Unbound-1.4.20
Introduction à Unbound
Unbound is a validating,
recursive, et caching DNS resolver. It is designed as a set of
modular components that incorporate modern features, such as
enhanced security (DNSSEC) validation, Internet Protocol Version 6
(IPv6), et a client resolver library API as an integral part of the
architecture.
Ce paquet est connu pour se construire correctement sur une
plateforme LFS-7.4.

Installation de Unbound
There should be a dedicated user et group to take control of the
unbound daemon after
it is started. Issue the following commands as the root user:
groupadd -g 88 unbound &&
useradd -c "Unbound DNS resolver" -d /var/lib/unbound -u 88 \
-g unbound -s /bin/false unbound
Installez Unbound en lançant les
commandes suivantes :
./configure --prefix=/usr \
--sysconfdir=/etc \
--disable-static \
--with-pidfile=/run/unbound.pid &&
make
If you have Doxygen-1.8.5 package installed et want to
build html documentation, run the following command:
make doc
To test the results, issue make
check.
Maintenant, en tant qu'utilisateur root :
make install &&
mv -v /usr/sbin/unbound-host /usr/bin
If you built html documentation, install it by running the
following commands as the root
user:
install -v -m755 -d /usr/share/doc/unbound-1.4.20 &&
install -v -m644 doc/html/* /usr/share/doc/unbound-1.4.20
Explications des commandes
--disable-static: Ce
paramètre empêche l'installation des versions statiques des
bibliothèques.
--with-libevent : This option enables
libevent support allowing use of large outgoing port ranges.
--with-pyunbound : This option enables
building of the Python bindings.
Configuring Unbound
Config Files
/etc/unbound/unbound.conf
Configuration Information
In the default configuration, unbound will bind to localhost
(127.0.0.1 IP address) et allow recursive queries only from
localhost clients. If you want to use unbound for local DNS
resolution, run the following command as the root user:
echo "nameserver 127.0.0.1" > /etc/resolv.conf
If you are using a DHCP client for connecting to a network,
/etc/resolv.conf gets overwritten
with values provided by DHCP server. You can override this, for
example in DHCP-4.2.5-P1, by running the following
command:
sed -i '/request /i\supersede domain-name-servers 127.0.0.1;' \
/etc/dhcp/dhclient.conf
For advanced configuration see /etc/unbound/unbound.conf file et the
documentation.
Boot Script
If you want the Unbound server
to start automatically when the system is booted, install the
/etc/rc.d/init.d/unbound init
script included in the blfs-bootscripts-20130908
package.
