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.
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.
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:
