DNS dDos Attack!

  • From: Dan Armstrong

I am sorry if this has come up before, but it seems that one of our name

servers is under some sort of dDos attack.  It seems to be receiving
millions of queries form spoofed IPs, and it is spending all of it's
time sending back icmp unreachables.

It is running bind 4.31 under BSD 4.62STABLE

Help!

Thanks,
Dan.
