DNS DDoS Attacks
| Posted by HR Development, 03-09-2008, 05:59 AM |
| Hello,
I have a VPS that's on the awknet network and I'm receiving DNS DDoS and I don't think they have anything to stop these attacks, how can I prevent these?
Thanks,
HRDev

| Well.. you COULD recompile BIND from source to not send NXDOMAIN reply for non-local domains, but that's a bit extreme. Tried logging what they're attacking? tcpdump -vvv -nn dst port 53 -s 1700

| Well, the attack is not happening right now so I can't, but when it does happen i'll run that, is there any other alternatives to compiling BIND from source?

| try using an external dns service, they are usually better equipped for these things. I have had some clients that was getting my dns hit hard use freedns.org and issues were resolved.
