I can't identity my Linux Mint 17 machine on my home network. I use
nmap -O -v 192.168.2.28
However, I get the following output (below). I am just learning nmap, so I don't know what all of the output means. I don't have firewall up on Mint (well, not during testing). I checked
ifconfig and my router's assigned dynamic IP: they are 192.168.2.28 (it is a funky router by Bell with fancy web GUI). I have Samba running, which is (I guess) port 445. I don't yet understand what netbios is, but I am reading about it. I know that OS detection works better when more ports are open, but maybe those 2 are too generic?
I am not sure, what else I need to provide for a better question. Update: Sorry, the questions is: why can't I detect OS correctly even though this is a fairly standard install?
I am happy to submit a report to Nmap about it not being able to detect the OS, but before that I want to make sure it's not me that's the problem. Thank you!
