Proxy for Dataflow Kit

In the messenger settings, go to "Data and storage" and then, in the "Proxy settings" section, click "Add proxy". You can see whether a proxy is connected in Telegram by the presence of the shield icon located in the top menu bar.

When parsing RSS feeds and avoiding duplicates, you typically need to maintain a record of previously parsed items and compare new items to this record to ensure that you don't process the same item multiple times. Below is an example using Node.js and the rss-parser library, which simplifies working with RSS feeds.

Install Dependencies

Install the required npm package:

npm install rss-parser

Write the Parsing Script

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

const Parser = require('rss-parser');
const fs = require('fs');

const parser = new Parser();
const rssFeedUrl = 'https://example.com/rss-feed'; // Replace with the URL of the RSS feed

// Function to load and parse the previously processed items
function loadProcessedItems() {
    try {
        const data = fs.readFileSync('processedItems.json');
        return JSON.parse(data);
    } catch (error) {
        return [];
    }
}

// Function to save the processed items to a file
function saveProcessedItems(processedItems) {
    fs.writeFileSync('processedItems.json', JSON.stringify(processedItems, null, 2));
}

async function parseRSS() {
    const processedItems = loadProcessedItems();
    const feed = await parser.parseURL(rssFeedUrl);

    for (const item of feed.items) {
        // Check if the item has been processed before
        if (!processedItems.includes(item.link)) {
            // Process the new item (replace with your processing logic)
            console.log('New item found:', item.title);

            // Add the item link to the list of processed items
            processedItems.push(item.link);
        }
    }

    // Save the updated list of processed items
    saveProcessedItems(processedItems);
}

// Run the RSS parsing process
parseRSS();

Replace 'https://example.com/rss-feed' with the URL of the RSS feed you want to parse.

Run the Script

Run the script using Node.js:

node parse_rss.js

This script uses the rss-parser library to fetch and parse an RSS feed. It maintains a list of processed item links in a JSON file (processedItems.json). Each time the script runs, it loads the processed items, compares them to the new items in the feed, processes only the new items, and then updates the list of processed items.

Creating your own proxy server can be a complex process that requires knowledge of networking, programming, and server management. However, if you're interested in setting up a proxy server, here's a general outline of the steps you'll need to follow:

1. Choose a server: You'll need a dedicated server or a computer to act as your proxy server. Make sure the server has a stable internet connection and sufficient resources (RAM, storage, and bandwidth) to handle the traffic.

2. Install an operating system: Install a suitable operating system on your server, such as Linux (e.g., Ubuntu, CentOS, or Debian).

3. Configure the server: Set up your server by configuring the firewall, routing, and network settings. You may need to edit configuration files or use command-line tools to make these changes.

4. Install a proxy server software: Choose a proxy server software or platform to run on your server. Some popular options include Squid, Privoxy, and Caddy. Install the software using the package manager for your operating system (e.g., apt-get for Debian-based systems or yum for CentOS-based systems).

5. Configure the proxy server: Open the configuration file for your proxy server software (usually a text file) and edit the settings to match your requirements. You'll need to configure the listening port, IP addresses to forward requests to, and other settings such as authentication, logging, and caching.

6. Test the proxy server: Once you've configured the proxy server, test it to ensure it's working correctly. You can use online tools or test it with your web browser by configuring the browser to use your proxy server.

7. Secure the proxy server: Implement security measures to protect your proxy server from unauthorized access and potential attacks. This may include setting up a firewall, using strong authentication, and keeping the server software up to date with the latest security patches.

8. Maintain and monitor: Regularly monitor the performance and security of your proxy server, and perform routine maintenance tasks such as updating software, checking logs, and ensuring sufficient resources are available.

If you are having trouble adding a SonarQube server authentication token to Jenkins, follow these steps to troubleshoot and resolve the issue:

1. Verify SonarQube server URL and credentials: Ensure that you have the correct SonarQube server URL and credentials (username and password) for the authentication token. Double-check for any typos or errors in the information.

2. Generate a new authentication token: If you have already used the current authentication token or it has expired, generate a new one from the SonarQube server. To do this, log in to the SonarQube server, navigate to "Administration" > "Security" > "General Settings," and click the "Generate" button next to the "Authentication token" field. Copy the new token.

3. Update Jenkins with the new authentication token: In the Jenkins "Manage Jenkins" section, click on "Configure System." Scroll down to the "SonarQube Servers" section and select the SonarQube server you want to configure. Enter the updated SonarQube server URL, username, and the new authentication token in the respective fields. Save the changes.

4. Verify Jenkins plugin version: Ensure that you are using the latest version of the SonarQube Scanner plugin for Jenkins. Outdated plugins might not be compatible with the latest SonarQube server version. To update the plugin, go to "Manage Jenkins" > "Manage Plugins," find the SonarQube Scanner plugin, and click "Update."

5. Check Jenkins job configuration: Verify that your Jenkins job is configured to use the SonarQube server you just updated. In the job configuration, under the "Build" section, ensure that the "Analyze source code with SonarQube" checkbox is selected and the correct SonarQube server is selected from the dropdown menu.

6. Test the connection: Run a test Jenkins job to see if the connection to the SonarQube server is successful. If the job fails, check the console output for any error messages related to the SonarQube server or authentication token.

If you continue to face issues, consult the Jenkins and SonarQube documentation, or reach out to their support communities for further assistance.

The main task is to monitor traffic on the local network, as all requests will be handled by an organized proxy. Most often it is used to block access to certain resources in offices.
