Ubuntu 配置PPTP客户端

本文介绍一下命令配置PPTP客户端的过程。

 

A.安装pptp客户端软件　

sudo apt-get install pptp-linux

 

B.查看网络配置

C.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 --start

Using interface ppp0
Connect: ppp0 <--> /dev/pts/3
CHAP authentication succeeded
MPPE 128-bit stateless compression enabled
local  IP address 172.31.26.100
remote IP address 172.31.26.143

　　

 

成功连接到远程VPN服务器

D.1.断开VPN连接

poff myvpn

　　

 2.重新连接VPN

pon myvpn

　　

 3.读取配置文件重新连接VPN

sudo pppd call myvpn  updetach

 

4.处理错误

LCP: timeout sending Config-Requests

处理方案：sudo modprobe nf_conntrack_pptp
