iptables masquerading no longer seems to work - Missing module in kernel? - marky - 11th Feb, 2015 01:36 AM

Hi all,

Since last night my iptables masquerading seems to throw an error. I did indeed perform an update yesterday, but I couldn't fix the issue by rolling back.

Today I set up a completely fresh installation of xbian and am still getting the same error.
When I try setting up masquerading with iptables for my VPN using this command:

Code:

iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -i eth0 -j MASQUERADE

my raspi returns this error message:
iptables v1.4.14: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

i am currently running this configuration:

Code:

root@xbian ~ # uname -a

Linux xbian 3.17.7-ck2+ #3 PREEMPT Sat Jan 17 15:08:48 CET 2015 armv6l GNU/Linux

root@xbian ~ # lsmod

Module                  Size  Used by

tun                    16763  2

iptable_filter           980  0

cdc_acm                14899  2

frandom                 3547  1

vchiq                 195204  2

I'd be happy to give more info, but for now I don't know what else to do, I loaded a dozen modules so far and couldn't find a viable solution googling around.. Sad

Anyone having the same problem?
Or does anyone have a solution?

Thanks a lot!

Mind to report it here? https://github.com/xbianonpi/xbian/issues - please report your previous kernel version (check the last entries in /var/log/apt/history.log if unsure).
I think the relevant kernel module has just been disabled by mistake.

done, thank you.

I'm afraid it'll take a while till this is passed down and ends up fixed in one of the next releases if it's the case that the module is missing Sad

Kernel module was missing, quick fix for everyone having the same problem with kernel 3.17.7-ck2+ is to downgrade to xbian-package-kernel_3.16.5-ck2+-1420117998 (available in the staging repo).

Looks like the setting will be changed in future versions.

Thanks. Would you mind edit prefix of your thread to [Solved]?

Hello there,

I'm new to Xbian and I just did a fresh new installation, Can you explain me how to downgrade the kernel?

Thanks.

The new kernel should already be out there and should be fixed. I haven't tried it yet, so here's what I did to move back to an older version:

Code:

wget http://apt.xbian.org/pool/staging/rpi-wheezy/x/xbian-package-kernel/xbian-package-kernel_3.16.5-ck2+-1420117998_armhf.deb

dpkg -i xbian-package-kernel_3.16.5-ck2+-1420117998_armhf.deb

reboot

after the reboot, you should have moved back to version 3.16.5.
