I've tried to include min protocol = SMB2 to improve the security of my local Linux machines.  But when I do this, I get time out from within KDE and Operation Not Supported from CLI.Removing the min protocol stipulation resolves this issue.  Any idea why?testparm:Load smb config files from /etc/samba/smb.confProcessing section [homes]Processing section [msc_media_public]Processing section [msc_media_personal]Processing section [printers]Processing section [print$]Loaded services file OK.WARNING: You have some share names that are longer than 12 characters.These may not be accessible to some older clients.(Eg.
