October 20, 2016Security issues on the internet can arise from many different sides. Though we often believe that viruses and other forms of malware are greatest threats that World Wide Web has to offer, situation is actually a lot more complicated than that. Our security is also challenged by the level of surveillance on the web, because practically our every step can be easily monitored, and in that monitoring helps everything – from your browser to your operating system. This is the reason why more and more people opt out for using alternative versions of operating systems, and so far Linux has proven to be at the very top. Fedora and Ubuntu are thus far the best offspring of Linux family, which is why security-conscious internet users often choose one of them as their OS. However, with alternative operating systems come compatibility issues that need to be considered, because you’ll face some difficulty when wanting to install different apps and plugins. Further more, if you strive to be as protected as possible on the web, then getting a VPN to match your alternative OS might be a good idea, because that way you’ll cover every aspect of your security. Seeing that compatibility problems stretch over VPN apps as well, here are some of them that will fit like a glove with your OS. Cyber Ghost We’ll start with a VPN that can grant you solid protection and which you can get without paying a dime. Cyber Ghost in its free edition can give you a good Open VPN protocol along which also comes unlimited bandwidth, which is pretty good for a free VPN. You will also get a kill switch, which will protect you from losing your privacy if you lose your VPN connection. One of the best things about Cyber Ghost...

June 21, 2015Mark Shuttleworth has lost his long-running fight to reverse a US$20m (£12.8m) bank charge levied after he transferred a fortune out of South Africa. In 2001, Shuttleworth, the founder of Ubuntu Linux maker Canonical, emigrated from his home nation of South Africa to the Isle of Man. In 2008, he tried to withdraw R2.5bn (US$204m, £128m) from his account in the South African Reserve Bank. The bank, under orders from the SA finance minister, withheld 10 per cent of the transfer as an exit charge. Shuttleworth was furious, and took the bank to a High Court in Pretoria to claim back his millions, basically calling the whole thing unconstitutional. The court said the exit charge was legit, but decided some of the currency exchange rules surrounding the fee were unlawful and unconstitutional. Shuttleworth took the matter higher to the Supreme Court of Appeal, which said the rules were valid, but the bank charge was not. The SA government and reserve bank also launched a cross-appeal. What a mess. The Linux entrepreneur’s case finally ended up before the South Africa Constitutional Court, which on Thursday this week ruled [PDF] that the South African Reserve Bank was right all along to withhold the wedge.

April 2, 2012From the boot menu or the boot disk select recovery mode, which is usually the second boot option. After you select recovery mode and wait for all the boot-up processes to finish, you’ll be presented with a few options. In this case, you want the Drop to root shell prompt option so press the Down arrow to get to that option, and then press Enter to select it. The root account is the ultimate administrator and can do anything to the Ubuntu installation (including erase it), so please be careful with what commands you enter in the root terminal. Once you’re at the root shell prompt, if you have forgotten your username as well, type ls /home That’s a lowercase L, by the way, not a capital i, in ls. You should then see a list of the users on your Ubuntu installation. In this case, I’m going to reset Susan Brownmiller’s password. To reset the password, type passwd username where usernameis the username you want to reset. In this case, I want to reset Susan’s password, so I type passwd susan You’ll then be prompted for a new password. When you type the password you will get no visual response acknowledging your typing. Your password is still being accepted. Just type the password and hit Enter when you’re done. You’ll be prompted to retype the password. Do so and hit Enter again. Now the password should be reset. Type exit to return to the recovery menu. After you get back to the recovery menu, select resume normal boot, and use Ubuntu as you normally would—only this time, you actually know the password!
