TrueNAS has numerous settings contained inside System > General. These allow a wide range of system customization, from changing the web interface address, localization options, and data collection to SED, console, and storage options.

System General

GUI

NameDescription
GUI SSL CertificateThe system uses a self-signed certificate to enable encrypted web interface connections. To change the default certificate, select a different certificate that was created or imported in the Certificates menu.
Web Interface IPv4 AddressChoose a recent IP address 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 IPv6 AddressChoose a recent IPv6 address 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 PortAllow configuring a non-standard port to access the GUI over HTTP. Changing this setting might require changing a Firefox configuration setting.
Web Interface HTTPS PortAllow configuring a non-standard port to access the GUI over HTTPS.
HTTPS ProtocolsCryptographic protocols for securing client/server connections. Select which Transport Layer Security (TLS) versions TrueNAS can use for connection security.
Web Interface HTTP -> HTTPS RedirectRedirect 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.

Localization

NameDescription
LanguageSelect a language from the drop-down menu.
Date FormatChoose a date format.
Console Keyboard MapSelect a keyboard layout.
TimezoneSelect a time zone.
Time FormatChoose a time format.

Other Options

NameDescription
Crash reportingSend failed HTTP request data which can include client and server IP addresses, failed method call tracebacks, and middleware log file contents to iXsystems.
Usage collectionEnable sending anonymous usage statistics to iXsystems.

After making any changes, click SAVE. Changes to any of the web interface fields can interrupt web interface connectivity while the new settings are applied.

This screen also contains these buttons:

Saves a backup copy of the current configuration database in the format hostname-version-architecture. This file is downloaded to the computer accessing the web interface. Saving the configuration after making any configuration changes is highly recommended.

See System Config Backups for more details about backing up the system configuration.

Changes the system configuration settings. Browse to a previously saved configuration file to restore that configuration.

This can cause unexpected changes to system settings. Investigate both the current system settings and the settings stored in the other configuration file before uploading a config file to TrueNAS.
Reset the configuration database to the default base version. This does not delete user SSH keys or any other data stored in a user home directory. Since configuration changes stored in the configuration database are erased, this option is useful when correcting mistakes or returning a test system to the original configuration.
