Hello Marcel

Thanks a lot. I hoped someone more c experienced will take a quick look at 
my code. It's the result of a example I found (the mistake comes from 
there) and a socket programming howto I read.

I now changed it to
addr.rc_channel = 4;

Actually I do not need to #define it for the whole file.

regards
Marco
