Hi, I am looking to track the number of syn packets coming into a system, as the box in question has pf running and using the synproxy attribute on tcp services, I hope to be able to use the synproxy field in pfctl -si. However I cant find a definitive definition of the variable, Ive looking in the source but haven't have much look in finding where it is derived. Can anyone shed any light on if my assumption is valid as without a proper definition of this variable I can't really trust its output is what i think it is. Alternatively if anyone could suggest an another way of tracking inbound syn packets I would be grateful, it must use base os tools though, ie no ports or other apps required. Thanks K
