Install DNS Safety on Debian 9

The following steps show how to install DnsSafety filter on 64-bit Debian 9. It is recommended to download installation scripts mentioned on each step from our GitHub repository (sub folder scripts.debian9). Just run them one by one as root.

Step 1. Update

It is recommended to update the system prior to installation. Run bash 01_update.sh in the console.

#!/bin/bash

# update should be done as root
if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 1>&2
   exit 1
fi

# update, upgrade and reboot
apt update && apt -y upgrade && reboot

Step 2. Install

Run bash 02_dnssafety.sh in the console to install the latest stable version of Dns Safety. Note the /opt/dnssafety/bin/dsdnsd daemon runs as standard daemon user in Linux.

#!/bin/bash

# all packages are installed as root
if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 1>&2
   exit 1
fi

# default arc
MAJOR="0.7.0"
MINOR="B672"
ARCH="amd64"

# download
wget http://packages.diladele.com/dnssafety/$MAJOR.$MINOR/$ARCH/release/debian9/dnssafety-$MAJOR.${MINOR}_$ARCH.deb

# install
dpkg --install dnssafety-$MAJOR.${MINOR}_$ARCH.deb

# relabel folder
chown -R daemon:daemon /opt/dnssafety

Step 3. Integrate

Finally, to integrate DNS Safety filter with the system run bash 03_integrate.sh. The script is simple, it just restarts the dsdnsd daemon.

#!/bin/bash

# all packages are installed as root
if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 1>&2
   exit 1
fi

# recreate default /etc/resolv.conf
echo "nameserver 127.0.0.1" > /etc/resolv.conf

# and restart dns safety dns server
systemctl restart dsdnsd

Reboot your server now to see that everything comes back to life correctly after it.
