LXer: How to deploy Kubernetes on the Raspberry Pi

Tuesday 21st of March 2017 02:12:53 PM
When I became interested in ARM devices, and in the Raspberry Pi in particular, my first project was an OpenVPN server.By having the Raspberry Pi as a secure gateway to my home network, I could use my phone to control my desktop and remotely play Spotify, open documents, and a bunch of other fun things. I used an existing tutorial for that first project because I was afraid of piping anything into the command line on my more Diversity Makes Projects More Successful

Tuesday 21st of March 2017 02:00:06 PM

Open source projects are by their nature intended to be welcoming, pulling in contributions from many different volunteers. But in reality, open source and the tech industry in general often lack diversity. Speaking at the Open Source Leadership Summit in February, Mozilla’s Chief Innovation Officer Katharina Borchert told the crowd that working to bring ethnic, gender, and skill diversity to open source projects isn’t just the right thing to do because of moral grounds, it’s the right thing to do to make projects more successful.

Reddit: Office 365 Onedrive looks at user-agent to determine performance.

Tuesday 21st of March 2017 01:21:34 PM

For a few weeks I have Linux Mint 18.1 installed on my laptop. I am still in school and started a new project. With that project we use onedrive on a Office 365 platform. On my laptop I use the latest Firefox 52 browser and strictly work in Word online since document compatibilty is always an issue while working in a team.

Sadly enough I experienced a lot of performance issues while browsing the directory and working on a document. As I also have a desktop running Windows 10 and the same Firefox 52 browser I tried working on that and see if the problem persists. But no. The problem was no more.

Then I began thinking and trying a few different things. On of the first ideas I came up with was changing the user-agent string. I changed the user-agent string to the following.

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/52

I the following extension in Firefox to change it.

After changing the user-agent the performance problems were resolved. The UI of OneDrive worked flawlessly. The only thing in the user-agent changed was the OS. At first I thought this was a random occurance but no. I changed back to the normal user-agent and the problem came back.

My friend who also had this problem used the same method as I did with the same results.

So by writing this I hope to get to know if people also have this issue.

Reddit: How do control characters happen?

Tuesday 21st of March 2017 01:20:49 PM

A discussion over at /r/vim dug up some memories of try drivers, line discipline and chat devices that I have only a passing familiarity with.

With the title question what I'd really like to do is trace the exact code paths as much as possible from when I press Ctrl + [ to when the application gets the ESC character sent to it.

In my head, the high level flow is something like this

  1. IRQ from keyboard hardware
  2. Keyboard character device does stuff with scancodes
  3. Line discipline stuff
  4. TTY drivers does magic like handle signals
  5. Application receives ASCII control character

What I don't know at all is where the scancode or keycode combinations get translated into the appropriate ASCII.

I have a copy of the Linux git tree laying around and would like to trace the whole code path for this kind of thing, but I just don't know enough to get started.

Any pointers would be really welcome.

TuxMachines: Security Leftovers

Tuesday 21st of March 2017 12:27:13 PM
  • Security updates for Monday
  • Old Linux kernel security bug bites

    OK, hands up, who knows what High-Level Data Link Control (HDLC) is? It's an archaic networking data framing protocol that's used in modems, X.25, frame-relay, ISDN, and other now uncommon networking technologies. I know it because I used to work with them back in the day. You'll get to know it now because a researcher discovered a security hole hidden within the Linux kernel driver that implements it.

  • Seven year-old Linux vulnerability now patched

    An old vulnerability was just discovered in the Linux kernel, potentially allowing hackers to gain privilege escalation, or cause a denial of service. The vulnerability was quickly fixed and there have been no signs of it in the wild, although that does not necessarily mean it went unnoticed.

  • OpenSSH 7.5 released

    OpenSSH 7.5 has just been released. It will be available from the mirrors listed at shortly.

  • OpenSSH 7.5 Has Security Fixes, Removes OpenSSL 1.0 Support for Portable OpenSSH

    OpenSSH, the cross-platform and open-source 100% complete SSH 2.0 protocol implementation offering both SFTP server and client support was updated today to version 7.5.

