- Fix http2 drop handling to clear the postpone_drop state so that
other streams on the http2 session are not affected by a drop,
  and can clean up properly if also dropped. Fix http2 send reply
  so that when there is a send failure is does not recurse into
  the mesh functions and also does not drop the connection due to
  the condition of one stream.

Unbound

Github Build Status Packaging status Fuzzing Status Documentation Status Mastodon Follow

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. Dont 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. If building from the repository source you also need flex and bison 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 (e.g., 10000) outgoing ports. Use the --with-libevent configure option to compile Unbound with libevent support.

If not, the default builtin alternative opens max 256 ports at the same time and is equally capable and a little faster.

Unbound configuration

All of Unbound's configuration options are described in the unbound.conf(5) man page, which will be installed and is also available on the Unbound documentation page for the latest version.

An example configuration file, with minimal documentation, is located in doc/example.conf.
