"Connection refused" is a standard network error message that says that either a firewall is blocking the port, or no daemon is currently listening on that port. Since both ends of this connection are on the same host, a firewall is not particularly likely to be blocking this, but you could always change it to use 127.0.0.1 (localhost) if there is a firewall that can't easily be changed. In the case of the client Pi, you mentioned that ups.conf was originally empty. You may need to restart upsd (sudo "service nut-server restart", I think) now that it has an entry for the locally connected UPS. upsd listens on the port that NUT clients like upsmon and upsc connect to. - Charles _______________________________________________ Nut-upsuser mailing list Nut-upsuser@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
