Fedora 26 Beta Comes with New Features » Linux Magazine

The Fedora project has announced the beta of Fedora 26, the latest version of Fedora OS. Three editions of Fedora target three different markets: Fedora 26 Workstation Beta, Fedora 26 Server, and Fedora 26 Atomic.

As the name implies, Workstation targets desktop users, the Server edition is aimed at sys admins running servers, and Atomic targets DevOps, for managing cloud- and container-centric infrastructures.

Although each edition targets a different market segment, they all share the same fundamental Fedora technologies, and the only differences are in what comes packaged with each edition.

All three versions share these new components: updated compilers and languages, including GNU Compiler Collection (GCC) 7; Go 1.8; Python 3.6 and Ruby 2.4; DNF 2.0 with backward compatibility with Yum; a new storage configuration screen for the Anaconda installation program, enabling “bottom-up” configuration from devices and partitions; and updates to Fedora Media Writer that enable users to create bootable SD cards with Fedora for ARM-based devices, like Raspberry Pi.

New in the desktop edition is Gnome 3.24, which offers many new features, including batch rename of files and night mode. One of the highlights of this release is many improvements to Builder – to support a number of application build systems, including Flatpak, CMake, Meson, and Rust – in addition to integration with Valgrind for project profiling.

As containers become more and more important, Fedora Atomic offers a great platform for running container-based workloads in the cloud or on bare metal. One of the most notable features of Fedora Atomic Host is containerized Kubernetes to run different versions of the container orchestration engine.

All three editions are available for download and testing.

Trojan Turns Raspberry Pi into a Cryptocurrency… » Linux Magazine

The Russian security firm Doctor Web has discovered two trojan programs that target Linux machines. One Trojan turns Raspberry Pi machines into a cryptocurrency mining device, and the other runs a proxy server on Linux systems.

The Trojan named Linux.MulDrop.14 targets Raspberry Pi devices, changing the password on the devices it infects, then unpacking and launching a miner, which, in an infinite loop, starts searching for network nodes with an open port 22 to replicate itself.

According to Doctor Web, “The Trojan is a script that contains a compressed and encrypted application designed to mine cryptocurrency.”

The second Trojan, dubbed Linux.ProxyM, uses a special range of methods to detect honeypots – special decoy servers used by digital security specialists to examine malicious software.

“Once launched, it connects to its command and control server and, after getting confirmation from it, runs a SOCKS proxy server on the infected device. Cybercriminals can use this Trojan to ensure that they remain anonymous online,” noted Doctor Web.

Software-Defined Storage Products: IT Pros Offer Insight

Find out what users have to say about products in the emerging SDS market.

Software-defined storage promises two very attractive benefits to the enterprise: flexibility and lower cost. But how can IT pros know which software-defined storage (SDS) product will best meet the needs of their business?

Peer reviews published by real users can facilitate their decision-making with user feedback, insight, and product rankings that collectively indicate which products are in the lead.

Based on our real user reviews at IT Central Station, these products are some of the top choices for software-defined storage today.


A senior system engineer said, “The support we get from Nutanix is easily the best from all vendors we work with. If you open a case you directly speak to an engineer which can help quickly and efficiently. Our customers sometimes open support cases directly (not through us) and so far the feedback was great.”

However, a CTO at an IT consulting firm said while Nutanix has the ability to connect to Azure or AWS for storing backups, he would like to have the capability to spin up a backup on Azure or AWS for disaster-recovery purposes.

“Right now, you can only send a backup to either Azure or AWS. We would like to take a backup and spin it up to an actual server that could be connected to by users from the outside,” he added.

Here are more Nutanix reviews by IT Central Station users.

VMware vSAN

A senior systems administrator and storage specialist in the government sector said he finds that vSAN allows for very easy administration. “The fact that you don’t have LUNs to set up and assign is great. The ability to set up storage policies and assign them at the disk level is also a great part of this product,” he said. “You can allow for different setups for different workload requirements.”

A senior manager of IT infrastructure noted that “The vSAN Hardware Compatibility List Checker needs to improve, since currently it is a sore point for vSAN. You need to thoroughly check and re-check the HCL with multiple vendors like VMware, in the first instance, and manufacturers like Dell, IBM, HPE, etc., as the compatibility list is very narrow. I would definitely be happy if there is significant additional support for more models of servers from Dell, IBM, HPE, etc.”

HPE StoreVirtual

A network engineer at a tech service firm reported that “Shelf level-redundancy is one of the big things that StoreVirtual has had before some other SAN manufacturer or SAN model brands, which is pretty nice. It can be rather expensive because you are much less efficient when you have that redundancy, but it’s definitely a benefit if you really need access to that data.

But a solutions engineer at an insurance company said the product’s user interface needs to be updated. “It’s getting kind of long in the tooth, and the user interface makes it look a lot more complex than it actually is to manage, and I think that you can mask a lot of that with a refresh of the user interface. While HPE has created a new HTML5 UI for the HyperConverged 380, it is not available to the rest of the StoreVirtual population.”

Dell EMC ScaleIO

An engineer at a tech vendor that is both a customer and partner with Dell EMC likes the ScaleIO user interface. “EMC has been working with storage for a long time. Therefore, they know how to clearly present any important data, including data flow and each drive’s IOPS/bandwidth; and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects. It controls them, as well as maintaining them well.”

He added that “If they could introduce a write cache feature, the product would be perfect overall.”
