How To: Silently Setup VPN on 10.6 & 10.7


The below is hugely plagarised from a script posted by Mark Bolwell to the Mac Enterprise list.

I use a version of the below in my Casper Imaging workflow to configure the a VPN Cisco IPSec network connection. As i run it at Imaging time i’ve added some logic so it only runs on MacBook models (which you may wish to remove).

How To: Turn off Wireless Card


We run the following on all macs with a wireless card as a offline policy via Casper at logout.

This script will:

  1. Enable the wireless service if it’s not been enabled.
  2. Clear any set DNS servers & search domains (can be turned off for 10.4, reasoning is that 10.5+ can receive DNS from DHCP)
  3. Turns off the wireless card.

The script itself has been built from a few scripts contained within Caspers Resource Kit & then modified for 10.7+ by myself.
