Hi All..

i'm already start to build shapping with RH-9.0 and htb 
(htb.init-v0.8.4..actually), tc is support htb
my topology like this
ISP---eth1-----eth0---LAN
   512kbps      
output from tc.

When i tried to check with iperf from 172.16.0.228 (classid 10:20 with 
256kbps rate).

$ ./iperf -c 172.16.0.232
------------------------------------------------------------
Client connecting to 172.16.0.232, TCP port 5001

I didnt see bandwith rate that i expected..is there something wrong with 
my config..
please help me....
