Setup Instructions for Sentinel Node hosting
===

Below are the steps involved in getting a Sentinel dVPN OpenVPN and SOCKS5 Node up and running.

0. Configuring firewall
1. Installing docker
2. Running the **Sentinel dVPN** docker image
3. Updating an existing Sentinel dVPN OpenVPN Node

## OpenVPN Sentinel Node

To run the Sentinel dVPN OpenVPN node, a user has to go through the following steps:

### Step 0 --- Configuring Firewall
---

Below are the instructions for configuring the firewall:

1. Firstly, open specific ports on the firewall, as required. Do not open all the ports.

2. UFW or Uncomplicated Firewall is installed by default on Ubuntu. If it has been uninstalled for some reason or needs an update, it can be installed with the following command:

`sudo apt-get install ufw`

3. Type the following command in the terminal to check the status of the firewall

`sudo ufw status verbose`

4. If the status of the firewall is `inactive`, then use the following command to activate it:

`sudo ufw enable`

5. For OpenVPN to work successfully, type the following command to allow the required ports through UFW

`sudo ufw allow 3000`
`sudo ufw allow 1194`

6. Refer to the following image for all the steps explained above.


### Step 1 --- Installing Docker
---

##### OS Requirements

* A 64-bit installation
* Version 3.10 or higher of the Linux kernel.

As the first step to setting Sentinel dPVN OpenVPN node on Linux, the user will need to install [Docker](https://www.docker.com/).

1. Update the apt package index:

`sudo apt-get update`

2. Install required dependencies to get the docker installation script located [here](https://get.docker.com).

`sudo apt-get install curl`

`curl -fsSL get.docker.com -o /tmp/get-docker.sh`

2. Run the downloaded script to setup & install docker

`sudo sh /tmp/get-docker.sh`

3. Add current user to the docker group to give required access

`sudo usermod -aG docker $USER`

### Step 2 --- Running the Sentinel dVPN OpenVPN Node
---

The VPN node can be set up and run in two ways:

1. Quick Run - by downloading docker image from Docker Hub.
2. DIY - by building a custom docker image from the Sentinel code repository.

#### Method #1 [Quick Run: Download Docker Image from Docker Hub]

Using existing docker image:

1. Navigate to the User's home directory.

`cd ~`

2. Create a new folder to pull the docker image and run it.

`mkdir -p $HOME/.sentinel`

3. Pull the official Sentinel docker image from Docker Hub & configure the node.

`sudo docker run -it --privileged --mount type=bind,source=$HOME/.sentinel,target=/root/.sentinel -p 3000:3000 -p 1194:1194/udp sentinelofficial/sentinel-vpn-node:0.0.8-alpha`

#### Method #2 [DIY: Build a Custom Docker Image]

Do-it-Yourself setup by building a custom docker image:

1. Navigate to the root folder or specifiy any other directory for the project and download code from the repository.

`cd ~`
2. Clone the Sentinel repository.

`git clone https://github.com/sentinel-official/sentinel.git`

3. Navigate into the cloned folder to build the docker image.

`cd ~/sentinel/vpn-node-docker`

4. Build the docker image.

`sudo docker build --file Dockerfile.prod --tag sentinel-vpn-node --force-rm --no-cache`

5. Navigate to the folder where the docker container was set up. In this case, it is the User's home directory.

`mkdir -p $HOME/.sentinel`

6. Run the image and configure the node.

`sudo docker run -it --privileged --mount type=bind,source=$HOME/.sentinel,target=/root/.sentinel -p 3000:3000 -p 1194:1194/udp sentinel-vpn-node`

### Step 3 --- Updating an existing Sentinel dVPN OpenVPN Node
===

1. Stop the running docker container.

`sudo docker stop $(sudo docker ps -aq -f ancestor=sentinelofficial/sentinel-vpn-node)`

2. Remove the older version of docker container (if present).

`sudo docker rm -f $(sudo docker ps -aq -f ancestor=sentinelofficial/sentinel-vpn-node)`

3. Remove the older version of docker image (if present).

`sudo docker rmi -f $(sudo docker images -aq -f reference=sentinelofficial/sentinel-vpn-node)`

4. Set the token value to an EMPTY STRING in the config file.

    Config file location: $HOME/.sentinel/config.data

    Example: {"token": "", "enc_method": "AES-256-CBC", "account_addr": "0x656b756e6c6335302e676c343572357232786970", "price_per_gb": 125.0}

After completing the above steps, follow the instructions on
[Method #1 (Quick Run: Download Docker Image from Docker Hub)](https://hackmd.io/ZsIiWsMLQ0Oq6FFmm_bDtQ?both#Method-1-Quick-Run-Download-Docker-Image-from-Docker-Hub) to get the node up and running again.

## SOCKS5 Sentinel Node

To **run** the sentinel node in SOCKS5, go through the following steps:

0. Configuring firewall
1. Installing docker
2. Running the **Sentinel dVPN** Socks Node
3. Updating an existing **Sentinel dVPN** SOCKS5 Node

### Step 0 --- Configuring Firewall
---

Below are the instructions for configuring the firewall:

1. First of all open the specific ports on the firewall. Do not open all the ports.

2. UFW or Uncomplicated Firewall is installed by default on Ubuntu. If it has been uninstalled for some reason, install it with

`apt-get install ufw`

3. Type the following command in the terminal to check the status of the firewall.
`ufw status verbose`

4. If firewall is inactive, then type the following command to activate it.

`ufw enable`

5. For SOCKS5 to work successfully, type the following command to allow the ports.

`ufw allow 3000`
`ufw allow 4200`
`ufw allow 4201`
`ufw allow 4202`
`ufw allow 4203`

### Step 1 --- Installing Docker
---

##### OS Requirements

Helpful docker commands to interact with the Sentinel dVPN Node
===

* List a running Sentinel dVPN Node:

* List both the running and stopped Sentinel dVPN Nodes:

* Stop a particular Sentinel Node:

* run ```sudo docker ps``` and copy the Container ID.
* run ```sudo docker stop ContainerID```

###### Note: stopping a dVPN Node does not remove the container

* Remove a particular Sentinel dVPN Node:

    ###### Note: The Sentinel dVPN Node must be stopped to be removed. Alternatively, you can use the `-f` flag to forcefully remove the Node if the node can not be stopped.

* Remove all stopped Sentinel dVPN Nodes:

* Stop all the running dVPN Nodes and remove them:

###### Note 1: In case you previously ran any version of Sentinel client, read the wallet from keystore file in .sentinel folder and use that same address for node setup

###### Note 2: once initialization sequence is complete, press ***ctrl + p + q*** to detach from the docker container and run it in the background.
