I have a VPS server on which CentOS 6.5 x64 is installed. Kernel version from uname command is 2.6.18-028stab107.
When I want to use iptables rate limiting like in the following command, I got the error message below.
iptables -I INPUT -p tcp --dport 80 -m state --state NEW -m recent --set
iptables: No chain/target/match by that name.
I think required conntrack modules are not installed on system, lsmod command output is empty.
[root@myserver ~]# lsmod
Module Size Used by
I try to load modules like below, and got the errors.
[root@myserver ~]# modprobe ip_conntrack
FATAL: Module ip_conntrack not found.
[root@myserver ~]# modprobe nf_conntrack
FATAL: Module nf_conntrack not found.
Finally, I think, I have to install state and conntrack modules, but cant install because yum search result does not include required packages.
[root@myserver ~]# yum search conntrack

How can install these modules and use my iptables commands given at the top?
