[Fwd: QoS]
I'm preparing a script using iptables2, (using cbq)
how can i see if packets are well marked?
after having marked some packets, i want to mark remaining packets with
a default mark. the way i do it is: mark all the packet with the default
mark before applying rules to remark specific packet.
Is it a good way to do it?

why lots of packets are going in class root?
