Fix problems of miscellaneous network services

A bug in anaconda and another in system-config-network can lead to a broken /etc/hosts file. This results in various networking services not starting or otherwise missbehaving.

Applicable to Fedora Versions

Fedora Core 6

Doing the Work

Open a terminal and check if you are affected by the problem
```
ping -c 1 localhost
```
If the output is
```
ping: unknown host localhost
```
you're suffering from the problem. If not you may still want to follow this howto (skipping step 5) so this bug doesn't bite you later.
Become root
```
su -
```
Change to the /etc directory
```
cd /etc
```
Create a backup file of the hosts file
```
cp hosts hosts.orig
```
Open the hosts file in your favourite editor and add this enty
```
127.0.0.1    localhost.localdomain localhost
```

Modify the entry

::1          localhost.localdomain localhost

so it reads

::1          localhost6.localdomain localhost6

Save the modifications and exit your editor
Give up root priviledges
```
exit
```
