Hi mates,
My doubt is about using telnet to see open ports remotely.
For example, there are sometimes when you use telnet x.x.x.x (port) to check open ports right ?
So, if I'm checking DNS (port 53) to see if it is running, and I don't receive responses it means the port is closed ?
because I did the same with a public DNS (8.8.8.8) and I get a prompt when using cmd.
Thanks for any advice....
