hosts.conf: Access control for Network UPS Tools CGI programs
hosts.conf - Access control for Network UPS Tools CGI programs
The CGI programs (upsset.cgi(8), upsstats.cgi(8), upsimage.cgi(8)) use this file to determine if they are allowed to talk to a host. This keeps random visitors from using your web server to annoy others by creating outgoing connections.
MONITOR ups description
element is in the form
upsname[@hostname[:port]]. To allow connections to a UPS called "snoopy" on a system called "doghouse" that runs upsd on port 7877, it would look like this:
MONITOR snoopy [at] doghouse:7877 "Joe Cool"
The description must be one element, so if it has spaces, then it must be wrapped with quotes as shown above. The default hostname is "localhost".
