For more details on the socket module, visit Chapter 3, Socket Programming. Here, we will only focus on using this module to extract information from servers.

Extracting server banners with Python

Banners display information related to the web server name and the server version. Some exhibit the backend technologies used (PHP, Java, or Python) and its version.

The production version may have public or non-public failures, so it's always a good practice to test the banners that return the servers we've exposed publicly, to see whether they expose some kind of information we don't want to be public.
