Too many fingerprints match this host to give specific OS details

Question

Im using Armitage on Kali Linux 2. (Virtual box) In Armitage Im using "Quick scan (OS detect)" option. This is output log:

[*] Nmap: Nmap scan report for 192.168.1.255 
[*] Nmap: Host is up (0.0089s latency). 
[*] Nmap: All 100 scanned ports on 192.168.1.255 are filtered 
[*] Nmap: Too many fingerprints match this host to give specific OS details 
[*] Nmap: OS and Service detection performed. Please report any incorrect results at https://nmap.org/submit/
[*] Nmap done: 256 IP addresses (256 hosts up) scanned in 435.84 seconds 

It didnt detect any OS. I have already disabled firewall and its still not working.

Does anyone know how to fix this?

Solution

The address 192.168.1.255/24 is not a host address. It is the broadcast-address. That is also the reason why it says

[*] Nmap done: 256 IP addresses (256 hosts up) scanned in 435.84 seconds.

In a network with 256 IP-addresses there can only be 254 hosts, because the first address (192.168.1.0/24) is the network-ID and the last address (192.168.1.255/24) is the broadcast-address.

but still there is no hosts with detected OS. The OS is "unknown" for every host Also i was scanning 192.168.1.0/24

try typing db_nmap --min-hostgroup 96 -sV -n -T4 -O -F --version-light 192.168.1.0/24 in your Armitage console

I could reproduce it, I'll look what it means.

Thanks for helping, this whole time my VM was using NAT instead of Bridged Adapter.
