I'm not convinced at all that there's any sort of security issue here. It is marginally less secure based on thus: Any OS can be violated to provide root access. In normal circumstances the ethernet interface does not expose other packets. On a system running with the interface in promiscuous mode it does expose other packets. Thus if the system's security is breached (i.e. the box is rooted) it exposes more than the normal level of information about your network without the perpetrator needing to act (i.e. run a scanner of their own) to get it. Like I said it's minimal. If your box gets rooted you are screwed anyway ;) Yup, we are in agreement..."practically nonexistent". ;) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
