dear All,Patch the kernel yourself so you are sure you have the latest htb.
I'm a new student and my job is too shapping bandwith for our campus
faculty network. I want to implement htb with Redhat-9.0 distro.
does this distro kernel support htb and tc good ? or i should apply some
patch or upgrade kernel ?

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.
