Attention! This advice can be understood misleading and wrongly
following can cause severe network problems. As the comment in the
/etc/hosts file itself very clearly says:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost

So if you have an own IP, i.e. one from private IP area, then add a
further line to the hosts file, like:

192.168.11.12	long.host.name	short

If just 127.0.0.1 is used, then the existing line has to be changed to
something like:

127.0.0.1	localhost.localdomain	localhost	long.host.name	short

Keep in mind that some applications like Sendmail do take the first
"dotted" name as the hostname.
