This question already has an answer here:
I had a CentOS6.7 with OpenVZ. Now, I just uninstalled OpenVZ and start using Plain CentOS6.7. Due to some difficulties for using cPanel in OpenVZ.
I noticed one problem when install csf in my plain server. Error: iptables: No chain/target/match by that name.
this error comes only when using -m state option with iptables.
Message Log : FATAL: Error inserting xt_state (/lib/modules/2.6.32-358.el6.x86_64/kernel/net/netfilter/xt_state.ko): Unknown symbol in module, or unknown parameter
Dmesg Log : nf_conntrack: Unknown parameter `ip_conntrack_disable_ve0'
Can someone give any idea and please share some troubleshooting link if you have ?.
