NanoKVM-USB Development

1. Local deployment

If only access through the local machine (localhost), certificates can be omitted.

Examples are provided here for Node.js and Python.

1.1. Node.js Service

  1. Open the terminal and enter the NanoKVM-USB directory in the previous step.
  2. Execute npm install -g http-server to install http-server.
  3. Execute http-server -p 8080 -a localhost to run the service.

1.2. Python Service

  1. Open the terminal and enter the NanoKVM-USB directory in the previous step.
  2. Execute python -m http.server 8080 to run the service.

1.3. Visit on browser

After the service is started, open the browser and visit http://localhost:8080.

Note that you can only use the http protocol, not the https protocol.

2. Local network deployment

If access is needed within the local area network, a certificate is required.

Examples are provided here for Node.js and Python. The difference from the above is that a certificate is required.

2.1. Generate Certificate

Make sure you have openssl installed.

  1. Open the terminal and enter the NanoKVM-USB directory in the previous step.
  2. Execute openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem.
  3. The terminal ask you to enter information. You can pressing the Enter key to skip it, or you can enter information as needed.

After completion, two files key.pem and cert.pem will be generated in the current directory.

2.2. Node.js Service

  1. Execute npm install -g http-server to install http-server.
  2. Execute http-server -p 8080 -S -C cert.pem -K key.pem to run the service.

2.3. Python Service

Create a file server.py in the NanoKVM-USB directory, and save it with the following code:

import http.server
import ssl

server_address = ('0.0.0.0', 8080)

httpd = http.server.HTTPServer(server_address, http.server.SimpleHTTPRequestHandler)
context = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
context.load_cert_chain(certfile='cert.pem', keyfile='key.pem')
httpd.socket = context.wrap_socket(httpd.socket, server_side=True)

print(f"Serving HTTPS on {server_address[0]}:{server_address[1]}")

httpd.serve_forever()

Execute python server.py to run the service。

2.4. Visit on browser

Open the browser and enter the service address, such as https://127.0.0.1:8080.

After opening the URL, you may be prompted with a "Privacy Error" and need to click to access manually:

3. Public network deployment

If you need to access it on the public network, it is recommended to use Nginx.

Here is a simple configuration example. For detailed configuration methods, please refer to the Nginx documentation.

server {
    listen 80;
    server_name your_domain.com www.your_domain.com; # Please replace with your domain name
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name your_domain.com www.your_domain.com; # Please replace with your domain name

    root /var/www/your_website; # Please replace with the NanoKVM-USB directory path
    index index.html index.htm;

    ssl_certificate /etc/nginx/ssl/cert.pem; # Please replace it with your certificate file path
    ssl_certificate_key /etc/nginx/ssl/key.pem; # Please replace it with your private key file path

    location / {
        try_files $uri $uri/ /index.html;
    }
}
