F4m Proxy

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.

Yes, it is possible to use Selenium without opening a visible browser window by using headless mode. Headless mode allows the browser to run in the background without displaying the graphical user interface. This can be useful for running automated tests or web scraping processes without the overhead of a visible browser.

Here's an example of how to use headless mode with Selenium in Python:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

# Create ChromeOptions and set headless mode
chrome_options = Options()
chrome_options.add_argument('--headless')

# Create WebDriver instance with headless mode
driver = webdriver.Chrome(options=chrome_options)

# Your Selenium script...

# Close the browser when done
driver.quit()

In this example:

chrome_options.add_argument('--headless') is used to enable headless mode for Chrome.

You can apply a similar approach for other browsers like Firefox:

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

# Create FirefoxOptions and set headless mode
firefox_options = Options()
firefox_options.headless = True

# Create WebDriver instance with headless mode
driver = webdriver.Firefox(options=firefox_options)

# Your Selenium script...

# Close the browser when done
driver.quit()

Headless mode is beneficial for scenarios where you don't need to visually inspect the browser while the script is running, and it can also help in improving the performance of your automated processes. Keep in mind that certain actions, especially those related to rendering and interaction with the visible browser, may behave differently in headless mode.

If your proxy server is not responding, follow these troubleshooting steps:

1. Check the proxy server settings: Ensure that the proxy server address, port, and authentication details (if required) are correct in your browser or application settings.

2. Verify the proxy server status: Visit the proxy server's website or contact the provider to check if the server is currently operational.

3. Restart the proxy server: If you have created your own proxy server, restart the server to resolve any temporary issues.

4. Test the network connection: Check your internet connection to ensure it's stable and working properly. You can try accessing other websites to determine if the issue is specific to the proxy server.

5. Update the software: Make sure you're using the latest version of the browser or application that is configured to use the proxy server. An outdated version might not be compatible with the proxy server.

6. Disable other security software: Temporarily disable any firewalls, antivirus software, or VPNs that might be interfering with the proxy server's operation.

7. Check for network restrictions: Ensure that your network (e.g., workplace, school, or ISP) is not blocking the proxy server or specific websites you're trying to access.

8. Contact the proxy server provider: If the issue persists, contact the proxy server provider for further assistance. They may be able to provide more specific troubleshooting steps or identify any ongoing issues with their service.

Several virtual proxy servers can be created within one device. These are special dedicated servers that only "service" such traffic. Many devices can connect to them at the same time.

On the PC you can use SOCKS5 proxies, for example, through the browser Firefox. There are such a function in the settings, you just need to activate it. The only nuance: the connection speed or ping indicators in this case may be slowed down.
