https://bugzilla.samba.org/show_bug.cgi?id=14713 --- Comment #37 from Stefan Metzmacher <metze@xxxxxxxxx> --- (In reply to Richard Flint from comment #33) >From 'man smb.conf' ... SMB2: Re-implementation of the SMB protocol. Used by Windows Vista and later versions of Windows. SMB2 has sub protocols available. 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 SMB2_24) 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 final). By default SMB3 selects the SMB3_11 variant. ... So '-m SMB3' is the same as '-m SMB3_11', I guess to want '-m SMB3_00' instead in order to force 3.0.0 -- You are receiving this mail because: You are the QA Contact for the bug.
