Prepare Bootable Pen Drive for Windows and Linux

Now you can make boot-able pen drive for almost every Windows or Linux edition in very easy way. I will discuss Windows and Linux, one by one.

Lets talk about Windows First.
If you want to prepare boot-able pen drive, then first thing you need is boot-able ISO file of the operating system. then one of the following software, whichever fits in your need.

Installing LAMP Server on Red Hat Fedora 16

Previously I have posted about installing LAMP Server on Ubuntu. That was quite easy comparatively to what I am going to share here.
We are going to install LAMP Server on Fedora 16.
Firstly There is no single command installation I could find on the GOOGLE. We have to explicitly install every component of LAMP Server manually.
Lets start installing LAMP Server.
Lets install APACHE First.

Open terminal and type su and then enter root password to become root user for installation.
Now type: yum install httpd
This command will install, Apache server on your machine.

Installation of LAMP Server on Ubuntu (LINUX APACHE MYSQL PHP on UBUNTU)

If you are PHP developer and working on Linux i.e. Ubuntu Desktop, then you must need to have one LAMP setup on your local machine to develop and test pages before you directly update the pages to real website.

There are different ways to install APACHE, MYSQL and PHP on ubuntu desktop. I will try to mention the easiest one.
Before posting this tutorial, I have tested all these on my machine and all are working perfectly fine.

Firstly the easiest one.
In a single command, you can install Linux Apache Mysql Php stack on your machine. You need to open terminal and have to type the following command:

sudo apt-get install lamp-server^
make sure you are typing the ^ symbol also at the end.
press enter. It will ask for password. Enter your password and it will continue with installation process.

Second way, using tasksel utility.
If you want to have the feeling of ubuntu server style installation, then you should go for using tasksel utility. For this, you have to first install this.

To install tasksel, type:
sudo apt-get install tasksel
and press ENTER. Then provide your password and installation will start.
one installation is finished, now type:
sudo tasksel
and press ENTER.
It will bring up BLUE screen in the terminal with various pre-defined packages of UBUNTU. Just select LAMP SERVER and press SPACE. then press ENTER. It will install the APACHE MYSQL PHP on your machine.

Using tasksel can help you to install or un-install other variants of the server packages very easily. every time you have to type sudo tasksel and you can select the package of your choice.

Third way, little expanded one.
you have to install all three 1.Apache 2. MYSQL 3.PHP, seperately.

To install, type the following:
sudo apt-get install apache2 php5 mysql-server

this command will install all the three packages.

and in the if you wish to work with PHPMYADMIN, then to install, type the following:
sudo apt-get install phpmyadmin
this will install phpmyadmin, web based interface to manage MYSQL Server Databases.

Installing Red Hat Fedora 16 without Internet / Network

Al last, I am able to find how to install Red Hat Fedora 16 without Internet Connection or Network Connection. It was very tedious task to find the solution. Tried many solutions, but none of them was working.
So, at last go through few forums, I was able to get the solution which I am going to share here with you.

You need to download the DVD of latest Fedora edition i.e Fedora 16.
Then you need Fedora Live USB Creator latest edition.
A pendrive of 4GB. Personally I will suggest use 8 GB Pen drive.
Use your LIVE USB Creator and to transfer the ISO to Pen drive.
Transferring may take some times one hour also.
After successful transfer, reboot your system
Make changes in BIOS to boot from USB.
Once changes made in BIOS, your system will boot from Pen Drive.
System will show you 2 options :
1. Install / Upgrade Fedora 16
2. Troubleshooting.

Select first option and do not press ENTER. Press TAB on your key board.
It will show you command prompt with command already written.
Do not change / remove here.

Just enter SPACE from keyboard and type the following as it is:
repo=hd:LABEL=LIVE:/

and then press enter. Now you will not be asked to connect to internet or network during the installation. You can enjoy installation without internet from your pen drive.

Make sure on PACKAGE SELECTION SCREEN, just select "installation repo". If you select any other option also, that will require internet access.
I hope this may help many people who do not have internet but want to use FEDORA 16.

THis tutorial may help those also who are trying to install from DVD. in that case they don't need LIVE USB Creator. Just burn the DVD with ISO. Insert the DVD and boot from the DVD. Then same options will be followed as mentioned above.

If you are stuck somewhere, you can ask me..

