云立方购买的服务器 不需要 配置 拨号 ,直接使用命令拨号 

云立方 使用

adsl-start 拨号
adsl-stop 停止

下面不是云立方使用

pppoe-start 拨号
pppoe-stop  断开拨号
pppoe-status 拨号连接状态

----------------

TinyProxy 安装

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
yum update
yum install -y tinyproxy
vim /etc/tinyproxy/tinyproxy.conf 
--
　　修改配置文件

　　Port 8888 #预设是8888 Port,你可以更改
　　Allow 127.0.0.1 #将127.0.0.1改成你自己的IP
　　#例如你的IP 是1.2.3.4,你改成Allow 1.2.3.4,那只有你才可以连上这个Proxy
　　#若你想任何IP都可以脸到Proxy在Allow前面打#注释

启动

service tinyproxy start

查看端口

netstat -tnlp

下面是 使用 python 控制 拨号服务器
