No longer able to mount NAS using CIFS I am following notes made previously on mounting my NAS on my Debian system: sudo mount -t cifs -o user=***,password=***,vers=1.0 //NAS_IP_ADDRESS/NAS_DIR /mnt/NAS This is generating the below error: mount error(95): Operation not supported Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) I remember when I had first mounted my NAS adding vers=1.0 was necessary for it to work. If I now change the version from 1 to 2 the NAS is mounted. sudo mount -t cifs -o user=***,password=***,vers=2.0 //NAS_IP_ADDRESS/NAS_DIR /mnt/NAS However on adding the below line to /etc/fstab and restarting the machine the NAS is no longer mounted: //NAS_IP_ADDRESS/NAS_DIR /mnt/NAS cifs user=***,password=***,vers=2.0,iocharset=utf8,sec=ntlm 0 0 This used to work without fail. What am I doing wrong?

Dropped the ",sec=ntlm" from fstab and it works.
