Linxology Proxy

To find out the port of the proxy server, you just need to use any browser (Yandex Browser, Opera, Google Chrome). Then you need to follow the algorithm:

Start the browser. Go to "Settings". In the search box enter the query "proxy". Click on "Proxy settings". In the window that opens, select "Network settings". This will open a tab with the IP address and port of the proxy server.

To install the Selenium library in C# for Visual Studio, you can use the NuGet Package Manager, which is integrated into Visual Studio. Follow these steps to install Selenium in your C# project:

1. Open Visual Studio:

   • Launch Visual Studio and open your C# project.

2. Open the Package Manager Console:

   • Go to View -> Other Windows -> Package Manager Console to open the Package Manager Console.

3. Run the Install-Package Command:

   • In the Package Manager Console, run the following command to install the Selenium.WebDriver package:

Install-Package Selenium.WebDriver

• • Press Enter to execute the command. This will download and install the Selenium WebDriver package and its dependencies.

• Verify Installation:

  • After the installation is complete, you should see output indicating that the package has been installed successfully.

• Install Selenium.Support (Optional):

  • Depending on your requirements, you may also want to install Selenium.Support, which includes additional support classes and utilities for Selenium. Run the following command:

Install-Package Selenium.Support

Add Using Statements in Your Code:

• In your C# code file, add the following using statements at the top:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;  // Use the appropriate browser namespace (e.g., Firefox, Edge, etc.)

• • Choose the appropriate browser namespace based on the WebDriver you plan to use (e.g., Chrome, Firefox).

• Download WebDriver Executable (Optional):

  • If you are using a specific browser (e.g., Chrome, Firefox), you need to download the corresponding WebDriver executable.

  • Place the WebDriver executable in a location accessible to your project.

• Instantiate WebDriver in Your Code:

  • In your C# code, instantiate the WebDriver using the downloaded WebDriver executable path. For example, for Chrome:

IWebDriver driver = new ChromeDriver("path/to/chromedriver");

8. • Replace "path/to/chromedriver" with the actual path to your ChromeDriver executable.

   • Ensure that you manage the WebDriver instance properly (e.g., closing it after use).

That's it! You have successfully installed the Selenium library in your C# project. You can now use the Selenium WebDriver to automate browser interactions in your C# application.

To reduce constant repetition of find_element() in Selenium, you can use the following techniques:

Store elements in variables:

When you locate an element once, store it in a variable and reuse it throughout the script. This reduces the need to call find_element() multiple times.

from selenium import webdriver

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

# Store the element in a variable
element = driver.find_element(By.ID, "element-id")

# Reuse the element
element.click()

Use loops and lists:

If you need to interact with multiple elements, store them in a list and use a loop to iterate through the elements.

from selenium import webdriver

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

# Find all elements and store them in a list
elements = driver.find_elements(By.CLASS_NAME, "element-class")

# Iterate through the list and interact with each element
for element in elements:
    element.click()

Use explicit waits:

Use explicit waits to wait for an element to become available or visible before interacting with it. This reduces the need to call find_element() multiple times, as the script will wait for the element to be ready.

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

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

# Wait for the element to become visible
wait = WebDriverWait(driver, 10)
visible_element = wait.until(EC.visibility_of_element_located((By.ID, "element-id")))

# Interact with the element
visible_element.click()

Use the all_elements_available attribute:

The all_elements_available attribute is available in some browser drivers, such as ChromeDriver. It returns a list of all elements that match the given selector. You can use this attribute to interact with multiple elements without using loops.

from selenium import webdriver

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

# Get a list of all elements that match the selector
elements = driver.find_elements(By.CLASS_NAME, "element-class")

# Interact with each element
for element in elements:
    element.click()

Remember to replace "https://www.example.com", "element-id", "element-class", and other elements with the actual values for the website you are working with. Also, ensure that the browser driver (e.g., ChromeDriver for Google Chrome) is installed and properly configured in your environment.

In the browser settings, select "Open Browser Settings" and then, finding the "Advanced" button, go to the "System" section. Click on the button "Open proxy server settings for computer" and in the section "Manual proxy settings" move the slider to the position "On". Now enter in the appropriate fields the IP address, proxy, port and click "Save".

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.
