How to install VLC in FEDORA 18 ?

On the same lines as I installed Chrome :

su - 

cd /etc/yum.repos.d/

wget http://pkgrepo.linuxtech.net/el6/release/linuxtech.repo

yum install vlc

How to find if latest kernel version is running on my Linux system?

Simply type in these commands and the result in both the cases should match.....


rpm -qa kernel |sort |tail -n 1

uname -r

Note: If you got kernel update or run older kernel than newest installed then reboot:

reboot

Output of each commands version numbers above should match....for example in my case the out put is shown as below :

[duqu@localhost ~]$ rpm -qa kernel |sort |tail -n 1

kernel-3.6.10-4.fc18.x86_64

[duqu@localhost ~]$ uname -r

3.6.10-4.fc18.x86_64

Upgrading Fedora 17 to Fedora 18

1.   Like me so many of you would have been waiting for the final release of Fedora 18 spherical cow...but at the same time when u see it released u have so many links to move around on how to upgrade from 17 to 18 but u keep ending up with previous one....i went through the same for past hour...:-)

2.  The only set of commands Fedora 17(only) users need to put in are these :

Reach the Root first with the password ie 

su -
*******(ur password)
su -c 'rpm --import https://fedoraproject.org/static/DE7F38BD.txt'


su -c 'setenforce Permissive'

su -c 'yum update yum'

su -c 'yum clean all'

su -c 'yum --releasever=18 --disableplugin=presto distro-sync'

su -c 'rpm --rebuilddb', or rpm -qa will not work due to a upgrade of rpm

3.   For me the upgrade is around 1.6 G as seen in the screen shot below :

4.   Mine is upgrading on way....another few hours should be ok....:-) all the best for your upgrade

Apple Needs a Doctor : Bitten by JAVA - 2

1.    The Flashback fiasco,as discussed in brief here, was the catalyst for one of the most meaningful decisions Apple made in order to beef up OS X security ie Removing JAVA. "Flashback both led to Apple removing Java from their default installs, and prompted them to release a dedicated cleanup tool," security researcher (and former security engineer for Obama for America) Ben Hagen told Ars. "When an OS vendor releases a dedicated cleanup tool, you know things are bad.The removal of Java was a very Interesting decision and de facto statement by Apple. Java on user systems has become a notorious vector for exploitation; with new, remotely executable vulnerabilities coming out several times last year," Hagen said. "Removing Java both simplifies Apple’s position and provides a safer default state for its users."[Source : http://arstechnica.com/].

2.    Another key decision taken by apple apart from disowning JAVA was endevor to signed security model for apps ie restrict the origin of third-party apps installed on the system, therefore protecting the user from inadvertently installing apps from malicious or unknown sources.Called Gatekeeper, this feature required Apple's developer ecosystem to either sign their apps with a registered certificate—holding them at a higher level of responsibility for when things go haywire—or selling their wares through the Mac App Store and giving Apple its 30 percent cut. [Source : http://arstechnica.com/].

3.   Java is a veri popular program and is used by millions of users worldwide in Windows, Mac and Linux operating systems and in mobile and television devices. It is this popularity that has made it a favorite target of the hackers.So today when we cannot surf without enabling JAVA.....apples decision is indeed a tough step....for those of you who do not realise the importance of JAVA...just try surfing the web disabling JAVA scripts in your browser...u will be surprised you will be prompted at every step to ensure a successful loading of most of the web pages....In fact the U.S. Department of Homeland Security advised computer users to temporarily disable or uninstall Oracle Corp's Java software, stating that a serious flaw in the software could make the system vulnerable to hacking.The warning came in an advisory posted on the department’s website amid the escalating fears and warnings from the net security experts about a flaw in Java Runtime Environment (JRE) 7 and earlier versions that allows the hackers to install malicious software and malware on computers.The vulnerability is so dangerous that the Department of Homeland Security's Computer Emergency Readiness Team urged the people to stop using the software immediately to mitigate damage.Source : [http://www.ibtimes.com/]

4.   So...did u just start thinking of disabling JAVA?????

Apple Needs a Doctor : Bitten by JAVA - 1

1.   The year last ie 2012 was full of various security OS issue like it has always been over years...but one landmark news that made waves was the flashback malware that hit APPLE's Mac that has been long promoted as a safer OS amongst other peer competitors.But as always SIZE DOES MATTER..so as APPLE and market share grew, it became more proner. Dr  Web said that an estimated 600,000 Macs were as of April 2012 infected as a result of users unknowingly installing the FlashBack malware.So before I move ahead...here's a simple FAQ compiled to understand more about FLASHBACK :

What exactly is Flashback?

