Mikrotik RouterOS /ip firewall address-list timeout values sort-of documented
Posted by jpluimers on 2017/07/05
Thanks to ZeroByte answering at [Answered] Where are ip firewall address-list timeout values documented – MikroTik RouterOS [WayBack] which I edited a bit here:
I haven’t seen anything specific to the format of these time tokens, but the firewall add-to-address-list timeout is documented here:
http://wiki.mikrotik.com/wiki/Manual:IP … Properties…It seems to take the same format as any other similar duration-related input I’ve encountered:
- a raw number is interpreted as seconds
You can specify a number as another duration with tokens:
- s = seconds (default)
- m = minutes
- h = hours
- d = days
- w = weeks
A few aspects:
- Tokens can combine be in any order
- Whitespace is ignored
So these are all valid:
2s 2h 2w
1w2d3h4m5s
5s4m3h2d1w
- Days and weeks just get added together. If you specify 1w8d, this is the same as 2w1d
- The last value specified may be in h:m:s format or in h:m (omit seconds)
- Interestingly, if you mix and match, they just get added:
- “1d 2h 12:30” -> “1d 14:30:00”
- Values larger than 536870911 seconds are stored and tracked but when displayed show as 0sec.
(248 days, 13:13:55)- The maximum value is 4294967295 seconds (which is the maximum 32-bit value)
This decodes to: 7101w3d6h28m15s as the largest value….
(7101 weeks is ~136 years counting for leap years, by the way)

It’s from a while ago, but they’ve likely updated the supported motherboards and storage by now.

Tunneling over WebSockets
Posted by jpluimers on 2017/07/04
Just found out about these interesting links I had loved to use years ago, but alas, now I know (:
- How HTML5 Web Sockets Interact With Proxy Servers
- Vpn-ws – A VPN system over websockets | Hacker News
It looks similar to SSL VPN sometimes also called WebVPN:
Then there are non-VPN tunnels through WebSockets:
- covertcodes/multitun: Tunnel arbitrary traffic through an innocuous WebSocket. Clients can ‘see’ each other, resulting in a stealth WebSocket VPN.
- mhzed/wstunnel: tunnel over websocket
Since WebSockets can run over a proxy server you could route any kind of binary traffic through them even in places that disallow non-web protocols or layer-7 inspect https traffic.
Although ops might restrict stuff even further:
- firewalls – How does a network admin block the reverse SSH in company? – Information Security Stack Exchange
- SSH across a Layer 7 Filter · System Overlord

It’s such an all time classic from 2006 that people even kept scans of the original 2006 Computer World publication by [WayBack] John Klossner.
Over the last few years, it has done its round over the internet a few times, so I did some digging for the scans, colour and mono originals.
Data security versus Human Error.
In this corner, we have firewalls, encryption, antivirus software, etc. And in this corner, we have Dave!!
[WayBack] John Klossner Cartoons: Computer World has the original black and white version: it’s even a gif!
Way better than the scan from paper: [WayBack] ShackF00 » Weekend Round-up: Google Issues and a Sad-but-True Comic
In 2014, Spiceworks re-ran the black and white one: [WayBack] And in THIS corner we have Dave! (Funny cartoon) – IT Security – Spiceworks
In 2015, Wombat Security published a coloured version on social media, and even bigger too: not just large, huge as well (:

Some notes on Google Nest before getting it to control a Remeha Avanta 35c modulating heater
Posted by jpluimers on 2017/06/30
For my own reference:
- It looks like the Nest needs to communicate wirelessly with the Heatlink in order to support OpenTherm. I can’t find what frequency or protocol the Nest/Heatlink connection uses.
- Nest Thermostaat Topic – Duurzame Energie & Domotica – GoT
- Nest Thermostaat Topic – Duurzame Energie & Domotica – GoT – filter Avanta

But lots of people still report overshoots in temperatures. - Nest Learning Thermostat V3 – Prijzen – Tweakers
- Wat is de Heat Link?
- Hoe communiceren de Heat Link en de Nest Thermostat met elkaar?
- Nest Introduces Nest Weave, Creating Most Comprehensive Developer Platform for the Home | Nest
- Nest devices interconnect with each other using a protocol called Weave, which is based on IEEE 802.15.4 and Wi-Fi 802.11 b/g/n.[30] which seems to indicate it operates mostly on 2.4Ghz (which is distorted when neighbours use their Microwave to heat food).

David Hill – of ThinkPad design fame – is going beyond “Black Paint” – via: Rewiring | Lenovo
Posted by jpluimers on 2017/06/29
David Hill – of ThinkPad design fame – is going beyond “Black Paint”. It means he will be far less involved with [WayBack] ThinkPad: Industrial design, more with other design and – very important – his loved ones.
Today I’m announcing my “rewiring”. I want to broaden my view and create the opportunity to do more in the field of design.
