If you are a network admin who are involved in testing an intrusion detection system or network access control policy, you may often rely on offline analysis using collected packet dumps. When it comes to storing packet dumps, libpcap's packet dump format (pcap format) is the most widely used by many open-source packet sniffing and […]Continue reading...

In June 2013, we had the unfortunate luck of a basement flood, caused by a tripped electrical breaker connected to our sump pump. There are so many things that can go wrong with a sump pump. You always are on guard for power outages, blown breakers, sump pump failures, clogged pipes and all manner of issues that can arise, which ultimately can end with a flooded basement. I needed a way to alert me of issues when I was not at home. Audible alarms are fairly cheap and are great when you are physically in the house. They fail miserably when you are ten miles away at work. I had a Raspberry Pi that I had tinkered with periodically but for which I never had a real purpose. I decided to try to put the Pi to work as a dedicated sump pit monitoring device. Hopefully, the Pi could send me SMS alerts if a problem arose while I was away.

MYIR introduced a pair of Linux- and Android-ready COMs and baseboards featuring Atmel’s low-power, 536MHz SAMA5D3 SoC, with LCD, GbE, and dual CAN ports. MYIR’s MCC-SAMA5D3X-C and MYC-SAMA5D3X computer-on-modules both feature Atmel’s Cortex-A5 based SAMA5D3 system-on-chip, but are implemented on two different form factors, and with different mixes of I/O. The soon-to-ship 82 x 55mm MCC-SAMA5D3X-C plugs into a baseboard via pin-headers on its underside, while the currently-available 68 x 45mm MYC-SAMA5D3X uses edgecard fingers to slot into a 200-pin SODIMM connector. Both COMs are supported by ready-to-use development baseboards.

I have been working on the Apache http server for almost 20 years now. I've written 9 books about httpd, and spoken at more than fifty conferences. I'm a member of the Apache Software Foundation, where I serve as a board member and as Executive Vice President. I am responsible for putting on ApacheCon, both in North America and Europe, which is the official conference of the ASF. Each of these things, I do because someone encouraged me to do something that I knew, deep down, I was incapable of doing, and then cheered me on as I did it.

Merge window for first Linux kernel of 2015 shows some interesting new features on the way, including very limited support for Microsoft's Surface technology

The General Public License Version 2 (GPLv2) continues to be the most widely used and most important license for free and open source software. Black Duck Software estimates that 16 billion lines of code are licensed under GPLv2. Despite its importance, the GPLv2 has been the subject of very few court decisions, and virtually all of the most important terms of the GPLv2 have not been interpreted by courts.

The week's big stories for your reading pleasure. Enjoy!

Aaeon launched two Mini-ITX boards powered by Intel Bay Trail SoCs, and featuring up to three video ports, one or two GbE ports, PCIe expansion, and more. We missed Aaeon’s Atom E3800 based “EMB-BT1? Mini-ITX motherboard when it was announced earlier this year, so we are including it here as we cover two newly released Atom and Celeron based 6.7 x 6.7-inch Mini-ITX SBCs announced by Aaeon this week. The new “EMB-BT2? and somewhat lower-powered “EMB-BT4? will both ship later this month with Fedora Linux support at unstated prices. Applications are said to include panel PCs, slim PCs, kiosks, and PoS devices.

Mozilla is planning to add support for Certificate Transparency checks in Firefox in the near future, but the company says that the feature won’t be turned on by default at first. Certificate Transparency is a proposal from engineers at Google that would help resolve some of the issues with certificate authorities, fraudulent certificates and stolen certificates. The framework would provide a public log of every certificate that’s issued by compliant CAs and also would provide proof to users’ browsers when each certificate is presented. Google is planning to implement CT in Chrome, and now Mozilla officials say that the company will implement in Firefox, but the process will be a gradual one.

Adlink unveiled an “LEC-iMX6? SMARC COM built around Freescale’s i.MX6, with up to 2GB soldered DDR3L and 64GB eMMC, plus -40 to 85°C temperature support. The LEC-iMX6 is designed for portable — or just plain small — industrial automation, medical, testing and measurement, transportation, and digital signage applications. Like most embedded vendors this year, Adlink uses the IoT acronym, and here it actually seems to fit.

A few months ago I took the Introduction to Linux course offered through edX. It's an 18 chapter course with lots of reading, some videos, and a casual level of testing your knowledge. I wrote about the first six chapters and how the course works in, What happens when a non-coder tries to learn Linux. My main goal in taking the course was to get a better, high level understanding of Linux. I didn't have to install Linux but wanted to, so before I started chapter 7, I did. I wanted to test out some of the things I was learning, and 'learning is doing' to a large extent.

After a full day at the annual meeting of the Opensource.com Community Moderators, it was time for the the last item on the agenda which simply said "Special Guest: TBD." Jason Hibbets, project lead and community manager for Opensource.com, stood up and began explaining, "In case it wasn't going to happen, I didn't want to say who it was. Months ago I asked for any dates he'd be in town. I got two, and picked one. This was one day out of three weeks that Jim was in town."

Talking to developers and reading about open source I often get the feeling that the general notion is that open source is just about code and commits. Put another way, "If you don't make commits for a project you are not contributing to it." Or so they say. That notion is far from the truth in my eyes. Let me tell you why.

The BigTrak is one of the most iconic toys of the 80s, with a recognisable design and very cool keypad controller. In issue 5 of RasPi magazine you can learn how to bring yours screaming into the 21st Century by upgrading its insides with a Raspberry Pi and control via a wireless PS3 controller. Now you don’t have to follow it around to make course corrections!

If there’s one business that values secrecy it’s brewing beer. Most breweries hold their cards very close to their chests. They keep their recipes and techniques away from the prying eyes of competitors to retain a competitive advantage.

The vivid difference of opinion over Debian's future direction has ended with a new fork of the Linux distribution. The dispute centred on plans to replace the sysvinit init system management toolkit with systemd, a similar but less-Linux-specific set of tools.

With the holidays happening this past week I combined last week and this week's big stories into the LXWR for you. Enjoy!

KDE was one of about 50 exhibitors at the LISA (Large Installation System Administration) Conference November 12th and 13th in Seattle. The expo was part of the week-long conference for system administrators that has been held annually since 1986. Expo participants included big name tech companies and smaller niche organizations offering products and services to this audience of professional technical people. As we discovered, KDE is well known among this audience.

This document describes how to install and configure Nagios in Ubuntu 14.04 Server.  Nagios is a powerful monitoring system that enables organizations to identify and resolve IT infrastructure problems before they affect critical business processes.

You can interface a Raspberry Pi with Arduino components – now learn how to program them from the Pi and control robots like the Makeblock. Learning to code is one of the best things about owning a Raspberry Pi for a lot of people. Python and C are easy enough to start with on the Pi and you can get great results in a short time. When it comes to physical computing and making, though, not much beats using the Arduino IDE to control the open source controllers, servos and sensors associated with the system. Once set up, we can also use the Pi to program the Makeblock robot we reviewed in issue 142 of Linux User & Developer, using either the built-in commands or your own code.
