cron is one of the oldest of Unix utilities, found on all modern variants today. It's a scheduler. It schedules things. cron reads a crontab - a dedicated file defining what should be run, when to run it, how often it should be re run after that etc. If you don't have script writing skills, you can have crontab schedule the ifconfig (card) up/down commands directly. Running a "crontab -l" will list the current user's crontab. The simplest way for me to explain changing a crontab is - log on as the account who's crontab you wish to modify (i.e. the account who has the access to run the commands you want) and run "crontab -e". This will launch the default text editor and allow you to start modifying that account's crontab file. The crontab file has a specific format, which is documented at http://en.wikipedia.org/wiki/Cron#Operators. If you've never used cron before, I'd recommend reading that whole page. If that doesn't get you out of trouble here are some examples: To run a 'ifconfig (card) down' at 3pm and a 'ifconfig (card) up' at 5pm, add the following two line's to root's crontab: 0 15 * * * ifconfig (card) down 0 17 * * * ifconfig (card) up Of course, replace (card) with the name of the NIC you actually want to take down/up. If you only want to perform those commands on card called e1000g0, and only on weekdays (Monday to Friday), then add these to root's crontab: 0 15 1-5 * * ifconfig e1000g0 down 0 17 1-5 * * ifconfig e1000g0 up Running "man cron" and "man crontab" will give you further information as well.
