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…

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.

Some links that were useful getting the SMS sending stuff to work.
The documentation is clear on what to do to send/receive SMS:
But it is unclear what USB hardware does work, so here are some links:
You can also do it the other way around:

Though the Mikrotik people seem reluctant to make the font size in Winbox configurable, if you run it through WineBottler on OS X, you can scale the individual app. It’s not very pretty but makes it easier to use.
The trick is based on the Windows DPI font settings explained for instance at DPI Display Size Settings – Change – Windows 7 Help Forums and Large Fonts in Registry: Where Exactly? | PC Review but then in Wine.
For Windows, this is a system wide setting, but on a WineBottler application there is one “Windows environment” per application, so it’s application specific and should work for other applications than WinBox as well.
It makes it much easier to do script editing now.
Steps I performed:

I’ve not tracked down the cause yet, but these seem to be related:
- The Mac OS X build of Atom IO
- WinBox v 3.4 WineBottle version from Winbox for Mac in an embedded Wine environment – Joshaven.com
- pbcopy / pbpaste that allow command-line copy/pasting
- none of these being able to copy/paste any more and return error level 1 like terminal – pbcopy exits code 1, no error message – Ask Different but not even running tmux or screen which means this solution does not apply: ChrisJohnsen/tmux-MacOSX-pasteboard: Notes and workarounds for accessing the Mac OS X pasteboard in tmux sessions.
- I didn’t have Mouse Keys turned on
- Other applications (Chrome, FireFox, TextEdit, Finder, etc) still being able to copy/paste between each other
I’ve “fixed” 4. by doing this as recommended at osx – Copy and Cut sometimes don’t work – Ask Different:

Earlier, I wrote “:for loops are a strange beast so I will elaborate on those in a separate post.” so now is the time to do that.
The :for loop documentation is very dense:
| Command |
Syntax |
Description |
| for |
:for <var> from=<int> to=<int> step=<int> do={ <commands> } |
execute commands over a given number of iterations |
So a for loop has these elements:
Luckily, the old RouterOS 2.7 documentation on loops (which they’ve revamped after Router OS 2.7 removing many useful examples) has this:
:for – It has one unnamed argument, the name of the loop variable. from argument is the starting value for the loop counter, tovalue is the final value. This command counts loop variable up or down starting at from and ending with to, inclusive, and for each value it executes the do statement. It is possible to change the increment from the default 1 (or -1), by specifying the stepargument.
[admin@MikroTik] > :for i from=1 to=100 step=37 do={:put ($i . " - " . 1000/$i)}
1 - 1000
38 - 26
75 - 13
[admin@MikroTik] >
You might think that from= the start value, to= the finish value and the loop won’t execute when step= a positive value and from= larger than to=. Or that without a step= the loop will always iterate in ascending order.
Wrong! And wrong!
So it’s time for some…

If it had function keys, I might have ordered it, but in case anyone is still interested: order before the end of July as they will likely not do a re-run of this unique project: [Archive.is] Brand New Model F Keyboards – The Model M Predecessor: Mechanical Capacitive Buckling Spring Keyboards with NKRO.
Model F quality is much better than Model M, which is way better than anything manufactured after that. Just compare the spring mechanisms below.

TomatoUSB recommends a NVRAM reset (or 30/30/30 reset) before and after upgrades.
This means you loose all your settings which causes a lot of people to not upgrade at all.
The steps to export/import are a bit vague as they depend on what you want to save.
It basically comes down to do this on the old configuration
nvram export --set
Save that output to a local file and then use a search tool searching for specific sections you want to restore.
After you restored the sections ensure you persist them:
nvram commit
This is what the TomatoUSB author usually searches for:
