I'm thinking my firewall 'Shorewall' encompasses an extensive enough design to cover any attempts of intrusion that may occur, I do notice notwithstanding, that although ports 0 and 1 are closed, they still show up on test like grc.com's 'shields-up' port scanner.
I know that 0 <nil> is not a port and yet it is a port as 0 is a number in our world and port 1 has its function described, so why would these two ports even show up? On Debian it seems whatever firewall one uses these two ports are always visible and closed, so if port 0 is not a port and and port 1 is always closed, why do they announce themselves if pinged? -- CK -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
