Since the update to version 4.13 of the linux kernel my laptop running Arch Linux at first couldn't connect to the Windows 7 machines in my home network anymore. I've figured out that this is due to the update of the SMB protocol from version 1 to 3 and since Windows 7 runs on 2.1 the Arch laptop wasn't compatible to it any longer.
My problem now is: At first I had to set it back to version 1 in order to be able to connect my Arch notebook to the Windows 7 machines, albeit Windows 7 should use the protocol version 2.1 (client max protocol = NT1 instead of SMB2 or SMB2_10). Now (for whatever reason) it does work with SMB2_10 and even without using the "client max protocol" option at all, but when I connect with smbclient -L, I get the message that the client is "Reconnecting with SMB1 for workgroup listing," and when I force the smbclient to use 2.1 (client min protocol = SMB2_10), I get the response: "SMB1 disabled -- no workgroup available."
Is it possible to setup my Samba configuration in a way that the client actually uses SMB 2.1 when connecting to Windows 7?
