 1 | # pi-wol
 2 | 
 3 | It’s the hail Mary of wake on lan commands for my raspberry pi / pi zero.
 4 | 
 5 | I use this to ping my servers and wake them up if they are off.  They should never be.
 6 | 
 7 | ## install
 8 | 
 9 | `sudo apt-get install etherwake`
10 | 
11 | `sudo apt-get install wakeonlan`
12 | 
13 | ## cron job
14 | 
15 | `crontab -e`
16 | 
17 | `@hourly bash /home/pi/power-on-server.sh > power-on-server.log`
18 | (will run at reboot and will pipe out logs)
19 | 
20 | Requires `etherwake` and `wakeonlan` (apt-get).
21 | 
22 | Installed `etherwake` and `wakeonlan` beacuse I had some issues with one or the other between updates, so I added both so that I don't have to worry when updating.
