sslh accepts connections on specified ports, and forwards them further based on tests performed on the first data packet sent by the remote client.
Probes for HTTP, SSL, SSH, OpenVPN, tinc, XMPP are implemented, and any other protocol that can be tested using a regular expression, can be recognised. A typical use case is to allow serving several services on port 443 (e.g. to connect to ssh from inside a corporate firewall, which almost never block port 443) while still serving HTTPS on that port.
Hence sslh acts as a protocol demultiplexer, or a switchboard. Its name comes from its original function to serve SSH and HTTPS on the same port.
sslh supports IPv6, privilege dropping, transparent proxying, and more.
Interesting…

I had the same issue as in sleep wake – Macbook Air – battery drains while sleeping (but not when shut down) – Ask Different which suddenly introduced itself in April 2016 after I had been running El Capitan (OS X 10.11) for a while.
The Mac didn’t have PowerNap active as I verified using How Power Nap works on your Mac – Apple Support
At first it looked like an SMC reset worked as explained by Reset the System Management Controller (SMC) on your Mac – Apple Support and mentioned in Mac Air loses 90% of battery overnight when in … | Apple Support Communities.
The Mac is indeed running Chrome, but I don’t like to turn that off before sleeping.
Executing pmset -g would show hibernatemode 3.
So I opted for the hibernate option as mentioned in the first link:
sudo pmset -a hibernatemode 25
This will take a bit longer to restore the memory from hibernate state, but saves a lot of frustration.

Eerder dit jaar testen we 3d-printers die voor minder dan 1000 euro te koop zijn. Het kan echter nog goedkoper. Dit keer testen we vier 3d-printers die ongeveer 300 euro kosten.

The big G+ news this week was that they brought back search, years after they made the G+ search useless, so jokes like at [WayBack] Ikey Doherty – Google+ “Remember when G+ search was useful?” finally can be left behind us.
Now that they finally made it useful again, I’m happy with it.
A few example searches to get the hang of the URL syntax:
News sources:
- [WayBack] Kristian Köhntopp – Google+: I would not have thought it possible, but after just several years of user feedback Google actually unfucked the search. It’s almost as awesome as their adblocker – absolutely essential, but too little, too late.
- [WayBack] Jaana Nyström – Google+: WOOHOOOOOO! The Classic Google+ style search is back! Now one can again search their own posts, even hashtag search works better. Top post vs. latest function, too. ❤️
- [WayBack] Roderick Gadellaa – Google+: #thatsaplus
- [WayBack] Anna Kiyantseva – Google+: …we’re rolling out a bevy of improvements to G+ Search — most visibly, you’ll find that typing into the search bar no longer interrupts your search attempts by taking you to Explore. That means that your results get to you that much faster!That’s not all…
- A new, tabbed interface will make it easier for you to find the exact type of content that you’re looking for.
- In the posts tab, you can filter based on the post author. Finally, you can look back at your many years of G+ posting without being distracted by everyone else’s Neko Atsume updates!
- Popular Topics are now displayed in the search bar dropdown.As always, let us know what you think and we hope you enjoy!

Edit 20260424: Cisco images via Wayback Machine as some of the links had died. Added some extra notes.
Note to self: looking at the various patch cables, it looks like most manufacturers prefer T568B over T568A. Not sure why. I adopted T568B to avoid any confusion.
As I always forget the images on FTP/STP/UTP wiring in both connectors and outlets and forget which standard is T568A and T568B: T568A and T568B termination – TIA/EIA-568 – Wikipedia:

The first method I try for any Apple TV issue is to reset the device (Hold the Play & Menu button simultaneously on the remote for 6 seconds)
Source: [Wayback] Fix Apple TV No Sound Issue – AppleTV2
This usually works for me too and is easier/faster than fiddling with the solutions mentioned at Wayback: Apple TV: HDMI audio stops working – Apple Support (which now has moved to [Wayback] Get help with audio, video, or power on Apple TV – Apple Support).
After releasing Play&Menu buttons, wait for the Apple TV to reboot itself and listen if your remote-buttons will give you audio-feedback from the Apple TV. If that works, then audio on multi-media works fine too.
This is way cheaper than putting additional hardware in the HDMI chain as described in [Wayback] The fix for AppleTV HDMI audio and video woes and HDMI problem solving | The Poor Audiophile
In my setup the [Wayback] Apple TV 3rd generation is hooked up to a [Wayback] Harman Kardon BDS 580 receiver/blue-ray-player.

Uptime robot (free for 50 monitors every 5 minutes) is cool:

These are xs4all fiber connections in Amsterdam and Sassenheim. Despite not mentioned on the xs4all status page [WayBack] XS4ALL | Storingen en werkzaamheden, apparently there was some fiber down time in both places.
The HeldenVanNu fiber connection in Amsterdam was doing fine at that time; those downtimes below were planned on my side:

testssl.sh has supported IPv6 for a long while if the OpenSSL binary supports it
See the below thread, specifically the mentioned comments.
- IPv6 · Issue #11 · drwetter/testssl.sh [WayBack]
- OpenSSL with IPv6 support is needed:
- You need to specify the
-6 parameter or have HAVE_IPv6=true set in HAS_IPv6=true testssl.sh <mycmdline>:
- Special branch of OpenSSL supporting all ciphers (reminder to self: build OS X binaries for it)
- Works with the Google IPv6 site:
- There is still some work to do:
- But the
--ip parameter now supports IPv6 addresses:

I could not find many potential anti-virus and -malware tools for OpenSuSE Tumbleweed despite they would be useful not only for non-Linux clients like Windows and Mac OS X.
These I found:
