Some issues with non-free firmware blobs on Debian
ASpeed Technologies
The sudo dmseg command shows the warning Possible missing firmware /lib/firmware/ast_dp501_fw.bin for module ast. This relates to the ASpeed BMS VGA graphics microcode.

Manjaro Setup Notes
I tried Manjaro circa 2019 for a couple of years as my main Linux Desktop. I had no major problems with it. An occasional minor problem this nVidia graphic card and some minor issues with updates. Having used Debian / Ubuntu the past 10 years on servers I decided to switch to Debian testing desk top with XFCE. Debian testing basically give a similar level of latest updates as Manjaro/Arch.

These are my rsync notes. I also used to use rsnapshot, however I was unhappy with the performance of this application and moved to restic. The original rsnapshot notes have been rolled up and moved to the bottom of this page.

Network Setup
Most server have more than one network connection although one is technically enough. Routers by definition need to have a minimum of at least 2 network connections.

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.