    OpenSSH 7.5 comes three months after the release of OpenSSH 7.4 in late December 2016, and promises to be a maintenance update that addresses two important security issues, implements support for the "=-" syntax to make removing of methods from algorithm lists a lot easier, and fix numerous reported bugs.

  • Is Linux Mint a secure distribution?

    Linux Mint has been lambasted by some in the media for security problems over the last few years. But how accurate are such perceptions? Does Linux Mint really suffer from security problems or is it all much ado about nothing?

    A writer at DistroWatch wades into the controversy and examines some of the myths and misunderstandings about Linux Mint and security.

  • Linux Mint's security record

    Some of the more common misunderstandings I have encountered recently have involved the Linux Mint distribution. Mint has been a popular project in recent years and, with many people using the distribution and talking about the project, there is bound to be some mis-communication. In particular, most of the rumours and misunderstandings I have encountered have revolved around Mint's security practises and history. I would like to clear up a few of the more common rumours.

  • Mozilla Firefox is the First Pwn2own 2017 Victim to be Patched

    Some vendors respond to security issues faster than others. Last week, the 10th annual Pwn2own hacking challenge was hosted by Trend Micro's Zero Day Initiative (ZDI), with multiple groups of researchers taking aim at web browsers, operating systems and virtualization technology.

    Mozilla's Firefox web browser was successfully exploited on March 16, the second day of the Pwn2own event. Researchers from Chaitin Security Research Lab were the only group to attack Mozilla Firefox, and earned $30,000 for demonstrating a new zero-day exploit. The day the exploit was demonstrated, the only thing publicly revealed about the exploit is that it made use of an integer overflow flaw in combination with an uninitialized memory buffer in the Windows kernel.

Reddit: (x-post from /r/software) Could someone suggest a personal wiki?

Tuesday 21st of March 2017 10:42:46 AM

Hi, I am a researcher and I need a personal wiki to store different bits and pieces of information for my own reference later. I am looking for a software that:

  1. [Essential] Available on MacOS and Linux. Windows would be a good addition as well, but not critical.

  2. [Essential] Allows to store text (obviously) and images.

  3. [Essential] Allows to include code blocks into notes (with syntax highlighting).

  4. [Important] Could be used as a daily journal/electronic lab notebook (ELN).

  5. [Important] Makes it easy to sync notes between several machines.

  6. [Important] Not abandoned by its developer.

  7. [Not essential] Supports Markdown.

Zim Desktop Wiki almost ideally fits my requirements, but I cannot get it working under MacOS 10.12 (Sierra). Also, it seems that the program has not been updated for several years. CherryTree looks like a good alternative, but there is no MacOS version. OneNote doesn't have code highlighting and only available as online (slow) app on Linux. I dislike Tiddlywiki for some reason, probably for its layout.

Would be grateful for any other suggestions, thanks.

    I am a massive fan of 'Avorion' [Steam] as this Early Access space sandbox has a lot going for it and it just got a major update. I am also considering setting up a GOL server for it!

    This new update will mean a re-design of your ships, so be warned. The flight model has been reworked and you now need to make use of three new blocks: Directional Thruster, Gyro Array, Inertia Dampeners.

openSUSE Tumbleweed: A Linux distribution on the leading edge

So, to summarize: openSUSE Tumbleweed is a good, solid, stable Linux distribution with a wide range of desktops available. It is not anything particularly exotic or unstable, and it does not require an unusual amount of Linux expertise to install and use on an everyday system. To make a very simple comparison, in my experience installing and using Tumbleweed is much less difficult and much less risky than using the Debian "testing" distribution, and it is kept much (much much) more up to date than openSUSE Leap, Debian "stable", Linux Mint or Ubuntu. I don't say that to demean any of those other distributions. As I said at the end of my recent post about point-release vs. rolling-release distributions, if your hardware is fully supported by one of those point-release distributions, and you are satisfied with the applications included in them, then they are certainly a good choice. But if you like staying on the leading edge, or if you have very new hardware which requires the latest Linux kernel and drivers, or you just want/need the latest version of some application (in my case this would be digiKam), then openSuSE could be just what you want.
