Automatic Proxy

To add a custom method to a Selenium module, you can extend the existing Selenium class and add your method to the subclass. Here's an example in Python using Selenium WebDriver

Let's say you want to add a custom method named custom_method to the WebElement class in Selenium:

from selenium.webdriver.remote.webelement import WebElement

# Define your custom method
def custom_method(self, arg1, arg2):
    # Your custom logic here
    print(f"Custom Method: {arg1}, {arg2}")

# Add the custom method to the WebElement class
WebElement.custom_method = custom_method

# Now, you can use the custom method on any WebElement instance
driver = webdriver.Chrome()
element = driver.find_element(By.XPATH, "//input[@name='username']")
element.custom_method("arg1_value", "arg2_value")

In this example:

1. We import the WebElement class from selenium.webdriver.remote.webelement.
2. We define a custom method custom_method that takes two arguments (arg1 and arg2) and prints a message.
3. We add the custom method to the WebElement class by assigning it as an attribute (WebElement.custom_method).
4. We create a WebDriver instance and find a WebElement on the page using a locator (e.g., By.XPATH).
5. We call the custom method on the WebElement instance, passing the desired arguments.

This approach allows you to extend Selenium's classes with your custom methods. Keep in mind that modifying the core Selenium classes may have consequences, and you should be careful not to override existing methods or cause conflicts with future updates.

The maximum size of an RTP (Real-time Transport Protocol) packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information.

RTP is a transport protocol specifically designed for real-time applications like audio and video streaming. It is typically used in conjunction with UDP or TCP, as it does not provide its own transport layer.

RTP packets consist of two parts:

1. Payload: This is the actual data being transmitted, which can be audio, video, or other real-time data. The payload size is determined by the application or codec being used.

2. Header: The RTP header contains metadata required for the proper processing and synchronization of the payload. The header has a fixed size of 12 bytes. The maximum size of an RTP packet can be calculated by adding the payload size and the fixed header size:

Maximum RTP packet size = Payload size + 12 bytes (RTP header)

The payload size depends on the application or codec being used. For example, if you're using an audio codec that generates 100-byte audio frames, the maximum RTP packet size would be:

Maximum RTP packet size = 100 bytes (payload) + 12 bytes (RTP header) = 112 bytes

In the case of video codecs, the payload size can be significantly larger, depending on the video resolution, compression, and frame rate.

When RTP is used over TCP or UDP, the maximum size of the RTP packet is limited by the maximum payload size supported by the underlying transport protocol. For TCP, the maximum segment size (MSS) is determined by the MTU (Maximum Transmission Unit) of the network and the TCP header size. For UDP, the maximum packet size is limited by the MTU of the network and the UDP header size.

In summary, the maximum size of an RTP packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information, as well as the underlying transport protocol's limitations.

To configure a proxy manually, you'll need to access the settings of the application or software you're using that requires a proxy server. The steps to configure a proxy manually will vary depending on the application or software. Here are some general steps for common applications:

For Web Browsers:

1. Open your web browser (e.g., Chrome, Firefox, Edge).
2. Click on the menu button (usually three horizontal lines or three dots) and select "Settings" or "Options."
3. Look for a section related to "Network settings," "Proxy settings," or "Connections."
4. In the proxy settings, you'll find fields for the proxy server address and port. Enter the proxy server address and port provided by your proxy service.
5. If your proxy server requires authentication, enter the username and password in the respective fields.
6. Save your changes and close the settings window.

For Windows:

1. Press the Windows key + R to open the Run dialog.
2. Type "inetcpl" and press Enter to open the Internet Properties window.
3. Go to the "Connections" tab, and click on "LAN settings."
4. In the LAN settings, check the box next to "Use a proxy server for your LAN" if you have a proxy server configured. Enter the proxy server address and port in the appropriate fields.
5. If your proxy server requires authentication, check the box next to "Bypass proxy server for local addresses" and enter the local IP address of the website you want to access (e.g., "127.0.0.1" for localhost).
6. Save your changes and close the Internet Properties window.

For macOS:

1. Click the Apple menu and select "System Preferences."
2. Click "Network."
3. Select the network connection you want to configure the proxy settings for (e.g., Wi-Fi, Ethernet).
4. Click the "Advanced" button.
5. Go to the "Proxies" tab.
6. Check the box next to "HTTP proxy" or "HTTPS proxy" if you have a proxy server configured. Enter the proxy server address and port in the appropriate fields. 7. If your proxy server requires authentication, click the "Security" tab and check the box next to "Proxy server is secure." Enter the username and password in the respective fields.
8. Save your changes and close the Network preferences window.

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.

First you should check if its characteristics are correct. Some proxy servers are just IP address and port number, others use so called "connection script". You need to double-check that the data was entered correctly.
