Package: sudo
Version: 1.8.9p5-1
Followup-For: Bug #731583

This bug is still present in 1.8.9p5-1.

I thought you'd want to know that manipulating the 'fqdn' setting
(which is on by default anyway) does not have any effect.

I found the following relating to the 'fqdn' option in sudoers(5):

   This option is only effective when the “canonical” host name, as
   returned by the getaddrinfo() or gethostbyname() function, is
   a fully-qualified domain name.  This is usually the case when the
   system is configured to use DNS for host name resolution.

   If the system is configured to use the /etc/hosts file in
   preference to DNS, the “canonical” host name may not be
   fully-qualified.

What does this mean? And if so, why must it not be fully-qualified?

The manpage continues:

   In the /etc/hosts file, the first host name of the entry is
   considered to be the “canonical” name; subsequent names are
   aliases that are not used by sudoers.  For example, the following
   hosts file line for the machine “xyzzy” has the fully-qualified
   domain name as the “canonical” host name, and the short version
   as an alias.

      192.168.1.1    xyzzy.sudo.ws xyzzy

Right, this is what I have…

   If the machine's hosts file entry is not formatted properly, the
   fqdn option will not be effective if it is queried before DNS.

So is this properly formatted?
