FTP/Telnet

This Platform Administration view selection is available for QNX-based JACE only. (For Windows-based platforms, you configure/enable FTP and Telnet within local Windows TCP/IP configuration.)

As factory-shipped, a QNX-based JACE has the FTP and Telnet service 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 one or both services, perhaps to facilitate debugging.

CautionFTP and Telnet pose security risks. We strongly recommend you keep each one disabled, unless otherwise directed by Systems Engineering.

Note that Telnet access to a QNX-based JACE provides “system shell” access, providing (after login using platform credentials) the same menu as “serial shell access” to its RS-232 port. For related details, see the “System shell” section in the JACE NiagaraAX Install & Startup Guide.

You can also change the TCP/IP port used by each service from the “well-known” port to some other port. However, be sure that any firewalls being used on your network will allow traffic to that port.

Figure 57 shows the FTP and Telnet dialog with Telnet enabled (both services showing “well-known” ports).
