Ip Tables Ko Not Found

Posted January 16, 2018 By phil2k.

The problem still exists in the latest version of the kernel selected for a dropbox with Ubuntu 16.

04: #Ubuntu 16.

04 x64 vmlinuz 4.


0-28-generic#, kernel modules becoming somehow #ephemeral# (disappearing after the reboot) + making the floating IP not working anymore:, I’m trying to build a customer Linux kernel (I modified the source code a bit).

The version is 3.


11 and I’m using Ubuntu 14.


However, when doing make modules_install, I find only a few modules are compiled and installed, which makes the module ip_tables does not work well: $ modprobe iptable_nat modprobe: FATAL: Module iptable_nat not found.

, Running Ubuntu Server 16.


06 and recently ran a kernel upgrade to 4.


0-50-generic and now I am completely missing the iptables.

ko module.

It is not located in the /lib/modules section.

And I, I see the following errors in dmesg when insmodding ip_tables.


I found that CONFIG_NETFILTER in kernel config is a boolean – and has to be ‘Y’.

With remaining changes to.

config, my modules still do not load – presumably because some of the symbols (e.


nf_register_*) are part of kernel and not in any external module.

, 05/11/2012 FATAL: Module ip_tables not found.

iptables v1.



1: can’t initialize iptables table `filter’: Table does not exist (do you need to insmod?

) Perhaps iptables or your kernel needs to be upgraded.

I did some reading and it appears that the kernel I am using does not have the module iptables needs to operate.

Can anyone please help?

, Linux , iptables.

root @ xxxx: ~ # iptables -Lmodprobe: FATAL: ip_tables.

21: , Say I have a loop that uses the same variable as one of my interrupts.

This is not specific to any embedded system, more of an implementation question / how different systems handle this issue.

I will be using pseudo-code:ip tables ko not found
