    At this weekend I finally established another network in my home — a ZigBee network. A looong time ago (in 2010 year) I touched the ZigBee networking in my university (ITMO, previously IFMO, in Saint-Petersburg) — these times it was a new technology, not used widely. And as a student I have some fun time playing with ZigBee main router, supplemental router and end-devices. You can view old photos and screenshots of old software on a my extremely old blog: http://h0rr0rr-drag0n.blogspot.com/2010/04/cc2530zdk.html (and read a blogpost, if you understand Russian).It is kindly fascinating, that now, after 15 years, I can just buy some ZigBee-powered devices from AliExpress (using Black Friday discounts) and connect them to the network inside my house right in the way I did it in the university 15 years ago!Sadly, although I bought native supported main router device, based on the EFR32MG2 with some software from Ember (EZSP v8) inside, the OpenHAB doesn't support this device natively — it supports it, but since my server is running NetBSD, I got problems with some bundled with OpenHAB things. Looks like some native libraries (rxtx-java) don't have bundled NetBSD versions. And the same library in the repository built for Java 8, not for Java 17.So, I decided to use Zigbee2MQTT, not to build the necessary Java library myself. It was kinda scary — use program, which connects my ZigBee network via ZigBee USB-dongle to the MQTT server — which is written on JavaScript . Not on the C (as I can totally understand, for a such low-level program, operating with embedded devices) or at least on the C++/Perl/Python/whatever. But, looks like it works good enough, if I don't try to pair the device in wrong mode (my window sensors has two modes to pair them with network: first "common" mode causes zigbee2mqtt to silently crash and the second "compatible" mode works without problems).And I could understand now, why people has so much problems with smart home security. Installed MQTT server mosquitto — it allows unauthenticated connections by default. Installed zigbee2mqtt — it allow connections to frontend without any password by default At least these two services don't each much memory: 1.2 Mb for Mosquitto and 75.6 Mb for ZigBee2MQTT.For now, my ZigBee sensors works pretty well and robust, like these devices from university 15 years ago #HomeAutomation #OpenHAB #ZigBee #HomeLab

    @stefano Running Leap 16 in VirtualBox 7.1 on my Debian laptop. Leap 16 has some problems.First, it only successfully boots every *other* time it powers on. The other times, after the boot loader, it shuts down automatically with no warning.Secondly, there are strange network issues though this may be a Virtual Box thing. I just tried installing Debian 13 and the network config during the installer is continuously failing at DHCP. I'm on public wifi at a hospital, but that shouldn't matter because the laptop itself and my phone connect to the wifi no problems. I suspect I have some troubleshooting to do there....but only being able to successfully power up every other time? Yeah, that is strange.

    Mentre tento di scrivere un articolo introduttivo su Git, sto sperimentando con Proxmox.La scalabilità del progetto è impressionante. Già in un piccolo homelab si possono semplificare operazioni complesse, per non parlare dei grandi datacenter.I container di Alpine Linux poi, con tanto di OpenRC in esecuzione, sono amorevoli.Una volta acquisita un po' più di consapevolezza in merito, ne riparleremo sicuramente!@linux #linux #unolinux #gnulinuxitalia #opensource #homelab #proxmox #git
