Basic installation instructions are located in ISC's knowledgebase at: https://kb.isc.org/docs/kea-build-on-debian.

What follows are notes for installing Kea with advanced features, including RADIUS and sysrepo. These features depend on other open source projects and the installation is more complicated as a result.

Installing with FreeRADIUS

@(Warning)()(You need to have the radius hook package for this to work)

Install FreeRADIUS client first.

wget -nd https://github.com/FreeRADIUS/freeradius-client/archive/release_1_1_7.tar.gz
tar zxvf release_1_1_7.tar.gz
cd freeradius-client-release_1_1_7
./configure --prefix=/usr/local
make
sudo make install

Extract Kea subscription radius hooks package to premium/ dir:

tar zxvf kea-radius-1.5.0.tar.gz
autoreconf -if
./configure --with-freeradius=/usr/local

Make sure the following entries are printed after configure is done:

then compile as usual.
