PATH=/sbin:/usr/sbin:/bin:/usr/bin
export PATH

LOGDEVICE=$6
REALDEVICE=$1

/etc/ppp/ip-up.ipv6to4 ${LOGDEVICE}

[ -x /etc/ppp/ip-up.local ] && /etc/ppp/ip-up.local "$@"

echo "$PEERNAME 分配IP:$5 登錄IP:$6 登錄時間:`date -d today +%F_%T`" >> /var/log/pptpd.log

exit 0

2、配置/etc/ppp/ip-down

#!/bin/bash

[ -x /etc/ppp/ip-down.local ] && /etc/ppp/ip-down.local "$@"

/etc/sysconfig/network-scripts/ifdown-post --realdevice ${REALDEVICE} \
    ifcfg-${LOGDEVICE}

echo "$PEERNAME 下線IP:$6 下線時間:`date -d today +%F_%T`" >> /var/log/pptpd.log
