Post installation

After a successful installation and boot to the newly installed Ubuntu Lucid with out problem, now it’s time for the post-installation. You might consider to create a user if you want, login as root with your previous password:

Step 1. You will need to edit your hosts file

So I want to install Ubuntu Linux for my other system without using a cdrom, but I dont want to do it on that system, instead of that I want to install it via my current working ubuntu desktop that Im using right now.

Actually I want to build a firewall system complate with hotspot gateway and freeradius. But for now lets start with the basic installation first.

You could follow the instruction from ubuntu help community by Curtis Lee Bolin : Installation From Linux or you can continue to read it from here because I made a little modification for the installation method and I add the instruction for the post-installation and how to setup a firewall base system.

How to install without CD

You can install Ubuntu directly from Ubuntu using debootstrap. Debootstrap installs some essential packages in a directory for use with chroot. Note that the essential packages does not in itself make the system bootable. It just installs what you need to chroot to that directory and use apt-get to install other packages witch makes ubuntu usable.

Step 1. First turn off you computer and plugin your hard drive to it, after turn it on back then check that you have debootstrap installed if not, then you should run the following command below:

# sudo apt-get install debootstrap

(NOTE: if you want to install a newer release than your current system, you normally need to install the backported debootstrap version, see: UbuntuBackports)

Step 2. Partition device and make a file-system, to make it more easy, I use cfdisk to create partition for the other drive.

We will assume /dev/sdb is the storage device for your fresh install. I use my thumbdrive to show you an example how to partition the other drive for another system to setup an installation of ubuntu linux from your current ubuntu desktop.

Remove former partitions and create the new on.

# sudo cfdisk /dev/sdb

cfdisk (util-linux-ng 2.17.2)

Disk Drive: /dev/sdb
Size: 2056257536 bytes, 2056 MB
Heads: 64   Sectors per Track: 62   Cylinders: 1012

Name        Flags      Part Type  FS Type          [Label]        Size (MB)
——————————————————————————
sdb1        Boot        Primary   W95 FAT32 (LBA)                   2056.00

[ Bootable ]  [  Delete  ]  [   Help   ]  [ Maximize ]  [  Print   ]
[   Quit   ]  [   Type   ]  [  Units   ]  [  Write   ]

Use your arrow key to the [ Delete ] option to remove your partition on the other drive:

Name        Flags      Part Type  FS Type          [Label]        Size (MB)
——————————————————————————
Pri/Log   Free Space                        2056.00

[   Help   ]  [   New    ]  [  Print   ]  [   Quit   ]  [  Units   ]
[  Write   ]

Create new partition from free space, then you will see your drive is empty, now select [ New ] to create your new partition and select [ Primary ] :

Name        Flags      Part Type  FS Type          [Label]        Size (MB)
——————————————————————————
Pri/Log   Free Space                        2056.00

Size (in MB): 1500

You need to enter new size limit for primary partition, press backspace then enter the size yo want, for example I use 1500MB and 500MB++ for the extended and swap partition.

Now create the rest of your free space as an extended and swap, to change type of your newly created partition navigate to [ Type ] press Enter and select 83 for linux and 82 for swap.

Name        Flags      Part Type  FS Type          [Label]        Size (MB)
——————————————————————————
sdb1        Boot        Primary   Linux                             1499.34
sdb5                    Logical   Linux swap / Solaris               556.67

and select your primary partition as bootable by press the option [ Bootable ]. The write down your partition and quite cfdisk.

Are you sure you want to write the partition table to disk? (yes or no): yes

then [ Quit ] and start to make the file-system

# sudo mkfs.ext4 /dev/sdb1

Step 3. Mount that new partition.

# sudo mkdir /mnt
# sudo mount /dev/sdb1 /mnt

Step 4. Create the new install.

# sudo debootstrap lucid /mnt

Step 5. Copy files to the new install to keep your repositories

# sudo cp /etc/apt/sources.list /mnt/etc/apt/

Step 6. Chroot to your new install.

# sudo mount –bind /dev /mnt/dev
# sudo mount -t proc /proc /mnt/proc
# sudo chroot /mnt /bin/bash

Step 7. Upgrade the new install.

# apt-get update
# apt-get install language-pack-en-base

Note: I install the language-pack-en-base before upgrade to avoid perl warnings as shown below.

