Hello security-list! I'd like to implement the following: To avoid DDoS-attacks I'd like to set priorities for certain network-services. I once read an article on securityfocus.com about how to for example set up that http-traffic is more important than DNS-traffic. It's possible using the ipchains. But unfortunately I can't find that article anymore where this is explained. So I hope for your assistance with this problem. Does anyone have a good description on how to set priorities? Thanks in advance, A. Achtzehn -- -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GCS/CM/IT/P d@ s: !a C++(+) UL++++$ P++ L+++(++++)@ E---- W+++ N+ o?
