- Merge #944: Disable EDNS DO.
Disable the EDNS DO flag in upstream requests. This can be helpful
for devices that cannot handle DNSSEC information. But it should not
be enabled otherwise, because that would stop DNSSEC validation. The
DNSSEC validation would not work for Unbound itself, and also not
for downstream users. Default is no. The option
is disable-edns-do: no
Unbound is a validating, recursive, caching DNS resolver. It is designed to be
fast and lean and incorporates modern features based on open standards. If you
have any feedback, we would love to hear from you. Don’t hesitate to
create an issue on Github
or post a message on the Unbound mailing list.
You can learn more about Unbound by reading our
documentation.
Compiling
Make sure you have the C toolchain, OpenSSL and its include files, and libexpat
installed. Unbound can be compiled and installed using:
./configure && make && make install
You can use libevent if you want. libevent is useful when using many (10000)
outgoing ports. By default max 256 ports are opened at the same time and the
builtin alternative is equally capable and a little faster.
Use the --with-libevent=dir configure option to compile Unbound with libevent
support.
Unbound configuration
All of Unbound's configuration options are described in the man pages, which
will be installed and are available on the Unbound
documentation page.
