Ask for help!(host authentication failed.did you forget the domain?)

[kong guilan]

Hi,everyone.
  I have installed cfengine on two 
hosts(192.168.40.31/kgl,192.168.40.131/chf),kgl is working as a server 
host, and chf is working as a client host.I want to connect to server kgl 
from host chf.And i have customed cfservd.conf,cfagent.conf and update.conf 
on both hosts (including cfrun.hosts on server kgl).But when i run cfagent 
from chf,i encountered an error:
  Host authentication failed.Did you forget the domain name?
  Now i have recorded the complete information of 'cfservd -d2'command on 
server kgl.I put part of the information in the following:
