您可以使用以下步骤从终端配置 pptp VPN 服务器和客户端：

VPN 服务器设置：

安装并更新VPN服务器和客户端包：

$ sudo apt-get install pptpd ppp pptp-linux

必须为服务器配置四个文件：

  • /etc/pptpd.conf
  • /etc/ppp/pptpd 选项
  • /etc/ppp/选项
  • /etc/聊天秘密）

/etc/pptpd.conf：

选项 /etc/ppp/pptpd-options
日志记录
本地IP 192.168.23.20
远程IP 192.168.23.30-39

/etc/ppp/pptpd-选项：

名称 pptpd
拒绝
拒绝
拒绝mschap
需要 mschap-v​​2
需要-mppe-128
代理ARP
无默认路由
锁
诺布斯德科姆
noipx ## 你不需要 IPX
mtu 1490 ## 可能有助于您的 Linux 客户端断开连接
mru 1490 ## 可能有助于您的 Linux 客户端断开连接

/etc/ppp/选项：

lock

/etc/ppp/chap-secrets：

# 使用 CHAP 进行身份验证的秘密
# 客户端服务器秘密 IP 地址

[用户名] pptpd [用户密码] *

（[用户名] 和 [用户密码] 是不带括号的条目。）

现在使用以下命令重新启动服务器：

$ sudo service pptpd restart

VPN 客户端设置：

涉及四个配置文件：

  • /etc/ppp/peers/myvpn
  • /etc/ppp/options.pptp
  • /etc/ppp/chap-秘密
  • /etc/ppp/ip-up.local

在 /etc/ppp/peers/myvpn 中：

# 将括号参数替换为 VPN 服务器和 VPN 用户的主机名
远程名称 myvpn
链接名称 myvpn
ipparam myvpn
pty“pptp [vpn 服务器] --nolaunchpppd”
name [用户名]
使用peerdns
需要-mppe
拒绝 EAP
沒有授權

# 采用 pptp-linux 包中的默认值
文件 /etc/ppp/options.pptp

/etc/ppp/options.pptp：

锁
沒有授權
拒绝
拒绝 EAP
拒绝
拒绝mschap
诺布斯德科姆
节点放气

/etc/ppp/chap-secrets：

# 使用 CHAP 进行身份验证的秘密
# 客户端服务器秘密 IP 地址
用户名 myvpn 密码 *

/etc/ppp/ip-up.local：

/bin/sh #!/bin/sh 复制代码
网络 =`echo $IPREMOTE | awk -F\。'{print $1"."$2"."$3".0/24"}'`
路线添加-net $ network $ IFNAME

将 VPN 客户端连接到：

$ sudo pon myvpn

使用以下命令结束 VPN 连接：

$ sudo poff myvpn

修改自@LDJames 解决方案

Ubuntu 16.04

VPN 客户端设置：

涉及四个配置文件：

  • /etc/ppp/peers/myvpn
  • /etc/ppp/options.pptp
  • /etc/ppp/chap-秘密
  • /etc/ppp/ip-up.local

在 /etc/ppp/peers/myvpn 中：

# 将括号参数替换为 VPN 服务器和 VPN 用户的主机名
远程名称 myvpn
链接名称 myvpn
ipparam myvpn
pty “pptp 1.2.3.4 --nolaunchpppd --loglevel 0”
锁
节点放气
名称 登录名
使用peerdns
需要-mppe
沒有授權
需要-mppe-128
  1. 改变1.2.3.4到您的 VPN 主机 IP 地址。和
  2. 改变登录名到您的登录名

/etc/ppp/options.pptp：

锁
沒有授權
拒绝
拒绝 EAP
拒绝
拒绝mschap
诺布斯德科姆
节点放气
名称 登录名
需要-mppe-128
ipparam myvpn
  1. 改变登录名到您的登录名

/etc/ppp/chap-secrets：

# 使用 CHAP 进行身份验证的秘密
# 客户端服务器秘密 IP 地址
登录名 myvpn 登录密码 *
  1. 改变登录名到您的登录名
  2. 改变登录密码您的登录密码

/etc/ppp/ip-up.local：

/bin/sh #!/bin/sh 复制代码
网络 =`echo $IPREMOTE | awk -F\。'{print $1"."$2"."$3".0/24"}'`
路线添加-net $ network $ IFNAME

使用以下命令启动 VPN 客户端：

$ sudo pon vicomvpn dump logfd 2 nodetach
pppd options in effect:
nodetach        # (from command line)
logfd 2     # (from command line)
linkname myvpn      # (from /etc/ppp/peers/myvpn)

remotename myvpn        # (from /etc/ppp/peers/myvpn)
        # (from /etc/ppp/peers/myvpn)
pty pptp 1.2.3.4 --nolaunchpppd --loglevel 0        # (from /etc/ppp/peers/myvpn)

usepeerdns      # (from /etc/ppp/peers/myvpn)
nodeflate       # (from /etc/ppp/peers/myvpn)
require-mppe        # (from /etc/ppp/peers/myvpn)
require-mppe-128        # (from /etc/ppp/peers/myvpn)
noipx       # (from /etc/ppp/options)
Using interface ppp0
Connect: ppp0 <--> /dev/pts/22
CHAP authentication succeeded
MPPE 128-bit stateless compression enabled
local  IP address 192.168.1.142
remote IP address 192.168.1.1
primary   DNS address 19.168.1.1

使用以下命令结束 VPN 连接：

$ sudo poff myvpn

参考 ：MS-CHAP[v2] 身份验证，使用 pptpclient 设置 Microsoft VPN 客户端
