Unhappy Could not look up internet address for .. This will prevent GNOME from operating corr


I just installed Redhat 9 on my computer (AMD Athlon 800MHz, 384MB RAM if that helps).

After I sign in, the following message pops up:

Could not look up internet address for .. This will prevent GNOME from operating correctly. It may be possible to correct the problem by adding . to the file /etc/hosts

What does this mean and what should I do?

If it helps at all, the default gateway for my network is (but I've got no idea what the message means, so I don't really know if this will help).

I've had the same problem and my gateway is the same too, I tried adding that to the /hosts file but nothing came of it.. so it's just frustrating to have to click the continue button everytime..

again if anyone knows something about this.. please!!!!

You essentially will need to add: localhost localhost.localdomain

to your /etc/hosts file.

and if you do not have a /etc/hosts file, CREATE ONE, and add the above lines please.

maybe this will help you, too:

on RedHat/Fedora:


edit your computer's eth0 connection, and give your computer a hostname

i have it figured out:
add a line which looks like this in your etc/hosts file. localhost.localdomain localhost CPE00508d512248-CM014310003069
the long string of random numbers and letters is computer specific you will need to find out yours. also, to edit this file you will need to be could either goto the console andenter the following:

cd /
vi etc/hosts (i suggest u enter vi-h to see avilable commands for use with vi)

(the above is a text editor not easy to use unless you know how)
(move to the line you want to edit)
press insert(allows the entering of text(press esc to exit insert mode))
after entering your alterations you must save to do this:
damn i cant remember to save i am just a ill go and
anyone how to save with vi?

edit: it seems that the alterations are saved on exit so you could alterate and then exit and you are all good!

i know you must:
the dots brings u a command enter mode you use single letters to specify actions
x will exit

anyways i hope this does not u but i am 2 weeks new to linux.
good luck

The string of numbers that you refer to is irrelevant. I'm not sure why you have it, it might be your ethernet address number, which is like a serial number for your ethernet card. Anyway, the problem comes up if you name your computer during the setup process, but the name is not registered in a DNS. So all that you need in your /etc/hosts file is: localhost.localdomain localhost

If your network uses DHCP, computer can look up a different hostname for your computer from a DNS, it will and will automatically set it for you. If you are just a home user with a modem, don't worry about it.

Due you have an additional hostname in front of the ip address, like this?

some.hostname localhost.localdomain localhost

The problem on my machine was that I had that hostname there. I had to delete it.

Do you have any other lines in /etc/hosts?

I have RH9 ( Shrike)
Kernel: 2.4.20-8 on an i686

This was my solution so I don't have to close that message box all the time.

I edited the /etc/hosts file as the "root".
