iptables table 'mangle' does not exist #38

Closed irfanka closed 6 years ago

irfanka commented 6 years ago

Hi.

I'm trying to use the Nitrogen6Q_W board as a captive portal hotspot. I'm using the "Ubuntu Xenial for i.MX boards (August 2016, kernel 4.1.15)" image that I got off of the BoundaryDevices website, and I've installed hostapd, coovachilli, and freeradius.

However, CoovaChilli is spewing this error when it tries to set up it's iptables rules:

iptables: No chain/target/match by that name. iptables v1.6.0: can't initialize iptables table 'mangle': Table does not exist (do you need insmod?) Perhaps iptables or your kernel needs to be upgraded.

I've also noticed that the 'nat' table is missing too.

Do I need to recompile the kernel to enable these? Are they supported at all? If so, do you have any hints which flags I should change during config?

Also, is it better if I use the kernel tree from the boundary-imx_4.1.15_2.0.0_ga branch, or should I stick with 1.0.0?

Thanks,

Hi,

Iptables support was added to default configuration a few weeks ago. https://github.com/boundarydevices/linux-imx6/commit/a5be86df

Are you sure your system is up to date?

Please apt update/upgrade, should work.

Regards, Gary

Well, I did already apt update/upgrade, but I still get the same error from coovachilli/iptables.

Do I need to modprobe something, maybe?

irfanka commented 6 years ago

I tried modprobe iptable_nat - and that worked, so the nat table is in fact now available.

However, the iptable_mangle module does not exist, and looking at a5be86df I see that +CONFIG_NFT_NAT=m, CONFIG_IP_NF_NAT=m etc. were added, but nothing related to MANGLE.

Also, please don't close the issues so eagerly.

Hi,

Sorry but I've closed the issue because this type of request is OS-related (not an issue per say) so we recommend using the blog post comments for that: https://boundarydevices.com/ubuntu-xenial-mx67-boards-august-2016-kernel-4-1-15/

As for mangle, you can re-build the kernel with the option you need following this blog post: https://boundarydevices.com/customizing-ubuntudebian-kernels/
