Why can I ping the hostname, but not the fully-qualified domain name of

I remember something related to the "/etc/nsswitch.conf" file, the
order of the queried facilities and also the avahi issue with ".local"
domains...
sm01@stt008:~$ cat /etc/nsswitch.conf|grep hosts
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
And let's see if I can ping a local machine using its FQDN:
sm01@stt008:~$ ping -c 3 stt008.linux.site
PING stt008.linux.site (192.168.0.8) 56(84) bytes of data.

Yes, I can ping *but* I have the above machine listed in my "/etc/hosts"
file.
sm01@stt008:~$ cat /etc/hosts
127.0.0.1 localhost
192.168.0.8 stt008.linux.site stt008
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
Just for testing purposes yo can try with:
hosts: files mdns4_minimal dns mdns4
Or:
hosts: files dns mdns4_minimal [NOTFOUND=return] mdns4
(note: I'm sure this was documented in some place but can't find the source
now)
