Configure htb.init or cbq.init

Hi !

I would need some help to configure htb.init or cbq.init.
Actually, I would like to limit outgoing trafic of Samba, so that the
downloads don't take 100% of my bandwith. That's why I tried htb on
port 139 :
I wrote those 3 files in /etc/sysconfig/htb
=eth0=
DEFAULT=30
R2Q=100

=eth0-2.root=
RATE=1Mbit
BURST=15k

=eth0-2:10.samba=
RATE=500k
BURST=15k
LEAF=sfq
RULE=*:139,

But it doesn't work, I still get 10Mo/sec when I transfer files...
"htb.init stats" gives me "(dropped 0, overlimits 0)"
I don't get what's going on

Thanks for your help !
