https://bugzilla.samba.org/show_bug.cgi?id=14713 --- Comment #28 from Steve French <sfrench@xxxxxxxxx> --- > fear is that some flag is set wrong, maybe during negotiation There isn't an obvious reason why any of the flag differences would matter (unless server bug), but it should be possible to test mount with smb3.1.1 (without encryption) by changing the server config line server_encrypt_data=true and make sure server doesn't hang up on tree connect (as it does with encryption) If we verify that wireshark can decrypt it, then the only strange guesses I can think of that would cause the server to give up on the tree connect are: 1) difference in tree connect flags with smb3.1.1 2) differences in padding of the tree connect request that confuse the server -- You are receiving this mail because: You are the QA Contact for the bug.
