Disable networking for a set period of time?

[gazer22]

In pursuit of productivity...

Does anyone know a way to disable all network/internet access for a given amount of time? Preferably reversible (during that period of time) only through something drastic like a reboot.

Example usage:
running get_to_work.sh would turn off my network/internet access for two hours. After two hours, the network would start working again. Prior to two hours, the only way to get networking back would be to do a re-boot.

Yes, the purpose is to prevent myself from surfing the 'net when I should be getting some work done on the local machine...

you could just do

sudo ifconfig eth0 down

Then when you have finished your work

sudo ifconfig eth0 up

You could put this in a script with a cron job or something but I would just do it manually if it was me.

Thanks -

That'll definitely work. Now I'm thinking of some sort of daemon that can monitor eht0 and pull it down...

Scheduling via "at" may be a good idea too.
