Ubuntu – Ubuntu 17.10 issue with mount cifs

17.10cifsmountsamba

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.

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.
