Re: Hidden sniffer on unplumb'ed interface on Solaris

(http://www.enteract.com/~robt/Docs/Howto/Sun/sniffer-trick.txt) by Rob Thomas, it was brought to my attention that a sniffer can be silently sitting on an unplumb'ed interface on Solaris. Not only is this dangerous
This is actually very similar to how the stealth mode of the SunScreen firewall works it doesn't plumb up the interface so you can't directly attack the firewall by attempting connections to an IP address (it acts more like a bridge when working in this mode).
for large networks, it is often hard to find. Has anyone ever contacted Sun about this potential problem...I'm fixing to try this on Solaris 8 to determine if the problem still exists.
It isn't a problem is is a deliberate feature and is due to the way that the STREAMS framework and snoop work, this is NOT a bug. -- Darren J Moffat
