TW My sysadmin toolbox

Filed under
Software

I maintain a Web server using Apache 2, PHP, Perl, MySQL, and OpenSSL; an IMAP server running the up-and-coming RoundCube Webmail client; and a server for streaming MP3s. GNU Emacs, OpenSSH, TightVNC, and netstat are just a few of the tools I use to maintain my servers.

Sealing Red Hat security gaps with open source security tools

Filed under
Software

Maybe you think open source doesn't have the chops for security. Sure, you're using Apache, Tomcat, MySQL and other open source applications in mission critical situations. You're using open source network management tools, like Nagios or OpenNMS, the latter of which is a complete enterprise network management solution. None of this worries you, but you don't feel comfortable using open source tools for IT security.

OpenVZ Delivers Easy Virtualization

Filed under
Software

Understanding virtualization is not an easy thing to do. The concept of many virtual machines running on board a single physical machine sounds all well and good but to many, even in the IT field, the idea seems rather, well... virtual.

Linux Audio Comparison

Filed under
Software

Of the challenges that GNU/Linux users face when choosing hardware components for any system is the sound card compatibility. ALSA, or officially known as Advanced Linux Sound Architecture, provides much of the audio and MIDI functionality to Linux users and is largely replacing OSS (Open Sound System). Today we are examining Linux audio performance in the gaming environment with a slew of various sound cards by examining their effect on frame-rate performance.

Openwashing Leftovers

The Last Independent Mobile OS

The year was 2010 and the future of mobile computing was looking bright. The iPhone was barely three years old, Google’s Android had yet to swallow the smartphone market whole, and half a dozen alternative mobile operating systems—many of which were devoutly open source—were preparing for launch. Eight years on, you probably haven’t even heard of most of these alternative mobile operating systems, much less use them. Today, Android and iOS dominate the global smartphone market and account for 99.9 percent of mobile operating systems. Even Microsoft and Blackberry, longtime players in the mobile space with massive revenue streams, have all but left the space. Then there’s Jolla, the small Finnish tech company behind Sailfish OS, which it bills as the “last independent alternative mobile operating system.” Jolla has had to walk itself back from the edge of destruction several times over the course of its seven year existence, and each time it has emerged battered, but more determined than ever to carve out a spot in the world for a truly independent, open source mobile operating system. After years of failed product launches, lackluster user growth, and supply chain fiascoes, it’s only been in the last few months that things finally seem to be turning to Jolla’s favor. Over the past two years the company has rode the wave of anti-Google sentiment outside the US and inked deals with large foreign companies that want to turn Sailfish into a household name. Despite the recent success, Jolla is far from being a major player in the mobile market. And yet it also still exists, which is more than can be said of every other would-be alternative mobile OS company. Read more

How I Quit Apple, Microsoft, Google, Facebook, and Amazon

It was just before closing time at a Verizon store in Bushwick, New York last May when I burst through the door, sweaty and exasperated. I had just sprinted—okay I walked, but briskly—from another Verizon outlet a few blocks away in the hopes I’d make it before they closed shop for the night. I was looking for a SIM card that would fit a refurbished 2012 Samsung Galaxy S3 that I had recently purchased on eBay, but the previous three Verizon stores I visited didn’t have any chips that would fit such an old model. When I explained my predicament to the salesperson, he laughed in my face. “You want to switch from you current phone to an... S3?” he asked incredulously. I explained my situation. I was about to embark on a month without intentionally using any services or products produced by the so-called “Big Five” tech companies: Amazon, Apple, Facebook, Google, and Microsoft. At that point I had found adequate, open source replacements for most of the services offered by these companies, but ditching the Android OS, which is developed by Google, was proving difficult. Most of the tech I use on a day-to-day basis is pretty utilitarian. At the time I was using a cheap ASUS laptop at work and a homebrew PC at my apartment. My phone was a Verizon-specific version of the Samsung Galaxy J3, a 2016 model that cost a little over $100 new. They weren't fancy, but they’ve reliably met most of my needs for years. For the past week and a half I had spent most of my evenings trying to port an independent mobile OS called Sailfish onto my phone without any luck. As it turned out, Verizon had locked the bootloader on my phone model, which is so obscure that no one in the vibrant Android hacking community had dedicated much time to figuring out a workaround. If I wanted to use Sailfish, I was going to have to get a different phone. Read more

RISC-V Will Stop Hackers Dead From Getting Into Your Computer

The greatest hardware hacks of all time were simply the result of finding software keys in memory. The AACS encryption debacle — the 09 F9 key that allowed us to decrypt HD DVDs — was the result of encryption keys just sitting in main memory, where it could be read by any other program. DeCSS, the hack that gave us all access to DVDs was again the result of encryption keys sitting out in the open. Because encryption doesn’t work if your keys are just sitting out in the open, system designers have come up with ingenious solutions to prevent evil hackers form accessing these keys. One of the best solutions is the hardware enclave, a tiny bit of silicon that protects keys and other bits of information. Apple has an entire line of chips, Intel has hardware extensions, and all of these are black box solutions. They do work, but we have no idea if there are any vulnerabilities. If you can’t study it, it’s just an article of faith that these hardware enclaves will keep working. Now, there might be another option. RISC-V researchers are busy creating an Open Source hardware enclave. This is an Open Source project to build secure hardware enclaves to store cryptographic keys and other secret information, and they’re doing it in a way that can be accessed and studied. Trust but verify, yes, and that’s why this is the most innovative hardware development in the last decade. Read more
