Thanks for your very fast answer. You can find the dump (dumped at the          
server) of the client-server communication at:                                  
http://gustav.informatik.tu-chemnitz.de/~htor/sec/tcpdump-afs.dump              

(read with tcpdump -r, this file will be deleted tomorrow)                      

Does this help? Or are there any other debug possibilities?                     

Thanks & Kind Regards,

PS: Sorry for the personal mail Harald!
