Incoming traffic [attack?] Recently a huge amount of incoming traffic is going to our server. We can't figure out where it is coming from neither where it is going to since the ip that receives all the traffic has no domains assigned - just an empty ip on eth0. (Addition: one client has this ip assigned to him, and one domain with no hosting configured.) Disabling Apache or BIND Service helps. Any help or suggestions would be greatly appreciated. Thank you.
