General Settings Screen
Figure 1: General Settings Screen

The Manage Configuration dropdown provides three options to backup, restore, or reset system configuration settings.

Manage Configuration

TrueNAS allows users to manage the system configuration via uploading/downloading configurations, or resetting the system to the default configuration.

Download File

The Download File option opens the Save Configuration dialog, which allows users to download the current system configuration to the local machine.

Save Configuration
Figure 2: Save Configuration

The Export Password Secret Seed option includes encrypted passwords in the downloaded configuration file. This option allows you to restore the configuration file to a different operating system device where the decryption seed is not already present. Users must physically secure configuration file backups containing the seed to prevent unauthorized access or password decryption.

Upload File

The Upload File option opens the Upload Config dialog, which allows users to choose a previously saved TrueNAS configuration to replace the current system configuration.

Upload Config
Figure 3: Upload Config

Choose File opens a file browser window where you can locate the downloaded and saved configuration. After selecting the file, it displays in the Upload Config window. Upload uploads the selected configuration file.

All passwords reset if the uploaded configuration file saved without Export Password Secret Seed enabled.

Reset to Defaults

The Reset to Defaults option opens the Reset Configuration dialog, which resets the system configuration to factory settings and restarts the system. Users must set a new login password.

Reset Configuration
Figure 4: Reset Configuration

Save the system current configuration with the Download File option before resetting the configuration to default settings.

If you do not save the system configuration before resetting it, you may lose data that you did not back up, and you will not be able to revert to the previous configuration.

Support Widget

The Support widget displays general hardware and software specs and contains links to the Documentation Hub, TrueNAS Forums, and offers TrueNAS Licensing information.

Click Here for More Information

Click Settings to open the GUI Settings screen.

SettingDescription
ThemeSelect a preferred color theme from the dropdown list of eight options.
GUI SSL CertificateSelect a self-signed certificate from the dropdown list. The system uses a self-signed certificate to enable encrypted web interface connections. Manage Certificates opens the Certificates screen.
Web Interface IPv4 AddressSelect a recent IP address from the dropdown list to limit usage when accessing the administrative GUI. The built-in HTTP server binds to the wildcard address of 0.0.0.0 (any address) and issues an alert if the specified address becomes unavailable.
Web Interface IPv6 AddressSelect a recent IPv6 address from the dropdown list to limit the usage when accessing the administrative GUI. The built-in HTTP server binds to the wildcard address of 0.0.0.0 (any address) and issues an alert if the specified address becomes unavailable.
Web Interface HTTP PortEnter a port number for an HTTP connection to the web interface. Allow configuring a non-standard port to access the GUI over HTTP. Changing this setting might require changing a Firefox configuration setting.
Web Interface HTTPS PortEnter a port number for an HTTPS connection to the web interface. This field allows configuring a non-standard port to access the GUI over HTTPS.
HTTPS ProtocolsSelect the Transport Layer Security (TLS) versions TrueNAS can use for connection security from the dropdown list. Cryptographic protocol for securing client/server connections.
Web Interface HTTP -> HTTPS RedirectSelect to redirect HTTP connections to HTTPS. A GUI SSL Certificate is required for HTTPS. Activating this also sets the HTTP Strict Transport Security (HSTS) maximum age to 31536000 seconds (one year). This means that after a browser connects to the web interface for the first time, the browser continues to use HTTPS and renews this setting every year.
Usage CollectionSelect to enable sending anonymous usage statistics to iXsystems. For more information about what usage data is collected, see the TrueNAS Data Collection Statement.
Show Console MessagesSelect to display console messages in real-time at the bottom of the browser.

PreferSelect when using highly accurate NTP servers such as those with time monitoring hardware. Only use for these highly accurate NTP servers.
Min PollEnter the minimum polling interval, in seconds, as a power of 2. For example, 6 means 2^6, or 64 seconds. The default is 6, and the minimum value is 4.
Max PollEnter the maximum polling interval, in seconds, as a power of 2. For example, 10 means 2^10, or 1,024 seconds. The default is 10, and the maximum value is 17.
