Bandwidth and CPU drain #48

Open BradPerbs opened 4 years ago

BradPerbs commented 4 years ago

Any tip to reduce the CPU and bandwidth usage?

I'm currently using 2x KVM VPS in round robin with 20 and 8 cores, but with a simple attack, I reach 700 Mbit on both and 100% CPU usage.

Maybe a mitigation system that ban the hosts in netflow could work?

If you have any suggestion please let me know

BradPerbs commented 4 years ago

any ideas on how to filter that 80%?

Use services that provide ddos mitigation

Use services that provide ddos mitigation

For "services" you mean providers? because in that case will not work, since that mitigate only Layer 3/4 traffic, not layer 7 HTTP legitimate traffic

This is where things get complex and I could solve it by allowing the script to take control of the servers built in firewall. For windows server users this would be netsh advfirewall and Linux would be iptables -A INPUT -s 192.168.0.1 -j DROP

I have the ability with Nginx Lua to access os.execute in order to run such things through a command line or console but i am looking at io.popen a bit more since os.execute blocks threads and workers while they run and io.popen is non blocking so will allow others users requests to finish and connect still.

Seems like a useless tool antiddos then..

You have to break 80% of attack before arriving to NGINX.. if the attack arrives to nginx the host will go offline for high CPU Usage.
