Ubuntu – How to mount cifs with unix extensions

cifsmountsamba

I'm trying to mount a cifs share and have unix extensions enabled, but by default mount is passing 'nounix' and I can't figure out how to change the default behavior. I've checked 'man mount.cifs' and there is no option to do the inverse of 'nounix'.

Here is my mount command:

$ sudo mount -t cifs //192.168.1.135/fooshare -o username=foouser,password=foopass,uid=baruser,gid=baruser ~/fooshare

Then when I check all the options that actually got used in the mount operation, 'nounix' is present:

$ mount | grep fooshare
//192.168.1.135/fooshare on /home/baruser/foodshare type cifs (rw,relatime,vers=default,cache=strict,username=foouser,domain=,uid=1000,forceuid,gid=1000,forcegid,addr=192.168.1.135,file_mode=0755,dir_mode=0755,nounix,serverino,mapposix,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1)

when i added ,vers=1.0 to the mount options, i changed the mount options from nounix to unix. you can check this with mount -l (unix is not an option which can be set implicit).

$ sudo mount -t cifs //192.168.1.135/fooshare ~/fooshare -o username=foouser,password=foopass,uid=baruser,gid=baruser,vers=1.0

to provide extra info:

$ sudo bash -c "echo 3 > /proc/fs/cifs/cifsFYI"

make sure you unmount the specified mount properly before setting the option. To view the status (number of current cifs mounts by):

$ cat /proc/fs/cifs/DebugData

Add sec=ntlmv2 to your line in fstab like so:

//192.168.0.10/D$/ /mnt/winshare/ cifs user,file_mode=0777,dir_mode=0777,rw,gid=1000,sec=ntlmv2,credentials=/root/creds 0 0

I had the same issue for a long time, finally fixed it today.

Ubuntu – Ubuntu 17.10 issue with mount cifs

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.
