[Pdns-users] [HELP REQUEST - protect PowerDNS] I have had a brutal mass-attack

[kim Doff]

Hello,

I have PowerDNS Authoritative Server is 2.9.22 on Centos 5.5 32 bits.

I do not allow external recursion but I have had a brutal mass-attack
from China and Romania. It is a "recursion was desired" attack.

Does anyone know how to configure fail2ban to protect port 53?
Is there a Tutorial for that? I am a newbie.

I tried with iptables but I need something that automaticaly
blocks ips.

Best Regards,

Kim
