Much copied from Adam Sweet's wiki on IPMI.
What is IPMI?
IPMI is standard which allows remote server management, primarily developed by Intel. IPMI cards, known as Baseboard Management Cards (BMCs) are primitive computers in their own right and are operational all the time, so long as the server has a power source. The server itself does not need to be powered on, or the operating system operational for the BMC to work, it just needs a power source…text/html2025-01-03T00:55:46+00:00Anonymous (anonymous@undisclosed.example.com)Back-up Server Old Setup

Back-up Server Old Setup
This has been more difficult than I would have thought. I have used rsnapshot the past couple of years (2020-21), but have never really been happy with it for many reasons. The main reason is that it has never worked well, the rsync is reasonably fast, but the rsnapshot takes far too long. Other problems include; difficulties in set-up, and concerns will reliability. Recently I noticed that Debian no longer …text/html2025-05-18T07:27:42+00:00Anonymous (anonymous@undisclosed.example.com)IPMI Console Setup

IPMI Console Setup
I have 3 computers from Supermicro with BMC and IPMI. The Supermicro provided utility program IPMIView is good, but the iKVM console redirection facility is woefully unreliable and also seems to be poorly documented! (Probably because it is based upon Java.) Interestingly this utility program is provided for Windows and Linux, and is even available in Manjaro AUR repositories.

Set Up and Ubuntu APT Cache
The apt-cacher-ng looks to be a self container apt caching server. Basically the apt cacher stores all the relevant apt update and upgrade related files and and acts as a proxy server to multiple clients. A handy feature to improve speed and reduce Internet bandwidth where a virtual machine server is used with multiple clients. There is another package called apt-cacher but it depends upon th…text/html2023-11-19T02:47:59+00:00Anonymous (anonymous@undisclosed.example.com)SWAP Files

SWAP Files
As I have a computer with enough memory I see no need or value in a SWAP partition. In fact as I am using a SSD for the system drive a SWAP is a concern to the reliability of his drive.

Webmin
I don't bother to use Webmin, it has been well over a year since I tried to use.
Old, tl;dr;
I am a bit lazy sometimes and use Webmin to help setup certain services, e.g. Samba. Webmin is a web interfaced system administration system for Linux and has lots of plugins for various Linux apps/packages. Webmin has its own mini webserver built in. There are lots of web page discussing Webmin, how to install and use, e.g.text/html2023-05-13T02:20:29+00:00Anonymous (anonymous@undisclosed.example.com)NUT (Network UPS Tools) Setup