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = “en_US.utf8″
are supported and installed on your system.
perl: warning: Falling back to the standard locale (“C”).
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

then continue with :

# apt-get upgrade

Step 8. Install Grub and Linux Kernel.

# apt-get install grub-pc linux-image

Step 9. set root password.

To set a root password.

(NOTE: You must at least set a root password if you aren’t adding a user)

# passwd

It should now be safe to reboot, you may want the next few things.

Step 10. If you want to access it with ssh after reboot.

Use vi or install nano to edit /etc/hostname.

Remove anytext in this file and add the hostname you would like.

# vi /etc/hostname

yourhostnameyouwant

and then edit /etc/network/interfaces

# vi /etc/network/interfaces

Add this lines to /etc/network/interfaces. This will start eth0 at boot and request an ip with dhclient.

auto eth0
iface eth0 inet dhcp

Next you need to install ssh

# apt-get install ssh

Turn off your computer, remove the new installation drive and plugin to the other system, and bootup the system. If you want the Ubuntu Gnome desktop, continue with Step 11, but if you want to setup a firewall base system, so just skip the Step 11 and Step 12, so it safe for you turn off your system and boot the drive from other system.

Step 11. Install ubuntu-desktop.

# apt-get install ubuntu-desktop ubuntu-standard

Step 12. Reboot and keep those fingers crossed.

# sudo halt or sudo reboot

To be continue on Part 2

Last time I posted a tutorial about to setup your-free-domain.co.cc, if you don’t have any of this free domain name account, you can get it by using this search form to find out which name you like, after that proceed to registering your new account.

This domain is free to use for personal purpose but they will charge you for business at minimum price at $3 per domain name, but if you make a donation to them about $5, you can have around 100 domain name, normal account will get about 4 domain only.

After completing How to setup your free domain name in Blogger – Part 1 process, to make your free domain working with Blogger all you need to do now is login to your Blogger account and start doing the next procedure.

If you feel uncomfortable with image size, you can maximize it by click the maximize button located on the top left corner of the images .

Wokeyy.. let’s do it…

Step 01
At your Dashboard click at “Setting” link on your Blog.

Step 02
At the navigation menu “Setting” tab, click the sub menu “Publishing”.

Step 03
Then you will see the “Custom Domain” link, click on it.

Step 04
Then you will see the “Switch to advanced settings”, for more infos, if you don’t have any domain yet, you can purchase it through Blogger.

Step 05
Key in your domain name in the text box, remember that you should include the “www” subdomain before your top level domain name, otherwise Blogger will reject your request if you put naked domain name e.g. kitablinux.co.cc. By the way if you like to use a different subdomain like blog.kitablinux.co.cc, you can do it by adding up first the CNAME at your co.cc domain hosting.

After that key in the “Word Verification” text and click “SAVE SETTING” button.

Step 06
After doing all the above successfully, now you need to redirect your domain name, click the checkbox to redirect your domain, but please make sure first that you already Create ‘A’ NAME records for your naked domain as I did mention in the Part 1 of this tutorial, if not you should check for it first or your redirection won’t work at all.

Enter your “Word Verification” in the textbox and click SAVE SETTING button to proceed, after completing all the steps above now try to view your domain either using full web address with subdomain e.g. “http://www.kitablinux.co.cc” or naked domain e.g. “http://kitablinux.co.cc”.

If you new to Ubuntu Linux, sometime you might face a problem in configuring display in Ubuntu Linux, it’s might cause of un-supported monitor or lcd on your system.

To solve the problem you could done it by following the instruction below using the xrandr. First open your terminal from your desktop, go to Ubuntu Main Menu button > Accessories > Terminal, and type the following command  to find your default display adapter:

# xrandr

# Screen 0: minimum 320 x 240, current 1280 x 800, maximum 1280 x 800

default connected 1280×800+0+0 0mm x 0mm (you’ll see the default word that I just bold it, is my default display adapter, but it might different with your’s)

1280×800       50.0*

1024×768       51.0

960×540        52.0

840×525        53.0

800×600        54.0

800×512        55.0

720×450        56.0

680×384        57.0     58.0

640×512        59.0

640×480        60.0     61.0

576×432        62.0

512×384        63.0

400×300        64.0

320×240        65.0

# cvt / gtf 1280 800 60 (note: you can use cvt or gtf, but dont type both just one) i.e # cvt 1280 800 60

then you will get the following messages

# 1280×800 59.81 Hz (CVT 1.02MA) hsync: 49.70 kHz; pclk: 83.50 MHz

Modeline “1280x800_60.00″   83.50  1280 1352 1480 1680  800 803 809 831 -hsync +vsync

Then to add new mode run the following command :

# xrandr –newmode  ”1280x800_60.00″   83.50  1280 1352 1480 1680  800 803 809 831 -hsync +vsync

after that add your desire mode to the default display adapter of yours by using the command line option below:

#xrandr –addmode default “1280x800_60.00″

And to set up your screen display with new resolution, run the command below:

# xrandr –output default –mode 1280×80

Before and after screenshot:

800×600

1240×800

My actual problem is :

1. the UTP cable on POE Adapter is not working to transmit data via it own UTP cable, to buy a new one it cost about $25-$60 buck(RM80 – RM200), but why spending when you can still use the POE Adapter as power supply, except for the broken UTP cable on the POE Adapter.
2. the current UTP installed with Linksys WAP54GPE with RJ45 PCB Socket attached on it is not working too.

the power is there but not the network connection

My Solution :
Splitting 1 UTP cable into POE connector and networking cable. At the first end of the UTP cable clamped as normal straight cable, and the second end we split it one as data cable and the other as power supply cable. So pins 1,2,3 and 6 will be connected to the switch.

like this one

We see that the TX (transmitter) pins are connected to the corresponding RX (receiver) pins, plus to plus and minus to minus. You can also see that both the blue and brown wire pairs on pins 4, 5, 7, and 8 are not used in either standard, but actually it was used as power transmiter between the POE Adapter and WAP54GPE Access Point.


What you may not realize is that, these same pins 4, 5, 7, and 8 can be used as data or network cable as well if we going to split one UTP cable to be connected to two NIC on the same computer system such as linux pc based router/firewall, so for pins 4,5,7 and 8 are used as power supply pins.

If you have any question, do not hasitate to post it on our comment form.

Before I go on, a bit of a disclaimer: Following the instructions below may not provide you with results that fit your particular needs. If you have specific and detailed requirements, see the DRBL documentation. If you would like to hire LightCube Solutions to provide assistance in setting up a Clonezilla solution for your organization, send an email to info@lightcubesolutions.com.

The Steps

1. Install Linux

You’ll need a Linux machine to run your Clonezilla services. These instructions were successfully tested on Ubuntu 9.04 and 9.10 and Debian 5. DRBL will also run on Fedora.

2. Install DRBL

First off, open up a Terminal. In Ubuntu and Debian, this is located in ‘Applications -> Accessories -> Terminal’. If you have sudo configured, you can change to super-user access by typing:

sudo -i

Otherwise, use the root password with the following:

su -

Next, add DRBL’s GPG key to your system:

wget http://drbl.sourceforge.net/GPG-KEY-DRBL 

apt-key add GPG-KEY-DRBL

Update your apt configuration so that you can install software from the DRBL guys:

cp /etc/apt/sources.list{,.bak}echo "deb http://drbl.sourceforge.net/drbl-core drbl stable" \  >> /etc/apt/sources.list

Finally, install DRBL:

apt-get update 

apt-get install drbl

3. Configure a Network Alias

DRBL requires that you have two network interfaces. We can get around this by adding a virtual interface:

cat >> /etc/network/interfaces << "EOF"auto eth0:1iface eth0:1 inet static   address 192.168.222.1   netmask 255.255.255.0EOFifup eth0:1

To verify that you have set up the alias properly, type:

ip addr show eth0 | grep eth0:1

You should see something like this:

inet 192.168.222.1/24 brd 192.168.222.255 scope global eth0:1

4. Configure Your New DRBL Server

Run the following two interactive commands (note that this will require an internet connection and may take some time):

/opt/drbl/sbin/drblsrv -i/opt/drbl/sbin/drblpush -i

Congratulations! That’s it, you have a DRBL/Clonezilla server ready to create and deploy custom images. All you need to do to start cloning is run:

/opt/drbl/sbin/dcs

Then, boot up your client machines using PXE. See, that wasn’t too painful…

It is so simple and quite easy actually, because all the guides was writen at co.cc it self, and what you need to do is follow it exactly as it shown.

But for now let me show you from the guides it self.

How to setup Blogger for my domain?
