View source for Gestione di un UPS in Debian con Nut

==Server con UPS collegato==
* Installazione software
 sudo aptitude install nut

<pre>
export UPS_NAME="apc_smartups_1500_rm"
export UPS_PASS="lapassword"
</pre>

=== Configurazione UPS APC USB ===
<pre>
cat | sudo tee /etc/nut/ups.conf > /dev/null <<EOFile
[$UPS_NAME]
    driver = usbhid-ups
    port = auto
EOFile
</pre>

===Per UPS APC Seriale===
<pre>
cat | sudo tee /etc/nut/ups.conf > /dev/null <<EOFile
[$UPS_NAME]
    driver = apcsmart
    port = /dev/ttyS0
EOFile
</pre>

* Aggiungere l'utente nut al gruppo dialout, per poter usare la seriale:
 sudo gpasswd -a nut dialout

=== Altri UPS===
Per altri modelli di UPS, vedi [http://www.networkupstools.org/compat/stable.html NUT hardware compatibility list]

* Avviare il demone per controllare il dialogo con l'UPS:
 sudo upsdrvctl start

 Network UPS Tools - UPS driver controller 2.2.2
 Network UPS Tools (version 2.2.2) - APC Smart protocol driver
         Driver version 1.99.8, command table version 2.0

* Configurare il demone:
<pre>
cat | sudo tee /etc/nut/upsd.conf > /dev/null <<EOFile
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32
ACCEPT localhost
REJECT all
EOFile
</pre>

* Configurare gli utenti e le password:
<pre>
cat | sudo tee /etc/nut/upsd.users > /dev/null <<EOFile
[local_mon]
    password = $UPS_PASS
    allowfrom = localhost
    upsmon master
EOFile
</pre>

* Configurare il monitor:

<pre>
cat | sudo tee /etc/nut/upsmon.conf > /dev/null <<EOFile
MONITOR ${UPS_NAME}@localhost 1 local_mon $UPS_PASS master
POWERDOWNFLAG /etc/killpower
SHUTDOWNCMD "/sbin/shutdown -h now"
EOFile
</pre>


* Sistemare le permission:
 sudo chown root:nut /etc/nut/*
 sudo chmod 640 /etc/nut/*

* Abilitare i demoni all'avvio:

 sudo perl -pi -e 's{^START_UPSD=no$}{START_UPSD=yes}' /etc/default/nut && \
 sudo perl -pi -e 's{^START_UPSMON=no$}{START_UPSMON=yes}' /etc/default/nut && \
 echo "18c0130bcd3a92f391c063bba30056f6  /etc/default/nut" | md5sum --check

* Riavviare il tutto:

 sudo invoke-rc.d nut  restart
 Restarting Network UPS Tools: upsdrvctl upsdrvctl upsd upsmon.

* Nei log:
 sudo tail -f /var/log/syslog

==Client Linux collegato in rete==

===Configurazione Accesso sul Server===

 export CLIENT_NAME="firemen"
 export CLIENT_DOM="cross.priv"
 export CLIENT_IP="192.168.0.254"
 export CLIENT_PASS="jeeR9ied"
 export UPS_NAME="apc_smartups_1500_rm"
 export UPS_SERVER="crosrv01.${CLIENT_DOM}"
 
* Configurare il demone:

 sudo sed -i'' -e"/^ACCEPT/i\ACL $CLIENT_NAME ${CLIENT_IP}/32" /etc/nut/upsd.conf

 sudo sed -i'' -e"/^REJECT/i\ACCEPT $CLIENT_NAME" /etc/nut/upsd.conf

A mano:

<pre>
cat | sudo tee /etc/nut/upsd.conf > /dev/null <<EOFile
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32
ACL $CLIENT_NAME ${CLIENT_IP}/32
ACCEPT localhost
ACCEPT $CLIENT_NAME
REJECT all
EOFile
</pre>

* Configurare gli utenti e le password:
<pre>
cat | sudo tee -a /etc/nut/upsd.users > /dev/null <<EOFile
[${CLIENT_NAME}]
    password = $CLIENT_PASS
    allowfrom = ${CLIENT_NAME}.$CLIENT_DOM
    upsmon master
EOFile
</pre>

 sudo invoke-rc.d nut restart

===Configurazione Client===
* Installare
 sudo aptitude install nut

* Configurare SOLO il monitor

<pre>
cat | sudo tee /etc/nut/upsmon.conf > /dev/null <<EOFile
MONITOR ${UPS_NAME}@${UPS_SERVER} 1 ${CLIENT_NAME} ${CLIENT_PASS} slave
POWERDOWNFLAG /etc/killpower
SHUTDOWNCMD "/sbin/shutdown -h now"
EOFile
</pre>

* Impostare l'autostart per il monitor:

 sudo perl -pi -e 's{^START_UPSMON=no$}{START_UPSMON=yes}' /etc/default/nut && \
 echo "702612de8e9e1a34c35cd7d4b05baf30  /etc/default/nut" | md5sum --check

O a mano:
 sudoedit /etc/default/nut

 ...
 START_UPSMON=yes
 ...

 
* Vedere se fa login:
 upsc -l $UPS_SERVER

* Vedere se legge i dati:
 upsc  ${UPS_NAME}@${UPS_SERVER}

* Riavviare
 sudo invoke-rc.d nut restart

==Client Windows collegato in rete==

* Installare da uno dei due siti
**http://csociety.ecn.purdue.edu/~delpha/winnut/
**http://code.google.com/p/winnut/

* Lanciare il TOOL
* Installare come servizio
* Editare la configurazione, aggiungendo la sola riga:
  MONITOR apc_smartups_620@server.host.dom 1 client_win PASSWORD_HERE slave
