The File Transfer Protocol (FTP) is a simple option for data transfers. The SSH options provide secure transfer methods for critical objects like configuration files, while the Trivial FTP options provide simple file transfer methods for non-critical files.
Options for configuring FTP, SSH, and TFTP are in System > Services. Click the edit to configure the related service.
FTP requires a new dataset and a local user account.

The FTP service has basic and advanced setting options. Click the edit for FTP to open the Basic Settings configuration screen.
To configure FTP, go to System > Services and find FTP, then click edit.
The iSCSI screen displays settings to configure iSCSI block shares.
Internet Small Computer Systems Interface (iSCSI) represents standards for using Internet-based protocols for linking binary data storage device aggregations. IBM and Cisco submitted the draft standards in March 2000. Since then, iSCSI has seen widespread adoption into enterprise IT environments.
iSCSI functions through encapsulation. The Open Systems Interconnection Model (OSI) encapsulates SCSI commands and storage data within the session stack. The OSI further encapsulates the session stack within the transport stack, the transport stack within the network stack, and the network stack within the data stack. Transmitting data this way permits block-level access to storage devices over LANs, WANs, and even the Internet itself (although performance clould suffer if your data traffic is traversing the Internet).
The Services > NFS configuration screen displays settings to customize the TrueNAS NFS service.
Go to System > Services screen, locate NFS and click edit to open the screen, or use the Config Service option on the Unix (NFS) Share widget options menu found on the main Sharing screen.
Select Start Automatically to activate the NFS service when TrueNAS boots.
We recommend using the default NFS settings unless you require specific settings.
The System > Services screen includes two icons on the NFS service row:
The UDP protocol is deprecated and not supported with NFS. It is disabled by default in the Linux kernel. Using UDP over NFS on modern networks (1Gb+) can lead to data corruption caused by fragmentation during high loads.
S.M.A.R.T.
Note that the table(s) below can be reorganized by clicking on the column titles. This allows you to reorganize the information in each column by togglnig between a descending and ascending order.
S.M.A.R.T. Service Screen
The Services > S.M.A.R.T. screen displays settings to configure when S.M.A.R.T. tests run and when to trigger alert warnings and send emails.
Name Description Check Interval Enter the time in minutes for smartd to wake up and check if any tests are configured to run. Power Mode Select the power mode from the dropdown list. Options are Never, Sleep, Standby or Idle. S.M.A.R.T. only tests when the Power Mode is Never. Difference Enter a number of degrees in Celsius. S.M.A.R.T. reports if a drive temperature changes by N degrees Celsius since the last report. Informational Enter a threshold temperature in Celsius. S.M.A.R.T. sends a message with a LOG_INFO log level if the temperature is above the threshold. Critical Enter a threshold temperature in Celsius. S.M.A.R.T. sends a message with a LOG_CRIT log level and send an email if the temperature is above the threshold. Click Save after changing any settings.
Services
TrueNAS Enterprise
System > Services displays each system component that runs continuously in the background. These typically control data-sharing or other external access to the system. Individual services have configuration screens and activation toggles, and you can set them to run automatically.

The Configure icon opens the service configuration screen.
The NFS service row has one additional NFS Sessions icon that opens the NFS Sessions screen.
SMB
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 > 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.
