1.安裝l2tpd
sudo yum install l2tpd
2.配置文件
/etc/xl2tpd/xl2tpd.conf
port = 1701 ; * Bind to port 1701
access control = yes ; * Refuse connections without IP match
rand source = dev ; Source for entropy for random
[lac zju]
lns = 10.5.1.9 ; * Who is our LNS?
redial = yes ; * Redial if disconnected?
redial timeout = 3 ; * Wait n seconds between redials

3.啟動xl2tpd
sudo service start xl2tpd
或者
sudo /etc/rc.d/init.d/xl2tpd start
4.連接
sudo echo "d zju">/var/run/xl2tpd/l2tp-control
#這裡的zju要和配置文件中的的lac 後面的字節一樣
5.查看是否連接
ip addr show | grep 'inet.*ppp'
有輸出就是連接上了
6.設置路由
ip route add default dev ppp0
6.斷開
sudo echo "d zju">/var/run/xl2tpd/l2tp-control
