Is a raspberry pi 1 good enough for a pihole server? : pihole

Posted by jpluimers on 2018/04/10

Many people use it that way. Which means I can put it on an old Raspberry Pi B+ revision 1.2 board (which Wikipedia indicates as the B 1+ in the Specifications table but as Raspberry Pi 1 Model B+ revision 1.2 in the schematics of connectors).

I might consider DietPi as distribution (which is Debian based) as it is even ligher.

See [WayBack] https://www.reddit.com/r/pihole/comments/6h39zr/is_a_raspberry_pi_1_good_enough_for_a_pihole/#divw0i5

One more note: I need to check out which Debian base name (which indicates the version) works best as there seemed to be a dnsmasq issue (not archived because discourse hatesdislikes the WayBack machine and Archive.is):

Like Apple, Android and Delphi, they use name based versions of which I always forget the order of. Luckily the source of the below table gets updated over time [2017 Archive.is, 2018 Archive.is] Debian releases and names – Electric Toolbox Debian releases are named after characters from Toy Story and are frequently referred to with the name rather than the version.:

Version Code name Release date Toy Story character
1.1 Buzz 1996-06-17 Buzz Lightyear
1.2 Rex 1996-12-12 Rex (the T-Rex)
1.3 Bo 1997-06-05 Bo Peep
2.0 Hamm 1998-07-24 Hamm (the pig)
2.1 Slink 1999-03-09 Slinky Dog
2.2 Potato 2000-08-15 Mr Potato Head
3.0 Woody 2002-07-19 Woody the cowboy
3.1 Sarge 2005-06-06 Sarge from the Bucket O’ Soldiers
4.0 Etch 2007-04-08 Etch, the Etch-A-Sketch
5.0 Lenny 2009-02-14 Lenny, the binoculars
6.0 Squeeze 2011-02-06 Squeeze toy aliens
7 Wheezy 2013-05-04 Wheezy the penguin
8 Jessie 2015-04-26 Jessie the cowgirl
9 Stretch 2017-06-17 Rubber octopus from Toy Story 3
10 Buster not yet released Andy’s pet dog
11 Bullseye Not yet released Woody’s horse
Sid “unstable” The next door neighbour

Git repository with fixed binaries for Tumbleweed on Raspberry Pi 3 – Bug 1084419 – Glibc update to 2.27 causes segfault during name resolution

Posted by jpluimers on 2018/04/08

OSC downloads for [archive.is] https://bugzilla.opensuse.org/show_bug.cgi?id=1084812

The binaries provided by Stefan Brüns, together with installation instructions are now in a git repository at [WayBack] wiert.me/public/linux/opensuse/tumbleweed/aarch64 a.k.a. arm64/1084182-fix-osc-binaries · GitLab.

Follow the steps in Applying the fixes on a broken system to at least temporarily get your system to work (a new zypper dist-upgrade might fail, so be careful with that).

The cause was some ARM A53 errata handling:

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:
