Using NMAP to find Network Device Types
Networking HowTo's - Cisco HowTo's

This time around we're  going to use NMAP for more than just a basic scan. I really like this tool with all it's switches.

So anyway to find a network device just use nmap with the "-O" switch (that's a capital letter O, for OS detection).

Here's and example where I used this command to determine that a host was a Nortel switch:

 

***Note - in the example below I had to use "sudo" because I was running the command on an Ubuntu workstation.

kshort@LinuxStudent:~$ sudo nmap -O 192.168.100.123
[sudo] password for kshort:
