Have you tried kCFStreamPropertySocketRemoteHost? (Although I haven’t found this property to work either in the related case of a stream opened from an _incoming_ TCP connection.) > Isn't this supposed to work?

My guess is that the address is resolved but at a lower level in the stack, and the resolved address doesn’t get stored into the NetService object itself. Which would be a bug. Workarounds I can think of: (a) Use a lower-level (Unix) API to get the remote address from the underlying socket file descriptor. I don’t know these APIs well enough to tell you how to do it, other than to guess that getsockopt might be involved. (b) Instead of calling the convenience routine CFStreamCreatePairWithSocketToNetService, DIY by first resolving the NetService, getting the address, and then opening streams to it. (c) Do without the address. There shouldn’t be much need for it, except for debugging purposes. —Jens _______________________________________________ Do not post admin requests to the list.
