Anchor Proxy Server

To check the quality of a proxy server, you can use one of the proxy checkers. There are a lot of them on the Internet. For example, hidemy.name. On the page of the checker you need to specify the IP-address and port of the required proxy server.

The basic configuration is written in nginx.conf file in the program directory. You need to create a server article and specify there the port number and the place for cached data. Thus, for example, by using port 8080 you may organize a local proxy to test your own sites.

To implement a constant scraping process, you can use a combination of a loop and a delay to periodically scrape data from a website. This process is often referred to as "web scraping with intervals" or "periodic scraping." Here's an example using Node.js and the axios library for making HTTP requests

Install Dependencies

Install the required npm packages:

npm install axios

Write the Scraping Script

Create a Node.js script (e.g., constant_scraping.js) with the following code:

const axios = require('axios');

async function scrapeData() {
    try {
        // Replace with your scraping logic
        const response = await axios.get('https://example.com'); // Replace with the URL you want to scrape
        console.log('Scraped data:', response.data);

        // Add additional scraping logic as needed
        // ...

    } catch (error) {
        console.error('Error during scraping:', error.message);
    }
}

// Function to perform constant scraping with a specified interval
async function constantScraping(interval) {
    while (true) {
        await scrapeData();
        await sleep(interval); // Sleep for the specified interval before the next scrape
    }
}

// Function to introduce a delay using setTimeout
function sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
}

// Set the interval (in milliseconds) for constant scraping
const scrapingInterval = 60000; // 60 seconds

// Start the constant scraping process
constantScraping(scrapingInterval);

Replace 'https://example.com' with the URL you want to scrape.

Adjust the scraping logic within the scrapeData function to meet your specific requirements.

Run the Script:

Run the script using Node.js:

node constant_scraping.js

This script defines a constantScraping function that continuously calls the scrapeData function at a specified interval using a loop and the sleep function. Adjust the interval (scrapingInterval) based on your scraping needs.

In the User Datagram Protocol (UDP), dynamic ports are assigned using a process called ephemeral port allocation. UDP is a connectionless protocol, which means that it does not establish a dedicated connection between the sender and receiver, as the Transmission Control Protocol (TCP) does. Instead, UDP sends data packets directly to the destination, and the receiver is responsible for acknowledging receipt or requesting retransmission if needed.

In UDP, both the sender and receiver have a pair of ports: one for the source and one for the destination. The source port is assigned by the sender, while the destination port is assigned by the receiver. When a connection is established, the sender assigns an ephemeral port to itself and sends the data to the destination port specified by the receiver.

The assignment of dynamic ports in UDP is typically managed by the operating system. The process generally follows these steps:

1. Ephemeral port allocation: The operating system maintains a pool of available ephemeral ports, which are typically in the range of 49152 to 65535. When a UDP connection is initiated, the operating system assigns an available ephemeral port from this range to the sender.

2. Port reuse: Once a UDP connection is closed, the ephemeral port is returned to the pool of available ports. This allows the port to be reused for subsequent connections, ensuring efficient use of the limited range of high-numbered ports.

3. Port randomization: Some operating systems implement port randomization to prevent certain types of denial-of-service (DoS) attacks. In this case, the operating system may assign an ephemeral port that is slightly higher than the requested port, adding a small random offset to the port number.

4. Destination port assignment: The destination port is assigned by the receiver and is typically determined by the application or service that the receiver is running. The destination port can be a well-known port (below 1024) or a registered port (1024-49151), or it can be a dynamic or private port (49152-65535).

In summary, dynamic ports in UDP are assigned using a combination of ephemeral port allocation and destination port assignment. The process is managed by the operating system and is designed to ensure efficient and secure communication between devices.

The first thing to do is to go into the "Settings" of the messenger. In the "Data and Memory" section, at the very bottom, are the "Proxy Settings". Activate "Use proxy" and select the protocol SOCKS5, then in the line "Server" write the address and in the line "Port" - the port of the proxy. Since SOCKS5 often uses a system of authentication, you'll need to enter your username and password in the appropriate lines. Sign the result by clicking the checkbox at the top right corner of the screen. When you have connected the proxy to Telegram, don't forget to click "Share" and select the desired contacts.
