samba - May 2017 - define defaults for mount -t cifs

Hi,

Is there a place where I can specify defaults options a for "mount -t
cifs"?

I would like to change the default protocol version to vers=2.1

Is there something like a cifs.conf or such...?

No, there isn't. You can add entries in your fstab file with share,
mountpoints and options there but that has to be done for each share you
plan to mount, probably not what you want.

You could make a wrapper script around mount.cifs that would check or add
the vers option. Something like this pseudo code:

    if "vers" in $opts:
        if val("vers", $opts) < 2.1:
            err("min supported version is 2.1")
    else:        
        set("vers", $opts, 2.1)
     
    call mount.cifs $share $mnt -o $opts

Hai MJ,

Have you tried: 

apt-get install cifs-utils if its not installed. 
man mount.cifs  ( if cifs-utils isnt installed no mount.cifs on debian.) 

And test with : 
mount.cifs //server/share /mnt/point -o vers=2.1 

Greetz, 

Louis

But that has nothing to do with my question, the mounts work, I just 
want to make mount.cifs use vers=2.1 as a minimum.

Short background WHY::
I am using a piece of software called pydio that uses mount.cifs to 
mount samba shares.
Adjusting the way pydio executes mount.cifs does not work, and all 
mounts end up with the default vers=1.0

Sure: easiest would be to edit pydio config, but since that turns out to 
be difficut, I thought I'd try to change the default vers of mount.cifs 
to vers=2.1

Interesting suggestion. Thank you!
