From: "Paul Dubinsky" <pdubinsky@xxxxxxxxxx> --8<-- Whenever I run "service ipchains status", Fedora reports "ipchains not compatible with this kernel". Is this true? Iptables works fine and Ipchains seems to start. I'm confused. --8<-- IPChains may appear to work with a 2.4 level kernel. It does not work fully. I'd not trust it after the way it made hash of the rule set I had evolved on 2.2 level kernels. Moving over to IPTables was a pain in the backside. But once I got it done it was simpler and clearer about what was going on. I have all my IPChains functionality and more. Check out http://www.netfilter.org/ for the definative set of documentation collection. I found a couple suitable example set of rules there. One was simple and the other more exhaustive. Both were reasonably well documented. I picked the high security version and setup the specific mods I needed to make it run correctly for my system. The time I spent was well worth the problem. Fedora would be well to simply discontinue automatically installing the rather incomplete ipchains EMULATION. Including it gives a false sense of security and functionality for users. {^_^}
