yet available in the store
   
   

   Flashing the device

   1. Desktop setup

   The following steps are required on your desktop system in order to flash and communicate with the device.

   Setup the Ubuntu for phones tools PPA

   The PPA has the tools and dependencies to support 12.04 LTS, 12.10, 13.04 and 13.10. Add the Ubuntu for phones PPA by adding the following custom source list entry to your/etc/apt/sources.list file.

   On your computer, press Ctrl+Alt+T to start a terminal.

   sudo add-apt-repository ppa:phablet-team/tools
   
   
   
   

   Then do the following:

   sudo apt-get update 
   sudo apt-get install phablet-tools android-tools-adb android-tools-fastboot
   

   3.Device unlock

   
   If the device is already unlocked, skip to Step 4. These steps will wipe all personal data from the device.
   
   
   With the device powered off, power on the device by holding the power button + volume up + volume down.
   
   The device will boot into the bootloader.
   
   Plug the device into the computer via the USB cable.
   
   On your computer, in a terminal, run sudo fastboot oem unlock, on the device screen, accept the terms of unlocking.
   
   Boot the device by pressing the power button (pointed by an arrow with Start on the screen).
   
   
   

   Device factory reset

   
   If you get stuck in a bootloop rebooting the device after unlocking the bootloader, here is what you do:
   
   
   During the bootloop hold the power button + volume up + volume down button simultaneously to get yourself back into fastboot mode or download mode as you were previously.
   
   In fastboot mode or downlaod mode, use the volume keys to scroll to Recovery and the power button to select it.
   
   In Recovery (Android robot on his back with a red triangle), tap the volume up button and the power button simultaneously which will bring you into stock recovery. Dont hold the buttons, just tap them simultaneously.
   
   Also make sure youre holding the correct volume button. Up will be the volume key on the right.
   
   Once youre in Recovery, perform a factory reset/data wipe and then reboot your device, you should now be back to the Welcome Screen.
   
   
   

   4.Initial device setup

   
   Follow these initial steps on your device:
   
   
   If not booted, boot the device into Android
   
   Enable USB debugging on the device
   
   On Ice Cream Sandwich (version 4.0) go to Settings and turn on USB Debugging (Settings > System > Developer options > USB debugging).
   
   On Jelly Bean (versions 4.1 and 4.2) you need to enterSettings > About [Phone|Tablet] and tap the Build number 7 times to see the Developer Options.
   
   On 4.2.2, (Settings > About) tap on build number 7 times to activate the developer options menu item).
   
   On either Android version you must then enable USB debugging via Settings > Developer options > USB debugging. You will also need to accept a host key on the device.
   
   On the workstation: adb kill-server; adb start-server
   
   
   
   
   
   Plug the device into the computer via the USB cable.
   
   Depending on the installed Android version, a popup will show up on the device with the host key that needs to be accepted for the device to communicate with the workstation.
   
   Note, adb devices should not show the device as offline. If it does, unplug the device, run adb under sudo on the workstation (eg. sudo adb kill-server; sudo adb start-server), then plug the device back in.
   
   
   
   Save the version of the current image on the device, if on Android, to use as a reference to revert back to. The version can be found by going to Settings > About Phone > Build Number.
   
   
   
   

   5.Downloading and deploying image to device

   
   
   To install Ubuntu for phones on your device, you will need to run the command:
   
   phablet-flash ubuntu-system --no-backup
   Please note, this will wipe the contents of the device so ensure you have made a backup.
   This will deploy the latest build onto your device, after which your device will boot into the Ubuntu Unity shell. This step can take a very long time.

Installing Bind9 on Ubuntu

Bind Configuration

The next step is to configure the forwards addresses for bind.

Configuring internal domain

sudo nano /etc/bind/named.conf.local

then press enter

We will need to figure out our IP address range of our internal network so we can build the correct reverse zone lookup file.

Most home networks will have a 192.168.1.X or 192.168.0.X type of IP address. In my case I have a 192.168.0.X IP address network.

When looking at our IP address the part we care about is the first three sets of octets ( 192.168.0.100 = three sets 192.168.0) 

Then we just reverse them - 192.168.0 => 0.168.192

Replace linux.lix with the internal domain name you picked and replace 0.168.192  with your IP address scheme.

and make note of the names because we will need to build these files in the next few steps. 

zone "linux.lix" {
             type master;
             file "/etc/bind/db.linux.lix";
        };

zone "0.168.192.in-addr.arpa" {
        type master;
        notify no;
        file "/etc/bind/db.192";
};

Hit CTRL + X to exit out of nano
Enter Y to confirm saving changes

Building Your DNS Forward Zone

The first file we need to build is the forward zone file (db.linux.lix)

sudo cp /etc/bind/db.local /etc/bind/db.linux.lix

This will copy default zone to our zone

Now lets Edit our Zone db.linux.lix

sudo nano /etc/bind/db.linux.lix

The three most common types of DNS records are Address (A Record), Canonical Name (CNAME), and Mail Exchanger (MX). We will focus on A Record

A Record: Defines a mapping of a hostname to an IP address. This is the most common
CNAME: Defines that the domain name is an alias of another name.
MX: Defines mail servr
NS: Name Server

Replace linux.lix with internal domain name you picked
shahid.linux.lix with your internnal domain name example - user.yourdomain.ext
Change DNSserver. to your UbuntuServer Host name and put "." in end of host name as shown in above picture.

Put " ; " in front of  like these
;@      IN      A       127.0.0.1
;@      IN      AAAA    ::1

Now Maping Domain Name to IP

@      IN       A      192.168.0.101
In my case 192.168.0.101  is My internal webserver.

Now Building Reverse Lookup

sudo cp /etc/bind/db.127 /etc/bind/db.192

This will copy default reverse lookup file to our database

Now edit the file
sudo nano /etc/bind/db.192

Replace linux.lix as with internal domain name you picked as Mention Earlier
Make sure you have a "." at the end of the names.

IN is defining it as an Internet address.
PTR is a pointer record. This defines what name will be called when an IP address is looked up.

Now lets save our reverse zone file by hitting CTRL + X
Enter "Y" to confirm saving the file.

Now Start Your DNS Server

sudo service bind9 start

Now Test The DNS server

Now open Internet Protocol Version 4 properties in Windows7 or 8 or10
located in - Control PanelNetwork and InternetNetwork and Sharing Center
then click on Local area Connection Status then - > properties -> Internet Protocol Version 4

And then Put your Ubuntu Server Ip address to Preferred DNS server Box and click ok

Now Open CMD in Windows

Type ping linux.lix
Now open you Browser type linux.lix in url You will get your Web server - Web Page

For Any one Who Join Your Local Area connection can get the DNS server By puttion Your Ubuntu Server IP address to your Router DNS setting

Now you Have Your own Domain Name and Server
