Thanks.</div> <div><br> </div> <div>At some point in my hopeless odyssey down a wrong track I tried giving the whole struct to inet_ntop() and forgot to change it back when I got everything else to work.</div> <div><br> </div> <div>Thanks for your help and sorry for the inconvenience.</div> <div><br> </div> <div>Cheers,</div> <div>Klaus<br> </div> <br> </div> </body> </html>
