# HOSTS.CONF(5)

## NAME

hosts.conf - Access control for Network UPS Tools CGI programs

## DESCRIPTION

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.

## IMPORTANT NOTES

- 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).

## DIRECTIVES

MONITOR ups description

  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".

CUSTOM_TEMPLATE_LIST filename
CUSTOM_TEMPLATE_SINGLE filename

  upsstats(8) allows to use custom HTML template files for some of its outputs (JSON and "treemode" mark-ups are currently hard-coded in the binary), which you can specify in the query string part of the URI (in your `index.html` and/or added cells of `header.html`) as e.g.

    .../cgi-bin/upsstats.cgi?template_single=custom-s.htm&template_list=custom-l.htm

+ Specific file names for a specific role must be permitted with these directives (can be repeated). File names must contain the `.htm` sub-string and must be located directly in the NUT configuration directory (same as default templates). If custom templates are used in the original request URI, they will be automatically suffixed to generated links (primarily `HOSTLINK`, but also just in case added to `TREELINK` and `TREELINK_JSON`, see upsstats.html(5) for more details).
