dear all, i'm compiling portsentry on my system which has a 2.4.0-test9 kernel. when i compiled the kernel, i didn't see an ipchains options; it seems to have been replaced by something called netfilter. just to make sure -- did i simply not see ipchains or was it really replaced by netfilter? i'd like to learn how to drop packets coming from a particular host -- is there a netfilter howto yet? i didn't see anything on LDP. pete
