technical Mapping sensors output to physical drives in Linux Whilst building out some new Grafana dashboards over the weekend I made the switch from InfluxDB to Promtheus node exporters for scraping metrics from Linux servers. But how do you marry up the drivetemp-scsi-0-10 value output from sensors to a physical disk?
technical Use 1 PiKVM instance to control 4 systems And there we have it. One PiKVM able to control and view up to 4 systems at once. And with the addition of a USB thumb drive to the KVM we can even boot any ISO we want!
technical Restricting ASRock Rack BMC to dedicated IPMI_LAN port only During this process I came across a frustrating "bug" in the Asrock Rack BMC implementation. No matter the settings I gave the BMC it was getting two IP addresses. One on the IPMI_LAN port as expected in my management VLAN, and another on eth0 which is undesirable.
ansible Check for duplicate items in a list with Ansible using a custom filter I expected writing a custom filter was going to be difficult and cumbersome but it was very simple and in the end, much faster than trying to turn YAML into a programming language!

docker Configuring Traefik on Synology DSM7 using docker macvlans Recent changes in DSM7 have made guaranteeing being able to free up ports 80/443 for use by traefik rather difficult. Using a combination of several advanced techniques with docker networking we can circumvent this requirement once and for all with the macvlan driver.
