Linux on the Corporate Desktop: Success with Kanotix

Filed under
Linux

About 2 years ago we went live with our first Linux Desktop in the production environment. The format we settled on was a LiveCD for ease of updates, administration and resilience. They were initially used to replace the dumb telnet terminals a lot of our staff were using for data entry, in order to give them the extra functionality (web browsing, office suite etc) of a Windows PC without the extra administration/maintenance overheads.

A LINUX User Looks at XANDROS Desktop 4

Linux
Reviews

I have written about XANDROS several times during the past couple of years and always felt that the distribution was something special. XANDROS has never tried to have the latest and greatest, just the most recent stable programs. It is also a commercial distribution meaning the basic edition of Desktop 4 will run about $40 USD and the premium about $80 USD.

This is the "Official Guide", but definitely isn't the dry tome you might expect if, for example RedHat had written it. This flows well, is chatty and light, doesn't talk down to you, and is full of tips and suggestions.

Despite all the discussions you might have read, SSH is a secure way to remotely connect to a GNU/Linux host. Unless you connect via SSH passwordlessly, using a public/private key pair, there is however a risk SSH is not really protecting you from: brute force attacks.

The developmental release of SUSE Linux 10.2 alpha 2 hit mirrors a day ahead of schedule and with the announcement came some big news. The openSUSE project of SUSE Linux will soon become known as openSUSE, starting with alpha 3, to avoid confusion with the enterprise level products. It was reported that the new naming should be visible by beta 1. This was the biggest news associated this release. Other than one other small surprise, there isn't much difference between alpha1 and alpha2.

  • What salary can a sysadmin expect to earn?

    The path to reliable salary data sometimes is sometimes paved with frustration. That’s because the honest answer to a reasonable question—what should I be paid for this job?—is usually: "It depends." Location, experience, skill set, industry, and other factors all impact someone’s actual compensation. For example, there’s rarely a single, agreed-upon salary for a particular job title or role. All of the above applies to system administrators. It’s a common, long-established IT job that spans many industries, company sizes, and other variables. While sysadmins may share some common fundamentals, it’s certainly not a one-size-fits-all position, and it’s all the truer as some sysadmin roles evolve to take on cloud, DevOps, and other responsibilities. What salary can you expect to earn as a sysadmin? Yeah, it depends. However, that doesn’t mean you can’t get a clear picture of what sysadmin compensation looks like, including specific numbers. This is information worth having handy if you’re a sysadmin on the job market or seeking a promotion. Let’s start with some good news from a compensation standpoint. Sysadmins—like other IT pros these days—are in demand. "In today’s business environment, companies are innovating and moving faster than ever before, and they need systems that can keep up with the pace of their projects and communications, as well as help everything run smoothly," says Robert Sutton, district president for the recruiting firm Robert Half Technology. "That’s why systems administrators are among the IT professionals who can expect to see a growing salary over the next year or so."

  • Run Mixed IT Efficiently, The Adient – SUSE Way.

  • Package Management Domain Model

    When I wrote this model, we were trying to unify a few different sorts of packages. Coming from SpaceWalk, part of the team was used to wokring on RPMS with the RPM Database for storage, and Yum as the mechanism for fetching them. The other part of the team was coming from the JBoss side, working with JAR, WAR, EAR and associated files, and the Ivy or Maven building and fetching the files. We were working within the context of the Red Hat Network (as it was then called) for delivering content to subscribers. Thus, we had the concept of Errata, Channels, and Entitlements which are somewhat different from what other organizations call these things, but the concepts should be general enough to cover a range of systems. There are many gaps in this diagram. It does not discuss the building of packages, nor the relationship between source and binary packages. It also does not provide a way to distinguish between the package storage system and the package fetch mechanism. But the bones are solid. I’ve used this diagram for a few years, and it is useful.

