Refactoring latent / blueprints

[skrupler]

Hook, line and sinker

Current latent version suffers from alot of bugs thus I am going to refactor it and add some useful things to better handle crashes and hickups without having to reboot the entire machine to "get it right".

To be implemented

• helpers/setup.sh - basic setup, takes user input if settings.conf is missing any arguments
• check dependencies
• get user information if any critical ones are missing from conf/settings.conf (saves stuff too)
• helpers/functions.sh - global functions needed by this suite
• check the ip which rtorrent is bound to
• check the actual ip on the tun/tap device
• src/netns.sh - handles the setup of the network namespace
• setup/tare down of netns
• src/openvpn.sh - handles the connection of openvpn
• src/rtorrent.sh - handles startup/shutdown etc
• handles the connection, doesnt really do much but for sake of separation
• latent.sh - one script to rule em all, aka the runnable one
• probably the one callable we feed to systemd or whatever
• cron/example.cron
• calls the helpers/functions.sh to check if mismatch with ip and restarts rtorrent if true.

• checking if IP changes as per Handle situation when ip changes on the vpn connection #2

Fixes

• check permissions on critical files
• chmod 600 auth.txt
