Hi: I am writing an application that joins a multicast stream on a specific UDP port. But when I run more than one instance of the same application, the second instance complains that the port is already in use. For example if I join stream 229.10.10.133:2000 on one instance and 229.10.10..134:2000 on another instance, the second one fails to join - I can however join it if I kill the first instance. I have compiled that application with SOCKET_REUSE option, but I wonder if I need to enable/recompile-with any special multicast kernel option for this to work. I do not have this problem when I run this code on Linux (Ubuntu 9.10) but I really want to get this working on FreeBSD. Thanks in advance. -DxN
