Thanks for your responses. Yes, I saw that one too. However, none of the
"this is how you calculate the checksum for ...." tell me anything about the
*why* of using the UDP-length double :-( :-)

By the way : the sending & recieving of the UDP-packets to/from a
Windows-machine goes o.k., so I guess the checksum-calculation is o.k too.
