I am not sure I tested it since I upgraded from Jessie to stretch : I have the following entry in my fstab //mafreebox.freebox.fr/Disque\040Dur /mnt/Fbx cifs noauto,users,rw,credentials=/etc/fbx-passwd,uid=erdavid 0 0 It used to work, now it says : @bibi:~ % mount /mnt/Fbx mount error(112): Host is down Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) Using smb:// in dolphin works, so the smb server is still working. What can be the reason ?
