I finished installing RH Ent Workstation 5 at work. Monday I got to work and needed to make a change in the DNS. I typed the system-config-network and the followingerror came up:

...maybe it will help

cheers

Hi pelissier, welcome to LQ forums.

That Knowledge base article kbp posted says you have syntax error(s) in your /etc/hosts file. Either fix it your self, or post it here so we can help you.

This is the hosts file, I really don't see where I go wrong. Please Help

You are posting from Windows, did you by any chance edit and/or prepare that file/text in windows? End of lines could be problem, there is a difference between Windows and Linux text editors.

I have been using OpenOffice (Wordprocessor) to edit the hosts, that is probably where the problem came from. Now I am wondering if I have to open the Linux editor to recreate the file. Thank you for your info. let me know what should I do next.

Use Applications -> Accessories -> Text editor to retype it from scratch. That should be the best if you have not created a backup of the file. As a rule, any wise man will create a backup of anything he tries to change. Then it is easy te return the things to the way they were.

Thank you, I will try it monday and I will let you know the result. Have a nice weekend.
