Under construction More information on how to use wake-on-lan to startup your mythbox will follow shortly...
If you have a network card that supports wake-on-lan, you can powerup your mythbox by sending it a 'magic packet' over the network. Here's what i did:
First, find out whether your network card supports wol:
# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 1 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000001 (1) Link detected: yes
The 'g' in Supports Wake-on: pumbg indicates that wake-on-lan by using a 'magic packet' is indeed supported. Next, you need to make sure that wake-on-lan support is enabled in the BIOS (although, this does not seem to be necessary on my Epia M10000). In addition, you need to tell your network card to enable wake-on-lan:
# ethtool -s eth0 wol g
Since after rebooting Wake-on will be reset, you might what to add it to /etc/rc.local:
# echo 'ethtool -s eth0 wol g' >> /etc/rc.local
Now turn off you mythbox and send it a 'magic packet'.
Sending 'magic packet' to wake up mythbox
You will need a wake-on-lan client to send 'magic packets' over your network. Also, you need to known the MAC address of the machine you what to poweron:
