Hi, sorry if this has been asked before but will using iptables to randomize source ports further help prevent cache poison? I have a Bind 9 server that is and authoritative/cache server. Where can I find some examples of iptables rules being used with random port/rate limits? I tried using iptables with the random options but I get, iptables v1.2.11: Unknown arg `--random'.
Using BIND 9.4.3b2 with iptables v1.2.11 on Centos 2.6.9-67.0.20.ELsmp. Thanks, Paul
