Sred Proxy

To check a proxy for blacklisting, it is necessary to use special tools developed for this purpose. Many proxy-checkers provide free online IP-address verification and provide detailed information related to the proxy servers security. To get it, just enter the IP address of the proxy and click on the "Verify" button.

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 run Selenium WebDriver on a Virtual Private Server (VPS), you need to follow these steps:

Choose a VPS provider and set up your VPS instance. Some popular VPS providers include DigitalOcean, Linode, and Vultr.

Connect to your VPS instance using SSH (Secure Shell) and update the package list:

sudo apt-get update

Install the required dependencies:

sudo apt-get install -y chromedriver

Download the appropriate version of the ChromeDriver for your browser version. You can download it from the ChromeDriver download page.

Move the downloaded ChromeDriver binary to a directory in your PATH, for example, /usr/local/bin/:

sudo mv chromedriver /usr/local/bin/

Give the ChromeDriver binary executable permissions:

sudo chmod +x /usr/local/bin/chromedriver

Install the required Python packages:

pip install selenium

Create a Python script to run Selenium WebDriver on your VPS instance:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Chrome()
driver.get('https://example.com')

search_box = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.ID, 'search-box')))
search_box.send_keys('your search query')
search_box.send_keys(Keys.RETURN)

driver.quit()

Run the Python script on your VPS instance using SSH:

python your_script.py

On smartphones, when a proxy is turned on, the corresponding indicator (the "VPN" icon) appears in the status bar. In Windows you have to go to "Settings", open "Network and Internet". Under "Proxy Server", if the item "Manual" is activated, it means that the proxy is engaged right now.

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.
