Hello,
We would like to track the open sockets on the machine. we don't want to use a constantly running thread that polls the open sockets (such as by using sysctlbyname) since it sometimes will miss short-lived sockets.
After some research we decided to implement a content filter (NEFilterDataProvider) that pass-through every socket flow.
However, as we see and read in the forum, all previously opened sockets are disconnected once the filter is applied, which is an undesired thing for users using a VPN that will disconnect as well.
We would like to know if there is a better way to track all sockets, preferably in an event-driven way, or, to prevent the existing sockets from disconnecting if we use the filter or other network extension.
