yes, I'm using "iptables start" from /etc/rc.d/init.d/ directories. The contents of the /etc/sysconfig/iptables at the moment is just : -P INPUT DROP !!! which is why I can't understand why I'm having problems. I did have some more comprehensive rules in there ported from an old ipchains setup, but whittled it down to that to diagnose this problem. With regards kernelness, to quote myself from my earlier post: > > Now, I issued `lsmod` and I have both "iptable_filter" and "ip_tables" > > modules loaded. ..and that's it, no other modules loaded; which is what I expect as I'm not using the `nat', `masq' or other tables. I'll let you know on the iptables-save shortly. -----Original Message----- From: Ben Russo [mailto:ben@umialumni.com] Sent: 27 November 2002 14:54 To: Sam Pointer Cc: netfilter@lists.netfilter.org Subject: RE: can't initialize iptables table `' OK, when you say "initialize iptables" do you mean that you are using the standard RedHat system V init script called "/etc/rc.d/init.d/iptables" ? If so what is the content of your /etc/sysconfig/iptables? That might be the problem there. When you do an iptables-save what do you see? It doesn't really feel like a kernel/modules related issue, but you lean in that direction, so.... when you type "lsmod" what do you see? On one of my Linux firewalls I see these ipt related modules loaded: ipt_state 1152 25 (autoclean) ipt_MASQUERADE 1824 5 (autoclean) iptable_nat 18452 0 (autoclean) [ipt_MASQUERADE] ip_conntrack 17068 2 (autoclean) [ipt_state ipt_MASQUERADE iptable_nat] iptable_mangle 2272 0 (autoclean) (unused) iptable_filter 2272 0 (autoclean) (unused) ip_tables 11424 7 [ipt_state ipt_MASQUERADE iptable_nat iptable_mangle iptable_filter] Maybe try running "depmod -a" and then reruning the "modprobe ip_tables" On Wed, 2002-11-27 at 06:02, Sam Pointer wrote: > No I didn't custom compile the kernel and the distro is the latest one from > the ftp site at RedHat.
