samba - Mar 2015 - How to know which protocol version clients use?

Hello,

I currently run samba with

    server min protocol = NT1

but I need to move towards

    server min protocol = SMB2

is there any way I can detect which clients still use the older protocol 
versions? I would like to estimate the impact of the change before i do 
close NT1/SMB1.

Thank and kind regards,

Heiner Billich

The default is "server min protocol = LANMAN1". For what reason you
need
to set this to SMB2?

What clients do you have in your network?



Ways to find out the SMB version used:

* Wireshark and Co.

* Powershell "Get-SmbConnection" cmdlet (on the client side)

* or the funny way, someone suggested a while ago here on the list:

Hi im just wondering.. 

testparm -v | grep protocol
Why is on a domain member server the max protocol SMB3 
Server role: ROLE_DOMAIN_MEMBER
Press enter to see a dump of your service definitions

        server max protocol = SMB3
        server min protocol = LANMAN1
        client max protocol = NT1
        client min protocol = CORE

And on a domain controlller 
samba-tool testparm -v | grep protocol

        server max protocol = NT1
        server min protocol = CORE
        client max protocol = NT1
        client min protocol = CORE

I would think that the DC would use SMB3 also for Max protocol.
any reason this isnt.. man smb.conf did not help me here. 


Greetz,
