His machine does have it in /etc/defaults/rc.conf (I assume this is where
it's supposed to be because my /etc/rc.conf file doesn't have it either but
I do have it in /etc/defaults/rc.conf), but not in /etc/rc.conf.  Basically,
his rc.conf files look nearly identical to mine (mine works).  I didn't look
closely at this /etc/hosts file as the other respondent mentioned but I
will.
