[Samba] how to know SMB protocol versions supported by a host

[Thibault Roulet]

Hi,

Under linux you can run something like this:

nmap -p139 --script smb-protocols <server-address>

it will report something like:

PORT    STATE SERVICE
139/tcp open  netbios-ssn

Host script results:
| smb-protocols:
|   dialects:
|     2.0.2
|     2.1
|     3.0
|     3.0.2
|_    3.1.1

Cheers.
