You Never Forget Your First Web Server

Filed under
Linux

It was nearly 10 years ago (mid 1996) that I first put my own web server on the Internet. At the time my nearly state of the art computer was a 486 DX2/66 with 16MB of RAM running Linux 2.0.0. (I still remember upgrading from 1.x.x.).

Stx 1.0rc3 - An update

Reviews
-s

Stx released a new release candidate a few days back and just in time for my dying harddrive. Fortunately I received a new bigger harddrive for Christmas. ...unfortunately, I hadn't copied all of my partitions/installs to it before it completely gave up the ghost last night. Another good thing tho, I already had stx-1.0-rc3.iso sitting on my gentoo desktop (that I did ghost over the first day of installing said new hardware). So, this morning I installed stx-1.0-rc3 and figured why waste the experience. Here's a little update since our last look.

Hunting for the perfect Linux Media Center

Filed under
Linux

Over at NewsForge, Jay Lyman does a good job of explaining why HP's Media Hub, a Linux media system, came to nothing. He also talks with some analysts and people in the business about why Linux media centers haven't appeared.

That's all well and good, but Lyman doesn't ask the question I want to know the answer to: why don't we have a good Linux Media Center PC program?

The Linux Year [part 2] - a look back at 2005

Filed under
Linux

So what have we learned this year? Well, if Linux ever came of age, it's this year. It's possibly more confusing than ever to choose between open source and proprietary than it has ever been, but this has been the result from a desperate PR campaign, from both sides, to mis-foot the other.

Security: Hacker Summer Camp, Nexus Repository, Ransomware, Web Server Security

  • Hacker Summer Camp 2019: CTFs for Fun & Profit

    Okay, I’m back from Summer Camp and have caught up (slightly) on life. I had the privilege of giving a talk at BSidesLV entitled “CTFs for Fun and Profit: Playing Games to Build Your Skills.” I wanted to post a quick link to my slides and talk about the IoT CTF I had the chance to play. I played in the IoT Village CTF at DEF CON, which was interesting because it uses real-world devices with real-world vulnerabilities instead of the typical made-up challenges in a CTF. On the other hand, I’m a little disappointed that it seems pretty similar (maybe even the same) year-to-year, not providing much variety or new learning experiences if you’ve played before.

  • Nexus Repository Now Supports APT

    Beginning with version 3.17, Nexus Repository Manager supports APT (Advanced Package Tool) repositories. APT is a set of tools used to search, install, and manage packages on Debian, Ubuntu, and similar Linux distributions. With this new release, you can now host your own local APT repos. Developers benefit from no longer having to rely on connecting externally to a public repository every time an often-used package is needed. In the case of Debian-based Docker containers, the ability to locally cache Debian packages from public repositories can save copious amounts of time when rebuilding your containers. This can do wonders especially for containers built frequently in a CI pipeline and for the more traditional use-case of provisioning virtual machines.

  • Ransomware attack has hit 20 government agencies in Texas [iophk: Windows TCO]

    This week the state of Texas has joined the list of targets. According to Texas’s Department of Information Resources (DIR), more than 20 local government entities have been impacted by a ‘coordinated ransomware attack.’ DIR states that “the Texas Military Department, and the Texas A&M University System’s Cyberresponse and Security Operations Center teams are deploying resources to the most critically impacted jurisdictions.”

    No disclosure has beeen made regarding how much of a payment is being requested, though given recent attacks on other states the amount is likely to be eye-watering. Also absent is any information on which ‘local government entities’ have been affected.

  • Web server security – Part 8: Basic log file analysis

    Tools like lnav (“The Log File Navigator”) allow quicker analysis of log files. Instead of manually searching for attack-like behavior, you can use SQL queries, load and combine multiple files at once, and switch between different views.

    However, keep in mind that not only tools but also underlying processes and organization are important. You must know where log files are stored, how they are created and how long information is available. This requires a basic security concept. Understand the structure of your log files, and use customization of logging rules if available.

Chromebooks Switching Over To The BFQ I/O Scheduler

On Chromebooks when moving to the latest Chrome OS that switches over to a Linux 4.19 based kernel, BFQ has become the default I/O scheduler. BFQ has been maturing nicely and as of late there's been an uptick in interest around this I/O scheduler with some also calling for it to be used by default in distributions. Google has decided BFQ is attractive enough to enable by default for Chromebooks to provide better responsiveness. Read more

Debian: Salsa, Promoting Debian LTS and Debian Patch Porting System

  • salsa.debian.org: Postmortem of failed Docker registry move

    The Salsa admin team provides the following report about the failed migration of the Docker container registry. The Docker container registry stores Docker images, which are for example used in the Salsa CI toolset. This migration would have moved all data off to Google Cloud Storage (GCS) and would have lowered the used file system space on Debian systems significantly. [...] On 2019-08-06 the migration process was started. The migration itself went fine, although it took a bit longer than anticipated. However, as not all parts of the migration had been properly tested, a test of the garbage collection triggered a bug in the software. On 2019-08-10 the Salsa admins started to see problems with garbage collection. The job running it timed out after one hour. Within this timeframe it not even managed to collect information about all used layers to see what it can cleanup. A source code analysis showed that this design flaw can't be fixed. On 2019-08-13 the change was rolled back to storing data on the file system.

  • Raphaël Hertzog: Promoting Debian LTS with stickers, flyers and a video

    With the agreement of the Debian LTS contributors funded by Freexian, earlier this year I decided to spend some Freexian money on marketing: we sponsored DebConf 19 as a bronze sponsor and we prepared some stickers and flyers to give out during the event. The stickers only promote the Debian LTS project with the semi-official logo we have been using and a link to the wiki page. You can see them on the back of a laptop in the picture below.

  • Jaskaran Singh: GSoC Final Report

    The Debian Patch Porting System aims to systematize and partially automate the security patch porting process. In this Google Summer of Code (2019), I wrote a webcrawler to extract security patches for a given security vulnerability identifier. This webcrawler or patch-finder serves as the first step of the Debian Patch Porting System. The Patch-finder should recognize numerous vulnerability identifiers. These identifiers can be security advisories (DSA, GLSA, RHSA), vulnerability identifiers (OVAL, CVE), etc. So far, it can identify CVE, DSA (Debian Security Advisory), GLSA (Gentoo Linux Security Advisory) and RHSA (Red Hat Security Advisory). Each vulnerability identifier has a list of entrypoint URLs associated with it. These URLs are used to initiate the patch finding.
