Region Selection and Other Improvements

Browse Source 
- separated get_region and get_token into two separate scripts, allowing for independent calls to each if desired; this also allows the implementation of other features mentioned below
- implemented use of new centralized authentication server for easier automation; the new API is  located at https://privateinternetaccess.com/gtoken/generateToken
- added server selection capabilities to run_setup.sh, as requested by multiple users
- added one-line call capabilities to run_setup.sh to allow easy automation
- changed PIA_AUTOCONNECT to VPN_PROTOCOL for clarity
- added AUTOCONNECT for one-line calls
- added PREFERRED_REGION for one-line calls
- added colored output to highlight important details
- added input validation for prompts in run_setup.sh

The scripts were written so that they are easy to read and to modify. The code also has a lot of comments, so that you find all the information you might need. We hope you will enjoy forking the repo and customizing the scripts for your setup! The scripts were written so that they are easy to read and to modify.

In order to help you use VPN services and PF on any device, we have prepared a few bash scripts that should help you through the process of setting everything up. The scripts also contain a lot of comments, just in case you require detailed information regarding how the technology works. The functionality is controlled via environment variables, so that you have an easy time automating your setup. In order to help you use VPN services and PF on any device, we have prepared a few bash scripts that should help you through the process of setting everything up. The scripts also contain a lot of comments, just in case you require detailed information regarding how the technology works. The functionality is controlled via environment variables, so that you have an easy time automating your setup.
The easiest way to trigger a fully automated connection is by running this oneliner:
```
sudo VPN_PROTOCOL=wireguard DISABLE_IPV6="no" AUTOCONNECT=true PIA_PF=false PIA_USER=p0123456 PIA_PASS=xxxxxxxx ./run_setup.sh
```
Here is a list of scripts you could find useful: Here is a list of scripts you could find useful:
* [Get the best region and a token](get_region_and_token.sh): This script helps you to get the best region and also to get a token for VPN authentication. Adding your PIA credentials to env vars `PIA_USER` and `PIA_PASS` will allow the script to also get a VPN token. The script can also trigger the WireGuard script to create a connection, if you specify `PIA_AUTOCONNECT=wireguard` or `PIA_AUTOCONNECT=openvpn_udp_standard` * [Prompt based connection](run_setup.sh): This script allows connections with a one-line call, or will prompt for any missing or invalid variables. Varaibles available for one-line calls include:
* `PIA_USER` - your PIA username
* `PIA_PASS` - your PIA password
* `PIA_DNS` - true/false
* `PIA_PF` - true/false
* `MAX_LATENCY` - numeric value, in seconds
* `AUTOCONNECT` - true/false; this will test for and select the server with the lowest latency, it will overried PREFERRED_REGION
* `PREFERRED_REGION` - the region ID for a PIA server
* `VPN_PROTOCOL` - wireguard or openvpn; openvpn will default to openvpn_udp_standard, but can also specify openvpn_tcp/udp_standad/strong
* `DISABLE_IPV6` - yes/no
* [Get region details](get_region.sh): This script will provide server details, validate `PREFERRED_REGION` input, and can determine the lowest latency location. The script can also trigger VPN connections, if you specify `VPN_PROTOCOL=wireguard` or `VPN_PROTOCOL=openvpn`; doing so requires a token. This script can reference `get_token.sh` with use of `PIA_USER` and `PIA_PASS`. If called without specifying `PREFERRED_REGION` this script writes a list of servers within lower than `MAX_LATENCY` to a `/opt/piavpn-manual/latencyList` for reference.
* [Get a token](get_token.sh): This script allows you to get an authentication token with a valid 'PIA_USER' and 'PIA_PASS'. It will write the token and its expiration date to `/opt/piavpn-manual/token` for reference.
* [Connect to WireGuard](connect_to_wireguard_with_token.sh): This script allows you to connect to the VPN server via WireGuard. * [Connect to WireGuard](connect_to_wireguard_with_token.sh): This script allows you to connect to the VPN server via WireGuard.
* [Connect to OpenVPN](connect_to_openvpn_with_token.sh): This script allows you to connect to the VPN server via OpenVPN. * [Connect to OpenVPN](connect_to_openvpn_with_token.sh): This script allows you to connect to the VPN server via OpenVPN.
* [Enable Port Forwarding](port_forwarding.sh): Enables you to add Port Forwarding to an existing VPN connection. Adding the environment variable `PIA_PF=true` to any of the previous scripts will also trigger this script. * [Enable Port Forwarding](port_forwarding.sh): Enables you to add Port Forwarding to an existing VPN connection. Adding the environment variable `PIA_PF=true` to any of the previous scripts will also trigger this script.
