[Mono-list] IPEndPoint/Socket.Bind behaviour
Tue, 5 Apr 2005 16:18:50 +0100
I'm developing a multi-homed server app. that has to listen for
broadcast UDP. I've tried the following:
EndPoint local = new IPEndPoint(ip, port);
Where "ip" is an IPAddress with a parsed address or hostname and
"listen" is a Socket instantiated with SocketType.Dgram,
ProtocolType.Udp. However, this endpoint never receives any data.
Changing the code to:
new IPEndPoint(IPAddress.Any, port);
works, but this means that you can't have multiple listeners without a
SocketOptionName.ReUseAddress, 1) call.
I've tried the same code in .NET and it works in the original
configuration, i.e. as:
EndPoint local = new IPEndPoint(ip, port)
For the time being the SetSocketOption workaround is sufficient as all
interfaces are in the same address range, however I can't see how this
would work with different address ranges.
Can anyone shed on light on this?
