This is the sequel of my post hacking the ROOT
Here i would like to write about a new technique through which we can hack into the root.
This does not have limits... i mean to say this method can be used even if the grub of any system is locked down...
But both my methods the former one in the previous post and the one that i will present here all need physical access to the system...!!
This method requires the live cd.. preferably Ubuntu... since its simple
- Insert the live cd and boot from the cd.
- You can choose the option " Try ubuntu without any changes to your system"
- you need not have ubuntu installed on your harddrive.. u just need to boot it live.
- let ubuntu boot up normally.... now go to System->Administration-> Users and Groups in the menu bar above.
- you will have a "user settings" window poping up
- just select root , click on properties and set the password by hand.Finally press ok
( sometimes you will also have to unlock , if you are not able to select root )
- Now Shoot open the terminal.type su , it will ask for the password you just created.
- Type fdisk -l in the terminal window. This will display the list of partitions on the harddrive. we are looking for a linux partition here.
- next my linux drive here is /dev/sda2 or /dev/sda3 you will have to mount the partition. since i have two linux installed on my disk, let me work on my sda2 partition
- lets create a folder to mount type mkdir /media/linuxpartition to create a directory.
- now type mount /dev/sda2 /media/linuxpartition to mount the partition.
- Now lets change the root type chroot /media/linuxpartition for my example here.
- now you should have the command prompt symbol changed as shown below
- Type passwd and enter the new password, and there you go... you have just changed the password for your linux root.
- type reboot to restart the machine and login with your new password.. and enjoy...!!!

Readers, Still the release of the jaunty is in April already the waves of the next release of ubuntu 9.10 code named Karmic Koala.. is scheduled for this october.
Ubuntu is sticking on to its six month release cycle...
With this Karmic Koala the plans are to introduce ubuntu series into cloud computing , the most happening topic today...
And with the desktop... and netbooks plans are to reduce the boot time from 25seconds to much lesser.... and i dont wanna take a guess this time.Also they are planning to improve the theme.. and the boot screen...
well there are lots to come..and lot more in reserve...
more you can read at Mark's post..Karmic Koala

While those who disparage Linux might have a point with regard to its appearance or the lack of drivers, they fail to see the larger issue. Linux is a success because it represents an alternative in an environment that is designed to help the powerful eliminate alternatives.
So often, the defense of Linux involves a price argument. More important than the free price is the freedom Linux and other GPL software represent. Lately, I have noticed a lot of bloggers disparaging Linux-based operating systems for all kinds of reasons, from aesthetics to business strategies.
Of these, Linux Hater's blog stood above the rest, and though his criticisms are generally valid, he completely misses the mark. Though we should never avoid holding Linux-based operating systems to the same standards as proprietary platforms, we must recognize that any shortcomings are minor in the context of all of the successes of Linux and open sourcesoftware.
Just check the blog, they make some really valid points.

It seems that every few months, companies come up with ways to cram more memory into flash drives -- the memory technology that makes things like iPods tick. In a few years, however, flash drive memory development as we know it will hit a brick wall and new techniques will be needed to increase capacity. That's where graphene comes in.
A single layer of graphite, which is used in the common pencil, graphene is composed of carbon atoms and looks like tiny chicken wire. In this configuration, it is an exceptionally strong material that efficiently conducts electricity.
Its circuitry can also be built at much smaller sizes -- less than 10 nanometers compared with the current 34-nanometer circuitry of the smallest flash memory devices. And perhaps most importantly, graphene memory can be stacked in three dimensions rather than arrayed in two, allowing for considerably more memory to be crammed into a single chip.
Wow!, in such a case- a 1TB iPOD would be of the size of the present day iPOD nano 3G!

Despite all the hyperbole over Apple's "world's fastest and most innovative browser" claim, there's a lot to genuinely like in the beta of Safari 4 -- along with a few minor quibbles.
Apple boasts that the Nitro JavaScript engine in Safari 4 runs JavaScript 4.2 times faster than Safari 3, up to 30 times faster than Microsoft's Internet Explorer 7, and more than 3 times faster than Mozilla's Firefox 3. It loads HTML pages three times faster than IE 7 and almost three times faster than Firefox 3.
While we're all hopped up on the speed-claim bandwagon, Apple says Safari 4 is the first browser to pass the Web Standards Project's Acid3 test, which examines how well a browser adheres to CSS, JavaScript, XML and SVG Web standards that are specifically designed for dynamic Web applications. Cool. (But some other browser makers aren't particularly interested or concerned with the test.)
Amidst all these claims there's that element of thumbs down..
At first glance, Safari 4 for Mac OS X appears remarkably similar to Safari 3. Now, though, there's a little bug icon in the right side of the toolbar for reporting bugs, the reload button has disappeared (but is now at the end of the URL's address field), and the tabs are at the top -- above the address bar in the spot that used to be taken by a page's title. It's a little like Chrome, for those who've tried outGoogle's new browser.
At first, the new tabs are painful, so much so that I went looking for Safari 3 ... and realized my machine ditched it in favor of Safari 4. Sure, I could have snagged it via Time Machine or simply downloaded it, but I pressed on.
The net result of the new tabs, however, is that the typical toolbar area takes up about 25 percent less space. Now, instead of four rows of tabs, bookmarks, address, and title fields, there are just three rows. It gives you a bit of extra vertical space for Web page content. Handy.
(Is it all in preparation for a screen-constrained Mac netbook, perhaps?)
The Cover Flow and Top Sites
It didn't take long for Apple to get hammered with criticism over a couple of its eye-candy features, Cover Flow and Top Sites, but those critics just don't understand -- humans are a visually oriented species, and these two features have the power to make browsing better than ever before.
Here's something that you'd have met with. Sometimes when we accidentally close windows that we don't mean to -- or close a window that takes out a series of tabs -- and finding the page that we want to return to in a long history list can be hit or miss (mostly miss). Then we end up googling again until we eventually find my way back. Safari 4's Cover Flow history feature changes everything.
Unlike the not-so-useful Cover Flow in iTunes and on the iPhone, Cover Flow for history is amazing. It gives you a set of pictures of the Web pages you've visited in chronological order, making it surprisingly easy to recognize the page you want to return to.
Apple also has two additional features available from the History drop down menu: Reopen Last Closed Window and Reopen All Windows From Last Session. These options can help you return to the sites you want if you accidentally close a window (or make it easier to snoop on others).
In addition, Apple has improved the address field by making it smarter -- start typing an address and it automatically completes Web addresses by displaying an easy-to-read list of suggestions from Top Sites, bookmarks and browsing history.
On the downside, Safari 4 doesn't boast the plug-in capabilities that come with Firefox 3, and Apple hasn't indicated much interest in fostering a plug-in community. PC users, though, might appreciate the new Windows-native look of their version of Safari, which uses standard Windows font rendering and native title bar, borders and toolbars.
For previous Safari 3 users, Safari 4 is definitely a worthy upgrade. And so far, over a few days and gobs of pages, it hasn't crashed once.
