The Services > SMB screen displays after going to the Shares screen, finding the Windows (SMB) Shares section, and clicking+ Config Service. Alternatively, you can go to System Settings > Services and click the edit icon for the SMB service.
The SMB Services screen displays setting options to configure TrueNAS SMB settings to fit your use case. In most cases, you can set the required fields and accept the rest of the setting defaults. If you have specific needs for your use case, click Advanced Options to display more settings.
Enter the name of the TrueNAS host system if not the default displayed in NetBIOS Name. This name is limited to 15 characters and cannot be the Workgroup name.
Enter any alias name or names that do not exceed 15 characters in the NetBIOS Alias field. Separate each alias name with a space between them.
Enter a name that matches the Windows workgroup name in Workgroup. TrueNAS detects and sets the correct workgroup from these services when unconfigured with enabled Active Directory or LDAP active.
If using SMB1 clients, select Enable SMB1 support to allow legacy SMB1 clients to connect to the server. Note: SMB1 is deprecated. We advise you to upgrade clients to operating system versions that support modern SMB protocol versions.
If you plan to use the insecure and vulnerable NTLMv1 encryption, select NTLMv1 Auth to allow smbd attempts to authenticate users. This setting enables backward compatibility with older versions of Windows, but we don’t recommend it. Do not use on untrusted networks.
Enter any notes about the service configuration in Description
For more advanced settings, see SMB Services Screen.
Use Auxiliary Parameters to enter additional smb.conf options, or to log more details when a client attempts to authenticate to the share, add
log level = 1, auth_audit:5. Refer to the [Samba Guide]9http://www.oreilly.com/openbook/samba/book/appb_02.html) for more information on these settings.
Start the SMB service.
