Re: Bandwidth Throttling?

Ok, I found some info using google 
(http://oob.freeshell.org/nzwireless/nocat1.html) about NoCat 
throttling, and I've set up values in my throttle.fw, and made it 
executable.  But, as far as I can tell, bandwidth throttling isn't 
happening.  It doesn't seem to me that throttle.fw is even getting run 
by NoCat.

If I do # tc -s qdisc, this is all it shows:
[root@nocatgw bin]# tc -s qdisc
qdisc pfifo_fast 0: dev eth0 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 
1 1 1
 Sent 104 bytes 1 pkt (dropped 0, overlimits 0 requeues 0)
 rate 0bit 0pps backlog 0b 0p requeues 0
qdisc pfifo_fast 0: dev eth1 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 
1 1 1
 Sent 11856 bytes 96 pkt (dropped 0, overlimits 0 requeues 0)
 rate 0bit 0pps backlog 0b 0p requeues 0

I edited throttle.fw so I could run it manually (assigned InternalDevice 
and ExternalDevice varialbes in the script), and after I run it 
manually, I see something different:
[root@nocatgw bin]# tc -s qdisc

However, I still don't see anything throttled on a logged in client.  I 
go and do a speed test, and I'm still getting full speed.

So I guess I have two issues:  NoCat doesn't seem to be executing the 
throttle.fw script, and even when I execute it manually, it doesn't seem 
to be doing anything.

Anyone have any ideas?

Here's the top of my throttle.fw: (I haven't changed anything below this 
part)

# throttle.fw: Set the bandwidth policy, based on FWMARK
#
# Set your limits in the defines at the top.  Someday this will be
# integrated into the nocat.conf...
#
##

# Note: your PATH is inherited from the gateway process
#

InternalDevice="eth1"
ExternalDevice="eth0"

TOTAL_DOWN=45mbit
TOTAL_UP=45mbit

OWNER_DOWN=45mbit       # fw mark 1
OWNER_UP=45mbit
OWNER_OPTIONS=""

COOP_DOWN=1536kbit              # fw mark 2
COOP_UP=1536kbit
COOP_OPTIONS=""

PUBLIC_DOWN=256kbit     # fw mark 3
PUBLIC_UP=256kbit
PUBLIC_OPTIONS="bounded"

OPTIONS="allot 1514 maxburst 20 avpkt 1000 prio 1"
METHOD="sfq quantum 1514b perturb 15"


Any ideas?  Thanx!
