Thank you very much for the reply...
This was what was in my /etc/hosts before your response...
::1 IBM-R40e [EMAIL PROTECTED]
127.0.0.1 IBM-R40e [EMAIL PROTECTED]
192.168.1.35 IBM-R40e [EMAIL PROTECTED]
This is my new /etc/hosts now:
::1 localhost
127.0.0.1 localhost
10.0.0.1 [EMAIL PROTECTED]
I had to supply 10.0.0.1 [EMAIL PROTECTED] 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...
