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:

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.

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.

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.

bind “the working directory is not writable”

Posted by jpluimers on 2017/08/21

I didn’t notice this bind change for a while, but some time ago after doing an rcnamed restart it would split out this error message:

the working directory is not writable

It seems harmless as BIND still starts:

Starting name server BIND ..done

Anyway, some links that helped me solve it:

The last entry provides the solution:

rcnamed stop
chown named:named /var/lib/named/ -R
rcnamed start
rcnamed status

The latter didn’t show any error message.
