It might be a good thing to add that you should use your
Fully Qualified Domain Name followed by your short name in /etc/hosts
because if /etc/host.conf and/or /etc/nsswitch.conf is set to
look at hosts first and dns later the entry in /etc/hosts
will be used by `hostname -f` to get the fully qualified domain name
which won't work if it isn't there.

So if the entry in /etc/hosts is

m.y.i.p		myhostname.domain.name	myhostname

hostname will return myhostname
hostname -f will return myhostname.domain.name

If the entry is just

m.y.i.p		myhostname

hostname and hostname -f will both return myhostname
