Nmap Tutorial For Beginners

{!} Scan a single host or IP address

$ nmap <your target IP/host>

{!}  Scan Multiple host or IP address

$ nmap <your target ip/host> <your target ip/host>

{!} Read list of hosts/networks from a file (IPv4)

Create a text file, and fill with a list of target host/ip, e.g I have make a file on directory ~/Downloads/target.txt , so just use this command.

nmap -iL ~/Downloads/target.txt

{!} Turn on OS and version detection scanning script (IPv4)

>> Default Method:

nmap -A <your target ip/host>

>> With Ping Method:

nmap -v -A 192.168.1.1

>> With List Host on File Method:

nmap -A -iL /tmp/scanlist.txt

{!} Find out if a host/network is protected by a firewall

nmap -sA <your target ip/host>

{!} Excluding hosts/networks (IPv4)

nmap 192.168.1.0/24 --exclude 192.168.1.5

method for host lisr on file:

 nmap -iL /tmp/scanlist.txt --excludefile /tmp/exclude.txt

{!} Scan a host when protected by the firewall

nmap -PN <your target ip/host>

{!}  Scan an IPv6 host/address
