I recently set up Ubuntu server 18.04 LTS on an old laptop to use as a Plex Media server, and wanted to connect it to my existing media share on my QNAP NAS. I set this up using CIFS, and it seems to work, but every now an then i get the following message appear on the screen.

CIFS VFS: Free previous auth_key.response = 0000000076b9d676

The number at the end always changes. How do I get rid of this message??

Btw here is how I setup access to the share

Install cifs-utils

sudo apt install cifs-utils

Create mount directory

sudo mkdir /mnt/nas_media

Create credentials file

cat > ~/.smbcredentials
username=myusername
password=mypassword
ctrl+c

sudo chown root ~/.smbcredentials
sudo chmod 600 ~/.smbcredentials

Get UID for plex user account

id -u plex

I'll be using 113 as the UID for this example

Backup fstab file

sudo cp /etc/fstab /etc/fstab-old

Add share to fstab

sudo vi /etc/fstab

press i to enter insert mode go to end of file and enter a new line add the following

Note ip, sharename and username have been changed for privacy. Also vers=3.0 was set because that is the version of samba I have set on my nas.

//192.168.1.50/MyShare /mnt/nas_media cifs vers=3.0,iocharset=utf8,credentials=/home/myusername/.smbcredentials,uid=113 0 0

type :wq to save and exit vi

Load the new mount point

mount -a

btw I've also rebooted the server and the message always comes back. Plex is able to read and write to the share, so I'm not too sure why this message is coming up.

Is there anything I missed?

  • vers= is used for the SMB version and not Samba. Chances are you might be running Samba v4.3. You might want to check the protocol version on your NAS by looking up the specs. – Terrance Jun 21 '18 at 3:19
  • This also looks to just be a message and possibly nothing to worry about. systutorials.com/linux-kernels/59092/… Even my 16.04 system reports it with checking sudo journalctl -p 3 -xb – Terrance Jun 21 '18 at 3:43
  • ok thanks, i'll check into the smb vs samba version – John-Rock Bilodeau Jun 21 '18 at 12:38
