You're right, and I have no idea how I missed that the first time. The dangers

Umm, the ups -c option "Lists each client connected on ups, one name per
line." according to the man page and it has worked for me for a long time.

To be pedantic for a moment, the TCP connections to port 3493 are a superset of 
the slaves connected - the difference being tools that are monitoring but not 
logged in as a slave.

You can get a list of slaves with the following:

echo 'LIST CLIENT ups' | nc nut-server-host 3493

I thought there was an option to "upsc" for this, but I guess not. There is 
also a bug in the Python module:

if there is no such command in NUT, then on my Debian Stretch using the lsof -p 
command on the upsd proccess on my NUT server reveals TCP connections to the 
clients.


I see 2 connections pr. client, probably because each client monitors 2 UPS's, 
one for each powersupply.

[Nut-upsuser] List of connected slaves

[zefanjas]

Hi,

is there a command to get a list of connected slaves you can run on the
nutserver? I want to monitor the slaves and if their are actually
connected to server.