Save your modem / router from DND MITM Attacks

B8HXUZ8BUZ98
Recently I started facing a problem with internet connection. I was not able to open yahoo.com, microsoft.com. Instead of these two sites, Ukranian Site was opening. I thought that these 2 sites are hacked. Then I tried opening both sites on my iPhone with GPRS. It worked properly. Both sites were opening perfectly on GPRS. Then I realised that the problem is with my PC / Network. Then I tried my desktop. Same result. None of the sites were opening there too. So Its not the problem with my laptop or desktop. Its the problem of the network. Then I investigated my WIFI Router (Belkin). Checked the settings every thing seemed to be fine there. Still I reset the router and configured it again. But still no luck with the sites. these were not opening.redirecting me to Ukranian site. Then I decided to get into wired modem (beetel). Here was the problem. I was not able to log in to my modem. I was surprised. I had never changed the default username and password. So, I got it that problem is with my wired modem. Somebody has hacked into my modem and password is changed.Then I decided to reset my Wired Modem and configure it again. Thanks to Airtel Engineer who left the settings document for my modem. After resetting the modem, I tried both sites, Now these were opening.

After 4 days again same thing happened. I directly reset my modem. Didn't bother much. But when for the 3rd time, it happened. I decided to find out the solution for this. Somebody was changing my modem's password again and again and I was not able to do anything besides resetting it again and again.
 Then I followed the following steps:

1. It is better to change the default password of the modem.
2. Try to keep backup of the modem's working configuration.
3. Use OpenDNS Servers instead of using ISP's DNS.
4. Try to avoid DHCP. Keep it disabled and manually assign IP Addresses to machine.
5. Try to implement MAC Filtering feature if available.It will give you extra security.
6. Disable TFTP and TElnet services for WAN.

These few things worked for me.

How to prepare Bootable USB Drive / Pen Drive for Windows 7 and Windows 8 Developers Preview

Now a days, DVD / CD are getting out of fashion as installation media. Netbooks don't even have these cd/ dvd drives. Every one prefers to use USB Drives. So, do I. But in my case, I have to use USB Drive because DVD Drive of my laptop is not working any more and I don't want to spend money on my laptop.
So I learned how to prepare boot-able USB drive to install Windows 7 and Windows 8. Same thing I will try to share with you in easy manner.

First of all, I will suggest you to get one 8 GB pen drive. I saw many tutorials on the internet which generally says you can use 4 GB pen drive. But whenever I tried using 4 GB drive, every time few files are left for copying. So, I got 8GB pen drive.

Start with inserting pen drive into your system and follow the procedure mentioned below:


1. Format your pen drive with NTFS partition.
2. Start CMD in your system as administrator.
3. Type DISKPART and press ENTER.
4. This command will show you all the drives attached to your system including pen drives.
5. Select disk of your pen drive. In my case, pen drive is disk 1. and generally it will disk 1. so you have to type SELECT DISK 1 and press ENTER.
6. Then type CLEAN and press ENTER.
7. Then type CREATE PARTITION PRIMARY and press ENTER.
8. To view the list of partitions, you can type LIST PARTITION and press ENTER.
9. Now type SELECT PARTITION 1 and press ENTER.
10. Type ACTIVE and press ENTER.
11. Now we have to format the pen drive with NTFS file system again. So, type FORMAT FS=NTFS and press ENTER.
FORMATTING may take some time. In my case, to format 8 gb pen drive, it took 4-5 minutes.
12. Once formatted successfully, now type ASSIGN and press ENTER.

13. Now type EXIT and press ENTER.
ALL ABOVE MENTIONED PROCEDURE IS AVAILABLE IN THE FOLLOWING SCREENSHOT
NOW you will out of the DISKPART utility of the windows 7.
Now don't close the CMD window. We still need it.

Now minimize the CMD window and insert your windows 7 or windows 8 disk. If you are ISO image then just extract it some where on the hard drive.
1. Now open your CMD window again.
and navigate to windows 7 or windows 8 folder on your hard drive if you have extracted the image on your system or just navigate to cd/dvd drive.
2. Then get into BOOT folder. Type CD BOOT and press ENTER.
3.  Now type BOOTSECT.EXE /nt60 k: and press ENTER.
HERE K: IS THE DRIVE LETTER FOR MY PEN DRIVE. IN YOUR CASE, IT MAY BE DIFFERENT. SO WHICHEVER IT IS, USE THAT ONE.
4. Now copy all the contents of the dvd or windows folder ( which you recently extracted) to pen drive as it is. Make sure there shouldn't be any thing left which is not copied to the folder.
ALL THESE STEPS ARE MENTIONED IN THE SCREENSHOT BELOW.

NOW YOUR PEN DRIVE CAN BE USED AS INSTALLATION MEDIA FOR WINDOWS 7 OR WINDOWS 8 WHICHEVER YOU HAVE COPIED TO YOUR PEN DRIVE.

Next thing which is important is that you have to select an option from BIOS to boot from pen drive.
Only then you can boot from any usb media. otherwise you can not. If your BIOS doesn't support booting from USB, then try to google for firmware update of your bios.
