exporting firewall config – MikroTik RouterOS

Posted by jpluimers on 2017/08/28

Example:

/ip firewall filter export file=ip-firewall-filter.rsc

This exports the Filters parts of the IP Firewall into a file named ip-firewall-filter.rsc in the user-space root of the Mikrotik router file system that you can access through the Files menu entry in WinBox or by external access through FTP or SFTP (SSH File Transfer Protocol).

Running your Mac Mini headless by faking a display for it (HDMI 1080p/4K or Thunderbolt VGA); similar for DVI

Posted by jpluimers on 2017/08/28

CompuLab 4K Display Emulator (fit-Headless 4K)

CompuLab 4K Display Emulator (fit-Headless 4K)

The MacMini is a bit dumb as it won’t enable the GPU when there is no display attached. Which means headless operation is cumbersome as display rendering is very slow.

There are a few tricks of which the off-the-shelve HDMI solutions work best.

You can buy them at Amazon:

Basically the trick to simulate a monitor with a dummy load works for other display connectors as well (most of them work fine with 75 ohm resistors, usually a bit lower or higher works just as well):

Performance Test WCF/WPF app – Selecting right Tool

Posted by jpluimers on 2017/08/26

Interesting read, especially because they did an extensive tool selection process. Not really up to date any more but a good start when you are looking for tools.

Amsterdam, 2.4 GHz. 5 GHz is only marginally better. In the city, wired connection is the only option: fiber, cable, dsl.

Posted by jpluimers on 2017/08/25

For me, too often – even at home – mobile internet is faster than WiFi over 2.4 Ghz and sometimes even faster than WiFi at 5 Ghz..

Further below is inside my home. I’ve no idea what these – relatively strong – networks are:

  • SANDS Wi-Fi Network (it has a MAC in the OUI list of Apple and is configured as GB device)
  • venus-HQ17128EGKE-5ae (it has a MAC in the local private range)
  • H368N8D6382 (and a network HZN242961585 that looks similar but is very different – the first has a MAC from ZTE corporation, the last from Samsung Electronics)

If you’re in Delphi land, then Asbjørn Heid is a a guy to follow on G+.

He has some brilliant snippets (most can be found on paste.ie by searching for Asbjørn Delphi site:paste.ie).

This is actually one set:

Some notes on making pi-hole work on a DHCP enabled network

Posted by jpluimers on 2017/08/24

Many networks have DHCP Manual allocation (commonly called static allocation) handing out static/fixed IP addresses over DHCP so you can centralise IP address handout based on MAC (or other attributes).

Here are some links that should me get going making my pi-hole Raspberry Pi using DHCP instead of static IP addresses.

Yucky way to set a static IP: How do I set a static IP address in Raspbian “Jessie” using /etc/dhcpcd.conf? – Pi-Hole: A Black Hole For Internet Advertisements [WayBack]

Designing your way out of the CanHandle-Handle conundrum | Software on a String

I recently had to refactor exactly this: Designing your way out of the CanHandle-Handle conundrum | Software on a String [WayBack] so I was glad that Marjan Veenema paved the path in 2015 for me.

Repurposing Old Smartphones for Home Automation | Linux.com | The source for Linux information

Posted by jpluimers on 2017/08/23

At the recent Embedded Linux Conference and OpenIoT Summit, Mozilla Technical Evangelist Dietrich Ayala proposed a simple and affordable solution to home automation: A discarded smartphone can handle some of the most useful home automation tasks without requiring expensive hubs and sensors — or risking data security in the cloud.

I’ve been awaiting talks like this for years basically because I didn’t take the time to try myself.
