Tumbleweed: Comparing your local version with the on-line versions

Posted by jpluimers on 2018/04/05

Comparing your local version with the on-line versions

Before upgrading a Tumbleweed system, it makes sense to check which is your local and which is the on-line version. This is actually a tad more complicated than it sounds.

There are three versions involved:

There is a mismatch between the last two as a side effect of decoupling the arm port a bit from the high checkin frequency of openSUSE:Factory; ARM simply has not enough power to build the snapshot in the same time Intel and PowerPC can do.

[WayBack] Dominique a.k.a. DimStar (Dim*) – A passionate openSUSE user thinks the last two are mismatched is a side effect off [WayBack] osc service remoterun operates on outdated sources (product builder) · Issue #4768 · openSUSE/open-build-service · GitHub.

He also tech-reviewed this post.

Your local release version

There are various ways to get your local version:

The easiest is to inspect the file  /etc/os-release, for instance 20180208 in the file content:

NAME="openSUSE Tumbleweed"
# VERSION="20180208 "
ID=opensuse ID_LIKE="suse"
VERSION_ID="20180208"
PRETTY_NAME="openSUSE Tumbleweed"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:tumbleweed:20180208"
BUG_REPORT_URL="https://bugs.opensuse.org"
HOME_URL="https://www.opensuse.org/"

You can also perform rpm --query --provides openSUSE-release | grep "product(openSUSE)" which for the same install returned this product(openSUSE) = 20180208-0.

Finally, you can use zypper to query the installed product which also includes the version:

$ zypper search --installed-only --type product --details
Loading repository data...
Reading installed packages...

S  | Name     | Type    | Version    | Arch    | Repository       
---+----------+---------+------------+---------+------------------
i+ | openSUSE | product | 20180228-0 | aarch64 | (System Packages)

The on-line release version

I will explain this for the aarch64 architecture, but the mechanism holds for all architectures, it is just that the directory names vary.

Architectures and base directories you can use this mechanism with:

Each architecture contains the version number in two kinds of places:

  1. The content of the repository meta data in a file named *-primary.xml.gz referenced from repomd.xml in the repodata subdirectory
  2. The filename of a package named ?P=openSUSE-release-2*

Back to the aarch64 architecture:

The on-line build version

I will explain this for the aarch64 architecture, but the mechanism holds for all architectures that build on openQA, it is just that the directory names vary and not all architectures are running on openQA.

Architectures and base directories you can use this mechanism with:

Architectures not on openQA:

  • armv6hl
  • armv7hl

Each platform contains the version number in two kinds of places:

  1. The content of the repository meta data in the file named media.1/media and media.1/products
  2. Names used in the openQA links

Back to the aarch64 architecture on the ARM platform:

From the #AllesIstKaput department: DNS 1.1.1.1 is unusable for many; 9.9.9.9 has government affiliation

Posted by jpluimers on 2018/04/04

Abstract from this morning’s Twitter feed:

  • 1.1.1.1 [Wayback] DNS is broken in many areas (because of for instance AT&T, Vodafone, Cisco screwing up and 1.1.1.1 historically being marked for research purposes)
  • 9.9.9.9 [Wayback] DNS has government affiliation (owned by Quad9, but the partner list below does not look nice)

So what’s left?

There are a more interesting IPv4 addresses untaken for DNS, but I’m not sure they are likable enough:

Where am I?

Posted by jpluimers on 2018/04/03

Google is smart; you can ask it https://www.google.com/search?q=what%27s+my+location

This is accurate enough for many uses (it’s off for a couple of kilometers):

curl "https://maps.googleapis.com/maps/api/browserlocation/json?browser=firefox&key=AIzaSyDBgL8fm9bD8RLShATOLI1xKmFcZ4ieMkM&sensor=true"

Some links about the above API:

DNS traffic monitoring tools: tshark, tcpdump or dnstop

Posted by jpluimers on 2018/04/02

I resolved my issue with tshark, but that’s not available on all systems neither is dnstop. Most systems do have tcpdump though.

Anyway, some links:

The origin of the space between in the “Heineken Brouwerij” logo of the Amsterdam brewery

Posted by jpluimers on 2018/04/02

On the very early adoption of the spacing in the typography:

Ooit wel eens stilgestaan bij het iets te grote gat tussen de woorden Heineken en Brouwerij op de Stadhouderskade? Of waarom de belettering op bruggen in de stad zo ‘Amsterdams’ aandoet? Waarschijnlijk niet. Typograaf Bas Jacobs deed dat wel. Zijn ontdekkingen bundelde hij in een speciale toeristengids.

A small book (just EUR 15) tells you more about his Amsterdam findings: Safari Typo Amsterdam

Exclusive: The Silicon Valley quest to preserve Stephen Hawking’s voice – San Francisco Chronicle

Posted by jpluimers on 2018/04/01

Long read: [WayBackExclusive: The Silicon Valley quest to preserve Stephen Hawking’s voice – San Francisco Chronicle

Eric Dorsey, a 62-year-old engineer in Palo Alto, was watching TV Tuesday night when he started getting texts that Stephen Hawking had died. He turned on the news and saw clips of the famed physicist speaking in his iconic android voice – the voice that Dorsey had spent so much time as a young man helping to create, and then, much later, to save from destruction. Dorsey and Hawking had first met nearly 30 years earlier to the day. In March 1988, Hawking was visiting UC Berkeley during a three-week lecture tour. At 46, Hawking was already famous for his discoveries about quantum physics and black holes, but not as famous as he was about to be.

Urgent security advisory – MikroTik – upgrade to 6.41.3 if you can change your bridge implementation, ensure SMB and WWW are not WAN accessible

Posted by jpluimers on 2018/03/31

I both understand the [WayBack] Urgent security advisory – MikroTik and the users reluctant to upgrade: Mikrotik has a history of updates breaking existing behaviour and underdocumenting features and release notes.

The attack is over the www or www-ssl services which by default run on port 80 and 443. You can see on which networks they are bound using this example from the terminal:
