There are many free VPN services. But it is not safe to use them. After all, they are just engaged in parsing. That is, they collect information about users. Most often - their IP-addresses, as well as text data (these are search queries and their personal information).

Scraping a large number of web pages using JavaScript typically involves the use of a headless browser or a scraping library. Puppeteer is a popular headless browser library for Node.js that allows you to automate browser actions, including web scraping.

Here's a basic example using Puppeteer:

Install Puppeteer:

npm install puppeteer

Create a JavaScript script for web scraping:

const puppeteer = require('puppeteer');

async function scrapeWebPages() {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();

    // Array of URLs to scrape
    const urls = ['https://example.com/page1', 'https://example.com/page2', /* add more URLs */];

    for (const url of urls) {
        await page.goto(url, { waitUntil: 'domcontentloaded' });

        // Perform scraping actions here
        const title = await page.title();
        console.log(`Title of ${url}: ${title}`);

        // You can extract other information as needed

        // Add a delay to avoid being blocked (customize the delay based on your needs)
        await page.waitForTimeout(1000);
    }

    await browser.close();
}

scrapeWebPages();

Run the script:

node your-script.js

In this example:

• Puppeteer is used to launch a headless browser and open pages.
• The urls array contains the list of web pages to scrape. You can extend this array with the URLs you need.
• Inside the loop, you can perform scraping actions using Puppeteer functions. For example, extracting data using page.title().

Keep in mind the following:

• Be aware of the legality and terms of service for web scraping on the targeted websites.
• Respect the websites' robots.txt files and use delays between requests to avoid being blocked.
• Customize the scraping logic based on the structure of the web pages you are dealing with.

Bypassing or disabling UDP client isolation on Android is not recommended, as it may expose your device to security risks and vulnerabilities. UDP client isolation is a security feature that helps protect your device from malicious traffic and potential attacks.

However, if you still want to proceed, you can try the following steps:

1. Root your Android device: Rooting your device gives you administrative access, allowing you to bypass certain restrictions and modify system files. Be aware that rooting may void your device's warranty and expose your device to security risks.

2. Edit the system configuration file: After rooting your device, you can edit the system configuration file to disable UDP client isolation. The file you need to edit is called "inet_ipv4.conf" and is located in the "/etc/sysconfig/network-scripts" directory. Open the file using a text editor and look for the line "udp_client_isolation=1". Change the value to "0" to disable UDP client isolation.

3. Reboot your device: After making the changes, save the file and reboot your device. The changes should take effect, and UDP client isolation will be disabled.

Please note that disabling UDP client isolation may expose your device to security risks, and it is not recommended to do so unless you have a specific reason and understand the potential consequences. Always consider the security of your device and data before making any changes to your system.

A Duplex UDP Communicator is a communication system that allows for two-way communication using User Datagram Protocol (UDP). To wait for a response from the other side, you can implement a simple client-server model. Here's a high-level overview of how to achieve this:

1. Server-side:

- Bind a UDP socket to a specific port on the server.
- Start a loop that continuously listens for incoming UDP packets.
- Receive the UDP packet and extract the data.
- Process the received data and prepare a response.
- Send the response back to the client using the client's address and port extracted from the received packet.
- Continue listening for incoming packets.

2. Client-side:

- Bind a UDP socket to a specific port on the client.
- Send a UDP packet to the server's address and port.
- Start a loop that continuously listens for incoming UDP packets.
- Receive the UDP packet and extract the data.
- Process the received data and prepare a response.
- Send the response back to the server using the server's address and port extracted from the received packet.
- Continue listening for incoming packets.

To wait for a response from the other side, you can use a simple time-based approach or a more advanced synchronization mechanism.

3. Time-based approach:

- After sending a packet, wait for a specific amount of time before expecting a response.
- If a response is received within the waiting time, process the response and proceed.
- If the waiting time elapses without receiving a response, handle the timeout and take appropriate action (e.g., retry, abort, or notify the user).

4. Synchronization mechanism:

- Include a unique identifier in each packet sent.
- When the server receives a packet, it sends back a response with the same identifier.
- The client waits for a response with the same identifier before proceeding.
- If a response with the same identifier is received, process the response and proceed.
- If a response with a different identifier is received, discard it and continue waiting for the expected response.
- If no response is received within a specific time, handle the timeout and take appropriate action.

Using a synchronization mechanism is more reliable than a time-based approach, as it ensures that the client only processes responses from the expected server. However, both methods can be effective depending on the specific use case and network conditions.

A proxy server is a kind of "mediator" between your equipment and a remote server (or the whole Internet). It can be used, for example, to swap your real IP address for another one, to bypass blocking. Proxies can also be actively used to intercept traffic (e.g. when testing created web applications).
