SSH Proxy Firefox

In the "System Settings" section, open the "Network" tab, and then, when you highlight the active connection, click "Advanced". Here, in the "Proxies" tab, tick only the HTTP proxy if you do not intend to use other types of proxies temporarily. Enter the address of your proxy server and its port in the designated fields and click "OK".

To enable proxies in your MacBook, you need to go to "System Preferences" (from the "Apple" menu), then open "Network", then - specify the type of connection you are using. Then select "Advanced Settings" (can be named as "Advanced"), then click on "Proxy". And then - either set the parameters manually, or specify a configuration file.

To send a UDP request to a STUN server in C++, you can use the following example code. This example uses the boost::asio library for handling asynchronous I/O operations and boost::beast for handling UDP communication. Make sure you have the Boost library installed on your system before running this code.

#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 

namespace http = boost::beast::http;

using tcp = boost::asio::ip::tcp;
using udp = boost::asio::ip::udp;

int main(int argc, char* argv[]) {
  if (argc != 3) {
    std::cerr << "Usage: stun_udp_request  " << std::endl;
    return EXIT_FAILURE;
  }

  boost::asio::io_context ioc;
  udp::resolver resolver(ioc);
  udp::resolver::results_type results = resolver.resolve(argv[1], argv[2]);

  if (results.empty()) {
    std::cerr << "Cannot resolve: " << argv[1] << ":" << argv[2] << std::endl;
    return EXIT_FAILURE;
  }

  udp::socket udp_socket(ioc);
  udp_socket.connect(results.begin()->endpoint());

  // Prepare the STUN Binding Request
  std::string stun_request =
      "BINDING_REQUEST\r\n"
      "MIXED_RELAY\r\n"
      "USER-AGENT: STUN-UDP-Example\r\n"
      "\r\n";

  // Send the STUN Binding Request
  boost::system::error_code ignored_error;
  udp_socket.send_to(boost::asio::buffer(stun_request), results.begin()->endpoint(), 0, ignored_error);

  // Receive the STUN Binding Response
  boost::beast::flat_buffer buffer;
  http::response response;
  udp_socket.receive_message(buffer, response);

  // Print the STUN Binding Response
  std::cout << "STUN Binding Response:\n";
  std::cout << response.what() << std::endl;

  return EXIT_SUCCESS;
}

To compile the example, you can use the following command:

g++ -std=c++17 -o stun_udp_request stun_udp_request.cpp -lboost_system -lboost_as

Using UDP, you can request data from a server by sending a request message to the server. Since UDP is a connectionless protocol, you need to know the server's IP address and port to send the request. The server should have a predefined mechanism to handle incoming requests and return the desired data as a response.

Here's a high-level overview of how to request data from a server using UDP:

1. Prepare your request message: Create a message containing the data you want to request from the server. The format of the message depends on the specific application and data you're working with.

2. Send the request message to the server: Use a UDP socket to send the request message to the server's IP address and port. The server should be listening for incoming UDP packets on that address and port.

3. Receive the response from the server: The server processes the incoming request and sends back a response. Use a UDP socket to receive the response on the same or a different port, depending on the application's requirements.

4. Process the response: Extract the desired data from the response and process it as needed.

Here's an example using Python:

import socket

# Prepare the request message
request_message = b"REQUEST_DATA"

# Create a UDP socket
client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# Send the request message to the server
server_address = ('127.0.0.1', 12345)
client_socket.sendto(request_message, server_address)

# Receive the response from the server
response_message, server_address = client_socket.recvfrom(1024)

# Process the response
print(f"Received response: {response_message}")

# Close the socket
client_socket.close()

In this example, the sendto() function sends a request message to the server, and the recvfrom() function receives the response from the server. The server should be running and listening for incoming UDP packets on the specified address and port.

After editing is complete, the proxy must be disabled in order to send the video for color correction. To do this, select all the proxies in the project window and choose the "Switch offline" command from the context menu. Then, after making sure that the "Media files remain on disk" option is active, click "Ok". If after that the program monitor window is filled with red color, do not be frightened, it is normal.
