Hai,
Based on what i see here :
1) running Dolphin as user, opening /Network/Shared Folders (SMB) I get an
empty window
For this I suggest first try this setting on the debian server in smb.conf
client max protocol = NT1
if that works also try, keep the highest that works.
client max protocol = SMB2
2) addressing Dolphin to open smb://casa(=workgroup) I get the error warning
Report this also @Dolhin/KDE
the network browser part is probley still at SMB1, while samba 4.9.5
defaults to SMB3
see:
https://phabricator.kde.org/D18878
3) but if I address Dolphin to directly go to smb://(remote host) or
smb://(user)@(remote host) then - after being requested and giving the
password - I CAN ACCESS the remote shares, and, as far as I could see, I can
fully operate r/w as allowed in smb.conf.
Greetz,
Louis
