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)

More beautiful code by Asbjørn Heid
Posted by jpluimers on 2017/08/25
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:
- Working code: Tuple duple – Paste.ie – Irish For Pastebin [WayBack]
- Concept (not actual working code): Channeling – Paste.ie – Irish For Pastebin [WayBack]
Both via From the because-I-can department… Friday evening operator abuse. Tuple Duple [WayBack]
Then there are these:
- Checkpoint logging [WayBack]: log only stuff when there is an exception based on Superior logging design – Fast but comprehensive – CodeProject [WayBack] via I’m wondering if the “checkpoint” feature could be implemented with Delphi. Basically, it allows to log only when needed… – Agustin Ortu – Google+

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.
- Chapter 5. Network setup – hostname resolution
- Raspberry Pi • View topic – Configuring Network using dhcpcd
- dhcpcd – ArchWiki
- raspbian – dhcpcd vs /etc/network/interfaces – Raspberry Pi Stack Exchange
- NetworkConfiguration: DHCP – Debian Wiki
- NetworkConfiguration – Debian Wiki
- Raspberry Pi • View topic – How to find the current IP address?
- server – How do I show active dhcp leases – Ask Ubuntu
- DHCP table in Debian – Super User
- Work with DHCP address instead of static IP address configuration. · Issue #629 · pi-hole/pi-hole

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.

Manual:CRS examples – MikroTik Wiki
Posted by jpluimers on 2017/08/22
The Cloud Router Switches support three types of mirroring. Port based mirroring can be applied to any of switch-chip ports, VLAN based mirroring works for all specified VLANs regardless switch-chip ports and MAC based mirroring copies traffic sent or received from specific device reachable from the port configured in Unicast Forwarding Database.
Port Based Mirroring
The first configuration sets ether5 port as a mirror0 analyzer port for both ingress and egress mirroring, mirrored traffic will be sent to this port. Port based ingress and egress mirroring is enabled from ether6 port.
/interface ethernet switch set ingress-mirror0=ether5 egress-mirror0=ether5 /interface ethernet switch port set ether6 ingress-mirror-to=mirror0 egress-mirror-to=mirror0
Source: Manual:CRS examples – MikroTik Wiki [WayBack]
This allows you to torch traffic from a specific port despite that port being grouped to a master-port.
Via: Torch not working with CRS226-24G-2S+ – MikroTik RouterOS [WayBack]
But, when using Bridge, all ports share a single 1 gbps link to the CPU, so your layer 2 performance will suffer horribly.
If you need to see all the traffic from a single port when using Master/slave port configuration, use port mirroring.

MAC-Telnet: Open source MAC Telnet client and server for connecting to Microtik RouterOS routers and Posix machines via MAC address.
Posted by jpluimers on 2017/08/22
Found out about this a while ago:
MAC-Telnet – Open source MAC Telnet client and server for connecting to Microtik RouterOS routers and Posix machines via MAC address.
Source: haakonnessjoen/MAC-Telnet: Open source MAC Telnet client and server for connecting to Microtik RouterOS routers and Posix machines via MAC address. [Fork]
Background:
Earlier, I wrote about a Wireshark plugin for dissecting Mac-Telnet packets. Now I have created an open source application for connecting to a RouterOS router.
