= Purpose = We would like to have a more convenient way to manage the door controller and keep track of who exactly has which badge === Goals === *Able to securely manage tags from local LAN *Menu driven UI (ncurses?) *Keeps track of when someone was added and which UID somebody has *You must present an admin tag at an Ackess door controller before any changes are applied. *Keeps a versioned backup of its CSV database on a network storage location === To be determined if in scope or not === *Log access times of space. (Do we need this? Do we want this? Privacy vs. access management debate. Would require a modification on Ackess 2.0 as it currently does not output this information) === Not in scope === *Manage system remotely from the internet *Open door remotely / without presenting a tag = Hardware = I've settled on using a Dell Wyse Cx0 C10LE thin client. Using a Raspberry Pi was considered, but it is more powerful than required and costs us money, while this donated Wyse device is sitting in storage and could really use a purpose in life. :-) === Specs === *CPU: Via C7 @ 1GHz *RAM: 256MB *Storage: 100MB '''(!)''' *Video: VX855/VX875 Chrome 9 HCM (Max resolution) 1920 x 1200 @ 60Hz Colour:15/16/24/32bpp) *Power: 12V 2.5A, Coax 5.5mm/2.1mm *Power usage: Off: 1W, Idle: 5W, Running: 7W Source: https://www.parkytowers.me.uk/thin/wyse/cx0/ (with a correction) = Operating system = Since we only have 100MB of storage to work with, the choises for an OS are limited. Yes I could have installed on an external USB flash drive, but where's the fun in that? :p After some research and looking around, I've settled on using SliTaz Linux. An installation without a GUI takes up a footprint of merely 25MB, which accomodates our main hardware bottleneck on the Wyse hardware. SliTaz homepage: https://www.slitaz.org/en/ SliTaz documentation: https://doc.slitaz.org/en:handbook:start SliTaz community documentation: https://slitaz-wiki.readthedocs.io/start.html === Installation and configuration === Exact steps for installation and configuration of the OS goes here = Software = *Will be written in plain C. Python was considered but the storage overhead of the Python packages was deemed too great. *Database will be a plain CSV file *Will have a menu driven UI using ncurses
