Linux-Based Airtame 2 Offers an Enterprise Alternative to Chromecast

Sre, 10/10/2018 - 17:51

One category that often gets overlooked in the discussion of Linux computers is the market for HDMI dongle devices that plug into your TV to stream, mirror, or cast content from your laptop or mobile device. Yesterday, Google announced an extensively leaked third-gen version of its market-leading, Linux-powered Chromecast device. The latest Chromecast upgrades the WiFi radio to 5GHz and adds 2.4GHz Bluetooth while also overhauling the physical design.

Here, we look at a similar Linux-based HDMI dongle device that launched this morning with a somewhat different feature set and market focus. The Airtame 2 is the first hardware overhaul since the original Airtame generated $1.3 million on Indiegogo in 2013. The new version doubles the RAM, improves the Debian Linux firmware, and advances to dual-band 802.11a/b/g/n/ac, which is now known as WiFi 5 in the new Wi-Fi Alliance naming scheme that accompanied its recent WiFi 6 (ax) announcement.

New Manjaro Beta Builds a Better Arch

Sre, 10/10/2018 - 17:47

Regardless of which desktop you select, the welcome screen introduces Manjaro tools and get-acquainted details such as documentation, support tips, and links to the project site.

You can get a full experience in using the live session ISOs without making any changes to the computer's hard drive. That is another advantage to running Manjaro Linux over a true Arch distro. Arch distros usually do not provide live session environments. Most that do lack any automatic installation launcher from within the live session.

Caution: When you attempt to run the boot menu from the Manjaro DVD, pay attention to the startup menu. It is a bit confusing. To start the live session, go halfway down the list of loading choices to select the Boot Manjaro option. The other menu options let you configure non-default choices for keyboard, language, etc.

After the live medium loads the Manjaro live session, browse the categories in the welcome window. You can click the Launch Installer button in the welcome window or launch it after experiencing the live session by clicking on the desktop install icon or running the installation program from the main menu.

Installation is a simple and straightforward process. The Calamares installer allows newcomers to easily set up the distro. It gives advanced users lots of customization options.

Linux-driven LoRaWAN gateway ships with new “Wzzard” LoRa nodes

Sre, 10/10/2018 - 17:45

Advantech has launched a rugged, Arm Linux based “WISE-6610” LoRaWAN gateway in 100- or 500-node versions with either 915MHz or 868MHz support. There’s also a “Wzzard LRPv2 Node” that can connect four sensors at once.

Advantech announced the industrial WISE-6610 gateway and Wzzard LRPv2 Node for long-range, low-bandwidth LoRaWAN gateways on May 31, and judging from this Oct. 5 Electronics Weekly post, they are now available. Designed for I/O sensor data management and network protocol conversion primarily on private LoRaWAN networks, the products are part of a Wzzard LoRa Sensing Network family that includes a recent SmartSwarm 243 gateway that appears to be almost identical to the WISE-6610 (see farther below).

An introduction to using tcpdump at the Linux command line

Sre, 10/10/2018 - 10:15

Tcpdump is a command line utility that allows you to capture and analyze network traffic going through your system. It is often used to help troubleshoot network issues, as well as a security tool.

A powerful and versatile tool that includes many options and filters, tcpdump can be used in a variety of cases. Since it's a command line tool, it is ideal to run in remote servers or devices for which a GUI is not available, to collect data that can be analyzed later. It can also be launched in the background or as a scheduled job using tools like cron.

In this article, we'll look at some of tcpdump's most common features.

  • Fedora at LinuxDays 2018 in Prague

    LinuxDays, the biggest Linux event in the Czech Republic, took place at the Faculty of Information Technology of Czech Technical University in Prague. The number of registered attendees was a bit lower this year, it could be caused by municipality and senate elections happening on Fri and Sat, but the number got almost to the 1300 mark anyway.

    Besides a busy schedule of talks and workshops the conference also has a pretty large booth area and as every year I organized the Fedora one. I drove by car to Prague with Carlos Soriano and Felipe Borges from the Red Hat desktop team on Saturday morning and we were joined by František Zatloukal (Fedora QA) at the booth.

Games: XCOM 2, Humble Discovery Pack, Obsidian, Unreal Engine

  • XCOM 2: War of the Chosen - Tactical Legacy Pack DLC Out Now for Linux and macOS

    As promised, UK-based video games publisher Feral Interactive released today the Linux and macOS port of the XCOM 2: War of the Chosen - Tactical Legacy Pack DLC on Steam.

    The XCOM 2: War of the Chosen - Tactical Legacy Pack is a massive downloadable content (DLC) for the XCOM 2: War of the Chosen expansion pack for the XCOM 2 turn-based tactics video game. It brings two new gameplay modes, Legacy Ops and Skirmish Mode, as well as an Offline Challenge Mode.

  • XCOM 2: War of the Chosen - Tactical Legacy Pack out now and with Linux support right away

    It seems Feral had a bit of a surprise in store for us, as XCOM 2: War of the Chosen - Tactical Legacy Pack has released today and the Linux version is out.

    When it was announced, Feral Interactive said it would be available "shortly after the Windows release" and they certainly weren't kidding as it only released for Windows today too! Seriously good stuff from Feral, this is the way it should be with no waiting around. Really pleased they were able to do this for Linux gamers!

  • The Humble Discovery Pack is out with three nice Linux native games

    Another week, another bundle of games for you! The Humble Discovery Pack is now live with three nice Linux native games.

  • According to Kotaku, Microsoft is close to buying Obsidian

    In what could be a blow to Linux gamers who are fans of Obsidian RPGs, Microsoft is apparently close to acquiring the studio.

    [...]

    Naturally, this will be a worry to Linux gamers since this could mean future Obsidian titles may not arrive on Linux like they have before. Obsidian has given Linux fans Pillars of Eternity, Pillars of Eternity II and Tyranny recently so it would be a huge shame not to have their next story-driven RPG land on Linux.

    Microsoft acquiring anyone always makes me feel quite uneasy, since they could end up requiring future games they publish to be exclusive to their own store therefore locking out Steam. At least if they stayed on Steam and didn't do a Linux version (for whatever reason) of their next set of games, we would have Steam Play's Proton so it wouldn't be such a major issue.

  • Sources: Microsoft Is Close To Buying Obsidian

    “We do not comment on rumors or speculation,” said a Microsoft spokesperson.

  • Unreal Engine 4.21 Preview Brings Some Linux Improvements

Debian GNU/Linux 9 "Stretch" Gets New Kernel Patch to Fix Two Security Flaws

Sre, 10/10/2018 - 01:19

Coming just a week after the latest major kernel security update for Debian GNU/Linux 9 "Stretch," the new Linux kernel security patch is here to address a flaw (CVE-2018-15471) discovered by Google Project Zero's Felix Wilhelm in the hash handling of Linux kernel's xen-netback module, which could result in information leaks, privilege escalation, as well as denial of service.

"Felix Wilhelm of Google Project Zero discovered a flaw in the hash handling of the xen-netback Linux kernel module. A malicious or buggy frontend may cause the (usually privileged) backend to make out of bounds memory accesses, potentially resulting in privilege escalation, denial of service, or information leaks," reads the security advisory published by Salvatore Bonaccorso.

NanoPi Neo4 SBC breaks RK3399 records for size and price

Sre, 10/10/2018 - 01:14

FriendlyElec has launched a $45, Rockchip RK3399 based “NanoPi Neo4” SBC with a 60 x 45mm footprint, WiFi/BT, GbE, USB 3.0, HDMI 2.0, MIPI-CSI, a 40-pin header, and -20 to 70℃ support — but only 1GB of RAM.

In August, FriendlyElec introduced the NanoPi M4, which was then the smallest, most affordable Rockchip RK3399 based SBC yet. The company has now eclipsed the Raspberry Pi style, 85 x 56mm NanoPi M4 on both counts, with a 60 x 45mm size and $45 promotional price ($50 standard). The similarly open-spec, Linux and Android-ready NanoPi Neo4, however, is not likely to beat the M4 on performance, as it ships with only 1GB of DDR3-1866 instead of 2GB or 4GB of LPDDR3.

Linus' Behavior and the Kernel Development Community

Tor, 10/09/2018 - 19:20

On September 16, 2018, Linus Torvalds released the 4.19-rc4 version of the kernel, and he also announced he was taking a break from Linux development in order to consider his own behavior and to come up with a better approach to kernel development. This was partly inspired by his realization that he wasn't looking forward to the Kernel Summit event, and he said that "it wasn't actually funny or a good sign that I was hoping to just skip the yearly kernel summit entirely."

Security: Trusting the delivery of Firefox Updates, Reproducible Builds Weekly Report and Security updates for Tuesday

Tor, 10/09/2018 - 18:34
  • Trusting the delivery of Firefox Updates

    Providing a web browser that you can depend on year after year is one of the core tenet of the Firefox security strategy. We put a lot of time and energy into making sure that the software you run has not been tampered with while being delivered to you.

    In an effort to increase trust in Firefox, we regularly partner with external firms to verify the security of our products. Earlier this year, we hired X41 D-SEC Gmbh to audit the mechanism by which Firefox ships updates, known internally as AUS for Application Update Service. Today, we are releasing their report.

    Four researchers spent a total of 27 days running a technical security review of both the backend service that manages updates (Balrog) and the client code that updates your browser. The scope of the audit included a cryptographic review of the update signing protocol, fuzzing of the client code, pentesting of the backend and manual code review of all components.

Tor, 10/09/2018 - 18:30

The private bpftrace repository has just been made public, which is big news for DTrace fans. Created by Alastair Robertson, bpftrace is an open source high-level tracing front-end that lets you analyze systems in custom ways. It's shaping up to be a DTrace version 2.0: more capable, and built from the ground up for the modern era of the eBPF virtual machine. eBPF (extended Berkeley Packet Filter) is in the Linux kernel and is the new hotness in systems engineering. It is being developed for BSD, too, where BPF originated.
