[LARTC] simple htb script which does not work

[Ludovic Drolez <ludovic.drolez@freealter.com>]

Hi !

I'm using the htb.init script to do simple things with my adsl
connection:
- uploads through a VPN (port 2001 used) can use all BW (128Kbits) 
(rate\x15kbps, ceil\x16kbps), class 10
- and others have only 8 kbits but can take all the BW if there is no
VPN activity. (rate=1kbps, ceil\x16kps), class 20

But, BW sharing does not seem to work, and if I make 2 uploads, one
through the VPN, the other with ssh on the net, I get 8kbps/8kbps
instead of 15kbps/1kbps.

Some stats show that packets are filtered the right way.

here's this simple script: (got it with 'htb.init compile')

tc qdisc del dev ppp0 root
tc qdisc add dev ppp0 root handle 1 htb default 20

tc class add dev ppp0 parent 1: classid 1:2 htb rate 16kbps mtu 1492

tc class add dev ppp0 parent 1:2 classid 1:10 htb rate 15kbps ceil 
16kbps prio 1 mtu 1492
tc qdisc add dev ppp0 parent 1:10 handle 10 sfq perturb 10
tc filter add dev ppp0 parent 1:0 protocol ip prio 100 u32 match ip 
dport 2001 0xffff classid 1:10
tc filter add dev ppp0 parent 1:0 protocol ip prio 100 u32 match ip 
sport 2001 0xffff classid 1:10

tc class add dev ppp0 parent 1:2 classid 1:20 htb rate 1kbps ceil 16kbps 
prio 5 mtu 1492
tc qdisc add dev ppp0 parent 1:20 handle 20 sfq perturb 10



Any idea ?


Cheers,
