Hmm, this might be: "the administrator *should* know" as this information seems to be buried deep down inside the Winpcap documentation. I'm using WinPcap for a long time, read the documentation not only once, but wasn't aware of this fact :-(

I've started a new Wiki page at: http://wiki.ethereal.com/Security, describing in a user's point of view the reasons and steps to do. Other's might provide informations for other platforms than windows (as I only know that platform good enough).

The page information might be included in the user's guide one day.
