In this article we will look on how to automatically chroot jail selected user ssh login based on the user group. This technique can be quite useful if you what your user to be provided with a limited system environment and at the same time keep them separate from your main system. You can also use this technique to create a simple ssh honeypot. In this tutorial you will learn how to create a basic chroot environment and how to configure your main system's sshd to automatically chroot jail selected users upon the ssh login.
Developers at Google and Mozilla have demonstrated interoperability between their implementations of WebRTC, allowing them to make video calls without plug-ins. WebRTC is being developed within the W3C and IETF communities as a future standard for HTML5-capable browsers to allow them to create HD video quality connections, between servers and browsers or between browser peers, without resorting to third-party or non-standard plugins. Two different web browsers being able to communicate using WebRTC is a significant milestone in that standard's development. Using the current Chrome 25 Beta and a recent Firefox Nightly, Todd Simpson, Mozilla's Chief Innovation Officer and Hugh Finnan, Google's Director of Product Management were able to video chat from their respective browsers.
On the Linux Planet, few issues have been more contentious in recent years than Microsoft's Secure Boot and Oracle's acquisition of Sun Microsystems. Both issues surfaced again this past week.
Software developers are racing to patch a recently discovered vulnerability that allows attackers to recover the plaintext of authentication cookies and other encrypted data as they travel over the Internet and other unsecured networks.The discovery is significant because in many cases it makes it possible for attackers to completely subvert the protection provided by the secure sockets layer and transport layer protocols. Together, SSL, TLS, and a close TLS relative known as Datagram Transport Layer Security are the sole cryptographic means for websites to prove their authenticity and to encrypt data as it travels between end users and Web servers. The so-called "Lucky Thirteen" attacks devised by computer scientists to exploit the weaknesses work against virtually all open-source TLS implementations, and possibly implementations supported by Apple, Microsoft, and Cisco Systems as well.
Dell’s (NASDAQ: DELL) board of directors will reportedly meet this evening (Monday, Feb. 4) to vote on a leverage buyout that may take the company private, Bloomberg reported. Indeed, Silver Lake Management, Microsoft (NASDAQ: MSFT) and Michael Dell are expected to to be among Dell’s key investors. Among the potential concerns for channel partners: Will Microsoft’s potential stake in Dell allow the software giant to dictate the types of software Dell offers to mobile, desktop, server and cloud partners?
Wait a minutes, did I just write that the patch addressed 50 security holes? I’ve got a five pound block of Swiss cheese in the fridge that has fewer holes than that. I think if I was Larry Ellison I would be ashamed to admit I’d allowed that many security vulnerabilities to accrue unfixed while any project was under my care. I think I’d fix ten a day or something in five separate patches and try to make it look like I had my security eagles working overtime finding new holes ahead of the bad guys.
Over the past few months there's been several Phoronix articles about Wine-Mono, a fork of Mono and a Win32 build of this open-source Microsoft .NET implementation for Wine. Wine-Mono can be used in place of Microsoft's official .NET framework when it's needed as a dependency for Windows programs running within Wine. Unfortunately, Wine-Mono doesn't always work out well...
Like Acer's C7, HP's Chromebook is a lightly modified version of one of its low-end Windows laptops, the HP Pavilion Sleekbook 14-b010us. That laptop includes a Windows license and several upgraded components, but the body and build quality of both should be more or less identical. Despite this similarity, don't expect to be able to buy the Chromebook version and put your own Windows license on it—while a version of Ubuntu has been made that is compatible with Chromebooks' locked-down bootloaders, installing alternate operating systems on the computers is a non-trivial undertaking.
The polls are closed and the [url=http://www.linuxquestions.org/questions/linux-news-59/2012-linuxquestions-org-members-choice-award-winners-4175448592/]results for the 2012 LinuxQuestions.org Members Choice Awards[/url] are in. Debian, Android, Raspberry Pi and LibreOffice are among the winners. The Members Choice Awards allow members of the Linux community to choose their favorite products in a variety of categories including Mobile Distribution of the Year, Server Distribution of the Year, Database of the Year, NoSQL Database of the Year and Desktop Environment of the Year. The total number of categories this year was 30.
It was in September of 2010 that the formation of the Document Foundation was announced. It's now two and a half years later, and with the release of LibreOffice 4.0, its not only flourishing, but forging a path independent of its predecessor.
Munich's City Council has criticised the HP study, commissioned by Microsoft, that claims to have identified high costs for Munich's Linux migration. There is no reason to adjust its own, significantly lower figures, said the Council
It's clear iOS and Android rule the roost among developers today, but there are number of promising alternatives on the way or already here including a maturing HTML5 standard and several open source offerings. I run down the options with Telerik's Todd Anglin.
