Install Xmanager problem

I have installed a new system of Suse Linux 10 Enterprise version. Also I have download the Xmanager and planing use Xmanager to connect Suse Linux.
I have following this link to make setting changed: NetSarang - Xmanager FAQ. But there is some problem when I’m tried to following the setting.

  1. In step2, it said I need update kdmrc in /etc/opt/kde3/share/config/kdm/. However there is no this folder and file. Could you tell me where I can update this file?

  2. How can I open the port 177 and 6000~6010 port? I cannot find where I can changed.

Thank you.
