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.
To run Firefox with Selenium and connected extensions, you'll need to use the FirefoxDriverService and FirefoxOptions. You can also set the path to the Firefox executable and the path to the extensions' .xpi files using the FirefoxBinary and FirefoxProfile classes. Here's an example of how to do this:
Install the required NuGet packages:
Install-Package OpenQA.Selenium.Firefox.WebDriver -Version 3.141.0
Install-Package OpenQA.Selenium.Support.UI -Version 3.141.0
Create a method to add extensions to the Firefox profile:
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using System.IO;
using System.Linq;
public static IWebDriver CreateFirefoxDriverWithExtensions(string[] extensionPaths)
{
var firefoxOptions = new FirefoxOptions();
var firefoxBinary = new FirefoxBinary(Path.GetDirectoryName(FirefoxDriverService.DefaultServicePath));
var firefoxProfile = new FirefoxProfile();
// Add extensions to the Firefox profile
foreach (var extensionPath in extensionPaths)
{
var extensionFile = new FileInfo(extensionPath);
if (extensionFile.Exists)
{
firefoxProfile.AddExtension(extensionPath);
}
}
firefoxOptions.BinaryLocation = firefoxBinary.Path;
firefoxOptions.Profile = firefoxProfile;
// Start the FirefoxDriverService with the specified Firefox binary
var driverService = FirefoxDriverService.CreateDefaultService(firefoxBinary.Path, FirefoxDriverService.DefaultPort);
driverService.EnableVerboseLogging = true;
// Create the FirefoxDriver with the specified options
var driver = new FirefoxDriver(driverService, firefoxOptions);
return driver;
}
Use the CreateFirefoxDriverWithExtensions method in your test code:
using OpenQA.Selenium;
using System;
namespace SeleniumFirefoxExtensionsExample
{
class Program
{
static void Main(string[] args)
{
// Paths to the extensions' .xpi files
string[] extensionPaths = new[]
{
@"path\to\extension1.xpi",
@"path\to\extension2.xpi"
};
// Create the FirefoxDriver with connected extensions
using (var driver = CreateFirefoxDriverWithExtensions(extensionPaths))
{
// Set up the WebDriver
driver.Manage().Window.Maximize();
// Navigate to the target web page
driver.Navigate().GoToUrl("https://www.example.com");
// Perform any additional actions as needed
// Close the browser
driver.Quit();
}
}
}
}
In this example, we first create a method called CreateFirefoxDriverWithExtensions that takes an array of extension paths as input. Inside the method, we set up the FirefoxOptions, FirefoxBinary, and FirefoxProfile to include the specified extensions. Then, we start the FirefoxDriverService with the specified Firefox binary and create the FirefoxDriver with the specified options.
In the test code, we call the CreateFirefoxDriverWithExtensions method with the paths to the extensions' .xpi files and use the returned IWebDriver instance to interact with the browser.
Remember to replace "path\to\extension1.xpi" and "path\to\extension2.xpi" with the actual paths to the extensions' .xpi files you want to connect.
Transferring a large byte array using UDP involves breaking the data into smaller chunks and sending each chunk as a separate UDP datagram. Since UDP is a connectionless protocol, there's no guarantee that the chunks will arrive in the same order they were sent. Therefore, you'll also need to send additional information to reassemble the data correctly at the receiver side.
Here's a simple example using Python to send and receive large byte arrays using UDP:
1. Sender (Python script send_large_data.py):
import socket
def send_large_data(data, host, port):
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
chunk_size = 1024
total_chunks = len(data) // chunk_size + 1
sequence_number = 0
for i in range(total_chunks):
start = sequence_number * chunk_size
end = start + chunk_size
chunk = data[start:end]
sock.sendto(chunk, (host, port))
sequence_number += 1
sock.close()
if __name__ == "__main__":
large_data = b"This is a large byte array sent using UDP." * 100
host = "127.0.0.1"
port = 12345
send_large_data(large_data, host, port)
2. Receiver (Python script receive_large_data.py):
import socket
def receive_large_data(host, port):
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
chunk_size = 1024
total_chunks = 0
received_data = b""
while True:
data, address = sock.recvfrom(chunk_size)
total_chunks += 1
received_data += data
if len(received_data) >= (total_chunks - 1) * chunk_size:
break
sock.close()
return received_data
if __name__ == "__main__":
host = "127.0.0.1"
port = 12345
large_data = receive_large_data(host, port)
print("Received data:", large_data)
In this example, the sender script send_large_data.py breaks the large byte array into chunks of 1024 bytes and sends each chunk as a separate UDP datagram. The receiver script receive_large_data.py receives the chunks and reassembles them into the original byte array.
A proxy is responsible for forwarding traffic. Technically, it just copies the traffic and sends it to the Internet, but it also replaces various metadata (the type of equipment from which the request is sent, the port number, the IP address, and so on). Or it can be simply called a "mediator" in the computer network.
Not all routers support proxies, this nuance should be clarified with the manufacturer. But many of the routers from Asus, TP-Link, Xiaomi work well with this type of connection. All this is configured through the web interface. By the way, for some routers, custom Padavan firmware is also available. The proxy works best there, especially in the presence of the OpenVPN plugin.
