I realize this isn't directly xcode related but figure there are a lot of really smart people on this list too, please suggest a better list, as i'm not sure where to go:
so my app can connect to a "Cloud" data bank and download all the cloud data, that's 10,000 or so files (for offline access).
the app makes a few net-calls for each file (query for correct URL, query header, finally get the file)
in testing, i kept getting errors about "too many open ports", so i went to Activity Monitor, clicked my app, clicked "inspect", then clicked "open files and ports"
lo-and-behold:
a zillion ports open to (and this is the mystery):
> 192.x.x.x:49446->ec2-54-243-119-94.compute-1.amazonaws.com:https
(192.x.x.x is my localhost)
i'm like , "what?"
my app doesn't contact amazon web services!??!
so i did some sleuthing
i turned OFF all cloud stuff, AND turned off automatic version check. so there is NO net activity on the app now.
when i start it, there are NO ports open to aws
okay, good
then i do "help->check for update", the app checks a file at dropbox (to see if there's an update), which is expected
but THEN appears to open a port to AWS, and leaves it open!!
for every "check for update" i do, another port is opened and left open.
why, why, why?!?!
Little Snitch found nothing related to AWS
turning on firewall blocking all incoming did nothing
