Unbound is a validating, recursive, and caching DNS resolver.
The C implementation of Unbound is developed and maintained by
NLnet Labs. It is based on ideas and algorithms taken from a java
prototype developed by Verisign labs, Nominet, Kirei and ep.net.
Unbound is designed as a set of modular components, so that also DNSSEC
(secure DNS) validation and stub-resolvers (that do not run as a server,
but are linked into an application) are easily possible.
A user and group are recommended to run Unbound. The following should
not conflict with anything else on SlackBuilds:
groupadd -g 304 unbound
useradd -r -u 304 -g unbound -d /etc/unbound/ -s /sbin/nologin -c \
'Unbound DNS resolver' unbound
Optional DNSCrypt support is provided. To enable:
DNSCRYPT=yes ./unbound.SlackBuild
This will require libsodium which is available at SlackBuilds
