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

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
