AIS receiver on a Raspberry Pi with RTL-SDR
The automatic identification system (AIS) is an automatic tracking system that uses transponders on ships and is used by vessel traffic services (VTS). AIS information supplements marine radar, which continues to be the primary method of collision avoidance for water transport.

Automation virtual commissioning : PLCSIM advanced 2.0 with C#
This is is a short demonstration of a co-simulation between Siemens PLCSIM Advanced and C#.
The goal is simple : have the ability to conditionally change inputs.
We’ll do a proof of concept with a small exemple for a safety relay monitored by a feedback.

Monitor a host from a Zabbix Agent (ping / ICMP)
Monitoring my Raspberry Pi network behind NAT is easy using OpenVPN and Zabbix agent/server.
In a few cases, I need to monitor hosts without any possibilities to install OpenVPN and Zabbix agent on it (switchs, routers, wemos, arduinos…).

Monitor a Raspberry Pi using Zabbix Agent on Raspbian
Once the server is ready, we can start to configure our agents.
Install the zabbix-agent :
|
1 |
sudo apt-get install zabbix-agent |
Edit the configuration file :
|
1 |
sudo vi /etc/zabbix/zabbix_agentd.conf |
