<heading>I'm in <tt>foo.bar.edu</tt>, and I can no longer reach hosts in <tt>bar.edu</tt> by their short names</heading>
|
||||
<p>
|
||||
The current version of <em>BIND</em> that ships with FreeBSD
|
||||
does no longer provide default abbreviations for non-fully
|
||||
qualified domain names other than the domain you are in.
|
||||
So an unqualified host <tt>mumble</tt> must either be found
|
||||
as <tt>mumble.foo.bar.edu</tt>, or it will be searched for
|
||||
in the root domain.
|
||||
<p>
|
||||
This is different from the previous behaviour, where the
|
||||
search did continue across <tt>mumble.bar.edu</tt>, and
|
||||
<tt>mumble.edu</tt>. Have a look at RFC 1535 for why this
|
||||
has been considered bad practice and even a security hole.
|
||||
<p>
|
||||
As a good workaround, you can place the line
|
||||
<p><tt>
|
||||
search foo.bar.edu bar.edu
|
||||
</tt><p>
|
||||
instead of the previous
|
||||
|
||||
<p><tt>
|
||||
domain foo.bar.edu
|
||||
</tt><p>
|
||||
into your <tt>/etc/resolv.conf</tt>. However, make sure
|
||||
that the search order does not go beyond the ``boundary
|
||||
between local and public administration'', as RFC 1535
|
||||
calls ist.
