SSL Proxy Server

Most often Yandex bans only public proxies that can be used by many users at the same time. The main reason for this is the high probability of cyber-attacks. Proxies are often used for DDoS, which means artificially overloading the server by sending a large number of requests to it every second.

To move the mouse using Selenium with C#, you can use the IJavaScriptExecutor interface to execute JavaScript commands that control the mouse movements on the web page. Here's an example of how to move the mouse to a specific element:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.UI;
using System;

namespace SeleniumMouseMoveExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Set up the WebDriver
            IWebDriver driver = new ChromeDriver();
            driver.Manage().Window.Maximize();

            // Navigate to the target web page
            driver.Navigate().GoToUrl("https://www.example.com");

            // Wait for the page to load
            WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
            IWebElement element = wait.Until(x => x.Id == "target-element");

            // Move the mouse to the element
            ((IJavaScriptExecutor)driver).ExecuteScript(
                "arguments[0].scrollIntoView();", element);
            ((IJavaScriptExecutor)driver).ExecuteScript(
                "arguments[0].style.border='2px solid red';", element);
            ((IJavaScriptExecutor)driver).ExecuteScript(
                "window.getSelection().empty();", element);
            ((IJavaScriptExecutor)driver).ExecuteScript(
                "var event = document.createEvent('MouseEvents');" +
                "event.initMouseEvent('mousemove', true, false, window, 1, 0, 0, 0, 0, false, false, false, false, 0, null);" +
                "arguments[0].dispatchEvent(event);", element);

            // Perform any additional actions as needed

            // Close the browser
            driver.Quit();
        }
    }
}

In this example, we first set up the WebDriver and navigate to the target web page. We then use the WebDriverWait class to wait for a specific element to load on the page. After that, we use the IJavaScriptExecutor interface to execute JavaScript commands that move the mouse to the element.

The scrollIntoView() method scrolls the element into view, the style.border property is used to highlight the element, and the window.getSelection().empty() method clears any existing selection. Finally, we create a custom mouse event using the createEvent method and dispatch it to the element using the dispatchEvent method.

Remember to replace "https://www.example.com" and "target-element" with the actual URL and element ID or selector of the web page and element you want to interact with.

In the User Datagram Protocol (UDP), dynamic ports are assigned using a process called ephemeral port allocation. UDP is a connectionless protocol, which means that it does not establish a dedicated connection between the sender and receiver, as the Transmission Control Protocol (TCP) does. Instead, UDP sends data packets directly to the destination, and the receiver is responsible for acknowledging receipt or requesting retransmission if needed.

In UDP, both the sender and receiver have a pair of ports: one for the source and one for the destination. The source port is assigned by the sender, while the destination port is assigned by the receiver. When a connection is established, the sender assigns an ephemeral port to itself and sends the data to the destination port specified by the receiver.

The assignment of dynamic ports in UDP is typically managed by the operating system. The process generally follows these steps:

1. Ephemeral port allocation: The operating system maintains a pool of available ephemeral ports, which are typically in the range of 49152 to 65535. When a UDP connection is initiated, the operating system assigns an available ephemeral port from this range to the sender.

2. Port reuse: Once a UDP connection is closed, the ephemeral port is returned to the pool of available ports. This allows the port to be reused for subsequent connections, ensuring efficient use of the limited range of high-numbered ports.

3. Port randomization: Some operating systems implement port randomization to prevent certain types of denial-of-service (DoS) attacks. In this case, the operating system may assign an ephemeral port that is slightly higher than the requested port, adding a small random offset to the port number.

4. Destination port assignment: The destination port is assigned by the receiver and is typically determined by the application or service that the receiver is running. The destination port can be a well-known port (below 1024) or a registered port (1024-49151), or it can be a dynamic or private port (49152-65535).

In summary, dynamic ports in UDP are assigned using a combination of ephemeral port allocation and destination port assignment. The process is managed by the operating system and is designed to ensure efficient and secure communication between devices.

The easiest way is to try to open any site or application that requires an Internet connection. If the data download goes well, then the VPN is working properly. If there is a "No connection" error, then the VPN is not working properly for some reason.

It means routing traffic from multiple devices through a single proxy server. In this way you can, for example, organize a local network in an office environment, but where all the traffic data can be viewed from the administrator's server.
