Hi all and tc Gururs
i have patched the IMQ and htb to kernel, but when i do egress filtering,
iam not able to see any traffic
and excusted the following the commands
modprobe imq numdevs=1
tc qdisc add dev imq0 handle 1: root htb default 1
tc class add dev imq0 parent 1: classid 1:1 htb rate 100kbit
tc qdisc add dev imq0 parent 1:1 handle 10: htb default 1
tc class add dev imq0 parent 10: classid 10:10 htb rate 100kbit
tc qdisc add dev imq0 parent 10:10 handle 20: sfq
iptables -t mangle -A POSTROUTING -p tcp --dport 80 -j IMQ
ip link set imq0 up
when i see the Iptables Out Put
[root@xxxxxx root]# iptables -xnvL -t mangle
