Ubuntu 17.10 issue with mount cifs

Question

since the update to Ubuntu 17.10 my script to mount shares from a NAS does not work anymore. On older versions of Ubuntu I could use this line:

mount -t cifs -o username=t0b1,password=$pw //server.local/shared/ /media/shared

Adding another option to specify the version does not seem to change anything:

mount -t cifs -o vers=1.0, username=t0b1,password=$pw //server.local/shared/ /media/shared

When I run the script on Ubuntu 17.10 the only output I get is a list of options for "mount" but it does not mount my shares. Does anyone know what exactly has changed with cifs on 17.10? Any idea what I could change here?

EDIT: This line actually works:

mount -t cifs -o  username=t0b1,password=$pw,vers=1.0 //server.local/shared/ /media/shared

But I think using version 1.0 is only a temporary workaround because it has some known security issues. There should also be a way to get it running with version 3.

Solution 1

I had the same problem after upgrading to Ubuntu 17.10. Suddenly, my CIFS shares would no longer mount. Adding vers=1.0 to the mount options fixed it for me. Admittedly, this is a bit of a bodge, but some network share access is better than no network share access.

My /etc/fstab file previously had the following 4 lines at the bottom:

# Network File Shares
//phc.imsu.ox.ac.uk/phc     /mnt/PHC        cifs    credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777 0   0
//phc.imsu.ox.ac.uk/departments /mnt/DEPARTMENTS    cifs    credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777 0   0
//femur.imsu.ox.ac.uk/phc_cprd  /mnt/PHC_CPRD       cifs    credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777 0   0

Changing them to:

# Network File Shares
//phc.imsu.ox.ac.uk/phc     /mnt/PHC        cifs    credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777,vers=1.0    0   0
//phc.imsu.ox.ac.uk/departments /mnt/DEPARTMENTS    cifs    credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777,vers=1.0    0   0
//femur.imsu.ox.ac.uk/phc_cprd  /mnt/PHC_CPRD       cifs    credentials=/home/benjamin/.smbcredentials,iocharset=utf8,sec=ntlm,dir_mode=0777,file_mode=0777,vers=1.0    0   0

Resolved the issue.

Solution 2

Try this:

mount -t cifs -o vers=1.0,username=t0b1,password=$pw //server.local/shared/ /media/shared

That is, the same as your first try but without space. They are not allowed in the options. That is probably the reason why the mount does not see username ans password.

This line works but i will leave the question open. Maybe someone can come up with a solution without this workaround to use the older version.

Just to add that with similar scenario but using autofs was also solved by adding 'vers=1.0' to the existing line in auto.nfs :- USB2 -fstype=cifs,rw,bg,intr,noperm,vers=1.0,user=,password= ://192.168.1.172/USB2

worked for me too on Ubuntu 16.04.4 (Ubuntu 16.04.1 did not need it) I lost the last hour of my life beacuse of this.
