The ftpd daemon should not be running. It gets started by inetd when an incoming ftp request arrives. The telnetd daemon gets started in the same manner. If you see it running it means someone (likely your self) is telnetted into the machine.
Try initiating an ftp connection to the QNX2 machine. Then check with ‘tsk’ to see if inetd starts the ftpd daemon.
It’s also worth trying to manually start it as maschoen said just to see if there are any errors (wrong file permissions, missing user accounts/directories etc).
