Some useful nmap scans
Using nmap to inventory a network
The following command with nmap with root privilegies (or using sudo):
sudo nmap -n -sP 192.168.0.0/24 | awk '/Nmap scan report/{printf $5;printf "\t";printf $6;printf "\t";getline;getline;print $3;}' | awk '{printf $2;printf " ---> ";printf $1;printf "\n";}'
results in:
00:10:18:5D:B0:10 ---> 192.168.0.1 28:C6:8E:F9:B8:BF ---> 192.168.0.2 28:C6:8E:29:9D:30 ---> 192.168.0.3 ...
(Good luck typing that in by hand...)
Want DNS?:
sudo nmap -sP 192.168.0.0/24 | awk '/Nmap scan report/{printf $5;printf "\t";printf $6;printf "\t";getline;getline;print $3;}' | awk '{printf $3;printf " ---> ";printf $1;printf "\n";}'
results in:
00:10:18:5D:B0:10 ---> zathras.tinkernow.net 28:C6:8E:F9:B8:BF ---> switcha.tinkernow.net 28:C6:8E:29:9D:30 ---> wap1.tinkernow.net ...
or both name & address?:
sudo nmap -sP 192.168.0.0/24 | awk '/Nmap scan report/{printf $5;printf "\t";printf $6;printf "\t";getline;getline;print $3;}' | awk '{printf $3;printf " ---> ";printf $2;printf "\t";printf $1;printf "\n";}'
results in:
00:10:18:5D:B0:10 ---> (192.168.0.1) zathras.tinkernow.net 28:C6:8E:F9:B8:BF ---> (192.168.0.2) switcha.tinkernow.net 28:C6:8E:29:9D:30 ---> (192.168.0.3) wap1.tinkernow.net ...
But, for some reason, lack of a name causes odd formatting. And, nmap seems to fail to give the mac address of the machine doing the scan.
