Link: Sysstat – All-in-One System Performance and Usage Activity Monitoring Tool For Linux

Sysstat is really a handy tool which comes with number of utilities to monitor system resources, their performance and usage activities. Number of utilities that we all use in our daily bases comes with sysstat package. It also provide the tool which can be scheduled using cron to collect all performance and activity data.

Link: How To Install Wine to Run Windows Software on Ubuntu

Wine is a free and open source application that aims to allow applications designed for Microsoft Windows to run on Unix-like operating systems. Wine also provides a software library, known as Winelib, against which developers can compile Windows applications to help port them to Unix-like systems.

Wine is a compatibility layer. It duplicates functions of Windows by providing alternative implementations of the DLLs that Windows programs call and a process to substitute for the Windows NT kernel. This method of duplication differs from other methods that might also be considered emulation, where Windows programs run in a virtual machine. In this article we are installing wine 1.7.25 version on Ubuntu 14.04.

Link: How to Encode H.265 Video Using ffmpeg on Linux

After H.264 came H.265. It also has a few other names, most commonly High Efficiency Video Coding (HEVC) or MPEG-H. H.265 doubles the data compression ratio compared to H.264 and can support resolutions up to 8192×4320. This means that video at the same quality needs only half of the bandwidth (or file size). Alternately, it means that the quality of the video can be substantially improved at the same bit rate, something very important for very high definition (i.e. 4K and 8K) displays.

Link: Review of the TBS MOI+ DVB S/S2 Satellite TV Linux Server – a bit like a HDHomeRun, but for Free-To-Air satellite signals

A couple of years ago, I acquired a HDHomeRun Dual device, and discovered how nice it was to be able to stream terrestrial TV signals to anywhere in my home via my local network. I set up a backend system so that I could record programs and enjoy watching them at my convenience. I wondered if it was also possible to do the same thing with the signals I received off my satellite dishes. So earlier this year I attempted to build a backend system that could receive free-to-air satellite signals and stream them to the various computers around my home, including the home theater PC’s that are connected to my HDTV receivers. Let’s just say that the first attempts didn’t work as well as I’d hoped. There is a huge learning curve, particularly if you’re not a programmer nor otherwise particularly geeky, and sometimes the hardware and the backend software just won’t cooperate.

Then I stumbled across a page on the TBS MOI+. I suspected that it might be able to accomplish what I’d been trying to do, and in a lot smaller package. So, I went online in an attempt to find some reviews on this device. To my surprise, little has been written about it, particularly in English. So, hoping to fill that gap, I contacted TBS and asked if they might be interested in providing a unit for review purposes. They graciously consented, and this review is the result. Just so you know, I did not promise to write only nice things about the unit, and I’m not getting paid anything for this review, beyond receiving the MOI+. So, this will be as honest of a review as I can make it.

Link: Encrypt DNS Traffic In Ubuntu With DNSCrypt [PPA]

DNSCrypt is a protocol for securing communications between a client and a DNS resolver, preventing spying, spoofing or man-in-the-middle attacks. To use it, you’ll need a tool called dnscrypt-proxy, which “can be used directly as your local resolver or as a DNS forwarder, authenticating requests using the DNSCrypt protocol and passing them to an upstream server“.

Link: How to reboot Linux automatically on Kernel Panic

A kernel panic is an action taken by an operating system upon detecting an internal fatal error from which it cannot safely recover. The term is largely specific to Unix and Unix-like systems; for Microsoft Windows operating systems the equivalent term is “stop error” (or, colloquially BSOD “Blue Screen of Death”).

…..

The default [is] to wait, so if this happen on one of your servers and you don’t notice it all its services could stay down for some time, while using an automatic reboot the problem could be solved quickly.

We can configure a directive that will automatically reboot the system when a kernel panic is detected.

Link: Setting Up DNS Server On CentOS 7

DNS, stands for Domain Name System, translates hostnames or URLs into IP addresses. For example, if we type www.unixmen.com in browser, the DNS server translates the domain name into its associated ip address. Since the IP addresses are hard to remember all time, DNS servers are used to translate the hostnames like www.unixmen.com to 173.xxx.xx.xxx. So it makes easy to remember the domain names instead of its IP address.

This detailed tutorial will help you to set up a local DNS server on your CentOS 7 system. However, the steps are applicable for setting up DNS server on RHEL and Scientific Linux 7 too.

Link: How to Use the Linux “find” Command to Locate Files

We have all lost files. You think a file is in a certain directory and yet when you go looking for it, you can’t find it. Most desktop-based Linux distributions have a way to find files from the desktop, but you can also find files from the command line using the find command.
