伊爱GPRS服务系统流量控制（二）

在/etc/rc.d/init.d/ 中建立脚本文件 TC2，不可以命名为TC，其他名称都可以，内容如下

#。。。。。。。。。。。。。。。。。。。。。
#!/bin/bash
#Set the following values to somewhat lesss than your actual download and uplink speed.
DOWNLINK=40960
UPLINK=40960
#clean existing down and uplink qdiscs,put the errors to /var/log/htb_log
tc qdisc del dev eth0 root 2> /dev/null > /dev/null
tc qdisc del dev eth0 ingress 2> /dev/null > /dev/null
tc qdisc del dev eth1 root 2> /dev/null > /dev/null

以ROOT身份登陆，

chomod +x /etc/rc.d/init.d/tc3
sh /etc/rc.d/init.d/tc3

   本示列，以40M带宽进行分配。一类包括GPRS服务保证20M带宽。可根据实际情况修改DOWNLINK ，UPLINK的值，具体分配带宽根据实际情况进行调整。
TC用法具体可参考网上其他资料，本脚本在RH9（需升级HTB），FC4，Centos4.2下正常工作。