Review: AcademiX GNU/Linux 2.2

What sets AcademiX apart from other distributions is the EDU software manager. This package manager provides curated lists of educational software, which are grouped by subject and by age range. This package manager makes finding educational software really easy. There is software for astronomy, biology, geography, foreign languages, and many other subjects. While there are gaps in the availability of applications covering various subjects, that is a gap in the broader open source application ecosystem, not something specific to AcademiX. While some of the rough edges I noted with the installation process and the desktop customization make me a hesitant to recommend AcademiX to new Linux users, Educational Technology professionals should perhaps try out AcademiX just to use the EDU package manager to explore various open source applications. While installing and updating software was easy and basically the same experience as any other modern, Debian-based distribution, the fact that some of the packages come from servers in Romania means that some package downloads can be much slower than downloading from the world-wide network of Debian mirrors. For individual packages and small collections of packages this is not too noticeable, but it is still an issue. The frustrating part is the fact that the speeds are not consistent. Sometimes I was downloading at only 40kbps, but other times it was much faster. I experienced the same issue when trying to download the ISO. One download took about 20 minutes for the 1.7GB image but some other attempts took 4 hours. Final thoughts AcademiX GNU/Linux is an interesting distribution, but it has some rough edges that need to be cleaned up. Honestly, I really, really wanted to like this distribution (good distributions aimed at the educational market are always needed), but found it to be merely okay. AcademiX has a lot of potential, but it is just not there yet. DebianEdu/Skolelinux is far more polished while serving almost the exact same niche. However, if the AcademiX team cleans up some of the issues I noted above, especially the installer issues, I think future versions of AcademiX might turn out to be worthwhile. The EDU software installer is well organized and aids in discovering educational software, so that is one solid advantage AcademiX offers, but overall the distribution needs more work and polish before I could move it from "this distribution is okay" to "you should give this distribution a try".

Security: ECB, Bluetooth and AppArmor Crash Course

  • ECB server hacked – Data disclosure of the European Central Bank – Bank hacks from Mexico to Bangladesh

    The Europeans probably do not even know about „what is going on“ and according to ex finance minister of Greece – finance ministers do not have a lot to say in the ECB – the IMF has – there are no recordings of the meetings of „The Eurogroup“ – so transparency over decision making processes is rather bad. After all just like the (more or less ideal) „big brother“ the FED it is not under direct democratic influence – does what it wants – every word the FED CEO says is analyzed and influences financial market decisions. „One of the sites of the European Central Bank (ECB) has been hacked. The attackers gained access to sensitive users ‚ information, however, the internal system of the Bank has not been compromised.

  • FrOSCon 2019 - openSUSE booth & AppArmor Crash Course

    Last weekend, I was at FrOSCon - a great Open Source conference in Sankt Augustin, Germany. We (Sarah, Marcel and I) ran the openSUSE booth, answered lots of questions about openSUSE and gave the visitors some goodies - serious and funny (hi OBS team!) stickers, openSUSE hats, backpacks and magazines featuring openSUSE Leap. We also had a big plush geeko, but instead of doing a boring raffle, we played openSUSE Jeopardy where the candidates had to ask the right questions about Linux and openSUSE for the answers I provided.

Manjaro 18.0.4 Illyria Xfce review - Nice but somewhat crude

Overall, Manjaro 18.0.4 Illyria Xfce is a decent distro. It has lots of good and unique points. Network, media and phone support is good. You get a colorful repertoire of high-quality programs, the performance and battery life are excellent, and the desktop is fairly pretty. The system was also quite robust and stable. But then, there were issues - including inconsistent behavior compared to the Plasma crop. The installation can be a bit friendlier (as Plasma one does). The package management remains the Achilles' Heel of this distro. Having too many frontends is confusing, and none of them do a great job. The messages on dependencies, the need for AUR (if you want fancy stuff), and such all create unnecessary confusing. There were also tons of visual papercuts, and I struggled getting things in order. All in all, Manjaro is getting better all the time, but it is still too geeky for the common person, as it breaks the fourth wall of nerdiness too often. 7/10, and I hope it can sort itself out and continue to deliver the unique, fun stuff that gets sidelined by the rough edges.
