it is required on daily basis.... now my OS is U9.10
Installed U9.10 beta yesterday..... it has better management for changing run level comparing to U9.04 still not checked fully./

Create a cron entry for root that runs at 0800
(man cron or man crontab or google for how to use cron to see how)

One command to stop eth0 is
ifconfig eth0 down

Or alternatively you could
/etc/init.d/network stop
which would take all networking down

You might also need a cron entry to start it again that runs
/etc/init.d/network restart
