GRC ShieldsUp! Shields UP!! — System Error test of All Service Ports [the first 1056] ports on the machine yielded results as follows:
"Solicited TCP Packets: PASSED — No TCP packets were received from your system as a direct result of our attempts to elicit some response from any of the ports listed below — they are all either fully stealthed or blocked by your ISP. However . . .
Unsolicited Packets: PASSED — No Internet packets of any sort were received from your system as a side-effect of our attempts to elicit some response from any of the ports listed above. Some questionable personal security systems expose their users by attempting to “counter-probe the prober”, thus revealing themselves. But your system remained wisely silent. (Except for the fact that not all of its ports are completely stealthed as shown below.)
Ping Reply: RECEIVED (FAILED) — Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet. Most personal firewalls can be configured to block, drop, and ignore such ping requests in order to better hide systems from hackers. This is highly recommended since “Ping” is among the oldest and most common methods used to locate systems prior to further exploitation."
Trying to fix this, I first Stealthed ports with middle option, the “alert me to incoming connections and stealth my ports on a case by case basis”, then redid the GRC test. Fail again, so stealth the ports to “block all incoming connections and make my ports stealth for everyone”
AGain, the ping test failed.
Can anyone help me with the steps to take to find out which port/s are responding to the pings and then to properly silence them?
