Quick reply

Code:
while read line
do
echo $line
Parse the line to get the IPaddress
<run nmap command for checking the >
done <"IP-Adress-File"


"The --data-length option can be used to send a fixed-length random payload to every port. If an ICMP port unreachable error (type 3, code 3) is returned, the port is closed."
Check first nmap works this way.
