iptables: Table does not exist (do you need to insmod?)

I have problem with my firewall. Everything was ok till yestarday. I restarted my server and when I try to load firewall rules it shwos like that :

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.

on command

modprobe ip_tables :

modprobe: error while loading shared libraries: libc.so.6: cannot open shared object file: Operation not permitted

output on comand :

grep -i iptables /boot/config-`uname -r`

CONFIG_IP_NF_IPTABLES=m
CONFIG_IP6_NF_IPTABLES=m

Can sombody help me what to do ?

 

I think you libc package is broken which is causing modprobe not to work, which flavor of linux are you running ?

What is the output of

Code:

ldd $(which modprobe)

 

Operation not permitted

this is a message when i dont have root privileges

 

Run it with root privileges.
