Mount ISO Image in Linux

Linux fans always download Linux distributions CD/DVD ISO, and bunt it into suitable media. And we have some times to operate ISO images. In this article, I will show Linux users how to mount ISO images as a device.

Strictly speaking, Linux will regard ISO image as a loop device when you mount on a specific directory. The loop device is quite useful, for example, as you know, the localhost IP: 127.0.0.1, it's a loop network address. When you send packet to this address, the whole data will be back totally. But you can do the entire network test or build network software easily.

Well, switch to the ISO image. At first, you must make a mount point as usual. In this article, I make it called /mnt/iso. Then use mount command to mount the ISO image.

Command Line:
mount -o loop,ro -t iso9660 image.iso /mnt/iso

Now you can go to /mnt/iso directory to read the ISO image. For unmount this ISO, use follow command.

Command Line:
umount /mnt/iso

That's all.

Make CD ISOs from DVD ISO of Fedora Core 5

The Reverse Process,now.

Here is the How-To:::

1. Go to the fedora website hosting the CD isos.
2. Directly mount the CD isos one by one in deamon tools via the webaddress(suppose drive x)
3. Run "CMD" and execute the following commands:
4. Change directory to drive x by typeing "x:"
5. type "copy .diskinfo c:\cd1.diskinfo"
6. Type "tree > c:\cd1.txt"
7. Load the next iso in deamon tools and repeat the two commands above but keep changing the 'cd1' to cd2 and so on(in both commands).
8. Now after u have all the directory structure u gotta get working. load the DVD iso in deamon tools
9. Now using explorer create five folders named CD1 ... CD5
10. See the directory structure but running CMD and using the edit utility.
11. Now for each folder duplicate the contents by copying the files from DVD according to the CD structure.
12. Rename each "cdx.diskinfo" file to ".diskinfo" and place in respectibe CD folder
13. Make iso using magiciso or nero.
14. Varify the file size.
15. Any files u dont find in the DVD, copy them off by loading the CD iso
again in Deamon tools directly from the web.

I dont think,personally,you will like this method much b'coz its a pain(full)-killer and i dont think i know any method that is simpler than this.


Anyway,Good Day !

Make DVD ISO from CD ISOs of Fedora Core 5

Since things have gone multi-GB nowadays, handling one DVD is way easier then putting in six CDs one after the other,and the world is going quite this way.. so heres this tutorial.


Ok here is what you need to do.

Requirements:
1. The CD isos of Fedora core 5 ofcourse(the 1st five only, as sixth is rescue)
2. Magic ISO to edit images. or any other free alternative
3. An editor.
4. A Dvd Burner.
5. Daemon tools(makes life easier and lessens the free space req.)
6. 4 Gb free HDD space(+ the space the CD isos are taking up)

Procedure:
1. Copy the CD1 to a temp folder.(there should be 4 GB space on this drive)
2. Open Magic ISO and browse for the file.
3. From the root of the image see for a file named ".diskinfo"
4. Right click and extract on desktop.
5. Open a command promp and type "edit"(notepad doest work with this nicely, u can use textpad too)

6. Browse to the ".diskinfo" file. it will look like this:

Code:
1142397842.393345
Fedora Core
x86_64
1
Fedora/base
Fedora/RPMS
Fedora/pixmaps

7. Edit the file to look like this, basically append ",2,3,4,5" after "1" in line 4.
Code:
1142397842.393345
Fedora Core
x86_64
1,2,3,4,5
Fedora/base
Fedora/RPMS
Fedora/pixmaps

8. Save the file.

9. Drag and drop it to the open iso in Magiciso.

10. Right click on daemon tools in the taskbar and goto virtual CD/DVD-ROM>set no of deviced>4 Drives.

11. After the drives have been created left click on daemon tools again and select "Device 0" and Browse to the 2nd CD image to mount it.

12. Repeat the above step for Cds 3 thru 5. (and select device 1 thru 3 respectively). You should have cds 2 thru 5 loaded in virtual drives. check thru My computer.

13. Next, for each drive(mounted image) go to Drive:\Fedora\RPMS and select and drag and drop all files onto the magic iso window under the folder Fedora\RPMS.(alternatively add then thru magic iso, whatever, just add all). You will be asked to over write a file "TRANS.TBL" each time u drag and drop. just select yes(for explanation see page 3 of this thread).

14. After you have added all rpm files. select File>save under magiciso. rename the file to DVD from CD.

15. You are all done. Now Burn and enjoy!!!


Clean UP:
1. Left click on deamon tools and select unmount all.
2. Right click deamon tools and goto virtual CD/DVD-ROM>set no of deviced>1 Drives
3. Delete the CD isos if u want to free up space(1st check the DVD Image to be sure)
4. Delete ".diskinfo" from desktop

Note: This media will NOT pass the media check. so do no test it. If u are paranoid, then load a virtual machine and emulate the linux setup and "media-check" the individual cd ISOs there. (To make it pass the media check u need to regenerate the checksums.)

