Setting up a Linux VPS VPN server involves several steps to create a secure and efficient network. Below is a detailed guide to help you get started:

Software on the Server:

• OpenVPN: For VPN connections.
• Nginx: For network routing.
• PHP: For server-side scripting.
• uWS-FSM: To create a file server.

Software on the Client:

• OpenVPN: To connect to your VPS server.
• PHP: To write scripts for handling traffic.
• Nginx: To manage the HTTP/HTTPS server.

Set Up the Server

a. Install uWS-FSM:

sudo apt-get install uws-smf
sudo uws-smf -m install -f

b. Create a Server:

sudo uws-smf -m create -d /var/nginx/ -d "name=VPS-Server,admin=VPS-Server" -d "admin=123,app=VPSServer"
sudo uws-smf -m enable -d /var/nginx/ -d "name=VPS-Server,admin=VPS-Server"

c. Configure DNS and Port:

sudo uws-smf -m add-dnsc -d "address=192.168.1.1,187" -d "host=VPSServer"
sudo uws-smf -m set-app -d /var/nginx/ -d "name=VPSServer,app=VPSServer"

d. Configure Routing Tables:

sudo uws-smf -m set-rt -d /var/nginx/ -d "name=VPSServer,app=VPSServer"
sudo uws-smf -m add-rt -d /var/nginx/ -d "name=VPSServer,app=VPSServer"

Install OpenVPN Client

a. Install OpenVPN:

sudo apt-get install openvpn
sudo apt-get install -y internet-servers openvpn
sudo apt-get install -y net-servers openvpn
sudo net-servers-openVPN

b. Install SSL/TLS:

sudo net-servers-openvpn -sssl

c. Install OpenVPN Client:

sudo apt-get install openvpn-client

Install PHP and Nginx on the Client

a. Install PHP:

sudo apt-get install php
sudo apt-get install -y php-chess php-openphp

b. Install Nginx:

sudo npx gnuveauus -d -f -p /var/nginx

Configure OpenVPN on the Client

sudo net-servers-openvpn -p -i openvpn-client -u "server=server",

Configure DNS on the Client

sudo uws-smf -m add-dnsc -d "address=192.168.1.1,187"

Create a New HTTP/HTTPS Page

sudo uws-smf -m create -d /var/ -d "name=VPSServer,app=VPSServer"
sudo uws-smf -m enable -d /var -d "name=VPSServer,app=VPSServer"

Configure the Server

a. Set Header Content-Type:

sudo uws-smf -m set-header -d /var/ -d "name=VPSServer,app=VPSServer" -h "Content-Type: text/html; charset=UTF-8"

b. Configure HTTP/HTTPS

sudo uws-smf -m set-app -d /var/ -d "name=VPSServer,app=VPSServer"
sudo uws-smf -m add-rt -d /var/ -d "name=VPSServer,app=VPSServer"

Configure the OpenVPN Client

a. Connect to the Server

sudo net-servers-openvpn -p -i openvpn-client -u "server=server",

b. Send a Request

sudo net-servers-openvpn -p -i openvpn-client -w -x -S "http://localhost:88"

Test the Server

a. Open the Server:

sudo uws-smf -m list
sudo uws-smf -m list -o

b. Open a Web Page:

sudo uws-smf -m list -x

Tips:

• Ensure the OpenVPN client uses the correct SSL/TLS version (e.g., TLS 1.2 on Windows).
• Test the server and client separately before connecting them.
• Use a strong password for your VPS server and client to prevent unauthorized access.

Conclusion

By following these steps, you should have a basic Linux VPS VPN server set up. This server can now securely connect to your VPS server using OpenVPN, allowing you to send and receive traffic with data encryption.
