Der momentane Zustand bei meiner Karte f\u00fcr ETH0 ist der Zeile Support Wake-on: g<\/em> zu entnehmen. Das kleine g<\/em> steht f\u00fcr Wake on MagicPacket ™<\/em> – siehe man<\/em> page zum ethtool<\/em>.<\/p>\n
Das setzt man einmal h\u00e4ndisch mit<\/p>\n
sudo ethtool -s eth0 wol g<\/p><\/blockquote>\n
und tr\u00e4gt diese Zeile ohne sudo<\/em> auch in die \/etc\/rc.local<\/em> vor dem exit 0<\/em> ein.<\/p>\n
In die \/etc\/init.d\/halt<\/em> kommt noch ein<\/p>\n
NETDOWN=no<\/p><\/blockquote>\n
statt des vorhandenen yes<\/em>, damit die Karte nicht abgeschaltet wird, wenn der Rechner runter f\u00e4hrt.<\/p>\n
Man notiert sich nun die MAC Adresse der ETH0 (ifconfig eth0<\/em>) und ein shutdown -h<\/em> knippst den Rechner aus … Jetzt kann man testen, ob man dieses Ger\u00e4t auch wieder \u00fcber’s Netz wach bekommt. Hierzu ben\u00f6tigt man das Paket etherwake<\/em><\/p>\n
sudo apt-get install etherwake<\/p><\/blockquote>\n
Ein WOL Paket auf die MAC 00:30:05:83:0d:74 wird gesendet mit<\/p>\n
sudo etherwake 00:30:05:83:0d:74<\/p><\/blockquote>\n
… und dann kann man mit Hoffen beginnen. Oder mit debuggen. Je nach Netzwerkkarte.<\/p>\n
Wenn es funktioniert, dann kann man sich einen Alias in der .bashrc<\/em> oder .bash_aliases<\/em> hierzu anlegen, der einem das Memory zur MAC Adresse abnimmt<\/p>\n
alias fscon=’sudo etherwake 00:30:05:83:0d:74′<\/p><\/blockquote>\n
Wer \u00fcber einen WLAN AP oder das Internet WOL Pakete versenden will, kann Pech haben – diese k\u00f6nnen nicht \u00fcber jedes Ger\u00e4t geroutet werden. Router, die directed broadcasts<\/em> unterst\u00fctzen, k\u00f6nnen aber entsprechend konfiguriert werden.<\/p>\n
Ein Script f\u00e4hrt nun unseren Backup-\/Spiele-\/Tauschordner-Server am sp\u00e4ten Abend runter – und ein Befehl holt diesen wieder her, wenn er gebraucht wird. Ist schon vor dem sp\u00e4ten Abend klar, dass er ausgeschaltet werden kann, dann hilft eine alias<\/em> Definition in der .bashrc<\/em> weiter:<\/p>\n
alias fscoff=’ssh -t benutzer@192.168.0.112 „sudo shutdown -h now“‚<\/p><\/blockquote>\n
Man wird dann zwei mal nach dem Passwort gefragt – einmal f\u00fcr SSH und dann noch f\u00fcr das sudo. Das k\u00f6nnen nun auch die Kinder, mit diesen beiden Aliasen umgehen: fscon<\/em> schaltet die Kiste ein – fscoff<\/em> schaltet sie wieder ab. Und vom gesparten Strom gehen wir essen.<\/p>\n","protected":false},"excerpt":{"rendered":"
