Device not managed error actually is an interesting error. When I tested, Device not managed error only happened to Wired Network interfaces (such as eth0 or eth1) in both Debian and Kali Linux. It doesn’t seem to happen to wireless network interfaces. When a user connects their Laptop or Computer to a LAN cable, suddenly they get this Wired Network interface “Device not managed error” and they can’t browse internet.

Most people end up searching for “Firefox can’t connect to Internet” or “Unable to browse internet in Kali Linux” or such. Those search strings will take to nowhere. This guide takes you through step by step procedures on fixing “Wired Network interface Device not managed error” in Debian and Kali Linux.

Have you made the switch to Windows 10 on your primary operating system? With it being free, and Microsoft pushing the update to users, most of you probably already have. And if you haven’t, listen. XP is dead. Let it go. ♫ LET IT GO! LET TO GO-OH-OH! ♫ Sorry, where was I? Oh, yeah, Windows 10 is awesome.

Side note : Even if you’re a Tomb Raider fan, you probably shouldn’t buy it from the Windows Store as your lock screen would suggest.    To remove Windows 10’s lock screen ads, click on your Start menu, and open up the Settings app: From here, choose the Personalization setting, and then navigate to the Lock Screen tab. Once this is open, find the field that reads “Windows Spotlight”, and click on the box. You can switch this to display either a “Picture” or a “Slideshow”, depending on your personal preference. This will disable Microsoft from automatically pushing ads to your login screen without your permission. Lastly, once you’ve selected the new s

Owing to the tremendous cyber-attacks on some of the most significant government websites in the past, the government of India has now launched its own operating system called Bharat Operating System Solution or BOSS , to protect confidential information from hackers. In fact, enhancing cyber-security has to come in the first place on the political agenda of all the governments across the world, considering the fact that “ obtaining government information ” always remains the first target of anti-social elements, Naxalites and terrorists. That means increased cyber-security can play a substantial role in enhancing a nation’s national security. The Indian Government’s initiative to implement its own operating system BOSS as a significant step towards protecting cyber-security is expected to be an eye opener for other countries, which are constantly facing cyber-attacks from hackers. Boss, which is developed by the Centre of Development of Advanced Computin
