<div class="moz-cite-prefix">Hi Jakob,<br>
<br>
I am using the UDPServer for which the the host is localhost by
default and in the code (Driver.cpp, line 191) it says (UDP
udpserver://localport).<br>
<br>
After discusing it with Matthias, it seems during the write
(IOStream.cpp, line 121) it uses sendto and the destination addr
is not set or in my case not even known. Could this be the
problem?. Maybe after creating the server, I need to read
something from the udp-client before using sendto.<br>
<br>
regards<br>
Ajish<br>
