npm install wake_on_lan --save # use the library
npm install wake_on_lan -g # optional global wake utility To wake a machine with a given mac address do:
var wol = require('wake_on_lan');
wol.wake('20:DE:20:DE:20:DE');
wol.wake('20:DE:20:DE:20:DE', function(error) {
if (error) {
// handle error
} else {
// done sending packets
}
});
var magic_packet = wol.createMagicPacket('20:DE:20:DE:20:DE');See windows notes and the wake utility.
MAC addresses are strings and may use any separator or no separator at all:
'20:DE:20:DE:20:DE'
'20-DE-20-DE-20-DE'
'20DE20DE20DE'wake(mac, [options, callback])
Send a sequence of Wake-on-LAN magic packets to the given MAC address. The callback is called when all packets have been sent or an error occurs. The options object may have the following properties:
| Property | Description | Type | Default |
|---|---|---|---|
address |
The destination address | String | 255.255.255.255 |
num_packets |
The number of packets to send | Number | 3 |
interval |
The interval between packets in milliseconds | Number | 100 |
port |
The destination port to send to | Number | 9 |
createMagicPacket(mac)
Returns a buffer with a magic packet for the given MAC address.
wake [options] MAC
| Option | Short | Description | Default |
|---|---|---|---|
| --address | -a | Broadcast address, ipv4 or ipv6 | 255.255.255.255 |
| --num_packets | -n | Number of packets to send | 3 |
| --interval | -i | Interval between each packet | 100 |
| --port | -p | UDP port of the target destination | 9 |
| --help | -h | Show help |
wake 20:DE:20:DE:20:DE
wake -a 192.168.1.255 20-DE-20-DE-20-DE
wake --num_packets 10 --interval 50 -p 9 20DE20DE20DEBecause windows routes global broadcasts differently from unix systems, it is necessary to specify a broadcast address manually, e.g:
wol.wake(someMac, { address: "192.168.2.255" }, wakeCallback);
Use os.networkInterfaces() to calculate the broadcast address dynamically. See @mwittig's comment for further information.
