       upsd.conf - Configuration for Network UPS Tools upsd

       upsd uses this file to control access to	the server and set some	other
       miscellaneous configuration values. This	file contains details on
       access controls,	so keep	it secure. Ideally, only the upsd process
       should be able to read it.

       "MAXAGE seconds"
	   upsd	usually	allows a driver	to stop	responding for up to 15
	   seconds before declaring the	data "stale". If your driver takes a
	   very	long time to process updates but is otherwise operational, you
	   can use MAXAGE to make upsd wait longer.

	   Most	users should leave this	at the default value.

       "TRACKINGDELAY seconds"
	   When	instant	commands and variables setting status tracking is
	   enabled, status execution information are kept during this amount
	   of time, and	then cleaned up. This defaults to 3600 (1 hour).

       "STATEPATH path"
	   Tell	upsd to	look for the driver state sockets in path rather than
	   the default that was	compiled into the program.

       "LISTEN interface port"
	   Bind	a listening port to the	interface specified by its Internet
	   address or name. This may be	useful on hosts	with multiple
	   interfaces. You should not rely exclusively on this for security,
	   as it can be	subverted on many systems.

	   Optionally listen on	TCP port port instead of the default value
	   which was compiled into the code. This overrides any	value you may
	   have	set with configure --with-port.	If you don't change it with
	   configure or	this value, upsd will listen on	port 3493 for this

	   Multiple LISTEN addresses may be specified. The default is to bind
	   to	if no LISTEN addresses are specified (and ::1 if IPv6
	   support is compiled in).

	   To listen on	all available interfaces, you may also use for
	   IPv4	and and	:: for IPv6.

	       LISTEN myhostname.mydomain
	       LISTEN ::1
	       LISTEN 2001:0db8:1234:08d3:1319:8a2e:0370:7344

	   This	parameter will only be read at startup.	You'll need to restart
	   (rather than	reload)	upsd to	apply any changes made here.

       "MAXCONN	connections"
	   This	defaults to maximum number allowed on your system. Each	UPS,
	   each	LISTEN address and each	client count as	one connection.	If the
	   server runs out of connections, it will no longer accept new
	   incoming client connections.	Only set this if you know exactly what
	   you're doing.

       "CERTFILE certificate file"
	   When	compiled with SSL support with OpenSSL backend,	you can	enter
	   the certificate file	here. The certificates must be in PEM format
	   and must be sorted starting with the	subject's certificate (server
	   certificate), followed by intermediate CA certificates (if
	   applicable_ and the highest level (root) CA.	It should end with the
	   server key. See docs/security.txt or	the Security chapter of	NUT
	   user	manual for more	information on the SSL support in NUT.

       "CERTPATH certificate database"
	   When	compiled with SSL support with NSS backend, you	can enter the
	   certificate path here. Certificates are stored in a dedicated
	   database (data split	in 3 files). Specify the path of the database

       "CERTIDENT certificate name database password"
	   When	compiled with SSL support with NSS backend, you	can specify
	   the certificate name	to retrieve from database to authenticate
	   itself and the password required to access certificate related
	   private key.

       "CERTREQUEST certificate	request	level"
	   When	compiled with SSL support with NSS backend and client
	   certificate validation (disabled by default,	see
	   docs/security.txt), you can specify if upsd requests	or requires
	   client's' certificates. Possible values are :

	   o   0 to not	request	to clients to provide any certificate

	   o   1 to require to all clients a certificate

	   o   2 to require to all clients a valid certificate
