Are you attempting to run the agent on a machine *without*
the ups comm connected to it, such that it will receive status
from the server that does have it connected and shutdown when
that remote agent that *is* monitoring the ups suggests it should?

I don't think so, I think your ups is connected to the server
that is running the agent. You need not add this port to the
firewall. It talks to itself over the loopback adapter.

Group? Below your gui correctly identifies that data field as
the pid:)

>The status field of the Service Configuration GUI says:
>apcupsd (pid 2419) is running...
>Error contacting host localhost port 3551: Connection refused

You have suggested the NETSERVER directive be off, but you want
a client side app to communicate with it:) Turn that "on" and
restart it.
