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.

Early june, I blogged about Wake-on-LAN from a Windows machine.
My plan was to adopt [Wayback/Archive.is] Wake.ps1 into Wake-on-LAN.ps1 (as naming is important).
One of the goals was to support multiple hardware MAC address formats, especially as Wake.ps1 had the below comment, but did support the AA-BB-CC-DD-EE-FF, though not the AA:BB:CC:DD:EE:FF hardware MAC address format:
<# ... .NOTES Make sure the MAC addresses supplied don't contain "-" or ".". #>
A colon separated hardware MAC address would result in this error inside the call to the [Wayback/Archive.is] PhysicalAddress.Parse Method (System.Net.NetworkInformation) | Microsoft Docs:
Send-Packet : Exception calling "Parse" with "1" argument(s): "An invalid physical address was specified."
So I did some digging, starting inside the above mentioned blog post, and adding more:
Parse method in the [Wayback/Archive.is] PhysicalAddress.cs source code in C# .NET, which contains code like this://has dashes? if (address.IndexOf('-') >= 0 ){ hasDashes = true; buffer = new byte[(address.Length+1)/3]; }
xx:xx:xx:xx:xx:xx(canonical)xx-xx-xx-xx-xx-xx(Windows)xxxxxx-xxxxxx(Hewlett-Packard switches)xxxxxxxxxxxx(Intel Landesk)
I should rename the first one IEEE 802, as per this:
The standard (IEEE 802) format for printing EUI-48 addresses in human-friendly form is six groups of two hexadecimal digits, separated by hyphens (
-) in transmission order (e.g.01-23-45-67-89-AB). This form is also commonly used for EUI-64 (e.g.01-23-45-67-89-AB-CD-EF).[2] Other conventions include six groups of two hexadecimal digits separated by colons (:) (e.g.01:23:45:67:89:AB), and three groups of four hexadecimal digits separated by dots (.) (e.g.0123.4567.89AB); again in transmission order.[30]
The latter is used by Cisco (see for instance [Wayback/Archive.is] Cisco DCNM Security Configuration Guide, Release 4.0 – Configuring MAC ACLs [Support] – Cisco and [Wayback/Archive.is] Cisco IOS LAN Switching Command Reference – mac address-group through revision [Support] – Cisco), so another format to add:
xxxx.xxxx.xxxx(Cisco)
The
addressparameter must contain a string that can only consist of numbers and letters as hexadecimal digits. Some examples of string formats that are acceptable are as follows:
00112233445500-11-22-33-44-550011.2233.445500:11:22:33:44:55F0-E1-D2-C3-B4-A5f0-e1-d2-c3-b4-a5Use the GetAddressBytes method to retrieve the address from an existing PhysicalAddress instance.
I really do not have all the sources for the various representations for 48-bit MAC addresses, but I have seen them variously used:
AA-BB-CC-DD-EE-FF AA.BB.CC.DD.EE.FF AA:BB:CC:DD:EE:FF AAA-BBB-CCC-DDD AAA.BBB.CCC.DDD AAA:BBB:CCC:DDD AAAA-BBBB-CCCC AAAA.BBBB.CCCC AAAA:BBBB:CCCC AAAAAA-BBBBBB AAAAAA.BBBBBB AAAAAA:BBBBBB
From the last list, which is far more complete than the others, I recognise quite a few from tools I used in the past, but too forgot the actual sources, so I took the full list from there and tried to name them in parenthesis after the links I found above and what I remembered:
AABBCCDDEEFF (Bare / Landesk)AA-BB-CC-DD-EE-FF (IEEE 802 / Windows)AA.BB.CC.DD.EE.FF (???)AA:BB:CC:DD:EE:FF (Linux / BSD / MacOS)AAA-BBB-CCC-DDD (???)AAA.BBB.CCC.DDD (Cisco?)AAA:BBB:CCC:DDD (???)AAAA-BBBB-CCCC (???)AAAA.BBBB.CCCC (Cisco / Brocade)AAAA:BBBB:CCCC (???)AAAAAA-BBBBBB (Hewlett-Packard networking)AAAAAA.BBBBBB (???)AAAAAA:BBBBBB (???)Some additional links in addition to the ones above:

Last month, I wrote

The thread was by Jeff Geerling on Twitter: “I plug computers into my computers…”.
Jeff followed up on this much sooner than I expected with [Wayback/Archive] Jeff Geerling on Twitter: “Hey look! That computer inside a computer thing is real now! It’s the PCIe version of the Blicube KVM: …”

It would also very much match the below issue that Jeff raised:

Hey macOS desktop in the basement, thanks for going to sleep while I was in the middle of typing at you via SSH.
Maybe that should be a signal not to sleep, eh?
$ sudo wakeonlan ac:87:a3:19:7e:81
Sending magic packet to 255.255.255.255:9 withWell, at least that works.

Sometimes it is easier to have current and public CA signed TLS certificates for internal servers than to setup and maintain an internal CA and register it on all affected browsers (including mobile phones).
One of my reasons to investigate this is that Chrome refuses to save credentials on servers that have no verifiable TLS certificate, see my post Some links on Chrome not prompting to save passwords (when Firefox and Safari do) about a week ago.
Below are some links for my link archive that hopefully will allow me to do this with Let’s Encrypt (msot via [Wayback/Archive] letsencrypt for internal servers – Google Search):
