Mobile Friendly Proxy

The proxy settings in Zoom are configured through the regular Windows settings. To do this, you can use the command inetcpl.cpl in "Run". Next, you need to go to the "Connection" tab, click on "Network Setup". In the dialog box that opens, select "Proxy server" and set the required parameters. As a port, you can use 80 and 443.

To upload files using Selenium, you can follow these general steps:

Locate the file input element: Use Selenium's methods like find_element_by_id(), find_element_by_name(), or find_element_by_xpath() to locate the file input element on the webpage.

Send keys to the file input element: Use the send_keys() method to send the file path to the file input element. This will upload the file.

Here's an example using Python:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys

# Replace 'your_url' with the URL of the webpage you want to open
driver = webdriver.Chrome()
driver.get('your_url')

# Replace 'file_input_id' with the ID of the file input element on the webpage
file_input = driver.find_element(By.ID, 'file_input_id')

# Replace 'path/to/your/file' with the path to the file you want to upload
file_path = 'path/to/your/file'
file_input.send_keys(file_path)

# Rest of your code

driver.quit()

Keep in mind that the specific method to locate the file input element and the file input element's ID or name may vary depending on the webpage you're working with.

Additionally, some websites may have specific requirements or restrictions for uploading files. In such cases, you may need to use JavaScript or other methods to bypass these restrictions. If you encounter any issues or need further assistance, please provide more information about the webpage and the specific error message or problem you're facing.

To test a UDP sender, you can create a mock UDP client that simulates the behavior of the real UDP client. This way, you can test the sending functionality without actually sending data over the network.

Here's an example of how to create a mock UDP client and write a unit test for a UDP sender in C#:

1. Create a mock UDP client class:

public class MockUdpClient : IDisposable
{
    private readonly byte[] _receivedBytes;
    private int _receivedCount;

    public MockUdpClient()
    {
        _receivedBytes = new byte[1024];
        _receivedCount = 0;
    }

    public void Receive(byte[] data, int length)
    {
        Array.Copy(data, _receivedBytes, length);
        _receivedCount++;
    }

    public void Dispose()
    {
        // Clean up any resources if needed
    }

    public int ReceivedCount => _receivedCount;

    public byte[] ReceivedData => _receivedBytes;
}

2. Modify the UDP sender to accept a mock UDP client:

public class UdpSender
{
    private readonly MockUdpClient _mockUdpClient;

    public UdpSender(MockUdpClient mockUdpClient)
    {
        _mockUdpClient = mockUdpClient;
    }

    public void SendData(string data)
    {
        var bytes = Encoding.ASCII.GetBytes(data);
        _mockUdpClient.Receive(bytes, bytes.Length);
    }
}

3. Write a unit test for the UDP sender:

[TestClass]
public class UdpSenderTests
{
    [TestMethod]
    public void TestSendData()
    {
        // Arrange
        var mockUdpClient = new MockUdpClient();
        var udpSender = new UdpSender(mockUdpClient);
        var data = "Test data";

        // Act
        udpSender.SendData(data);

        // Assert
        Assert.AreEqual(1, mockUdpClient.ReceivedCount);
        CollectionAssert.AreEqual(Encoding.ASCII.GetBytes(data), mockUdpClient.ReceivedData);
    }
}

In this example, we created a MockUdpClient class that simulates the behavior of a real UDP client. The UdpSender class now accepts a MockUdpClient as a parameter, allowing us to test the sending functionality without actually sending data over the network.

Finally, we wrote a unit test using the TestClass and TestMethod attributes from the Microsoft.VisualStudio.TestTools.UnitTesting namespace. The test method TestSendData checks whether the UdpSender class sends data correctly by comparing the received data with the expected data.

To realize receiving and transmitting UDP packets in different threads for parallel work in Java, you can use the DatagramSocket class along with the Thread class to create separate threads for receiving and transmitting. Here's an example of a simple UDP server that handles receiving and transmitting in different threads:

import java.net.*;
import java.io.*;

public class ParallelUDPServer {
    private static final int PORT = 12345;

    public static void main(String[] args) throws IOException {
        // Create a DatagramSocket for receiving UDP packets
        DatagramSocket receiveSocket = new DatagramSocket(PORT);

        // Create a thread for receiving UDP packets
        Thread receiveThread = new Thread(() -> {
            byte[] receiveBuffer = new byte[1024];
            while (true) {
                DatagramPacket receivePacket = new DatagramPacket(receiveBuffer, receiveBuffer.length);
                try {
                    receiveSocket.receive(receivePacket);
                    processReceivePacket(receivePacket);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        });

        // Create a thread for transmitting UDP packets
        Thread transmitThread = new Thread(() -> {
            while (true) {
                // Simulate sending UDP packets to a client
                sendUDPPacket("Hello from the server!", "127.0.0.1", 6789);
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        });

        // Start the threads
        receiveThread.start();
        transmitThread.start();
    }

    private static void processReceivePacket(DatagramPacket packet) {
        byte[] data = packet.getData();
        int length = packet.getLength();
        InetAddress address = packet.getAddress();
        int port = packet.getPort();

        System.out.println("Received packet:");
        for (int i = 0; i < length; i++) {
            System.out.print(data[i] + " ");
        }
        System.out.println();
        System.out.println("From: " + address + ":" + port);
    }

    private static void sendUDPPacket(String message, String host, int port) throws IOException {
        byte[] sendData = message.getBytes();
        DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length, InetAddress.getByName(host), port);
        DatagramSocket socket = new DatagramSocket();
        socket.send(sendPacket);
        socket.close();
    }
}

In this example, the ParallelUDPServer class creates two threads: one for receiving UDP packets (receiveThread) and another for transmitting UDP packets (transmitThread).

Both on a PC and on modern cell phones, a built-in utility that is responsible for working with network connections, provides the ability to set up a connection through a proxy server. You just need to enter the IP-address for connection and the port number. In the future all traffic will be redirected through this proxy. Accordingly, the provider will not block it.
