Stun Proxy

The proxy domain most often refers to the IP address where the server is located. It can only "learn" the IP address of the user when processing the traffic. But in most cases it does not store such information later for security reasons.

In Telegram on PC, proxies can be set up through the application settings. You need to open the "Advanced settings" item, then - select "Connection type". By default, the Windows system proxy is used, but you can specify it manually or disable it altogether.

Scraping data from a community wall on VK (Vkontakte) using the VK API requires authentication and making requests to the API endpoints. VK provides an official API that you can use to access various data, including posts from community walls.

Here's a general guide on how to scrape posts from a community wall using the VK API:

1. Create a VK App:

   • Go to the VK Developers website and create a VK app.
   • Obtain the "App ID" and "Secure Key" for your app.

2. Authentication:

   • Get an access token to authenticate your requests. You can use the Implicit Flow for user authentication or the Client Credentials Flow for app authentication.

3. Make API Requests:

   • Use the obtained access token to make requests to the VK API. The endpoint for getting wall posts is wall.get.
   • You'll need the community's ID or screen name to get its wall posts.

Here's an example using Python and the requests library:

import requests

# Replace with your VK app details and access token
app_id = 'your_app_id'
secure_key = 'your_secure_key'
access_token = 'your_access_token'

# Replace with the community ID or screen name
community_id = 'your_community_id_or_screen_name'

# API endpoint for getting wall posts
api_url = f'https://api.vk.com/method/wall.get?owner_id=-{community_id}&count=10&access_token={access_token}&v=5.131'

# Make the API request
response = requests.get(api_url)
data = response.json()

# Extract and print the posts
if 'response' in data and 'items' in data['response']:
    posts = data['response']['items']
    for post in posts:
        print(post['text'])
else:
    print('Error fetching wall posts')

Note: Make sure to handle errors and check the VK API documentation for more details on available parameters and responses.

To enable STL 1.0 and 1.1 support in the latest Firefox via Selenium, you can set the stlVersion preference in FirefoxOptions. Here's an example of how to do this:

First, import the necessary libraries:

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

Create a FirefoxOptions instance and set the stlVersion preference:

options = Options()
options.set_preference("services.stl.version", "1.1")

Initialize the WebDriver with the FirefoxOptions instance:

driver = webdriver.Firefox(options=options)

Use the WebDriver as usual:

driver.get('https://example.com')
# Perform actions on the web page
# ...
driver.quit()

By setting the services.stl.version preference to "1.1", you enable STL 1.1 support in the latest Firefox via Selenium. Note that the exact preference value may change depending on the Firefox version. You can check the Firefox release notes or source code for the latest information.

To check if a port is available over UDP, you can try binding to the port for a short period. If the binding is successful, the port is available. If it fails, the port is already in use. Here's a simple example in Python:

import socket

def is_port_available(port, host='127.0.0.1', timeout=2):
    with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as sock:
        try:
            sock.bind((host, port))
            sock.settimeout(timeout)
            return True
        except OSError:
            return False
        finally:
            sock.close()

if __name__ == "__main__":
    port = 12345
    if is_port_available(port):
        print(f"Port {port} is available.")
    else:
        print(f"Port {port} is not available.")

In this example, the is_port_available function creates a UDP socket and attempts to bind to the specified port and host. If the binding is successful, the function returns True, indicating that the port is available. If the binding fails, the function returns False, indicating that the port is already in use.
