[RP-PPPoE] radattr.so cant receive values from radius

[Mike Tesliuk]

this is my script to set the bandwidth

#!/bin/bash
#PPP_IFACE PPP_TTY PPP_SPEED PPP_LOCAL PPP_REMOTE PPP_IPPARAM

UPB="64kbit"
DOB="64kbit"

/sbin/tc qdisc add dev $PPP_IFACE root handle 1: htb default 30
/sbin/tc class add dev $PPP_IFACE parent 1: classid 1:1 htb rate $UPB
/sbin/tc class add dev $PPP_IFACE parent 1: classid 1:2 htb rate $DOB
/sbin/tc filter add dev $PPP_IFACE protocol ip parent 1:0 prio 1 u32
match ip dst $PPP_REMOTE/32 flowid 1:1
/sbin/tc filter add dev $PPP_IFACE protocol ip parent 1:0 prio 1 u32
match ip src $PPP_REMOTE/32 flowid 1:2


look on this file, i have a UPB e DOB variable, this is static for
now, i want to get the value of the radattr file to get this function
dynamic.


when i do a freeradius -X i get this


rlm_sql (sql): Reserving sql socket id: 2
