Hi.. I'm a newbie to sockets and networking in general, so please forgive me if I ask something that's blatantly obvious to everyone else.. :-)

I'm trying to learn about CFSockets and CFNetServices and have been looking at the Echo and Echo Client examples in the Jaguar Developer Tools.

So I've got a couple of instances of the Echo server running, and when I run the Echo Client, it finds them both just fine.


[podunk:networking/echo client/build] justin% ./Echo\ Client
Hit Ctrl-C to stop the search...
podunk 1.local.
podunk.local.


Then, if I give one of those name+domains as the command line arg, it goes into ConnectAndUseService(), creates the service, schedules it with the run loop, resolves the service and runs the loop. But it never gets into the ServiceCallback() and never connects with the echo server I specified.

I watched the WWDC DVD with the session on this example, and added a line to print out the port # of the server. I can telnet to that port and the echo server works fine that way. But the WWDC session never touched on the Echo Client app.

What am I missing here? It must be something fairly obvious....

Justin
