Sticky-drop

What's this? Sticky-drop? Can someone provide a link to more information? Google searches have not been fruitful. I'm using snort 2.4.3 and a grep of the source tree for "sticky" came back with nothing. Is there a patch? Also, are there any known bugs with connection resets? I think the reset packets may not be getting sent to both ends of the connection or else might not have the proper source port set. Finally, there's a bug filed on Sourceforge that says that "After a lot of tries, a packet can pass through snort-inline" [1]. Is this a confirmed issue. I've seen some behavior that suggests it could be true, but I haven't tracked it down yet. Thanks, ..Patrick 1. http://sourceforge.net/tracker/index.php?func=detail&aid=876404&group_id=78497&atid=553467 On Tue, 2005-12-06 at 11:19 -0600, Will Metcalf wrote:
sticky-drop in snort-inline can do this. You could probably accomplish the same thing with Snortsam In InlineMode(); but I haven't tried it.
