Knowing how to create and manage KVM virtual machines from command line can be really useful in certain scenarios: when working on headless servers, for example. Nonetheless, being able to script interactions with virtual machines can greatly improve our productivity. In this tutorial you will learn how to create, delete, clone and manage KVM machines with the help of few utilities.

HiDPI monitors are becoming more popular than ever. Learn how to tailor your Linux desktop to look good with these high-resolution screens.

In this week's Top 5, we highlight brewing beer, home automation basics, software standards, Node-RED on a Raspberry Pi, and LinchPin for the cloud.

Antonio Larrosa is the current president of KDE España and he and I have been friends for quite some time now. It may seem logical, since we both live in Málaga, are passionate about Free Software in general, and KDE in particular. But in most other respects we are total opposites: Antonio is quiet, tactful, unassuming and precise. Enough said.

Co-routines have been the biggest addition in Kotlin 1.1. They are absolutely great because of their power, and the community is still discovering how to make the most of them. Simply stated, co-routines are a way of writing asynchronous code sequentially. Instead of filling it all up with callbacks, you can write your lines of code one after the other. Some of them will have the ability to suspend execution and wait until the result is available.

As the CIA’s Linux-targeting OutlawCountry and Gyrfalcon code is revealed, two reports claim Linux malware attacks are rising quickly. Over the past few years, anecdotal evidence has suggested that security threats to Linux devices are on the rise. Last fall’s Mirai botnet attacks, which turned thousands of Linux devices into a zombie army used to […]

Depending upon the event you use to start the clock, cloud computing is only a little more than 10 years old. Some terms and concepts around cloud computing that we take for granted today are newer still. The National Institute of Standards and Technology (NIST) document that defined now-familiar cloud terminology—such as Infrastructure-as-a-Service (IaaS)—was only published in 2011, although it widely circulated in draft form for a while before that.

Over the past few years, anecdotal evidence has suggested that security threats to Linux devices are on the rise. Last fall’s Mirai botnet attacks, which turned thousands of Linux devices into a zombie army used to attack infrastructure via Distributed Denial of Service (DDoS), were particularly effective in waking up the Linux community.

This article is based on OpenFlow and OVSDB connection between SDN controller and OpenFlow-based switches and provides details on connection lifecycle. We will use open source SDN controller i.e. Opendaylight (ODL) Carbon release and OpenFlow virtual switch i.e. OpenVswitch (OVS) version 2.6.0 to describe OVSDB and Openflow connection.

Mozilla unveiled “Project Things,” which builds upon standard web technologies and the Web of Things project, and released code that runs on a Raspberry Pi. In March of last year, a few months after Mozilla announced it was shutting down its Firefox OS project for Linux-based mobile phones, it unveiled four Firefox OS based “Connected […]

Whether you're writing about your open source project or your open source adventures, work, and exploration, if you're investing time and energy into creating a blog, you want to get as many eyeballs as possible seeing that content. read more

As part of SSH security, We can easily configure Idle or Inactive SSH Sessions disconnection after Few Minutes Of Inactivity.

Security boffins have discovered a critical vulnerability in a GnuPG cryptographic library that allowed the researchers to completely break RSA-1024 and successfully extract the secret RSA key to decrypt data. Gnu Privacy Guard (GnuPG or GPG) is popular open source encryption software used by many operating systems from Linux and FreeBSD to Windows and macOS X. It's the same software used by the former NSA contractor and whistleblower Edward Snowden to keep his communication secure from law enforcement. The vulnerability, labeled CVE-2017-7526, resides in the Libgcrypt cryptographic library used by GnuPG, which is prone to local FLUSH+RELOAD side-channel attack.

WikiLeaks yesterday released documentation on two very specific scripts meant to steal OpenSSH login credentials from the client side. One script is for Windows clients, the other for Linux clients.
