iptables HUH?
| Posted by dannycg, 03-12-2008, 11:39 AM | | Hey.
On my new unmanaged VPS i keep getting mass emails sent to me saying -
iptables v1.2.11: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
Im a bit of a n00b when it comes to unmanaged servers, just wondering if anyone knows whats wrong and how to fix.
Thanks!

lsmod to see if iptables module is loaded
and
iptables --list to see what tables are loaded.

load the respective modules. The filter table is responsible for all packet filtering, so without it you also don't have any firewall running and thus no protection against any attacks.

lsmod | grep ip

if so you may want to install "base" (if its Centos Based)
yum groupinstall base
Thanks
