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.

MONITORupsdescription The ups element is in the form upsname[@hostname[:port]]. To allow connections to an UPS called "snoopy" on a system called "doghouse" that runs upsd on port 7877, it would look like this: MONITOR snoopy@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".

• Contents of this file should be pure ASCII (character codes not in range would be ignored with a warning message). • This file does not contain passwords. Read-only monitoring in NUT is anonymous, and the upsset(8) program asks for credentials in the browser session when commanding a particular UPS (web-server should be secured, as reported to the program by upsset.conf(5) file).
