Hi, I am new here and trying to hack my first machine...First I established a vpn connection(access panel says connected). But when I try to run nmap scan( nmap -T4 -p- -A 10.10.10.198 ) nothing showed up so i tried to ping ( ping-c 1 10.10.10.198 ) and didn't receive anything. what could be the issue? Please answer only if its a technical issue. Is it something I have o find out by myself?