The HI-TECH Joke...

A shepherd was herding his flock in a remote pasture when suddenly a brand-new BMW advanced out of a dust cloud towards him.
The driver, a young man in an Armani suit, Gucci shoes, Ray Ban sunglasses and YSL tie (Corb), leans out the window and asks the shepherd, “If I tell you exactly how many sheep you have in your flock, will you give me one?”
The shepherd looks at the man, obviously a yuppie, then looks at his peacefully grazing flock and calmly answers, “Sure. Why not?”

The yuppie parks his car, whips out his Dell notebook computer, connects it to his AT&T cell phone, surfs to a NASA page on the internet, where he calls up a GPS satellite navigation system to get an exact fix on his location which he then feeds to another NASA satellite that scans the area in an ultra-high-resolution photo. The young man then opens the digital photo in Adobe Photoshop and exports it to an image processing facility in Hamburg, Germany. Within seconds, he receives an email on his Palm Pilot that the image has been processed and the data stored. He then accesses a MS-SQL database through an ODBC connected Excel spreadsheet with hundreds of complex formulas. He uploads all of this data via an email on his Blackberry and, after a few minutes, receives a response. Finally, he prints out a full-color, 150-page report on his hi-tech, miniaturized HP LaserJet printer and finally turns to the shepherd and says, “You have exactly 1586 sheep.”

“That’s right. Well, I guess you can take one of my sheep.” says the shepherd.
He watches the young man select one of the animals and looks on amused as the young man stuffs it into the trunk of his car.
Then the shepherd says to the young man, “Hey, if I can tell you exactly what your business is, will you give me back my sheep? “The young man thinks about it for a second and then says, “Okay, why not?” “You’re a consultant.” says the shepherd.

“Wow! That’s correct,” says the yuppie, “but how did you guess that?”

“No guessing required.” answered the shepherd. “You showed up here even though nobody called you; you want to get paid for an answer I already knew, to a question I never asked; and you don’t know crap about my business. . . ” … Now give me back my dog.”

Install IE7 and WMP11 without WGA check

There is an easy way to install the Microsoft Internet Explorer 7 without the WGA check.
As you all know the Windows Media Player 11 and the Internet Explorer 7 perform WGA checks during installation to make sure the user running the installation has a legitimate version of Windows.
More than 1 million false positive checks have been made thus far which means that many users of legit versions of Windows can’t install the IE7.

All you need to do is edit the hosts file that is in system32\drivers\etc of your windows installation and add the following line to it: 127.0.0.1 mpa.one.microsoft.com

This redirects all request to mpa.one.microsoft.com to your system.
The address is used to perform the WGA check.
Check your All Users/Application Data folder and delete the folder Windows Genuine Advantage if it exists.

Once this is done start the installation of the Internet Explorer 7 and click on Verify during the installation. The connection to the Microsoft server will be redirected to your computer and the installation continues unhindered.

The same hack works for the installation of the Windows Media Player 11 as well.

The freedom is virtual,but its fear-real

The Internet has been known to Indian public for just over a decade but the large impact it has created among this domain is visible even to a blind eye. It has been able to reach people in different walks of life and has become quite a companion in work or at home. It has ushered in the cyberspace that refers to the virtual where homo sapiens communicate and fuse using the medium of Internet technology. The Virtual World has given us almost unlimited freedom if expression,the right to express ourselves as we do in the real world. This has obvious advantages but it can also be damaging if misused. At present,there is concern about the Internet turning into the medium of fear and a clamour for legal checks. But the best filter,says Subimal Bhattacharjee,a cyber security policy expert,would be a balanced and responsible approach towards keeping cyberspace free from unwanted content.
In my view,this is very very important as there is no clear consensus about what should be a standard for online content which touches all geographical,social and cultural entities.
The freedom that i just talked about,the freedom which knows no barriers,the freedom of expression that gets a platform growing wider by each moment,the freedom that could be limited in the real world, as shown by some recent incidents as to where such degree of freedom could lead to.
An NRI posted a video of Gandhi Ji pole-dancing n stripping,titled "Time To Get Sexy". Then we can see "We hate ... ... .." communities on almost every social networking site like Orkut,Hi5,etc.
Cyberspace has given us immense opportunities and so,i think,cynical expressions should not vitilate the atmosphere so much so that all forms of surveillance and censorship rules the medium.
The responsibility lies in greater understanding,not laws and filtration by technology. We should all take lessons towards some mature online expressions.


in the tail,a few content filters for a healthy virtual world:
