Roughly following book order:”.

Since about 5 months now, there has been a new Chocolatey package maintainer for OpenVPN

Posted by jpluimers on 2022/08/26

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).

FRITZ!Box 7490/7390 comparisions (via: Vergleich AVM FRITZ!Box 7490 und FRITZ!Box 7390 – YouTube)

Posted by jpluimers on 2022/08/12

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 [WaybackUSB over LAN in more detail, especially the [Waybackopen source project USB IP.

In some countries @archiveis redirect their domains using http-302 which can have trouble with multi-WAN

Posted by jpluimers on 2022/08/12

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.

TL;DR

Modifying the routing table so traffic for 54.37.18.234 goes to WAN1 was my solution.

Finding the destination address

Fritzbox 7490 ISDN landline and intenral ISDN S0 bus links

Posted by jpluimers on 2022/08/08

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
