Ubuntu IPv6 pppoe服务器搭建(基于Kea DHCP Server V1.2.0)

1、安装pppoe服务器
sudo apt-get install pppoe

2、配置pppoe服务器
(1) 修改/etc/ppp/chap-secrets，增加拨号用户名，密码：
增加一行："chap"   *   "chap"    *

(2) 新增/etc/ppp/pppoe-server-options
增加一行：+ipv6(加号不能省略，否则拨号失败)

3、启动pppoe服务器
pppoe-server -I eth0 -L 10.10.10.49  -R 10.10.10.50  -N 50

注：

• chap认证方式这样配置即可，pap还没有验证。
• 按此配置客户端获取的只是link local地址。

4、启动RADVD和重启kea

• 将/usr/share/doc/ppp/examples/scripts/ipv6-up.sample 拷贝为/etc/ppp/ipv6-up.d/ipv6-up，并修改如下：

#!/bin/sh## This script is called with the following parameters:# interface tty speed local-address remote-address ipparam## Start router advertisements on this link.# Based on radvd 0.5.0 behaviourDEVICE="$1"CFGFILE="/etc/radvd.conf-$DEVICE"PIDFILE="/var/run/radvd/radvd-$DEVICE.pid"EXEFILE="/usr/sbin/radvd"LOGFILE="/var/log/pppoe-server"GenerateRadvdConfig(){    echo  "[`date +%H`:`date +%M`:`date +%S`][$0] generate radvd config for $DEVICE" >> "$LOGFILE"    cp /etc/radvd.conf "$CFGFILE"    if [ $? -eq 0 ];then        sed -i "s/eno1/$DEVICE/g"  "$CFGFILE"    else        echo  "[`date +%H`:`date +%M`:`date +%S`][$0] cp /etc/radvd.conf failed" >>  "$LOGFILE"    fi}RunRadvd(){    if [ -x "$EXEFILE" -a -f "$CFGFILE" ]; then        echo  "[`date +%H`:`date +%M`:`date +%S`][$0] $EXEFILE -u radvd -C $CFGFILE -p $PIDFILE " >>  "$LOGFILE"        "$EXEFILE" -u radvd -C "$CFGFILE" -p "$PIDFILE"    else        echo  "[`date +%H`:`date +%M`:`date +%S`][$0] $EXEFILE is not executable, or $CFGFILE is not existed " >>  "$LOGFILE"    fi}ModifyKeaConfig(){    local configPath="/usr/local/etc/kea/kea.conf"    local lineNum=`grep \"interface\":\"eno1\" "$configPath"  -n |cut -d : -f 1`    local samplePath="/etc/ppp/ipv6-up.d/kea_pool.sample"    #配置地址池    sed -i "s/eno1/$DEVICE/g" "$samplePath"    sed -i "$lineNum r $samplePath" "$configPath"    sed -i "s/$DEVICE/eno1/g" "$samplePath"}##################################################### main #####################################echo  "[`date +%H`:`date +%M`:`date +%S`][$0] $DEVICE up" >>  "$LOGFILE"#1.生成radvd配置，并启动radvd进程GenerateRadvdConfigRunRadvd#2.修改kea-dhcp6的配置，并重启服务ModifyKeaConfigkeactrl stopkeactrl start

• 在/etc/ppp/ipv6-up.d/下新建文件kea_pool.sample，并修改为：

        },    {      "subnet": "2001:10:10:10::/64",      "pools": [ { "pool": "2001:10:10:10::1-2001:10:10:10::ffff" } ],      "pd-pools":       [        {          "prefix": "3000:6666:6666:6666::",          "prefix-len": 48,          "delegated-len": 64        }      ],      "interface":"eno1"

• 将/usr/share/doc/ppp/examples/scripts/ipv6-down.sample拷贝为/etc/ppp/ipv6-down.d/ipv6-down，并修改为：

  #!/bin/sh## This script is called with the following parameters:# interface tty speed local-address remote-address ipparam## Kill the router advertisement daemon on this interface.# The killing procedure is copied from RedHat 6.0 initscripts.DEVICE="$1"PIDFILE="/var/run/radvd/radvd-$DEVICE.pid"CFGFILE="/etc/radvd.conf-$DEVICE"LOGFILE="/var/log/pppoe-server"StopRadvd(){    local PID="$(cat "$PIDFILE")"    if [ "$PID" != "" ]; then        echo  "[`date +%H`:`date +%M`:`date +%S`][$0] kill -TERM $PID" >> "$LOGFILE"        kill -TERM "$PID"    fi    rm -f "$PIDFILE"    rm -f "$CFGFILE"}ModifyKeaConfig(){    local configPath="/usr/local/etc/kea/kea.conf"    local endLineNum=`grep \"interface\":\""$DEVICE"\" "$configPath"  -n |cut -d : -f 1`    local startLineNum=`expr $endLineNum - 12`     # 删除地址池    sed -i "${startLineNum},${endLineNum}d" "$configPath"}##################################################### main #####################################echo  "[`date +%H`:`date +%M`:`date +%S`][$0] $DEVICE down" >> "$LOGFILE"StopRadvdModifyKeaConfigkeactrl stopkeactrl start
