# Server Mangement

## Introduction

TBD

## Architecture

### Machine

The following is the server internet heirarchy. All machines except for the router has LAN address `192.168.123.x`, where `x` is listed below:

digraph {
    compound=true;

    uplink [label="NTUME" shape=box];
    router [label="D-Link" shape=box];

    subgraph cluster_host {
        label="Proxmox"

        truenas [label="TrueNAS"];
        ubuntu [label="Ubuntu 22.04"];
        dummy [shape=point, width=0, height=0, label=""];
        windows [label="Windows 10"];
        container [label="Tailscale"];
    }

    uplink -> router [label="140.112.14.126"];
    router -> dummy [label=".2", lhead=cluster_host];
    router -> truenas [label=".3"];
    router -> ubuntu [label=".4"];
    router -> windows [label=".5"];
    router -> container [label=".254"];
}

## Connecting to the server

### Wireguard

A VPN service is used to protect the server, and wireguard is used as a faster version of openvpn.

#### Installation

##### On linux systems

Install wireguard client by

sudo apt update
sudo apt install wireguard
sudo apt install resolvconf # install depending packages

##### Install on other systems

Download wireguard desktop from the [official download page](https://www.wireguard.com/install/).

#### Connect to server

First get a key from [Google drive](https://drive.google.com/drive/folders/1HMVhVpSwn54xHNHny5fu5hGFJGUBfxhs?usp=drive_link).

> Note: A key is a a directory named `peer<number>`. Please delete the keys you took since it's not sharable.

##### On desktop systems

For computers, what's relevent is the file `peer<number>.conf`. It is suggested to rename it to something like `nturt.conf` since it's used to identify the host.

##### On linux systems

Put the key `CONFIG_FILE_NAME.conf` to `/etc/wireguard/` under root permission such as `/etc/wireguard/nturt.conf`. Then the connection can be established by using

# connect
sudo wg-quick up <CONFIG_FILE_NAME>

# disconnect
sudo wg-quick down <CONFIG_FILE_NAME>

> Note: <CONFIG_FILE_NAME> for the command is ended without `.conf` extension.

##### On other desktop systems

Simply add a tunnel using the key `CONFIG_FILE_NAME.conf` and you can connect to the host.

##### On cellphones

The relevant file for cellphone is the QR code `peer<number>.png`. Just simply scan it using the cellphone app and you can connect to the host.

### VM IP address

Once the VPN connection is established, you can access to vaious virtual machines on the server by either their webpage or ssh. The respective accouts and password is at [Google doc](https://docs.google.com/document/d/1gDZSpbP-A0DcMdpqKjZ5JhPLum8GLTtg8j9Gkragjms/edit?usp=sharing).

## Setting up the server

### Proxmox
username: root

### Truenas

### Ubuntu

As easy as uploading a ubuntu image to proxmox.
username: nturt

### Wireguard

Setup via a docker container.

- github: [wireguard](https://github.com/linuxserver/docker-wireguard)

### Windows
