freeradius 限制rp-pppoe伺服器每一個連接配接的帶寬

限制rp-pppoe伺服器每一個連接配接的帶寬

關鍵就是使用一個腳本，在ppp建立和取消連接配接的時候調用tc使用htb對每一個ppp連接配接的帶寬進行限制。

調用的腳本讀取/var/run/radattr.pppx中的radius屬性，限制帶寬。

use the roaringpenguin rp pppoe-server and limit the bandwidth per 

interface with this script:

(im using freeradius plugins too, thats the reason of the 

/var/run/radattr.pppx file)

(/etc/ppp/ip-up.d/0pppx_up)

#!/bin/sh

DOWN=`cat /var/run/radattr.$1 | grep 'RP-Downstream-Speed-Limit' | cut -d ' 

' -f 2`

UP=`cat /var/run/radattr.$1 | grep 'RP-Upstream-Speed-Limit' | cut -d ' ' -f 

2`

# limit Download Bandwidth with a simple htb qdisc and class (add QoS 

here?...)

/sbin/tc qdisc add dev $1 root handle 1: htb default 1

/sbin/tc class add dev $1 parent 1: classid 1:1 htb rate ${DOWN}kbit ceil 

${DOWN}kbit burst 1540

/sbin/tc qdisc add dev $1 handle ffff: ingress

/sbin/tc filter add dev $1 parent ffff: protocol ip prio 50 u32 \

     match ip src 0.0.0.0/0 \

     police rate ${UP}kbit burst 10k drop flowid :1

and have another script for deleting the rules 

(/etc/ppp/ip-down.d/0pppx_down):

#!/bin/sh

/sbin/tc qdisc del dev $1 root

/sbin/tc qdisc del dev $1 ingress

ppp executes this scripts each time an interface gets up or down.
