Older Dec 30, 2010 issue 3 (Multiple processes on the same machine cannot subscribe to t...) commented on by joe.harris - See the response to issue 2 See the response to issue 2 Dec 30, 2010 issue 8 (Multiple subscribers?) commented on by joe.harris - If you add: SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true); To the PgmSocket it will let you have multiple subscribers. I just tested it by dropping that line in the constructor. Note: I copied this from kelly.elias's response to issue 2 If you add: SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true); To the PgmSocket it will let you have multiple subscribers. I just tested it by dropping that line in the constructor.

Nov 30, 2010 issue 8 (Multiple subscribers?) reported by kelly.elias - I noticed that Emcaster only lets you bind once to the port and therefore you can have only a single subscriber. Is there a way to have multiple? I noticed that Emcaster only lets you bind once to the port and therefore you can have only a single subscriber. Is there a way to have multiple?

On what operating system? 0.1.5 Please provide any additional information below. see the sour code below of MessageParser: public unsafe void ParseBytes(EndPoint endpoint, byte[] buffer, int offset, int received) { _endPoint = EndPoint; //it should be _endPoint = endpoint _buffer = buffer; _offset = offset; What version of the product are you using?

Does it has another better solution to solve it? Thank you in advance! Now,I only re-connect the EndPoint once this exception is happened. Does it has another better solution to solve it? Thank you in advance! Sep 29, 2009 issue 6 (SocketException: An existing connection was forcibly closed ...) reported by Ctamor - What steps will reproduce the problem? 1. Connect the multicast group by using service application. 2. Pull up the Network Cable to disconnect the LAN. 3. Then Plug in the Network Cable to connect the LAN. What is the expected output? What do you see instead? We can also send the PGM message to LAN succeed. However, There is some socket exceptions.Please see the detail information below.Thanks! What version of the product are you using? On what operating system? The version is the latest one, and the Operation system is Windows Server 2003. Please provide any additional information below.

I copied the code from the sample code and it doesnt work. No excpetions . nothing heppends. What could be the problem? TIA Hello, I created 2 Wpf programms: one publisher the other subscriber.

TIA Dec 04, 2008 issue 4 (Publisher binding to a specific interface) reported by battand - Hi Mike, I'm trying to bind a emcaster publisher to a specific interface on my multi-homed machine. In looking at your code, it appears as if all I need to do is set the PgmSource's BindInterface to the IP of the interface I wish to bind to, but no matter what I set it to, calling PgmSource's Start() throws a SocketException. Do you have any ideas on how I would go about this? BTW, Excellent job with emcaster!!!!

Thanks, Andrew Battaglia Oct 23, 2008 issue 3 (Multiple processes on the same machine cannot subscribe to t...) reported by russellwilby - What steps will reproduce the problem? 1. Run more than one process/program on the same machine that subscribes to the same multicast address. What is the expected output: 1. PgmReceiver throws the following socket exception "Only one usage of each socket address (protocol/network address/port) is normally permitted". What version of the product are you using? .Net Emcaster Beta 0.1.5 on 32bit windows (XPSP2/2003 server). Comments: To resolve this we need to set the socket option which allows address reuse. We could add functionality to expose the underlying socket/socket options. The socket option code looks like this: socket.SetSocketOption(SocketOptionLevel.Socket,SocketOptionName.ReuseAddress, 1); Thanks and regards, Russ. What steps will reproduce the problem? 1.
