Uptime Robot SMTP check is not service-specific (yet) but a TCP check…

Posted by jpluimers on 2018/04/11

When you use the check on the SMTP port, note that [WayBack] Uptime Robot on Twitter: “Yes, it is not service-specific (yet) but a TCP check.… “.

It does to full DNS protocol checks from IP address though, so I am glad about that.

via: [WayBack] Jeroen Pluimers on Twitter”@uptimerobot I have the impression that the SMTP port check does not really check anything but the port being open. Had a flaky mail server that would react on the TCP level, but timed out on the SMTP level. Uptimerobot did not notice that.”

beep, patch and ed – The Isoblog.

Posted by jpluimers on 2018/04/11

So we are all doomed: on debian, beep was an issue leading into a CVE. The fix is an issue too, and also has a CVE.

CLIFF Electronic Components – Quicktest; Resistance wheel

Posted by jpluimers on 2018/04/11

[WayBack] CLIFF Electronic Components – Quicktest:

The Quicktest is ideal for electrical shops, factories, labs and service departments.

With its lid open the wires of a plugless lead can be inserted into the insulated clips. When the lid is closed, current passes to the equipment being demonstrated or tested.

A neon light shows that the connector is live and ready to use. The fuse (BS 1362) is easily accessible for replacement.

The connector is made of tough, safe materials. The base is phenolic moulded for insulation and rigidity. The lid is flame retardant glass filled thermo plastic.

The insulated clips are colour coded for easy identification. The flexible cable grip will take any normal mains cable. Only one small screwdriver is needed for both the base entry and the terminal screws.

Another handy tool is this: [WayBack] Resistance Wheel | Jaycar Electronics, but it’s hard to get so you can build similar devices yourself with a few hours of work:

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:
