dhcpcd script on SuSE 8.1

Hi, I'm tearing my hair out trying to get dhcpcd to run the dhcpcd.exe script on SuSE 8.1. I had this working on SuSE 8.0 without any problems. On 8.1 I have tried about everything to get it to run but to no avail. The script is to refresh my IP address at DynDNS.org. Has anyone managed to get a script running on this version of SuSE? If what are the magic steps. -- Thanks, Graham Smith ---------------------------------------------------------
