To handle restarts and failures more easily. Since netns rarely failes when rtorrent does for various reasons.
Should help mitigate and make for an easier fix for #2 aswell.

Currently the exit mode is horrible, needs fixing. Probably duplicates iptables rules if exit is not clean. The system needs to be restored to its state prior to execution.

Rtorrent stops working when bound to an IP not associated with the actual IP on the nic of netns.
This issue happens when the IP on the connection changes
but rtorrent tries to bind to the old IP
must be circumvented somehow.

Steps to reproduce:

1. run rtorrent on an openvpn connection for a while
2. wait for ip to change
3. error message appears: Error: Tracker: [Failed binding local connection end]

Solution

rtorrent probably needs to restart / rebind somehow.

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 #2

Fixes

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