Ubuntu命令行下VPN连接与使用  

2010-11-04 12:05:30|  分类:Ubuntu|  标签:|举报|字号 订阅


1)先安装VPN客户端     
     sudo
apt-get install pptp-linux

2)命令行下拨号连接VPN服务器
     sudo
pptpsetup --create testvpn --server 123.45.67.88 --username kk --password fku --encrypt --start

     –create           后的是创建的连接名称,可以为任意名称;
     –server           后接的是vpn服务器的IP;
     –username     是用户名
     –password      是密码,在这也可以没这个参数,命令稍后会自动询问。这样可以保证账号安全
     –encrypt         是表示需要加密,不必指定加密方式,命令会读取配置文件中的加密方式
     –start              是表示创建连接完后马上连接,如果你不想连,就不写


3)以后要连接VPN或断开VPN

     pon testvpn    <--  VPN的“连接名称"

     poff                <-- 断开VPN连接


4)全部流量走VPN通道

     # 把下面两行加入 /etc/ppp/ip-up 中或者直接命令行输入也行,删除默认网关及把 VPN 服务器作为默认网关,也就是改变路由策略,把所以传输流量通过 VPN 线路来走。

    #route add default gw 192.168.0.1

    #route del default gw 原来的网关 // 原来的默认网关地址可通过 route 命令来获取

Ubuntu通过PPTP协议使用VPN

操作系统实用工具系列文章,将介绍基于Linux ubuntu的各种工具软件的配置和使用。有些工具大家早已耳熟能详,有些工具经常用到但确依然陌生。我将记录我在使用操作系统时,安装及配置工具上面的一些方法,把使用心得记录下来也便于自己的以后查找和回忆。

前言

GFW给大家的生活事带来了各种不便,只有靠我们自己才能改变这种不便。像facebook, twitter, youtube, google+, bitbucket, slideside…. 这些世界知名的网站,我们都没有办法直接访问,有时候你很难联想到为什么要屏蔽这些网站。特别是纯技术社区!

不过我们也有很多的技术,可以穿越这条封锁线。今天我们聊一下,ubuntu通过PPTP协议使用VPN(Virtual Private Network),如何看到外面的世界。

关于PPTP的服务器端配置:请参考 在Ubuntu上安装PPTP VPN服务 文章
win7通过PPTP协议使用VPN:请参考 win7通过PPTP协议使用VPN 文章

目录

  1. 获得VPN账号
  2. ubuntu客户端界面配置
  3. ubuntu命令行配置
  4. 看看外面的世界youtube

1. 获得VPN账号

当你有了基于PPTP协议的VPN账号后,怎么在ubuntu中配置!
VPN账号包括3个部分:IP,用户名,密码

比如:(只为演示说明,此账号不可用)
ip: 123.123.123.123
用户名:xx1
密码: xx2

2. ubuntu客户端界面配置

vpn-ubuntu

1. 点击右上角网络 –》VPN Connections –》Configure VPN
2. 新建一个VPN连接–》Add
3. 输入VPN账号:–》Advanced
Connection name: 连接号
Gateway: VPN服务器IP
Username: 用户名
Password: 密码
4. 高级选项 –》 Use Point-to-Point encryption(MPPE)
5. 选择VPN连接 –》 连接成功提示。

3. ubuntu命令行配置

安装pptp客户端软件

~ sudo apt-get install pptp-linux

查看网络配置

初始化一个VPN的连接通道:myvpn

~ sudo pptpsetup --create myvpn --server xxx.xxx.xxx.xxx --username xx1--password xx2--encrypt --startUsing interface ppp0Connect: ppp0  /dev/pts/1CHAP authentication succeededMPPE 128-bit stateless compression enabledlocal  IP address 10.10.10.3remote IP address 10.10.10.1

成功连接到远程VPN服务器。

通过刚才的创建脚步:
在/etc/ppp/peers目录下面,会生成一个叫myvpn的文件。
在/etc/ppp目录下面,用户名和密码会写在chap-secrets文件中。

~ sudo vi /etc/ppp/peers/myvpn# written by pptpsetuppty "pptp xxx.xxx.xxx.xxx --nolaunchpppd"locknoauthnobsdcompnodeflatename conan2remotename myvpnipparam myvpnrequire-mppe-128#生成用户名和密码~ sudo vi /etc/ppp/chap-secretsxx1 myvpn "xx2" *

通过网站路由功能,测试VPN

#安装traceroute ~ sudo apt-get install traceroute ~ traceroute www.163.comtraceroute to www.163.com (101.23.128.17), 30 hops max, 60 byte packets 1  localhost (192.168.1.1)  2.222 ms  3.144 ms  3.132 ms 2  111.192.144.1 (111.192.144.1)  80.279 ms  80.632 ms  80.624 ms 3  61.148.185.69 (61.148.185.69)  9.026 ms  9.492 ms  9.479 ms 4  124.65.61.157 (124.65.61.157)  9.469 ms  9.459 ms  9.447 ms 5  202.96.12.185 (202.96.12.185)  9.829 ms  9.783 ms  9.771 ms 6  219.158.96.110 (219.158.96.110)  17.160 ms  17.210 ms  17.158 ms 7  61.182.176.178 (61.182.176.178)  30.222 ms  28.589 ms  28.077 ms 8  60.5.194.58 (60.5.194.58)  29.293 ms  29.287 ms  29.276 ms 9  60.5.197.214 (60.5.197.214)  26.617 ms  26.724 ms  26.668 ms10  101.23.255.45 (101.23.255.45)  27.672 ms  28.147 ms  26.811 ms11  101.23.128.17 (101.23.128.17)  25.890 ms  28.065 ms  28.420 ms

我们发现虽然VPN已经连接成功,但是路由没有通过VPN上网,第1跳还是localhost (192.168.1.1)

再次查看网络连接配置

我们发现默认路由是指向eth0。
