List of protocols from the smb.conf(5) manpage. Looks like "NT1" is

       client max protocol (G)

           The value of the parameter (a string) is the highest protocol
level that will be supported by the client.

           Possible values are :

           ·   CORE: Earliest version. No concept of user names.

           ·   COREPLUS: Slight improvements on CORE for efficiency.

           ·   LANMAN1: First modern version of the protocol. Long
filename support.

           ·   LANMAN2: Updates to Lanman1 protocol.

           ·   NT1: Current up to date version of the protocol. Used by
Windows NT. Known as CIFS.

           ·   SMB2: Re-implementation of the SMB protocol. Used by
Windows Vista and later versions of Windows. SMB2 has sub protocols

               ·   SMB2_02: The earliest SMB2 version.

               ·   SMB2_10: Windows 7 SMB2 version.

               ·   SMB2_22: Early Windows 8 SMB2 version.

               ·   SMB2_24: Windows 8 beta SMB2 version.

           By default SMB2 selects the SMB2_10 variant.

       ·   SMB3: The same as SMB2. Used by Windows 8. SMB3 has sub
protocols available.

           ·   SMB3_00: Windows 8 SMB3 version. (mostly the same as

           ·   SMB3_02: Windows 8.1 SMB3 version.

           ·   SMB3_10: early Windows 10 technical preview SMB3 version.

           ·   SMB3_11: Windows 10 technical preview SMB3 version (maybe
