openSUSE project has announced the release of openSUSE 13.1 today!

 "Dear contributors, friends and fans: the release is here! Eight months of planning, packaging, adding features, fixing issues, testing and fixing more issues has brought you the best that free and open source has to offer, with our green touch: stable and awesome. This release did benefit from the improvements to our testing infrastructure and much attention to bug fixing. While a combination of over 6,000 packages supporting 5 architectures can never be perfect, we're proud to say this really does represent the best free software has to offer! The latest desktops (five of them!), server and cloud technologies, software development tools and everything in between are included."

OSv, the best OS for the cloud!

OSv reduces the memory and cpu overhead imposed by traditional OS. Scheduling is lightweight, the application and the kernel cooperate, memory pools are shared. It provides unparalleled short latencies and constant predictable performance, translated directly to capex  saving by reduction of the number of OS instances/sizes.
OSv runs on top of unmodified KVM, Xen and Amazon EC2 (HVM only, debug mode).
VMware support is planned later on this year. Public, private, enterprise virtualization and even developer's laptop, we'll support them all. Support for non x86 architectures is planned in the future.
 OSv is designed from the ground up to execute a single application on top of a hypervisor, resulting in superior performance and effortless management.
"“It's not a Linux kernel with a new userspace. It isn't a Linux distribution,” said Avi Kivity, a co-founder of Cloudius and former co-maintainer of KVM, the Linux kernel-based virtual machine. “It's a completely new kernel that we wrote from scratch and that's why it's so exciting.”
While it was built completely on Linux, OSv is not Linux. It is an operating system written in C++ and designed to optimize the performance of a single application in the cloud.
 (For more of the technical details, see The Register's coverage of OSv's September launch.)

Linux backdoor "Fokirtor" injects code into SSH traffic.

As this article from The Register shows a newly discovered backdoor is being exploited in the wild.
"The attackers understood the target environment was generally well-protected. In particular, the attackers needed a means to avoid suspicious network traffic or installed files, which may have triggered a security review. Demonstrating sophistication, the attackers devised their own stealthy Linux backdoor to camouflage itself within the Secure Shell (SSH) and other server processes.
This backdoor allowed an attacker to perform the usual functionality — such as executing remote commands — however, the backdoor did not open a network socket or attempt to connect to a command-and-control server (C&C). Rather, the backdoor code was injected into the SSH process to monitor network traffic and look for the following sequence of characters: colon, exclamation mark, semi-colon, period (“:!;.”).
After seeing this pattern, the back door would parse the rest of the traffic and then extract commands which had been encrypted with Blowfish and Base64 encoded."

Nagios: Industry Standard In IT Infrastructure Monitoring

Nagios is a powerful monitoring system that enables organizations to identify and resolve IT infrastructure problems before they affect critical business processes.

Designed with scalability and flexibility in mind, Nagios gives you the peace of mind that comes
 from knowing your organization's business processes won't be affected by unknown outages.
Nagios is a powerful tool that provides you with instant awareness of your organization's
mission-critical IT infrastructure. Nagios allows you to detect and repair problems and mitigate
 future issues before they affect end-users and customers.

What Nagios Provides

By using Nagios, you can:
  • Plan for infrastructure upgrades before outdated systems cause failures
  • Respond to issues at the first sign of a problem
  • Automatically fix problems when they are detected
  • Coordinate technical team responses
  • Ensure your organization's SLAs are being met
  • Ensure IT infrastructure outages have a minimal effect on your organization's bottom line
  • Monitor your entire infrastructure and business processes

How It Works


IT staff configure Nagios to monitor critical IT infrastructure components, including system metrics, network protocols, applications, services, servers, and network infrastructure.


Nagios sends alerts when critical infrastructure components fail and recover, providing administrators with notice of important events. Alerts can be delivered via email, SMS, or custom script.


IT staff can acknowledge alerts and begin resolving outages and investigating security alerts immediately. Alerts can be escalated to different groups if alerts are not acknowledged in a timely manner.


Reports provide a historical record of outages, events, notifications, and alert response for later review. Availability reports help ensure your SLAs are being met.


Scheduled downtime prevents alerts during scheduled maintenance and upgrade windows.

ZoneMinder is intended for use in single or multi-camera video security applications, including commercial or home CCTV, theft prevention and child, family member or home monitoring and other domestic care scenarios such as nanny cam installations. It supports capture, analysis, recording, and monitoring of video data coming from one or more video or network cameras attached to a Linux system. ZoneMinder also support web and semi-automatic control of Pan/Tilt/Zoom cameras using a variety of protocols. It is suitable for use as a DIY home video security system and for commercial or professional video security and surveillance. It can also be integrated into a home automation system via X.10 or other protocols.

ZoneMinder is an integrated set of applications which provide a complete surveillance solution allowing capture, analysis, recording and monitoring of any CCTV or security cameras attached to a Linux based machine. It is designed to run on distributions which support the Video For Linux (V4L) interface and has been tested with video cameras attached to BTTV cards, various USB cameras and also supports most IP network cameras. A partial list is given in the Wiki and Support sections, please give feedback in the Forums if it works with yours. ZoneMinder also requires MySQL and PHP, and is enhanced by a webserver such as Apache.
ZoneMinder is highly componentised and comprises both the back-end daemons which do the actual image capture and analysis and a user friendly web GUI enabling you to both monitor the current situation and view and organise historical events that have taken place. The web GUI allows you to check and control your ZoneMinder installation from other computers in your home or from anywhere in the world. ZoneMinder does not require X at all, or the web interface for day-to-day functions and so is also suitable for 'headless' systems. There is also a simple xHTML interface allowing basic monitoring from suitable phones! Recent versions of ZoneMinder also include optional DVR (digital video recorder) functions allowing you to pause, rewind and even digitally zoom both live and historical video.
There is no hard upper or lower limit to the number of cameras that ZoneMinder can support, it entirely depends on the resources available on the host PC. This means that a basic home CCTV system can often be installed on old hardware that may be lying around unused giving you DIY CCTV completely for free!
Take a look at the feature list and screenshots to see a bit more detail on what it does and then please feel free to download it and have a play. If you have any problems then please have a look through the Support and FAQ pages and the Forums and see if they help solve your problem. If you're after compatible hardware then I sometimes have special deals on the Shop page.
