I would like to verify my understanding keeping in mind I have a one master and one slave computer. When the master gets the low batt/noAC signal it initiates a broadcast packet(s) on port 3493. 1) Is this correct? Then the slave computer must have this port open and it listens on this port for the shut-down command. 2) Is this correct? On the slave if I run the following: steve@MyDesktop:~$ nmap -p 3493 192.168.0.6 Starting Nmap 6.40 ( http://nmap.org ) at 2014-11-09 15:42 ESTNmap scan report for 192.168.0.6Host is up (0.00013s latency).PORT STATE SERVICE3493/tcp closed nut Nmap done: 1 IP address (1 host up) scanned in 11.06 seconds Which tells me this port is configured for nut but it is closed? I have rebooting and starting and stopping the service using: sudo service ups-monitor stop sudo service ups-monitor startBut it remains closed. 3) Assuming this should be open how do I fix this?
Thank you for any help - Steve
