SMB

SMB service allows Windows, Mac, and other clients that support the SMB protocol to access data stored in TNAS. When the Recycle Bin function is enabled in TNAS, files deleted via SMB will be automatically moved to the Recycle Bin. If this function is not enabled, files will be permanently deleted directly. To ensure effective use of disk space, it is necessary to regularly clean the Recycle Bin.

Method for using SMB file service on a Windows PC​

Method 1:
Through the TNAS PC client application, locate and log in to your device. Once opened, click on 'Network Disk' and enter your username and password to access TNAS shared folders.

Method 2:
Enter \\TNAS IP address in the address bar of File Explorer, for example: \\192.168.0.200.

Method 3:
Open the 'Run' menu on the computer (shortcut: Windows key + R), then enter \\TNAS IP address, for example: \\192.168.1.123. Next, enter the TNAS username and password.

Method 4:
Select This PC, right-click, choose "Map network drive", enter the path of the shared folder you want to map, select a drive letter for the mapping, then enter the username and password. This will map the shared files to your Windows PC.

Note

When the "Hide folders without permission" option is enabled in SMB settings, the feature currently applies only to shared folders. For subfolders, even if the user does not have access rights, they will still be visible in the directory (cannot be hidden), but access will be denied.

Method for using SMB file service on a Mac​

Method 1:
Using the TNAS PC client application, locate and log into your device. Once opened, click on 'Network Disk', and enter your username and password to access TNAS's shared folders.

Method 2:
Open your Mac computer > Finder, click on 'Go' in the menu bar, then select 'Connect to Server'. Enter smb://TNAS IP address, for example: smb://192.168.1.123.

Note

After the user joins the AD domain, when logging in to SMB service on a Mac, a slash (/) should be added before the username, e.g., /username.

Function Description​

Enable Transfer Log:
After enabling transfer logs, operations performed on files via SMB will be recorded. You can view them by going to the TOS control panel > System Logs.

Hide Shared Folders from Unauthorized Users:
After enabling this option, users using SMB access will not be able to see shared folders for which they do not have permissions.

Enable the VFS module to convert Mac special characters:
After enabling this option, users can view files or folders in macOS using SMB access that contain special characters such as < > " * ?.

Unable to use SMB file services on Windows，strategies for handling abnormal situation​

Exception Situation:
When using "\IP" (for example, "\192.168.1.10" ) in Windows File Explorer to connect to an SMB service, it prompts "Cannot connect to the target."

Method 1:
Navigate to TOS Desktop > Control Panel > SMB File Service to check if the SMB service is enabled.

Method 2:
Navigate to TOS Desktop > Control Panel > SMB File Service, and modify the minimum and maximum SMB versions supported by TNAS.

Method 3:
Go to Windows Control Panel > Programs > Programs and Features, find and open "SMB 1.0/CIFS File Sharing Support". (It is not recommended to allow only TNAS to use SMB 1.0.)

Method 4:
Clear the computer's SMB cache/credentials and retry access:

  1. Go to Windows Control Panel > Credential Manager > Clear TNAS Windows credentials.
  2. Press Win+R to open the "Run" dialog, type cmd, and press Enter.
  3. In the Command Prompt window, type net use * /del and press Enter to delete all connections.
  4. After deleting, wait for one minute or restart the computer, then attempt to access again.

Method 5:
To modify Windows authentication settings:

  1. Open "Local Security Policy" by typing "secpol.msc" in the Windows Start menu search box and pressing Enter.
  2. Navigate to Local Policies > Security Options > Network security: LAN Manager authentication level. If it shows as "Not Defined," right-click on it and select "Properties."
  3. In the properties window, select the option "Send LM & NTLM - use NTLMv2 session security if negotiated" from the drop-down menu. Then click "Apply" and "OK" to save the changes.

Exception Situation:
When accessing SMB services, Windows prompts "File sharing is not secure, please use SMB 2 or higher versions."

Method:
Navigate to TOS Desktop > Control Panel > File Services > SMB > Advanced, and change the "Maximum SMB version" to SMB3.
