Server chronical - Digitemp - reading from DS1490F

Digitemp is a software capable to read Dallas 1Wire sensors for the temperature, the DS18S20.

It was in use on the old server for years in order to acquire different temperatures and thus control automatically some Fans in the server room.

Let's see if it can be revived in the new server.

Server chronicles - Drobo on ProLiant

 On the old server I used a USB Drobo unit to backup data.

In theory should be enough to connect the unit to the server to see it .. and in part is true, but there are some unexpected problems.

Updating the Ender 3 Pro - the controller

 

After 1 year of playing with the 3D printer Ender 3 Pro I decided to do some upgrades.

Changing the controller to improve accuracy, speed and noise, changing the display to better locally control some options and add the BLTouch, to simplify the leveling.

This article is about changing the controller and the TFT display

Ubuntu - media, from iso to mp4/mkv

This is a brief note to describe how to solve a problem.

After reinstalling my media server I decided to do some spring cleaning.

I did find many movies I did record years ago and created as iso image.

In this way unfortunately is not easy to see them directly on Plex, the best way is to convert them in mp4 (or mkv).

Server chronicles - Plex on ProLiant

 One of the goals I want to achieve rebuilding the server is to reinstall services in a better way.

One of the services is my Plex server

PiKVM - a KVM <-> IP on System76

Is always better to have a Plan B if the main plan fails.
My server has an embedded KVM (with an extra module installed - see the article Fixing the server - KVM <-> IP) but surprise surprise the actual KVM functionality is not working because the motherboard is not supporting an extension module.

This article discuss about the KVM <-> IP solution with a Raspberry Pi on the open source project PiKVM as a way to have the KVM functionality on my server.

Server chronicles - fan noise problem on System76

 The server has 3 high speed industrial grade fan to keep it cool.

They are great but are quite noisy.

More understanding about how to control them is needed.

Server chronicles - Docker on ProLiant

At the base of the rebuilding of the services on the server, there is Docker.

Docker allows to run services in a dedicated environment.
Why ? Well, because different applications/programs can require different settings, like maybe the installation of specific languages or specific versions of them.
Instead to clutter the server with 3000 things, a docker image is totally self sufficient.

Server chronicles - KVM <-> IP on old System76

One of the things I would like to have in the renewed server is the capability to remote access it for monitor or emergency repairs or, like now, for a rebuilding, without the need to be physically present in the "server room" (in my case the garage) to connect a keyboard and monitor to the console.
This article is about the introduction and hardware settings, another one will discuss the installation and use.

Server chronicles - the OS on the old System76

The old System76 server has now new HDs and more RAM and is cleaned up.

Time to install the OS.
