playing with IOT

Posted by jpluimers on 2018/09/06

Interesting stuff:

Open-source home automation platform running on Python 3. Track and control all devices at home and automate control. Installation in less than a minute.

Ik doe dus een hoop met home-assistant (https://home-assistant.io/) en wat custom Python scripts/apis wat allemaal op een oude laptop met ubuntu draait (10w verbruik).

De Horizon Box specifiek gaat via Harmony Hub, kan via de standaard integratie of via eigen brouwsels. Lifx en Nest heeft standaard integratie met Google Home. Al heb ik voor Lifx zelf het een-en-ander geschreven in Python om bijvoorbeeld scenes op te slaan en op te roepen met voice commando’s, dat kan weer niet standaard. NS API gaat ook via die Python API en wat er terug gezegd wordt (in het Nederlands) gaat via home-assistant.

Het voordeel van zelf zoiets bouwen is dat ik alles makkelijkers aan elkaar kan knopen dan bijvoorbeeld via IFTTT en Stringify o.i.d.. Zo kan ik bijvoorbeeld “Hey Google, sexy time” roepen en dan veranderd mijn verlichting langzaam naar iets romantischers (denk rood/oranje/roze), speelt er een zwoel lounge muziekje op mijn Sonos van een samba share, gaat de tempratuur wat omhoog en gaat mijn tv aan naar het chromecast kanaal en speelt er van die zelfde samba share een mp4 met een haardvuurtje.

Vet cheesy, I know, ik moet er de eerste vrouw nog mee verrassen :P maar het was ook vooral als demo van wat ik allemaal kan aansturen, bedoeld als grapje voor vrienden etc.

Google voegt een notificatiefunctie toe aan zijn Home-speaker. Als gebruikers een belangrijk bericht krijgen, zullen de ledjes op de speaker de aandacht gaan trekken van de gebruiker. De speaker gaat vooralsnog niet uit zichzelf spreken.

Going to test some USB 3 gigabit ethernet adapters based on Realtek RTL8153 and Asix AX88179 chips

Posted by jpluimers on 2018/07/27

Later on, I might add a USB31000S in the mix, but I will do some initial testing with USB 3 gigabit ethernet adapters based on Realtek RTL8153 and Asix AX88179 chips.

Things I will focus on with my Retina MacBook Pro 2015 model are:

  • CPU usage
  • Throughput
  • Duration between reconnect on USB after suspend, and renewing the DHCP lease
  • Promiscuous mode capabilities

Some links for my references:

A first impression from the above links is that for Realtek chipset based devices, drivers are more readily included in operating systems, and these chipsets are better at VLAN handling.

In case I ever need to record calls on my Fritz!Box devices

Posted by jpluimers on 2018/07/23

I need to dig a bit deeper into these links to see how easy it is to record calls made on a Fritz!Box then playing back the captured calls.

Note that in various countries you have to indicate to the calling parties that their calls can be recorded.

How I made my own VPN server in 15 minutes | TechCrunch

Posted by jpluimers on 2018/07/13

People are (rightfully) freaking out about their privacy as the Senate voted to let internet providers share your private data with advertisers. While it’s important to protect your privacy,…

Interesting: easy setup allows for creating disposable VPN servers.

Skype consumer IP ranges

Posted by jpluimers on 2018/07/09

Since I will likely have to enable Skype in a relatively restricted environment, here are some links that likely will help me getting IP lists to open up:

Just in case I move away from Mikrotik

Posted by jpluimers on 2018/07/02

Mikrotik has great hardware, great firmware (if you have the right builds), but notoriously bad documentation and a not so great software release and testing process.

So I might consider switching away, so here are some threats that might lead to alternatives:

I use ubnt edgerouters, great bang for buck. My ER Pro-8 has been up for 8 months (no reboots) and hasn’t missed a beat, rock solid ipsec vpn. I looked at microtik, but found the edgerouters slightly easier to configure.

Urgent security advisory – MikroTik – upgrade to 6.41.3 if you can change your bridge implementation, ensure SMB and WWW are not WAN accessible

Posted by jpluimers on 2018/03/31

I both understand the [WayBack] Urgent security advisory – MikroTik and the users reluctant to upgrade: Mikrotik has a history of updates breaking existing behaviour and underdocumenting features and release notes.

The attack is over the www or www-ssl services which by default run on port 80 and 443. You can see on which networks they are bound using this example from the terminal:
