These scripts should save significant power by shutting down the Ethernet and USB ports.

A work around?
pkill ifplugd.agent
pkill net.agent
smsc95xx_up
Turns on the Ethernet and USB ports. Sets up networking.
echo 0x1 > /sys/devices/platform/bcm2708_usb/buspower
sleep 3
/sbin/ifconfig wlan0 down
echo "search domain_not_set.invalid
nameserver 166.102.165.11

/sbin/ifconfig wlan0 down
echo 0x0 > /sys/devices/platform/bcm2708_usb/buspower
sync_clock.sh
Syncs the clock. Called by cron and rc.local.
/home/hivetool/smsc95xx_up
timeout 20 /usr/sbin/ntpd -qg
/home/hivetool/smsc95xx_down
rc.local
- Turn off HDMI (saves about 20 ma.)
- Set the clock on boot up. (Note ntpd must be disabled.)
/opt/vc/bin/tvservice -off
timeout 60 /home/hivetool/sync_clock.sh
crontab
Syncs the clock four times a day. (1:07, 7:07, 13:07, and 19:07)
# Synch the clock
