For now, a small utility that allows to sync data between multiple computers over the network, using Unison.
Pre-requisite:
- computers with ssh ports open -- port 46 is for now default
- nmap installed on running machine
- unison installed on all machines
- a config file for now stored in
~/.bin/backup_hosts/hostlist
The config file is filled manually and contains the signature of each device, as well as which folders to sync for each. The folder lines are indicated with a star, and having a single name means the same path is used for both machines. An example file syncing cheatsheets with 2 machines would look like:
ED25519 SHA256:******************************************* MachineName1 vogu
* Cheats /home/vogu/.config/cheat/cheatsheets/personal
RSA SHA256:******************************************* MachineName2 UserName2
* Cheats /home/vogu/.config/cheat/cheatsheets/personal /home/UserName2/.config/cheat/cheatsheets/personal
Then, based on the config file, the utility checks which known hosts are connected on the network, then syncs all possible files twice in a star configuration to ensure all files are up to date on all machines.
Nmap is used to check network availability, so using this on a public network is kinda rude.
It's a bit messy, and is far from following all good practices, and should probably be split, organised, and a bunch of features should be added. It's just a minimum viable product to answer my most basic needs for now. But it works.
