Hi, as a comsequence of a virus diffused in my customer-base, I often receive big bursts of traffic on my DNS servers. Unluckly, a lot of clients start to bomb my DNSs at a certain hour, so I have a distributed tentative of denial of service. I can't blacklist them on my DNSs, because the infected clients are too much.
For this reason, I would like that a DNS could response maximum to 10 queries per second given by every single Ip address. Anybody knows a solution, just using iptables/netfilter/kernel tuning/BIND tuning, without using any hardware traffic shaper?
