Well i have installed redhat9 and get an error message after i log in. It says that an internet address for x1-6-00.... was not found and may be added in /etc/hosts for gnome to run properly. I did add the address in /etc/hosts and am still encountering the problem and the same error. It also takes a long time for all of the icons to load up and for applications to open. Once i run iptables -F. Everything is fine, but i want to be able to not deal with a 2 minute load time for everything to open until i run iptables -F. Any suggestions?

check your hostname in /etc/sysconfig/network
and add this hotname in /etc/hosts like this:
127.0.0.1 HostName.Domain.Com HostName localhost.localdomain localhost

Hey amxut, i have done what you said, and i am still having the same error, along with the slllooww load time of the icons after login. Any other suggestions. Thanks.

have u changed your hostname? i had same problem. when i changed my hostname, i got same error. and gnome was working so slowly. i added my hostname in /etc/hosts as i told u, and it worked. what are the outputs of followings:
hostname
cat /etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
My host name is : x1-6-00-07-e9-b6-06-37


This is my lines when i do cat /etc/hosts. If i need to change the host name can you please tell me, or if there is a different way around solving this issue. Thanks
