This was what was in my /etc/hosts before your response... ::1 IBM-R40e IBM-R40e@point.ne.jp 127.0.0.1 IBM-R40e IBM-R40e@point.ne.jp 192.168.1.35 IBM-R40e IBM-R40e@point.ne.jp This is my new /etc/hosts now: ::1 localhost 127.0.0.1 localhost 10.0.0.1 IBM-R40e@point.ne.jp I had to supply 10.0.0.1 IBM-R40e@point.ne.jp because Gnome 2 complains that it can not find it...So, I just invented it...I hope that it is right... One thing I do not I understand is that when I do: %host localhost. It will be give a "Host not found" response...But, my system is working fine...What do you think is wrong with it... Once again, thank you for the response... Rommel Ikedahome | help
