If you already have iptables module loaded you will be unable to use ipchains (and visa versa)

> lsmod

will show you what modules are loaded.

MFSRich, are there real security admins who use modules for firewalls (except for testing)? I can't believe. :-O

i guess by default, ipchains is not enabled in newer redhats.  make you own kernel, skip out on iptables, turn on all the ipchains options, and it should be good  (that's assuming you're trying to use an old ipchains script, not trying to build a new firewall, in which case, just use iptables, search for IPTABLES HOWTO in this case)

Actually, the ipchains that you see on the newer kernel versions is just an emulator module that reads ipchains style rulesets and feeds them into iptables.  It only "looks" like ipchains :-> ....   If you want to use the iptables emulator, you will need to set it to startup at boot (chkconfig ipchains --level 345 on).  Then run "insmod ipchains" to get it started.

#insmod ipchains
would fix the original problem.
Moving the ruleset to iptables is an exercise for the reader.
(and <replace></replace> is better written as s/// ;)).

hello

you must compile your "noyau" (it's a french word i don't know what it mean in english)
For it download the new "noyau" for your linux
and recompile it; during that active IPchains
