Linux c++ Ipv6 UDP Client/Server Problem

[xDer]

Hey! I am using UDP sockets in IPV6 and i can't get the server to receive the packet sent by the client to the All Hosts ipv6 address ff02::1. The client is sending the packets as i see them in the wireshark. Can you help please?

 }

   cout << " new packet arrived with " << len << "bytes!" << endl;
 }

}
