I’m trying to pass the Lab#3 of PTP course, about scanning. I tried to run the idle scan with the follow command:
nmap -Pn -sI 10.50.97.25 10.50.96.110 -p135 -v
However, I see the follow message:
Idle scan zombie 10.50.97.25 (10.50.97.25) port 80 cannot be used because it has not returned any of our probes – perhaps it is down or firewalled.
Obviosuly, port 80 on 10.50.97.25 is open, as I saw in previous task. How can implement the idle scan? I tried to see the solution too, but it don’t involve any host in the 10.50.96.0/24 network. How is it possible?
Thank you in advice.
