Reminder to self: check if FritzOS 7.50 has become available for Fritz!Box 7490

Posted by jpluimers on 2023/03/31

This post is a reminder to myself to check if Fritz!Box 7490 can be upgraded to the FritzOS (sometimes spelled Fritz!OS or FRITZ!OS) 7.50, which is the firmware that introduced WireGuard on various Fritz!Box models.

Initially it wasn’t available for the wildly popular Fritz!Box 7490 series which, at the time of writing was still a current Fritz!Box model, has been very popular in The Netherlands because of (now defunct) internet provider XS4ALL started shipping it to customers almost 10 years ago ([Wayback/Archive] Property:XS4ALL – BoxMatrix). Currently Fritz!Box products are offered by KPN, Solcon and Freedom Internet.

So I asked [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on Twitter: “Is there any information if (and hopefully estimate when) the @AVM_NL @AVM_DE 7.50 firmware is going to be available for the (in The Netherlands very well sold/distributed) Fritz!Box 7490 model? FritzOS 7.50 supports @WireGuardVPN: a big step forward.”

UniFi – Install a UniFi Cloud Controller on Amazon Web Services – Ubiquiti Networks Support and Help Center

Posted by jpluimers on 2023/03/06

I was not aware you could this: [WayBack] UniFi – Install a UniFi Cloud Controller on Amazon Web Services – Ubiquiti Networks Support and Help Center

Giving it a bit more thought, I’m not sure I would want this, as it would presume you have an internet connection that is up on the WAN side.

You’d need this before installing any of your Unify equiment, even when installing your first Unify router, which would mean a chicken and egg problem.

Also it would mean you can only use the cloud key when the WAN is down, you cannot use the cloud-key, not even locally.

Wireshark Cheat Sheet – Commands, Captures, Filters, Shortcuts

[Wayback/Archive] Wireshark Cheat Sheet – Commands, Captures, Filters, Shortcuts

It is available both a huge [Wayback/Archive] jpg (2500×2096 pixels), so it already prints well on A5 or A4 sized paper for reference and as a [Wayback/Archive] PDF (so you can print it on even larger paper sizes).

PoE Secret Strengths – Danny Thorpe

Posted by jpluimers on 2023/02/15

Passed away, this makes still every good reading: [Wayback/Archive] PoE Secret Strengths – Danny Thorpe.

I wish both Danny and his site were still alive.

Power over Ethernet (PoE) is a standard (802.3af) for powering devices using voltage carried on “spare” wires in the Ethernet cable.  For devices that support being powered by PoE, it means you only need one cable to the device to connect it to network and provide power.  Only one cable to snake through walls and attics, and the device can be placed without regard to access to a power outlet.

PoE is rightfully marketed to business IT and is particularly well suited to devices such as IP security cameras, wireless access points, and IP phones. Unfortunately, targeting the business IT audience meant the devices tended to be a lot more expensive than consumer equivalents.

That is now changing. I’m finding a fair number of PoE PSE switches (PSE = Power Source Equipment, that supply power on the Ethernet wire) and PoE PD devices (PD = Powered Device) in the consumer price range.  They’re still listed under “business networking” rather than “home networking”, but at least they exist.

He mainly used Netgear PoE switches; I like the MikroTik ones better.

Note there are many Power over Ethernet standards and they have evolved over time. See Source: Power over Ethernet: Standard implementation – Wikipedia

Isotopp’s home sensor network

Posted by jpluimers on 2022/11/25

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:

  1. No cloud. We are running all services locally.
  2. 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 had some Windows ATOM issues before, but this beats them easily

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.

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).
