I am using Distributed Object for client server communication. I am storing clients object on the server for further communication between clients. when client terminate it will notify server about termination using -(NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication *)sender method and server remove object of that client and notify other clients but if someone kill the client then how to notify server about termination?
See the section Handling Connection Errors in the Distributed Objects Programming Topics. The NSConnection objects will handle that case.
