Advanced Platform Options

This Platform Administration window opens for controller platforms only, to enable, disable, or configure certain settings and properties.

For Windows-based hosts, you can use Windows “Remote Desktop Connections” for SFTP/SSH.

NOTE: This window replaces an FTP/Telnet selection available for QNX-based platforms running Niagara 4, which are both inherently less secure services.

This window contains these properties:

Property	Value	Description
SFTP/SSH Enabled Port	check box (defaults disabled: to no check mark)	Enables, disables, and configures SFTP (Secure File Transfer Protocol) or SSH (Secure Shell Protocol) access. For Windows-based hosts, you typically use Windows “Remote Desktop Connections” instead. As factory-shipped, a Niagara 4 controller’s SFTP and SSH services default to disabled. This may be best, especially if the platform is exposed to the public Internet. However, in some cases, you may wish to temporarily enable the single port shared by these services, perhaps to facilitate debugging. CAUTION: Even SFTP and SSH pose security risks. Before enabling, we strongly recommend you configure the platform TLS only, and keep this function disabled unless otherwise directed by Systems Engineering. After logging in with platform credentials, SSH access to a controller provides system shell access with the same menu as provided by serial shell access to its RS-232 port. You can change the TCP/IP port shared by these services from the well-known port to some other port. However, be sure that any firewalls used on your network allow traffic to the alternate port.
Daemon Debug Enabled	check box (defaults disabled: to no check mark)	Enables a QNX webserver to accept incoming browser connections on :3011 and :5011. Connecting to port 5011 using a browser (https://<ipAddress>:5011) provides a list of links to additional information about the QNX controller.
USB Backup Enabled	check box (defaults disabled: to no check mark)	Enables and disables USB backup for platforms that have USB backup capability.

Daemon Debug Enabled

check box (defaults disabled: to no check mark)

Enables a QNX webserver to accept incoming browser connections on :3011 and :5011.

Connecting to port 5011 using a browser (https://<ipAddress>:5011) provides a list of links to additional information about the QNX controller.

USB Backup Enabled

check box (defaults disabled: to no check mark)

Enables and disables USB backup for platforms that have USB backup capability.
