Palladium HQ Proxy

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.

In Node.js, you can introduce delays in your scraping logic using the setTimeout function, which allows you to execute a function after a specified amount of time has passed. This is useful for implementing delays between consecutive requests to avoid overwhelming a server or to comply with rate-limiting policies.

Here's a simple example using the setTimeout function in a Node.js script:

const axios = require('axios'); // Assuming you use Axios for making HTTP requests

// Function to scrape data from a URL with a delay
async function scrapeWithDelay(url, delay) {
  try {
    // Make the HTTP request
    const response = await axios.get(url);

    // Process the response data (replace this with your scraping logic)
    console.log(`Scraped data from ${url}:`, response.data);

    // Introduce a delay before making the next request
    await sleep(delay);

    // Make the next request or perform additional scraping logic
    // ...

  } catch (error) {
    console.error(`Error scraping data from ${url}:`, error.message);
  }
}

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

// Example usage
const urlsToScrape = ['https://example.com/page1', 'https://example.com/page2', 'https://example.com/page3'];

// Loop through each URL and initiate scraping with a delay
const delayBetweenRequests = 2000; // Adjust the delay time in milliseconds (e.g., 2000 for 2 seconds)
for (const url of urlsToScrape) {
  scrapeWithDelay(url, delayBetweenRequests);
}

In this example:

• The scrapeWithDelay function performs the scraping logic for a given URL and introduces a delay before making the next request.
• The sleep function is a simple utility function that returns a promise that resolves after a specified number of milliseconds, effectively introducing a delay.
• The urlsToScrape array contains the URLs you want to scrape. Adjust the delay time (delayBetweenRequests) based on your scraping needs.

Please note that introducing delays is crucial when scraping websites to avoid being blocked or flagged for suspicious activity.

Building a chain of proxies in Selenium involves configuring a WebDriver with a Proxy object that represents a chain of proxies. Here's an example using Python with Selenium and the Chrome WebDriver:

from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

# Create a Proxy object for the first proxy in the chain
proxy1 = Proxy()
proxy1.http_proxy = "http://proxy1.example.com:8080"
proxy1.ssl_proxy = "http://proxy1.example.com:8080"
proxy1.proxy_type = ProxyType.MANUAL

# Create a Proxy object for the second proxy in the chain
proxy2 = Proxy()
proxy2.http_proxy = "http://proxy2.example.com:8080"
proxy2.ssl_proxy = "http://proxy2.example.com:8080"
proxy2.proxy_type = ProxyType.MANUAL

# Create a Proxy object for the final proxy in the chain
proxy3 = Proxy()
proxy3.http_proxy = "http://proxy3.example.com:8080"
proxy3.ssl_proxy = "http://proxy3.example.com:8080"
proxy3.proxy_type = ProxyType.MANUAL

# Create a chain of proxies
proxies_chain = f"{proxy1.proxy, proxy2.proxy, proxy3.proxy}"

# Set up ChromeOptions with the proxy chain
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f"--proxy-server={proxies_chain}")

# Create the WebDriver with ChromeOptions
driver = webdriver.Chrome(options=chrome_options)

# Now you can use the driver with the proxy chain for your automation tasks
driver.get("https://example.com")

# Close the browser window when done
driver.quit()

In this example:

Three Proxy objects (proxy1, proxy2, and proxy3) are created, each representing a different proxy in the chain. You need to replace the placeholder URLs (http://proxy1.example.com:8080, etc.) with the actual proxy server URLs.

The ProxyType.MANUAL option is used to indicate that the proxy settings are configured manually.

The proxies_chain variable is a comma-separated string representing the chain of proxies.

The --proxy-server option is added to ChromeOptions to specify the proxy chain.

A Chrome WebDriver instance is created with the configured ChromeOptions.

To address the "ERROR conda.core.link:_execute(637)" issue when installing Scrapy (Python 3.7) on Windows 8:

- Update conda: conda update conda
- Create a new virtual environment: conda create -n myenv python=3.7 and then conda activate myenv
- Install Scrapy using conda: conda install scrapy
- Check Python version compatibility with Scrapy.
- Alternatively, try installing Scrapy using pip: pip install scrapy
- Update Anaconda: conda update anaconda
- Temporarily disable antivirus/firewall.
- Verify network connection stability.
- If issues persist, seek assistance from community forums or provide more details for further help.

There are 2 ways to do this. The first is to manually change the settings in /etc/environment, but you will definitely need root access to do that. You can also use the Network Manager utility (compatible with all common DEs). You just have to make sure beforehand that the driver for the network adapter to work properly is installed on the system.
