DNS Probe can be used on Linux with kernel version at least 3.11. It also requires the system to support C++14 standard. Installation packages are available from OBS (openSUSE Build Service). The following distributions are currently supported: Debian 12, 11, 10 and 9; Ubuntu 22.04, 20.04, 18.04; Fedora 38, 37, 36, Rawhide; EPEL 8 and Arch.

The OBS repository also contains packages with several dependencies that are not provided by the distribution’s standard repositories. These dependencies will be automatically installed as pre-requisites when installing DNS Probe.

On Linux distributions that are not (yet) supported, DNS Probe has to be compiled and built from source as described below.

Installation from packages


sudo apt-get update
sudo apt-get install -y lsb-release curl gpg

DISTRO=$(lsb_release -i -s)
RELEASE=$(lsb_release -r -s)
if [[ $DISTRO == "Ubuntu" ]]; then DISTRO="xUbuntu"; fi
if [[ $DISTRO == "Debian" && "$RELEASE" =~ ^9\..*$ ]]; then RELEASE="9.0"; fi

echo "deb${DISTRO}_${RELEASE}/ /" | sudo tee /etc/apt/sources.list.d/dns-probe.list
curl -fsSL${DISTRO}_${RELEASE}/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/dns-probe.gpg > /dev/null
sudo apt-get update
sudo apt-get install dns-probe-af dns-probe-dpdk dns-probe-collector


sudo dnf config-manager --add-repo$(cut -d: -f5 /etc/system-release-cpe | cut -d. -f1)/home:CZ-NIC:dns-probe.repo
sudo dnf install dns-probe-af dns-probe-dpdk dns-probe-collector

Fedora Rawhide

sudo dnf config-manager --add-repo
sudo dnf install dns-probe-af dns-probe-dpdk dns-probe-collector


cd /etc/yum.repos.d/
sudo wget
sudo yum install dns-probe-af dns-probe-dpdk dns-probe-collector


echo "[home_CZ-NIC_dns-probe_Arch]" | sudo tee -a /etc/pacman.conf
echo "Server =$(uname -m)" | sudo tee -a /etc/pacman.conf

key=$(curl -fsSL$(uname -m)/home_CZ-NIC_dns-probe_Arch.key)
fingerprint=$(gpg --quiet --with-colons --import-options show-only --import --fingerprint <<< "${key}" | awk -F: '$1 == "fpr" { print $10 }')

sudo pacman-key --init
sudo pacman-key --add - <<< "${key}"
sudo pacman-key --lsign-key "${fingerprint}"

sudo pacman -Sy home_CZ-NIC_dns-probe_Arch/c-dns

Three alternative packages are available:

  • dns-probe-af is compiled with support for AF_PACKET sockets
  • dns-probe-dpdk uses the DPDK framework.
  • dns-probe-collector is a collector for data exported from DNS Probe via the remote export feature.

Installation from source

This project has several dependencies that have to be installed first. The following packages should be available from standard distribution repositories:

  • CMake, version at least 3.5
  • Boost (C++ libraries)
  • libpcap
  • yaml-cpp
  • OpenSSL (libssl-dev)
  • fstrm
  • Protocol Buffers (libprotobuf-dev, protobuf-compiler)
  • libmaxminddb
  • libknot, version at least 3.0.6
  • DPDK (only for DPDK version)

Optionally, to build this user documentation (make doc) or manual pages (make man) one additional dependency is required:

  • Sphinx

The following instructions describe how to compile DNS Probe and the remaining dependencies. Also this approach installs all dependencies into local directory dp-dep.

Build directory

Start with creating a directory where DNS Probe and dependencies will be built and installed. Installation in a system directory, such as /usr/local, is also possible.

mkdir dp-dep
mkdir dp-dep/build
mkdir dp-dep/dl
cd dp-dep

Apache Arrow

Apache Arrow packages can be installed on most distributions from Apache’s own repositories. Debian/Ubuntu libarrow-dev and libparquet-dev packages or their equivalents in other distributions need to be installed for successful compilation of DNS probe.

C-DNS Library

C-DNS Library is used for working with the C-DNS format.

curl -L > dl/cdns.tgz
mkdir build/cdns
tar -xf dl/cdns.tgz -C build/cdns --strip-components=1
mkdir -p build/cdns/build
cd build/cdns/build
# Remove -DCMAKE_INSTALL_PREFIX="$DEP_DIR" if you want to install CDNS into /usr/local
make -j
make install
cd "$DEP_DIR"


Library for anonymization of IP addresses.

curl -L > dl/cryptopant.tgz
mkdir build/cryptopant
tar -xf dl/cryptopant.tgz -C build/cryptopant --strip-components=1
cd build/cryptopant
./configure --prefix="$DEP_DIR"
make -j
make install
cd "$DEP_DIR"


In case your distribution doesn’t yet have libknot >= 3.0.6, the latest package can be installed from Knot DNS’s own repositories. Debian/Ubuntu libknot-dev package or its equivalent in other distributions needs to be installed for successful compilation of DNS probe.

DNS Probe

# Replace <GIT_REPO> with path to this repository
# For disabling DPDK BACKEND remove `-DDPDK_BACKEND=On`
# For building without IP anonymization support add `-DPROBE_CRYPTOPANT=Off`
# For building without support for one of the export formats add `-DPROBE_PARQUET=Off` or `-DPROBE_CDNS=Off`
# For building without support for dnstap input add `-DPROBE_DNSTAP=Off`
# For building without support for Knot interface input add `-DPROBE_KNOT=Off`
make -j
make install
