Having been the weekend the standard filtering passed us through, we'll ask the datacenter to filter against these attacks today, It's Spoofed DNS Amp UDP/SYN, I've had IPs from Germany, netherlands,

then use 3rd party DNS service such as cloudflare.

@HalfEatenPie install one to be DNS server of cesidian root =D

I don't think you have to, just use some 3rd part DNS service to make A records could work.

I used to have this and it drove my nuts. I think since I setup a reverse DNS record it started to arrive all well.

EDIT: Oh right its a DNS issue, just read the WHT thread! Sorry

from UK location to google dns.

Nope. His DNS servers are on the same server - which is on the network that's down.

Thanks, I'd email 24kHost, but their website & DNS is on the same network (probably a tiny VPS) at one of their hosting locations.

DNS may also be necessary but the default gateway normally suffices.

monitor everything by dns and ip at the same time.

now I'm using "length" + "recent" dynamic filter to block dns amp attack. it seems work on 2.6.32.* kernel.

Sorry folks, lost a drive at 3am while that should not have caused a load issue is did and the load was creeping up by 1 - 2 every minute, an announcement was put up about this however due to the DNS

Only a Socks Proxy with configured DNS ensures that the whole traffic is going through the VPS. If someone is only using an http proxy all DNS querries and non-http traffic (Flash, Streaming) is using

why its website shows a parked domain for me? something wrong with my DNS?

Check to see if your DNS is working with your server. Check to see why Cloudflare doesn't work with your server. Check Cloudflare's logs. Make sure you have the proper proof before pointing fingers

It is not a DNS problem cause I can't ping IPs either, only the VPS's
