[LARTC] TC filter error

[LARTC] TC filter error

[-- Attachment #1.1: Type: text/plain, Size: 866 bytes --]

When I enter the following, 

 

tc filter add dev eth0 parent 1:0 protocol ip prio 0 u32 match ip src
192.168.0.61 flowid 1:10

 

Iget this response:

RTNETLINK answers: Invalid argument

We have an error talking to the kernel

 

The qdiscs add fine, and show as expected, but I can't for the life of me
get the filter to apply.

 

Using Gentoo w/kernel 2.6.21.3. IPTABLES running as a basic NAT gateway. My
whole goal hinges on getting the filter to work, then I might understand
what the heck is going on with this stuff. I've added every
marking/netfilter kernel option I can find, both as a module and native. No
matter what I add or take away, I get the same error when I try to add the
filter.

 

It's probably one of those "simple" things, but I'm stumped. Please help, an
additional 200 connections is crimpling us at the moment!

 

Regards,

Sean

I can't see anything wrong with that that should throw an error.
prio 1 is the top prio for filters, but it shouldn't matter.

does it work on something simple like -

tc qdisc del dev eth0 root &>/dev/null

tc qdisc add dev eth0 handle 1:0 root prio
tc filter add dev eth0 parent 1:0 protocol ip prio 0 u32 match ip src 
192.168.0.61 flowid 1:3

Andy.
