setting up ddclient with dyndns.org

Hi,

Just trying to set up ddclient on Centos. The readme file states:
cp ddclient /usr/sbin/
  mkdir /etc/ddclient
  cp sample-etc_ddclient.conf /etc/ddclient/ddclient.conf
  vi /etc/ddclient/ddclient.conf
  -- and change hostnames, logins, and passwords appropriately

  ## For those using Redhat style rc files and using daemon-mode:
  cp sample-etc_rc.d_init.d_ddclient /etc/rc.d/init.d/ddclient
  ## enable automatic startup when booting
  /sbin/chkconfig --add ddclient
  ## start the first time by hand
  /etc/rc.d/init.d/ddclient start

I'm not certain if I was to do the first few steps, that is:
cp ddclient /usr/sbin/
  mkdir /etc/ddclient
  cp sample-etc_ddclient.conf /etc/ddclient/ddclient.conf

When I try to execute the last step, that is:
/etc/rc.d/init.d/ddclient start

I receive this:
Starting ddclient: WARNING:  file /etc/ddclient/ddclient.conf: file /etc/ddclient/ddclient.conf must be accessible only by its owner (fixed).
                                                           [  OK  ]

I'm not logged in as root but I'm as su.

I have this in my /etc/ddclient/ddclient.conf

##
## dyndns.org dynamic addresses
##
## (supports variables: wildcard,mx,backupmx)
##
# server=members.dyndns.org,            \
# protocol=dyndns2                      \
# your-dynamic-host.dyndns.org

I'm assume that:
your-dynamic-host.dyndns.org
should be my hostname which is:
seokingdomheaven.dyndns.org

I'm not certain what this line should be changed to:
server=members.dyndns.org,

I'm still new to this and I read most of the pertinent information on the dyndns but I'm not certain how to set up my dynamic web server on my ISP.

Thank you,
