Circuit Proxy

In the "Settings" of any Android smartphone there is a "VPN" item. And there you can manually specify the parameters of the proxy, through which the connection to the Internet will be made. There, some of the programs also import ready-made scripts for proxy connections.

The tool that exists to run Selenium tests in headless mode is called "Headless Browsers". Headless browsers are browser automation tools that run without a graphical user interface (GUI). They are typically used for testing web applications without the need for a visible browser window. Some popular headless browsers include:

1. Chrome's Headless mode: Chrome's headless mode can be enabled by passing the --headless flag when launching a ChromeDriver instance.

2. Firefox's Headless mode: Firefox's headless mode can be enabled by passing the --headless flag when launching a GeckoDriver instance.

3. PhantomJS: PhantomJS is a headless browser that can be used with Selenium to run tests without a visible browser window.

4. Puppeteer: Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It can be used to run tests in headless mode.

5. HtmlUnit: HtmlUnit is a headless browser that can be used with Selenium to run tests without a visible browser window.

It's important to note that the specific implementation of running Selenium tests in headless mode may vary depending on the browser and the version of the Selenium WebDriver being used.

To send data back to the client via UDP, you can use a programming language like Python with a library like socket. Here's a step-by-step guide to help you achieve this:

1. Import the socket library:

First, import the socket library in your Python script.

import socket

2. Create a socket object:

Create a socket object using the socket.socket() function. Specify the socket family (AF_INET for IPv4) and the socket type (SOCK_DGRAM for UDP).

server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

3. Set the server address and port:

Set the server address and port to the values where you want to listen for incoming UDP packets.

server_address = ('localhost', 10000)
server_socket.bind(server_address)

4. Receive data from the client:

Use the server_socket.recvfrom() method to receive data from the client. This method returns a tuple containing the data and the client address.

data, client_address = server_socket.recvfrom(4096)

5. Process the received data:

Process the received data as needed. This could involve parsing the data, performing calculations, or any other operation.

6. Send data back to the client:

Use the server_socket.sendto() method to send data back to the client. This method takes the data to send and the client address as arguments.

response_data = b"Data processed successfully"
server_socket.sendto(response_data, client_address)

7. Close the socket:

Finally, close the socket using the server_socket.close() method.

server_socket.close()

Here's the complete example:

import socket

def process_data(data):
    # Process the received data as needed
    return "Processed data"

def send_data_back_to_client(server_socket, client_address, data):
    response_data = process_data(data)
    server_socket.sendto(response_data, client_address)

if __name__ == '__main__':
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    server_address = ('localhost', 10000)
    server_socket.bind(server_address)

    data, client_address = server_socket.recvfrom(4096)
    send_data_back_to_client(server_socket, client_address, data)

    server_socket.close()

In simple terms, it is a logically separated part of the main local or public network. It is through it that many users can use a proxy through a single server at the same time. Each connection is allocated to a separate subnet.

You need to open the settings menu, go to "Data and disk", and then - "Proxy settings". There you can enter the address, port number of the intermediate server, as well as username and password for authorization (if necessary).
