<h3>WOL</h3>
|
|
|
|
Defines a WOL device via its MAC and IP address.<br><br>
|
|
|
|
when sending the <b>on</b> command to a WOL device it wakes up the dependent device by sending a magic packet. When running in repeat mode the magic packet ist sent every n seconds to the device.
|
|
So, for example a Buffalo NAS can be kept awake.

<b><font size="+1">Notes</font></b>:
|

|
|
Not every hardware is able to wake up other devices by default. Often firewalls filter magic packets and have to be configured accordingly.
|
|
You may need a packet sniffer to check some malfunction.

<h4>Attributes</h4>

<li><code>attr <name> sysCmd <string></code>
|
|
<br>Custom command executed to wakeup a remote machine, i.e. <code>/usr/bin/ether-wake or /usr/bin/wakeonlan</code></li>
|
|
<li><code>attr <name> shutdownCmd <command></code>
|
|
<br>Custom command executed to shutdown a remote machine. You can use <command>, like you use it in at, notify or Watchdog</li>
|
|
<br><br>
|
|
Examples:
|
|
<PRE>
|
|
attr wol shutdownCmd set lamp on # fhem command
|
|
attr wol shutdownCmd { Log 1, "Teatime" } # Perl command
|
|
attr wol shutdownCmd "/bin/echo "Teatime" > /dev/console" # shell command
|
|
</PRE>
|
|
<li><code>attr <name> interval <seconds></code></a>
|
|
<br>defines the time between two checks by a <i>ping</i> if state of <name> is <i>on</i>. By using 0 as parameter for interval you can switch off checking the device.</li>
|
|
<li><code>attr <name> useUdpBroadcast <broadcastAdress></code>
|
|
<br>When using UDP then the magic packet can be send to one of the broadcastAdresses (x.x.x.255, x.x.255.255, x.255.255.255) instead of the target host address.
|
|
Try using this, when you want to wake up a machine in your own subnet and the wakekup with the target adress is instable or doesn't work.</li>

<h3>WOL</h3>
|
|
|
|
Definiert ein WOL Gerät über seine MAC und IP Addresse.<br><br>
|
|
|
|
Wenn der <b>on</b> Befehl an das WOL Gerät gesendet wird, wird das entsprechende Gerät durch das Senden eines "magic packet" aufgeweckt. Wenn WOL im repeat Modus läuft, wird das "magic packet" alle n Sekunden zum Gerät geschickt.
|
|
So kann z.B. ein Buffalo NAS "wach" gehalten werden.
|
|

<b><font size="+1">Anmerkungen</font></b>:
|
|
<ul>
|
|
Nicht jede Hardware kann standardmäßig andere Geräte aufwecken. Firewalls filtern häufig magic packets und müssen entsprechend konfiguriert werden.
|
|
Möglicherweise ist ein Packet Sniffer notwendig um Fehlfunktionen zu überprüfen.

<h4>Set </h4>

<ul>

<code><b><font size="+1">set <name> <value></font></b></code>
|

<br><br>
|

wobei <code>value</code> einer der folgenden ist:<br>
|
|
<pre>
|
|
<b>refresh</b> # überprüft (mittels ping) ob das Gerät gerade läuft
|
|
<b>on</b> # schickt ein magic packet an die definierte MAC-Adresse
|
|
<b>off</b> # beemdet das Senden von magic packets schickt das <b>shutdownCmd</b>(siehe Attribute)

<code>set computer1 on</code><br>

<h4>Attribute</h4>
|
|
<ul>
|
|
<li><code>attr <name> sysCmd <string></code>
|
|
<br>Eigener Befehl, um ein entferntes Gerät aufzuwecken, z.B. <code>/usr/bin/ether-wake or /usr/bin/wakeonlan</code></li>
|
|
<li><code>attr <name> shutdownCmd <command></code>
|
|
<br>Eigener Befehl, um ein entferntes Gerät herunter zu fahren. Es können <command>, wie in at, notify oder Watchdog verwendet werden</li>
|
|
<br><br>
|
|
Beispiele:
|
|
<PRE>
|
|
attr wol shutdownCmd set lamp on # fhem Befehl
|
|
attr wol shutdownCmd { Log 1, "Teatime" } # Perl Befehl
|
|
attr wol shutdownCmd "/bin/echo "Teatime" > /dev/console" # shell Befehl
|
|
</PRE>
|
|
<li><code>attr <name> interval <seconds></code></a>
|
|
<br>definiert die Zeit zwischen zwei Checks mittels <i>ping</i> Wenn der state von <name> <i>on</i> ist. Mit dem Wert 0 als interval wird die regelmäßige Überprüfung abgeschaltet.</li>
|
|
<li><code>attr <name> useUdpBroadcast <broadcastAdress></code>
|
|
<br>Bei der Nutzung von UDP kann das magic packet an eine det broadcastAdressen (x.x.x.255, x.x.255.255, x.255.255.255) geschickt werden, an Stelle des Ziel-Hosts address.
|
|
Diese Methode sollte verwendet werden, wenn ein Gerät im eigenen Subnetz aufgeweckt werden soll, aber der wakeup mit dem Zielhost nicht funktioniert oder nicht stabil ist.</li>
