How to mount synology SMB2 share on ubuntu

  • 772

I'm having a hard time mount a SMB2 share from my synology to ubuntu server 16.04.

mount.cifs //NAMEOFNAS.domainname.local/Backup /mnt/NAS/ -U USERNAME

results in following error:

mount error(95): Operation not supported

So checking the network share with smbclient results in another error:

 smbclient //NAMEOFNAS.domainname.local/Backup -U username
WARNING: The "syslog" option is deprecated
Enter username's password:
protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE

When doing the same but with a share on Windows server, I have no problem whatsoever. Is there something I have to configure in Synology NAS (i noticed it's configured to only use SMB2)?

Here is the output of testparm (only thing I changed was domain and security=user)

   # Global parameters
[global]
        workgroup = AVR
        server string = %h server (Samba, Ubuntu)
        server role = standalone server
        security = USER
        map to guest = Bad User
        obey pam restrictions = Yes
        pam password change = Yes
        passwd program = /usr/bin/passwd %u
        passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
        unix password sync = Yes
        syslog = 0
        log file = /var/log/samba/log.%m
        max log size = 1000
        server max protocol = SMB2
        max protocol = SMB2
        protocol = SMB2
        server min protocol = SMB2
        min protocol = SMB2
        dns proxy = No
        usershare allow guests = Yes
        panic action = /usr/share/samba/panic-action %d
        idmap config * : backend = tdb


[printers]
        comment = All Printers
        path = /var/spool/samba
        create mask = 0700
        printable = Yes
        browseable = No


[print$]
        comment = Printer Drivers
        path = /var/lib/samba/printers

What can I do to mount this share please?

    I use a PI to mount a DS Share into my nextcloud instance. For that reason I use the following mounting command:

    sudo mount.cifs -o username=ds-user,password=pw-of-ds-user,uid=33,gid=33,file_mode=0660,dir_mode=0770,vers=2.1  //IP-of-NAS/share /mountpoint/where/to/mount

    I will explain the command

    • username and password should be clear I hope
    • uid gid are the values for www-date to get it working under nextcloud
    • file_mode set the permission for the mounting point
    • dir_mode do the same for folders
    • vers=2.1 that was the most important to get it working, the version 2.0 was not working for my DS in combination with my Linux
    • and of course the the source and destination

    So you cannot copy and paste my command you must edit it to your needs, but I think the structure should be clear now.

    • edit /etc/samba/smb.conf，change smb client version 
      [global]

# SMB protocol
client min protocol = SMB2
client max protocol = SMB3
    • restart or reboot 
      # restart smb service
sudo systemctl restart smbd.service

# or reboot
sudo reboot
    • try to link your NAS server 
      smb://<nas-ip>
