Check the /etc/resolv.conf file for a "domain corbin.machturtle.com"
entry. If it is missing, that is the problem. The resolver doesn't know
what domain to append to the host name. host will ask the nameserver for
data. If the nameserver machine has the host in DNS or the /etc/hosts
file, it will return a correct reply. But the local machine doesn't use
the host command to resolve names. It only uses the settings defined in
/etc/nsswitch.conf (often host,dns). The usual dns request will not pull
data from a remote machines /etc/hosts file unless that machine is set
to publish the data through bind.
