在Ubuntu服务器上的QOS

我想在ubuntu服务器上运行下面的脚本。 eth1是NAT接口，而eth2是具有静态公有IP的WAN接口：

TCA="tc class add dev eth2" TFA="tc filter add dev eth2" TQA="tc qdisc add dev eth2" SFQ="sfq perturb 10" tc qdisc del dev eth2 root tc qdisc add dev eth2 root handle 1: htb tc class add dev eth2 parent 1: classid 1:1 htb rate 4560kbit $TCA parent 1:1 classid 1:10 htb rate 2280kbit ceil 4560kbit prio 0 $TCA parent 1:1 classid 1:11 htb rate 912kbit ceil 4560kbit prio 1 $TCA parent 1:1 classid 1:12 htb rate 912kbit ceil 4560kbit prio 2 $TCA parent 1:1 classid 1:13 htb rate 10kbit ceil 10kbit prio 4 $TQA parent 1:10 handle 10: $SFQ $TQA parent 1:11 handle 11: $SFQ $TQA parent 1:12 handle 12: $SFQ $TQA parent 1:13 handle 13: $SFQ $TFA parent 1:0 prio 0 protocol ip handle 10 fw flowid 1:10 $TFA parent 1:0 prio 1 protocol ip handle 11 fw flowid 1:11 $TFA parent 1:0 prio 2 protocol ip handle 12 fw flowid 1:12 $TFA parent 1:0 prio 4 protocol ip handle 13 fw flowid 1:13 iptables -t mangle -A POSTROUTING -p tcp --sport 80 -j MARK --set-mark 10 iptables -t mangle -A POSTROUTING -p tcp --sport 443 -j MARK --set-mark 11 iptables -t mangle -A POSTROUTING -p tcp --sport 995 -j MARK --set-mark 12 iptables -t mangle -A POSTROUTING -p tcp --sport 1024:65535 -j MARK --set-mark 13 TCAU="tc class add dev imq0" TFAU="tc filter add dev imq0" TQAU="tc qdisc add dev imq0" modprobe imq modprobe ipt_IMQ ip link set imq0 up tc qdisc del dev imq0 root tc qdisc add dev imq0 root handle 1: htb tc class add dev imq0 parent 1: classid 1:1 htb rate 4560kbit $TCAU parent 1:1 classid 1:13 htb rate 10kbit ceil 10kbit prio 4 $TQAU parent 1:13 handle 13: $SFQ $TFAU parent 1:0 prio 4 protocol ip handle 13 fw flowid 1:13 iptables -t mangle -A PREROUTING -p tcp --dport 1024:65535 -j MARK --set-mark 13 iptables -t mangle -A PREROUTING -j IMQ --todev 0 

当我做modprobe imq和modprobe ipt_IMQ我得到错误的kernel module is not found 。 有什么办法可以使这个脚本在Ubuntu的服务器上工作？
