Logging DaoC Packets?

Hi, I am currently trying to sniff packets, incoming from freeshards. Well that works, but they are corrupted... As an example I can get a player update with the X Y Z coordinate, but not the session ID or sometimes the numbers are corrupted too.

Best way to receive proper packets from daoc server? Or am i using just a bad lib for sniffing packets?

Thanks...

Edit: The Sniffer was wrong... Thanks anyways...
