Bot for distributing vpn

X3UI server setup before use

Instruction is made for Ubuntu 24.04

Manage new user

Add new user

Create new user

adduser <username>

Add new user to sudo group

usermod -aG sudo <username>

Setup ssh

Login as new user

su - <username>

Create .ssh directory

mkdir ~/.ssh && chmod 700 ~/.ssh

Create new ssh_key if needed

ssh-keygen -t rsa -b 4096

It will be the key that this application will use to connect to api

Add your public key to the authorized_keys file

vim ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

Manage ssh

Generate random port, you will use it instead of 22

echo $((20000 + RANDOM % (65535 - 20000 + 1)))

Change port in ssh.socket. Edit ListenStream=<new_port>

sudo vim /lib/systemd/system/ssh.socket

Edit ssh configuration

sudo vim /etc/ssh/sshd_config

Find, uncomment or/and edit:

1. Port <new_port>
2. PermitRootLogin no
3. PasswordAuthentication no

Reload system-daemon and sshd

sudo systemctl daemon-reload
sudo systemctl restart ssh

Make sure ssh uses new port

sudo systemctl status ssh

Make sure you can connect via ssh using new user, ssh-key and new ssh port

ssh -i ~/.ssh/<ssh_key> -p <new_port> <new_user>@<server_ip>

Enable firewall

sudo ufw allow <new_port>/tcp
sudo ufw allow 443
sudo ufw enable

Install docker

sudo apt update && sudo apt upgrade -y
sudo apt install docker-* -y

Install and setup x3ui

sudo apt install git -y
cd /srv
sudo git clone https://github.com/MHSanaei/3x-ui.git
cd 3x-ui
sudo docker-compose up -d

Create private.key and public.key for https connection

sudo openssl req -x509 -newkey rsa:4096 -nodes -sha256 -keyout private.key -out public.key -days 3650 -subj "/CN=APP"
sudo docker cp private.key 3x-ui:private.key
sudo docker cp public.key 3x-ui:public.key

Now you have 3xui running inside docker container. You can access panel using ssh port forwarding

ssh -i ~/.ssh/<ssh_key>  -L 2053:localhost:2053 -p <new_port> <new_user>@<server_ip>

Type in browser http://localhost:2053 and login to panel with login: admin, password: admin

1. Go to panel settings
   1. Set up public key and private key path to /public.key and /private.key respectively
   2. Change Time Zone to Europe/Moscow or whatever you want.
   3. Save and restart panel
2. Setup TelegramBot (optional)

Then add this server to telegram bot with command /add_server
