I'm pretty sure those changes are from the kernel devs - you would need to ask the lkml people. if it is from the gentoo guys, I find it less annoying than the default editor being nano instead of vi... :) On Nov 13, 2007 11:21 PM, Walter Dnes [EMAIL PROTECTED] wrote: I've been running Gentoo for a few years, and I remember earlier versions of iptables, where everything was on one page.

[gentoo-user] OT - Need help enabling iptables support in kernel
I have a big problem. I've asked this question here in the past, and have never gotten a straight answer. I use ipkungfu as my firewall sofware. I noticed yesterday when I had to reboot my server box that ipkungfu wasn't starting. baby ~ # /etc/init.d/ipkungfu restart * Starting ipkungfu ... Your kernel lacks stateful matching, this would break this script. Aborting. * Failed to start ipkungfu [ !! ] I rebuilt my kernel (2.6.20-hardened-r6) five or six times yesterday and this morning, enabling literally every single option under netfilter in the kernel config. I reboot each time only to find that the options have not in fact been enabled. Doing a google search for this only returns references to my previous emails. I'm panicking right now. What should I do? I just want my firewall back. Up until the reboot of a couple of days ago it worked, and I'm not sure what's changed. Please help.
