Let's say I am getting no connection to a website over http, ie. "Oops! Google Chrome could not connect to x" returns in a browser. What steps can I take to determine if the server is completely offline or whether there are still some services active?
So far, I have:
confirmed an A record is returning.
getting 'destination host unreachable' from ping.
nmap replies with no services, saying that 1000 scanned ports are filtered.
nping fails to initiate a TCP handshake saying 'no route to host'.
