===Variables et commandes ASI===
Dans certains cas, vous souhaiterez peut-être modifier les variables de l'onduleur lui-même, telles que le paramètre Low Charge/LOWBATTERY. Cela nécessite l'utilisation de la commande '''upsrw''' et les privilèges d'administrateur ASI.
Vous souhaiterez peut-être également contrôler l'onduleur directement à partir de la ligne de commande en émettant des commandes ASI. Cela nécessite l'utilisation de la commande '''upscmd''' et les privilèges d'administrateur ASI.
{{Warning box|type=Attention : |en général, les données de l'onduleur doivent rester protégées et les modifications ou l'émission de commandes doivent être effectuées avec attention. Si vous souhaitez apporter des modifications aux données ou émettre des commandes, les privilèges d'administrateur peuvent être activés comme ci-dessous et doivent ensuite être désactivés.}}

Vous devriez vérifier votre nouveau mot de passe (AdminPass) pour exécuter '''upsrw''' et '''upscmd'''. Bien sûr, vous pouvez changer votre mot de passe pour un mot de passe plus facile à utiliser.
config show nut
Pour mettre un nouveau mot de passe admin dans la base de données (le nouveau mot de passe étant « admin » (à modifier selon vos souhaits) :
config setprop nut AdminPass admin
Pour activer les privilèges d'administration et passer une commande à l'ASI :
config setprop nut AdminUser enabled
Maintenant, pour que '''upsd''' reconnaisse la modification de l'administrateur pour les privilèges d'administration, nous développons le modèle et rechargeons la configuration '''upsd''' :
/sbin/e-smith/expand-template /etc/ups/upsd.users
/usr/sbin/upsd -c reload

In order to be able to use '''upsrw''' and '''upscmd''' it is necessary to have a suitable additional user defined in the '''upsd.users''' configuration file.
In order to create a suitable user we will use SME Servers templating system and configuration database. This is based on an original forum thread[http://forums.contribs.org/index.php?topic=40668.0].
First we need to create a suitable custom template directory
mkdir -p /etc/e-smith/templates-custom/etc/ups/upsd.users
cd /etc/e-smith/templates-custom/etc/ups/upsd.users
Create and edit a new file called 'admin' with the following content:
{
# create admin user for upsd to allow setting of
# UPS parameters via upsrw
$OUT .= "";
return unless (($nut{AdminUser} || 'disabled') eq 'enabled');
return unless (($nut{AdminPass} || <nowiki>''</nowiki>) ne <nowiki>''</nowiki>);
$OUT .= "\n";
$OUT .= " [admin]\n";
$OUT .= " password = $nut{AdminPass}\n";
if ( ($nut{Master} || 'yes') ne 'no') {
$OUT .= " allowfrom = localhost\n";
} else {
$OUT .= " allowfrom = localhost localnet\n";
}
$OUT .= " actions = set\n";
$OUT .= " instcmds = all\n";
}
Create two new database properties for nut
config setprop nut AdminUser enabled (This enables the creation of the user in the template above)
config setprop nut AdminPass admin (This sets a password for the admin user. Set to whatever you want)
Now, to get '''upsd''' to recognise the new user with the required administrative privileges we expand the template and reload the '''upsd''' configuration
/sbin/e-smith/expand-template /etc/ups/upsd.users
/usr/sbin/upsd -c reload
{{Note box|To disabled the admin user once you have changed the UPS parameters or issued commands as required, issue the commands
config setprop nut AdminUser disabled

===Usage of Nut-cgi Scripts===
Now go to http://yourdomain.tld/nut to see the statistics and information for the UPS at localhost.
By editing <tt>/etc/ups/hosts.conf</tt> and adding additional network UPS details, nut-cgi can be used to monitor more than one UPS. By the modification above, only the localhost is monitored.
=Additional Information=
There are template fragments in /etc/e-smith/templates/etc/ups that control the config files located in /etc/ups. The default settings should be OK for most situations. The <tt>/etc/nut.conf</tt> file must be manually edited like <tt>mode=standalone</tt> as the templates do not touch this file. In this case it would be:
sed -e 's/^MODE.*/MODE=standalone/' -i /etc/ups/nut.conf
By default, NUT is configured for a USB connected UPS in Master mode, but is disabled. When enabled, NUT will monitor the UPS and take various actions when certain notifications are received. This is controlled by the '''/etc/ups/upsmon.conf''' file which among other things lists the notifications and the actions to be taken for each. For example an ''On Battery'' event is captured by the '''NOTIFYFLAG ONBATT''' entry and the following '''SYSLOG+WALL+EXEC''' command string. This string tells '''upsmon''' to write the event to the System Log, broadcast a message to all users via Wall, and execute the command denoted by the '''NOTIFYCMD''' entry.
SME Server sets the '''NOTIFYCMD''' to '''/sbin/e-smith/nutUPS.notify''', and this executable file simply sends an email to the SME admin user with a notification of the event.
Apart from the various events that the UPS and '''upsmon''' may notify via the '''NOTIFYFLAGS''' a ''Low Battery'' event will automatically and immediately cause '''upsmon''' to issue the '''SHUTDOWNCMD''' as defined in '''upsmon.conf''' (signal-event halt) and set a flag '''POWERDOWNFLAG''' so it knows on future restart that it is a UPS recovery.
For information on configuration parameters:
man ups.conf
man upsd.conf
man upsd.users
man upsmon.conf
man upssched.conf
For general information:
man upsd
man nutupsdrv
==Timeout Issues==
If you have comms problems like this you can add a custom timeout:
"USBDEVFS_CONTROL failed cmd blazer_usb rqt 33 rq 9 len 8 ret -110"
Add a new config item. The default is 2
config setprop nut pollInterval 4
Modify the template
mkdir -p /etc/e-smith/templates-custom/etc/ups/ups.conf
cp /etc/e-smith/templates/etc/ups/ups.conf/UPS /etc/e-smith/templates-custom/etc/ups/ups.conf/UPS
nano /etc/e-smith/templates-custom/etc/ups/ups.conf/UPS
Add the bits between the # comments
{
my $model = $nut{Model} || "usbhid-ups";
my $device = $nut{Device} || "/var/lib/ups/hiddev0";
my $type = $nut{Type};
my $mfr = $nut{mfr};
my $mdl = $nut{mdl};
# Add this
my $poll = $nut{pollInterval} || '2';
if ($poll ne '2') {
$OUT .= "pollinterval = $poll\n";
}
# ends here
$OUT .= "[UPS]\n";
$OUT .= "\tdriver = $model\n";
expand-template /etc/ups/ups.conf
cat /etc/ups/ups.conf
You should see something like this:
# Copyright (C) 1999-2006 Mitel Networks Corporation
#------------------------------------------------------------
pollinterval = 4
[UPS]
Restart nut
service nut restart
Now check to see the correct timeout:
upsc UPS | grep driver.parameter.pollinterval
driver.parameter.pollinterval: 4
To reset either delete the key, or set it to the default of 2
==Further reading==
The NUT website is here: [http://www.networkupstools.org/ NUT]
From the above references you can glean which configuration setting does what function, etc.
If you want to modify the operation of NUT from the standard configuration, then you should generally modify the NUT config files by creating custom templates, expanding the templates and restarting service. This will ensure modifications survive a future reboot or reconfiguration.
An example of doing this can be found in the forum [http://forums.contribs.org/index.php?topic=40668.0] and in the section above for UPS Administrative Privileges
