[bwm-tools-tech] Problems with bwmd

[Gianluca F. <g.f...@io...>]

Hi folks,

After a lot of time searching the web for a badwidth throttling system, I
found bwm_tools and I must admit I simply love this tool. I installed it on
my firewall and it worked perfectly.
This morning I found a bad surprise though, my firewall crashed and all I
have found in the logs are these entries:

Sep  6 09:08:42 zizou bwmd: Failed to ACCEPT packet
Sep  6 09:09:13 zizou last message repeated 1325 times
Sep  6 09:09:15 zizou last message repeated 92 times

I'm running a SuSE Linux 9.2 - kernel 2.6.8-24-smp with bwm_tools vers.
0.2.1 and iptables 1.2.11
My bwmd config is rather simple, I only throttled incoming http:

<firewall>
<traffic>
                 <flow name="http_in" max-rate="64000" burst-rate="64000"
nfmark="100"/>
</traffic>
</firewall>

I'm marking packets coming from the outside interface from port 80 in the
prerouting chain of the mangle table, and enqueing them in the forward
chain.
The only strange thing that I've thought is that since I have set input,
forward and output chain to DROP, maybe I'm missing some rules to allow
traffic to and from the daemon itself.

Anyone got a clue on this?

Any help appreciated.

Thxs,
