For my link archive an interesting blog post by isotopp (Kristian Köhntopp)
[Wayback] My home sensor network
I have been asked to document my home sensor network. Being married to a person with a background in web security sets boundary conditions:
- No cloud. We are running all services locally.
- No control, only metrics.
I am collecting data from a number of plugs with power meters over Wifi, using the MQTT protocol. I am also collecting data from a number of temperature sensors over Zigbee, and convert to MQTT. The MQTT data is ingested into Influx, and then read and plotted in Grafana. All of this is dockered and runs locally on an Ubuntu server.

I’ve had some issues with Windows ATOM tables filling up, but nothing like this security bypass:
A new Windows code injection technique, atombombing, which bypasses current security solutions.

Last winter, I discovered that the OpenVPN version on Chocolatey was really old: it had not been updated since 2019.
Most Chocolatey maintainers are volunteers and sometimes the burden can become too large. Back then the maintainer was [Wayback/Archive] Chocolatey Software | wget, but luckily [Wayback/Archive] Chocolatey Software | dgalbraith has stepped in and in March 2022 bumped the version from [Wayback/Archive] Chocolatey Software | OpenVPN 2.4.7 to [Wayback/Archive] Chocolatey Software | OpenVPN – Open Source SSL VPN Solution 2.5.4 and kept maintaining (currently there is [Wayback/Archive] Chocolatey Software | OpenVPN – Open Source SSL VPN Solution 2.5.7).

Not sure why WordPress.com failed to post this on 20140525, so I put it in the scheduler again. In the end I got a Fritz!Box 7490 and though the
In 2013, [Wayback] Fritz!Box replaced the 7390 top model with the 7490 and I [Wayback] might get get soon when ADSL (which still has a Fritz!Box 7240 attached) is upgraded to fiber.
So here are some differences partially from the English FRITZ!Box and German FRITZ!Box Wikipedia page between the [Wayback] Fritz!Box 7390 and [Wayback] Fritz!Box 7490, partially from the below video:
About cooling: according to the video both run the same temperature, either because the air cooling of the 7490 is better. I’m wondering if that is the same when running inside a closet.
[Wayback/Archive.is] HardwareInfo.nl has a Fritz!Box 7490 review that indicates 802.11ac and USB3 might not be as fast as you’d hope.
Reading the [Wayback/Archive.is] Amazon.de 7490 reviews, I might just ask xs4all to get me a 7390, not a 7490.

PS: I need to research [Wayback] USB over LAN in more detail, especially the [Wayback] open source project USB IP.

From [Wayback Archive.is blog — Why has the URL “archive-li” changed to…:
Why has the URL “archive-li” changed to “archive-ph”, and will this affect saved bookmarks at any time in the future?
Anonymous
This is temporary and only for some countries. All 7 domains work, so you do not need to change the bookmarks.
In The Netherlands all Archive Today domains redirect to archive.ph using a HTTP 302 redirect.
This caused trouble at my home location, but not at my brother, so I searched for local issues.
In the end, it was because I have dual WAN as network load balancing at home.
Modifying the routing table so traffic for 54.37.18.234 goes to WAN1 was my solution.

Somehow WordPress.com failed to post it on the scheduled date 20150331, not sure why.
Though ISDN has been phased out in The Netherlands as and almost phased out in Germany, you can still use end user Terminal Equipment on the internal S-bus.
Since scheduling the post for 2015, the same information as the original diagram below appeared in text form on Wikipedia and there it also adds TAE connector information: Fritz!Box: Belegung der kombinierten DSL-Telefon-Buchse – Wikipedia
Die Anschlussbelegung der Kombibuchse ist wie folgt:[44]
- Pin 1: ISDN 1a
- Pin 2: ISDN 1b
- Pin 3: analog La
- Pin 4: DSL
- Pin 5: DSL
- Pin 6: analog Lb
- Pin 7: ISDN 2a
- Pin 8: ISDN 2b
Der RJ-45-Stecker am grauen DSL-Zweig des Y-Kombikabels zeigt folgende Belegung:[44]
- Pin 4: DSL
- Pin 5: DSL
Die übrigen Pins sind unbenutzt.
Am schwarzen Telefonzweig ist der RJ-45-Stecker folgendermaßen belegt:
- Pin 1: analog La
- Pin 2: frei
- Pin 3: ISDN 2a
- Pin 4: ISDN 1a
- Pin 5: ISDN 1b
- Pin 6: ISDN 2b
- Pin 7: frei
- Pin 8: analog Lb
Somit ist ein direkter Anschluss an ISDN möglich, für analoge Anschlüsse liegt für Deutschland ein Adapter auf TAE bei:
- Pin 1 RJ-Buchse auf Pin 1 TAE
- Pin 8 RJ-Buchse auf Pin 2 TAE
Ein normales Kabel mit TAE-Stecker und sechspoligem RJ-Stecker, wie es für den Anschluss analoger Telefone an eine TAE-Dose verwendet wird, funktioniert nicht.
Bei entbündelten Anschlüssen (ohne analoges oder ISDN-Telefon) kann ein direktes Kabel verwendet werden.
Das Kabel für deutsche Anschlüsse:
- Pin 4 RJ-Stecker auf Pin 1 TAE
- Pin 5 RJ-Stecker auf Pin 2 TAE

I tried the solution in [Wayback/Archive.is] Fritz!box 7590 interface extremely slow : fritzbox (remove the some 30-40 unused machines from the network overview), but it didn’t matter: since Fritz!OS 7.x, the Fritz!Box 7490 UI is just very very slow: each page takes 10+ seconds to load.
Hopefully I can get rid of these and move to pfSense based hardware eventually.
