If detected use lsusb -v, to find the product id and vendor id of the modem.

In my case I am using Huawei EC168C – the vendor id is “12d1″ and product id is “1446″.

Open the terminal and follow the instructions

#sudo gedit /etc/udev/rules.d/15-huawei-115x.rules

Now paste the following content as follows and save.

SUBSYSTEM==”usb”,
SYSFS{idProduct}==”1446″,
SYSFS{idVendor}==”12d1″,
RUN+=”/lib/udev/modem-modeswitch –vendor 0x12d1 –product 0×1446 –type option-zerocd”

Save the file. Unplug and plug the modem. Now right click the network icon , goto Mobile Broadband and click Edit. Enter the phone and username.

In my case I am in Zantel network. The phone number is #777 and username is @zantel.com. Click the network icon again and click the detected modem to enjoy surfing.

Ruby on Rails is a web application programmers based on Ruby. It helps the programmers creat best web applications easily.

Here are the steps to set up Ruby on Rails in your Ubuntu or Debian based systems

Step 1: First step is to install some inportant packages that are recured,

sudo apt-get -y install build-essential libssl-dev libreadline5-dev zlib1g-dev

Step 2: Install ruby

RUBY="ruby-1.8.6-p111" //Current stable version

wget ftp://ftp.ruby-lang.org/pub/ruby/1.8/$RUBY.tar.gz

tar xzf $RUBY.tar.gz cd $RUBY

./configure --prefix=/usr/local --with-openssl-dir=/usr --with-readline-dir=/usr –with-zlib-dir=/usr

make clean

make

make install

make install-doc

make clean will clear any make files in that folder, previosly created that was configured without right options Checking whether ruby is installed properly

ruby -ropenssl -rzlib -rreadline -e "puts :success"

Step 3: Install Gem

Gem is a installer similar to apt, for ruby and ruby related packages

RUBYGEMS="rubygems-1.0.1" //Current stable version
wget http://rubyforge.org/frs/download.php/29548/$RUBYGEMS.tgz
tar xzf $RUBYGEMS.tgz
cd $RUBYGEMS
/usr/local/bin/ruby setup.rb
	

Step 4: Install Rails

gem install rails //This will install rails successfully.

Or gem install <paths to rails gem file>

Main Errors during Installation:

Error 1:

/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require’: no such file to load — zlib (LoadError)

using the following step for configuring ruby, that is before make, will remove this problem

./configure --prefix=/usr/local --with-openssl-dir=/usr --with-readline-dir=/usr –with-zlib-dir=/usr

Error 2:

no such file to load — mysql

undefined symbol: rb_Digest_MD5_Init – /usr/local/lib/ruby/1.8/i686-linux/digest/md5.so (LoadError)

Installing the mysql dev package and mysql library for ruby will clear this error,

sudo apt-get install libmysqlclient15-dev

sudo gem install mysql

There are both soruce packages and ubuntu build deb packages in the above link…
But inturn dont mistake that installing XMMS2 from the repo is the XMMS player. After intallation there may be some combatibility problems. But there wont be any probleming in playing songs.

The system that has source contents to be shared should have Samba server, (That can be installed in course of the procedure how to share). And the remote system that wish to access the source contents should have the Samba client. Samba client will installed be default in ubuntu, if not install it with the command

$sudo apt-get install smbclient

Here comes the procedure how to share.

Soruce Side

1. On the source system login to ubuntu, right click on the folder you wish to share and select ‘Sharing Options’.

2. In the Dialog box that apears select ‘Share this Folder’ check box, you will be prompted to install a service. Clicking on Install will open synaptic package manager and install the Samba Server packages.

3. On successful Installation of the packages, the part in the server side is over.

   This will create a share automatically in Samba server on the the username you have logged in (here ‘rosario’) with its password.

Destination Side

1. Check whether the smbclient package is installed, if not install it with the above command.

2. Use the command like

$sudo smbclient \\\\192.168.1.33\\photos -U rosario

• where rosario is the username of the source system,
• 192.168.1.33 is the IP address of the source system
• photos is the name of the folders shared in the source system(In small characters)

3. The above command first will prompt the local system password as sudo is used. And then it will prompt for the password of the remote samba server for the username rosario
4. On giving the right password, it will take to the samba promt.

Smb: \>

Some usefull commands

• help- To know all possible commands
• dir- To list out all the shared directories, or contents inside the current directory
• cd- Change Directory
• get- To copy a specified file from the source system to the local system
• put- To copy contents from local system to the server system

Enjoy Easy File Sharing With Ubuntu…

Switch to root using ‘su’ command and execute ‘grub’ command in terminal/konsole. Prompt will change to ‘grub>’
execute md5crypt to generate password hash.

grub> md5crypt

it will prompt you for password, enter the password which you are going to set for GRUB. it will display encrypted password hash.

Password: *******
Encrypted: $1$X2jZi$KeCC6NuRp0BJDt32jCvnw0

note down encrypted password hash or copy it and exit grub mode using the grub command.

grub> quit

Now edit the
edit /boot/grub/menu.lst file and insert encrypted password above the “title” lines or insert near commented examples of password line.

password –md5 <password-hash>

But i could open them in terminal with sudo. So i restarted my lap. After booting in, my hardy displayed a message like

Loading, pease wait…
Kinit: name_to_dev_t(/dev/disk/by-uuid/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)= sda(8,8)
kinit: No resume image, doing normal boot…

After which, i will get a login message, which would login to shell.

I tried so many things, i could solve the problem. I switched on my desktop and connected net and went to IRC to #ubuntu channel for help, but in vain. And then googled so long to get so many solutions but none of them worked.

Solutions were,

1. $fdisk -l | grep swap

$swapoff /dev/sdax

$mkswap /dev/sdax

$update-initramfs -u

1. $sudo aptitude install update-usplash-theme usplash-theme-ubuntu

$sudo update-usplash-theme usplash-theme-ubuntu

1. $sudo apt-get install ubuntu-desktop

None of the solutions worked, in IRC only one person gave a response, he too told to use a rescue cd. While googling i learned few things,

What is Resume Image?

Resume image is nothing but a file that stores the state of the machine while shutting down or suspending and is kept in the swap space while shutting down or suspending and gets back to the same state when rebooted of resumed.

So finally after trying so hard last my patience and decided to reinstall, took the Ubuntu 8.04 LTS dvd and installed it over night. After installing it and all my required packages from net, i say the clock it was 5.30 am. Went to bed…

Hi viewers do you have solution….

Step 1: Creating Virtual hard drive.

$sudo VBoxManage internalcommands createrawvmdk -filename ./WinXP.vmdk -rawdisk /dev/sda -relative -register

You will get a “RAW host disk access VMDK file ./WinXP.vmdk created successfully.”

Step 2: Adding the Virtual disk file to the Virtual Box.

Open VirtualBox and choose the menu File->Virtual Disk Manager and in the window that opens click on the Add option and choose the recently created vmdk file (WinXp.vmdk)

Step 3: Creating a New Virtual Machine

Click on the New option and in the Create New Virtual Machine wizard, click Next

Enter the OS Name as WinXP and OS Type as Windows XP, and Click Next

Select the Memory based on the availabilty. In my case i have 2 gb Ram and so i selest 330 mb. And Click Next

Here comes to select the Virtual Hard drive file. Click on Existing option

Select the recently created vmdk file. (WinXP.vmdk)

Click Next and then Finish option.

Step 4: Editting the Settings of the Virtual Machine

Select the recently created virtual machine (WinXp) and Click on the Settings page. And enable Audio, Serial Ports, USB ports, CD/DVD drive as host cd/dvd drive, etc

Goto Shared Folders option and select a shared folder created some where previously (here i have selected /tmp/VirtualBox/SharedXP, which i created previously)

Now select you Start option, and for your surprice you will see your grub menu…

Note: Here in grub, the first option is the ubuntu which iam already in, its not adviced to select it again, select the Virtual OS type you have choosed already.
