Next, you will need to configure three four files in /etc/ups: ups.conf, upsd.users, hosts.conf, and upsmon.conf. They will look almost identical to Selinger's:
{{Code|Code=
vi /etc/ups/ups.conf
password = password2
upsmon master
}}
{{Code|Code=
vi /etc/ups/hosts.conf
}}
{{Text|Text=
MONITOR apc@localhost "UPS on HDA"
}}
