VMware FAH Appliance: Making Of F@H-Stats


You might have seen my previous blog post about the VMware Appliance for Folding@Home. This article is about how the local console was made underneath – and actually how simple it is.

Usually when powering on a Linux-based operating system, you just get the usual login console after boot. I thought that it would be handy to see what or if something is ongoing without actually logging in – so in other words: Seeing how busy the virtual machine is, and what the Folding@Home software is doing.

So I went ahead figuring out a simple, fast and easy way showing both. Ending up with the idea: Using a terminal multiplexer, and showing the classic top and tail -f /var/lib/fahclient/log.txt.

That’s how it looks like (when Enable F@H Stats in VM Console was enabled during deployment):

This is how it works…Read full article »

Horizon 7.10: Enabling dynamic codec switching


VMware Horizon 7.10 – released on September 17, 2019 – ships with a new dynamic encoder. Depending on what content you’re watching to in your VDI, it will seamless switch to the best suiting codec for optimal performance/quality-balance. While H.264 is ideal for rapidly changing contents like videos, JPG/PNG offers better quality for more static content like Office applications. Overall: Neat stuff!

As of this release the “switch”-Codec is disabled by default and must be explicitly enabled via registry. Also make sure you’re using Horizon Client 5.2 or later to make the codec work.

Log Insight: Change node IP address


vRLI Cluster Settings

How to change the IP address of a VMware vRealize Log Insight node? Glad you asked! I’ve done this change a few weeks earlier to be able to take use of the recommended “Integrated Load Balancer” (in short ILB) while re-using the existing node IP address for the Virtual IP address, mainly for backwards-compatibility reasons like already deployed agents.Read full article »

HPE Gen8: Redundant boot devices with FreeNAS


Since more than a year I’m running FreeNAS on a dedicated HPE ML310e v2 Gen8 machine in my HomeLab as my main storage, mainly as a iSCSI server for my VMware ESXi nodes. However when building this specific setup, I’ve came across a limitation from the BIOS: Just like the HPE MicroServer Gen8 the ML310e v2-tower is only able to boot from the first attached SATA device. So when the system disk is not detected as the first disk or once the first boot device fails (partially), the FreeNAS machine can’t boot up anymore. Not something I was pretty happy about, specially because FreeNAS runs on small mirrored SSD drives.

Time to get a workaround in place to get across this limitations. However one important aspect was to keep FreeNAS untouched, to prevent that something breaks after future updates. After a lot of research and hardware reboots I was able to come up with a working solution for me…

PowerShell für Linux und macOS


Interaktive PowerShell

Here it comes… PowerShell Core.

PowerShell auf Windows

Überraschung! Microsoft hat vor wenigen Tagen die von der Windows-Welt allbekannte PowerShell für Linux- und macOS Systeme öffentlich freigegeben. Und zwar steht nun das Projekt auf GitHub unter der MIT-Lizenz – also OpenSource – für jeden frei zur Verfügung. Es gab bereits vor einigen Wochen einige Spekulationen und mehrfache inoffizielle Aussagen, dass Microsofts Shell OpenSource auch für andere Systemen erscheinen soll. Diese haben sich hiermit nun bestätigt
