Taking a system off a network on a system

say i have a system on thats on a network with access to the internet.

now, i have sensitive information on this system and i do not want the system to be connected to the outside world anymore. how do i get it off the network without actually having to disconnect the cables?

i'm asking this because i need advanced answers. i believe ifconfig le0 down can do the job but are there any other more sophiscated commands that can be used to accomplish this?

Network configuration varies from version to version of linux but you should still be able to achieve the same results with some command line commands.

You could try:

Code:
route del default # this removes the default gateway of the machine
/etc/init.d/network stop # this stops all network interface on the machine

Depending on your version of linux you could also modify the iptables file and block all TCP/UDP traffic outbound/inbound on a given network interface.

That 3-word command accomplishes the goal, why make it more complicated?
