Hi Sylvain, that is not a solution since I have to parse a string containing the IP.
Meanwhile it is working. The trick: I have to do a htonl/s() for all addresses that are used to configure the network interface (IP, netmask, gateway) but not for the IP and port number of the SNTP server to be contacted. Somewhat strange but works this way.
