Apache HTTP Server is a free software/open source web server for Unix-like systems, Microsoft Windows, Novell NetWare and other platforms. Apache is notable for playing a key role in the initial growth of the World Wide Web,and continues to be the most popular web server in use, serving as the de facto reference platform against which other web serversare designed and judged.

Apache features configurable error messages, DBMS-based authentication databases, and content negotiation. It is also supported by several graphical user interfaces (GUIs) which permit easier, more intuitive configuration of the server.

sysrqd is a tiny daemon aiming to control sysrq over network.SysRq stands for System Request, and this are functions mapped to keyboard shortcuts by the kernel. You can use them by pressing Alt+SysRq+[key] (SysRq might be named “Print Screen” on your keyboard),Permits to execute usual SysRq commands by network, like: sync, umount, reboot, poweroff, sak, term, etc. where key can be s (sync), k (sak), 0 to 9 (logging level), b (reboot), etc.

The goal of this keyboard sequences is too be available even if you can’t do anything on your box, because you screwed up everything, or because it’s crashed or under very heavy load.

sysrqd can help you to use SysRq keys when you are not in front of your box,and you need to do Emergency Sync, R/O remount and reBoot.

In this howto we will learn how to build a Dynamic DNS Server. Normally when we configure DNS, we use static entries to resolve any FQDN. If we are using DHCP in our network which gives dynamic IPs to every computer that turns on or requests one, then it is not possible to configure DNS statically. For that we should configure our DNS with DHCP in a manner that whenever a computer gets a new IP, its FQDN will be automatically updated with the new IP in DNS.

Want to give your IT security or administrator staff access to Windows applications right in their preferred Linux desktop environment? Follow this tip and you can easily do this without needing to set up an expensive and complex Citrix environment. Also, did I mention that the following solution can be set up using free software?

Many network and security administrators want to use Linux as their operating system of choice due to the abundance of open source security tools available for Linux. But they still may need to run some Windows-only applications. So, their choices are to run a separate physical system or run Windows XP as a VM on VMware Virtual Server for Linux.

To install RPM files with Yast, simply type the following at the command line :

yast -i file.rpm

Afterwards you can easily remove these packages from within Yast.
If you downloaded source code from a program (tar.gz files) you can quickly make an RPM file from it to install it later on your or another pc (if dependencies are OK).

To do this...

  • System76 wants to build its own hardware for its Linux-based computers
    System76 is building up quite a name for itself, being one of a very limited number of companies selling only computers running Linux-based operating systems. Now the aim is to branch out; System76 wants to design and build its own hardware, while representing the open source community as it does so. At the moment, the hardware used in System76 systems is outsourced, but in the future this will change. The company says that it is moving into phase three of its development cycle, and this "moves product design and manufacturing in house." And you should set your expectations high: "We're about to build the Model S of computers. Something so brilliant and beautiful that reviewers will have to add an 11 to their scores."
  • AppCenter Spotlight: Beta Testers
    Over the past month we’ve been beta testing the new AppCenter with a number of developers, from elementary OS contributors to backers of our Indiegogo campaign. After testing out the submission process and getting some apps into the store (and seeing rapid updates!), I wanted to take a moment to highlight some of the first apps.
  • elementary OS to get improved AppCenter, showing off a few new applications
    I have to hand it to the elementary OS guys, they have a massive focus on design and it does look quite incredible. It is easily one of the best looking Linux distributions, which I do admire. Their new AppCenter, for example, looks extremely clean and clear.

Beijing Zoo is No Place for Pandas

Pandas in Beijing Zoo

I am a Panda lover. I work as a support engineer in an I.T company here in the United Kingdom. Most of my spare time is spent watching different Panda videos -- both old and new videos. Basically, it is my therapy; a 'stress release' for me. I find them to be adorable and precious creatures. As a matter of fact, I would like to volunteer to come to Sichuan. I want to experience and feel what it's like to be a Panda keeper, to be able to interact with them for real. The Panda is China's National Treasure, so it's a shame to watch the Panda videos from Beijing zoo, as the place is disgusting and not ideal for Pandas to live in (and for sure for all the rest of the animals who unfortunately got stuck in this prison cell).

The place looks like a ghost town. Lifeless and languished. Knowing that Pandas wear a thick fur on their body, can you imagine what it feels for them in 30C or 35C (summer temperature)? What it probably feels like all the time? Come on, if you really care, you must do something now, otherwise these Pandas will die. Please bring them back to their sanctuary where they really belong.

Linux 4.11 File-System Tests: EXT4, F2FS, XFS & Btrfs

With the Linux 4.11 kernel potentially being released as soon as today, here are some fresh benchmarks of Btrfs / EXT4 / F2FS / XFS on a solid-state drive and comparing the performance of 4.11 Git back to Linux 4.9 and 4.10. For those wondering if the block/file-system changes of Linux 4.11 have any impact on EXT4/F2FS/XFS/Btrfs for common I/O workloads or how these file-systems are comparing on this latest kernel, here are some benchmarks.
