pertama kita lihat apakah network driver kita support untuk WOL:
budhi@budhi-PC:~$ sudo ethtool eth0
[sudo] password for budhi:
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Link partner advertised link modes: Not reported
Link partner advertised pause frame use: No
Link partner advertised auto-negotiation: No
Speed: 10Mb/s
Duplex: Half
Port: MII
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: pumbg
Wake-on: g
Current message level: 0x00000033 (51)
Link detected: no
budhi@budhi-PC:~$
terlihat bahwa network driver kita support pumbg untuk mengetahui pumbg apa liat di man ethtool
wol p|u|m|b|a|g|s|d...
Sets Wake-on-LAN options. Not all devices support this. The
argument to this option is a string of characters specifying
which options to enable.
p Wake on phy activity
u Wake on unicast messages
m Wake on multicast messages
b Wake on broadcast messages
a Wake on ARP
g Wake on MagicPacket(tm)
s Enable SecureOn(tm) password for MagicPacket(tm)
d Disable (wake on nothing). This option clears all previous
options.
untuk menset network kita agar bisa wol dengan MagicPacket berikut perintahnya
budhi@budhi-PC:~$ sudo ethtool -s eth0 wol g
seperti biasa agar perintah di atas di jalankan setiap restart atau booting kita
tambahkan script kecil di /etc/init.d/ beri nama script tersebut wol.sh
#!/bin/bash
ethtool -s eth0 wol g
buat menjadi executable
budhi@budhi-PC:/etc/init.d$ sudo chmod +x wol.sh
terakhir buat script tersebut run di setiap run level
budhi@budhi-PC:/etc/init.d$ sudo update-rc.d -f wol.sh defaults
update-rc.d: warning: /etc/init.d/wol.sh missing LSB information
update-rc.d: see
Adding system startup for /etc/init.d/wol.sh ...

/etc/rc4.d/S20wol.sh -> ../init.d/wol.sh
/etc/rc5.d/S20wol.sh -> ../init.d/wol.sh
finish sudah setting wol di linux
sekarang bagaimana caranya kita mengirim MagicPacket dari linux untuk itu
kita harus tahu mac address dari target
budhi@budhi-PC:~$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 40:61:86:e8:78:d4
perintah wakeonlan untuk mengirim MagicPacket
budhi@budhi-PC:~$ wakeonlan 40:61:86:e8:68:d4
Sending magic packet to 255.255.255.255:9 with 40:61:86:e8:68:d4
