Hi and sorry my english.

You don't need to use dhcp and fix mac<->ip table (/etc/ethers).
You can use other MAC conf file to list computer (/opt/etc/wakeuplist.conf ).
Save MACs and computers info ("00:11:22:33:44:55 MyComputer") to your config file (/opt/etc/wakeuplist.conf) and change "/etc/ethers" with "/opt/etc/wakeuplist.conf" in scripts.

Code:
...
awk -f wol.awk /etc/ethers "ethlist" >ethlist.$$
...
change to
Code:
awk -f wol.awk /opt/etc/wakeuplist.conf "ethlist" >ethlist.$$
Good luck to work, bye.
