Because Adrian asked, this is with Dolphin of KDE4 from ports of March
2017. But, that's not working must be something fundamental stupid I'm
doing because it's only doing the three-way-handshake on TCP/IP and
nothing else. See below.

That's why I'm using for smbclient the option '-m SMB2'. The Dolphin
does not offer anything to configure this at all.

But, as only the SYN-SYN-ACK is done, this at this point is not the
problem because the SYN-SYN-ACK does not allow to set/ask for the SMB
version.
