ip rule kernel support

[Mutek]

Hi,

I'd like to set up support for multiple ADSL providers using iproute2, for which I need the ip rule add command in order to create forwarding rules.

When I try to use the ip rule ls command, I get:

bubba2:~# ip rule ls
RTNETLINK answers: Operation not supported
Dump terminated

This suggests that the kernel is missing something. Is there a kernel module which needs installing, or does this need a new kernel?

Many thanks,

Mark

Have you checked iproute is installed as a package?
It is available.

http://packages.debian.org/sid/iproute

Hi,

Yes, it's installed - see the aptitude listing below. My suspicion is that the appropriate kernel options for ip rule (policy tables) were not compiled in, or it's a kernel module I've not spotted. I can do ip route ls, ip addr and so on and all that is working fine.

Aptitude output here:

Description: Professional tools to control the networking in Linux kernels
This is `iproute', the professional set of tools to control the networking behavior in kernels 2.2.x and later.

At least, the options CONFIG_NETLINK and CONFIG_NETLINK_DEV (or CONFIG_RTNETLINK) must be compiled into the running
kernel.

This package is also known as iproute2 upstream and in some documentation.

It seems to me, ip rule is not supported in current kernel.
Any reliable way to fix this?

Yep, +1 for this. We need that option enabled in kernel.

I recompiled the kernel to enable this feature too, but it would be nice to have it in the official kernel also. The option is IP_ADVANCED_ROUTER.
