Some of the security technologies we use to build FDNS: chroot, seccomp, and Linux namespaces. An AppArmor profile is installed in /etc/apparmor.d/usr.bin.fdns. The profile will kick in automatically on Debian and Ubuntu next time you start the computer. For systemd users, we provide a service file in /etc/fdns/fdns.service.

Starting the Proxy at Boot Time

One solution that will work on any Linux computer is to start it from /etc/rc.local.

$ cat /etc/rc.local
#!/bin/sh -e
/usr/bin/fdns --daemonize
exit 0

For systemd users, we place a fdns.service file in /etc/fdns directory. Usage:

cp /etc/fdns/fdns.service /etc/systemd/system/fdns.service

Load the file. Alternatively reboot your system

systemctl daemon-reload
systemctl start fdns.service

Start fdns when starting the system

systemctl enable fdns.service
