I want to build a processing center at home using the Raspberry PI as its hardware base.
Ordered 3 Raspberry Pi 4 with PoE Hats and a 16 port unmanaged bridge to start. Working on getting Clonezilla on development machine.Web References https://johnnywunder.info/mywiki/index.php/Home Computer Center

Log
- --Johnny 10:13, 25 October 2020 (EDT) Have Conn and Buffalo NAS set-up but struggling with [http:/www Webserver]. There was a major SQL upgrade going from 5.7 to 8.0 which has left MySQL Workbench not working and forced and upgrade of Semantic Mediawiki and all the attendant database issues. Focused on the AppArmor MySQL Workbench incompatibility right not. See Problems below.
- --Johnny 19:38, 25 September 2020 (EDT) Ordered and built hardware wise first Raspberry Pi with POE. Having trouble getting OS installed and bootable. Did a Raspian Lite and it worked and now doing Raspian Full. Was unable to use Raspberry Pi Imager and need to find out why?
- --Johnny 00:31, 8 October 2020 (EDT) Buffalo Link Station 220 showed up. Took 2 days to get mounted omn Linux. Key was to use cifs vers=1.0 in mount command and fstab. Looks to be working now.
sudo mount -t cifs -o username=,password=,vers=1.0 //192.168.N.N/share /mnt/share --verbose
Problems
- --Johnny (talk) 08:27, 26 February 2021 (EST) Squid cannot handle https as distributed by Debian. has right architecture ARMF squid-openssl but has unmet dependencies. Waiting on upgrade.

sudo snap connect mysql-workbench-community:password-manager-service :password-manager-service
took us one step closer allowing me to store password in Gnome.
Suspect next issue is to address the MySQL password changes with the upgrade to 8 partucularly the sha-256 caching of passwords.
Deleted and re-added key user with default options and workbench started working. Need to remember users are tied to hosts.
