Tunneling Proxy Servers

Jsoup is a Java library for working with HTML documents. To scrape links using Jsoup, you can use its selector syntax to target the anchor elements and then extract the href attributes. Here's a simple example:

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import java.io.IOException;

public class LinkScraper {
    public static void main(String[] args) {
        String url = "https://example.com";

        try {
            // Connect to the website and get the HTML document
            Document document = Jsoup.connect(url).get();

            // Select all anchor elements
            Elements links = document.select("a");

            // Iterate over each anchor element and print the href attribute
            for (Element link : links) {
                String href = link.attr("href");
                System.out.println("Link: " + href);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Make sure to replace the url variable with the URL of the website you want to scrape.

This example connects to the specified URL, retrieves the HTML document, selects all anchor elements using the "a" selector, and then iterates over them to print the href attributes.

You need to include the Jsoup library in your project. If you are using Maven, you can add the following dependency to your pom.xml:

    org.jsoup
    jsoup
    1.14.3 

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.

A proxy for calls refers to a tool or service that acts as an intermediary between the caller and the recipient of the call. It can be used for various purposes, such as anonymity, security, or call routing. Some common types of proxy services for calls include:

1. Call forwarding: This is a service that allows incoming calls to be redirected to a different phone number, often used when the recipient is not available or unable to answer the call.

2. VoIP proxies: These are servers that facilitate voice over IP (VoIP) calls, allowing users to make and receive calls over the internet. VoIP proxies can be used for various purposes, such as hiding the caller's IP address or bypassing geographical restrictions.

3. Call masking: This is a service that hides the caller's phone number, allowing the caller to remain anonymous.

4. Call recording proxies: These are used to record incoming or outgoing calls, often used for quality assurance, training, or monitoring purposes.

5. Call routing proxies: These are used to route calls to different destinations based on specific criteria, such as time of day, location, or the caller's number.

If we are talking about disabling Telegram for Android, you need to go to "Data and Memory" and under "Proxy" find "Proxy settings". Here, under "Connections", you should disable the use of a proxy server. If we are talking about disabling Telegram for iOS, then in the "Data and memory" item, you should select "Proxy", then go to the "Use proxy" column, and then move the slider to the "Off" position.

Open the torrent and through the "Menu" enter the subsection "Connection". Under "Proxy" choose a proxy type (Socks5 is best). In the box "Proxy" put IP address of your proxy, and in the "Port" box, respectively, the port of your proxy. If you are going to use proxy authentication, you will have to give your name and password in the corresponding fields. Click "Apply".