-  Flashback is a form of malware designed to grab passwords and other information from users 

-  Spread through Web browser and other applications such as Skype. 

-  The user typically mistakes it for a legitimate browser plug-in while visiting a malicious Web site. 

-  At this point, the software installs code designed to gather personal information and send it back to remote servers. 

Apple needs a DOCTOR

When did it first appear?

-  End of September 2011

-  Pretending to be an installer for Adobe's Flash the malware evolved to target the Java runtime on OS X, where users visiting malicious sites would then be prompted to install it on their machine in order to view Web content. 

What has Apple done about it?

-  Apple has its own malware scanner built into OS X called XProtect. 

-  Since Flashback's launch, the security tool has been updated twice.

-  A more recent version of the malware, however, got around XProtect by executing its files through Java. 

-  Apple closed off the malware's main entry point with a Java update on April 3, and has since released a removal tool as part of a subsequent Java update.

How do I tell if I have it?

-  Right now the easiest way to tell if your computer has been infected is to head to security firm F-Secure and download its Flashback detection and removal software. 

Malicious Shortened URLs : Rising Threat

1.     Internet today is all but a minefield of boogies,traps and malware.....every day so many threats are born....though most of them die but still a huge percent of them survive the security walls and become stronger by time as they are able to remain live and acvtive.In recent times shortened URLs have become popular amongst users (including me...:-) to conserve the typing space like in microblogging sites viz twitter etc.So typically a naive(???),prone user who submits his long URL to a site to get a shortened URL receives a second,specially coded shortened URL that redirects to the original URL.So here lies the weak hole that is most of the times exploitable by the attacker...because the actual destination URL is hidden in it....so going by the looks...there is nothing to worry...but it is the redirection that is a cause of worry...it may be right or may be redirecting to a malicious link....!!!!so when some one uses a free URL shortener ,he does not have control over that shortened link. And, should something happen to the provider of that URL shortener, then he risks redirecting ALL of shortened links elsewhere!!!

2.  We all know that clicking links is pretty tempting....so it is just a matter of one redirected malicious link click that makes the difference....so whats the solution????...actually companies like Facebook,Gmail, SBI, Paypal ,twitter etc are offering users the option of persistent SSL encryption and authentication across all the pages of their services including the login and all accessible pages.....but this does not stand good for all...for these sites also..it is optional to vide the settings for accessing....

India developing own Secure OS to strengthen Cyber Security

1.   India is developing own secure OS to strengthen cyber security.Got this news piece from here.The key points from the news are :

- India's own secure operating system to strengthen cyber security.

- 150 Engineers across the country have already been working on creating an Indian OS for over one year and a half. 

- According to Times of India ,it will be ready in next three years.

- There is no foreign involvement in this project. It is purely build by Indians.

2.   It is indeed heartening to know all this...but whats the point? Does the team of 150 engineers and the vision behind think they are creating a secure and 100% fool proof OS?...The moment it is released...there will be many vulnerabilities that will be gradually known...and then the same cat mouse race will being like with any other OS..so whats the point of starting from scratch?....will it not be wise to securify existing opensource available and invest in something like improving upon existing resources?.....Case in point,the DESI OS....will lag behind in terms of experiences gained by Windows and other OS Communities who have been in the game for years...........who have been improving daily for so many years!!!like Fedora...Ubuntu...they have been improving for last so many years to reach a level like as on date available to us....

3.  Although it is a veri good thought to have a desi OS....but I sincerely feel that we are slightly late in realizing the need of a desi OS...
