校园网来l2tp vpn连接 出现问题了。。。

[gaozhimin22]

用ifconfig ppp0查看
‘出现 ppp0 Link encap:点对点协议

停止先前启动的 xl2tpd

# /etc/init.d/xl2tpd stop

再以非 daemon 方式启动之

# xl2tpd -D

然后在另外一个控制台向 l2tpd 发送命令

# echo "c vpn" > /var/run/xl2tpd/l2tp-control

出现 l2tpd[8033]: init_network: Unable to bind socket: Address already in use. Terminating.

是什么问题？？那里出错了那

重启后又重新调试下出现 sudo xl2tpd -D

是l2tp的bug，而我在openwrt里的l2tp可以正常拨号。
