I'm interested in making my website a lot more secure and, while playing about scanning other websites, I found that one website responds to
wget console commands in such a manner that it returns the following response:
Unable to split netmask from target expression
However, the URL itself works fine when accessed from any browser, including via anonymous or pseudo-anonymous internet browsers (like TOR). I would be interested in replicating similar behavior for my website/server.
Can anyone tell me how to do this and what it is exactly that's causing this particular server behaviour?
