As I said, save it with the name hosts.orig
. Now, you have a copy of that safe and sound.
Open /etc/hosts again and edit it to read like this:
127.0.0.1 localhost.localdomain <your-computer's-name>
Now save it
Try stuff. If it breaks something,
mv /etc/hosts.orig /etc/hosts
You are back at the beginning.
If it fixes it,
cp /etc/hosts /etc/hosts.works
Or something similar.
You have to get your hands dirty with Linux.
Install Midnight Commander if you can. It's a real neat application and makes the command line a breeze if you break X.
