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:
