centos pptp客户端 连接服务端

centos 7 命令行下可使用pptpsetup进行pptp拨号，首先安装ppp，pptp和pptp-setup三个包，使用pptpsetup进行连接。

1. 安装ppp，pptp，pptp-setup

# yum install ppp pptp pptp-setup -y

2. 使用pptpsetup进行连接

pptpsetup --createVPN名字 --server VPNip --username username --password password --encrypt --start
# pptpsetup --create  --server xxxx --username xxxx --password xxxx --encrypt --start
Connect: ppp0 <--> /dev/pts/1
CHAP authentication succeeded
MPPE 128-bit stateless compression enabled
local  IP address 192.168.160.13
remote IP address 192.168.160.10

3. 查看是否创建成功

使用ifconfig命令，可以看到会多了一个ppp0网口

# ifconfig 
ppp0: flags=4305  mtu 1396
        inet 192.168.160.13  netmask 255.255.255.255  destination 192.168.160.10
        ppp  txqueuelen 3  (Point-to-Point Protocol)
        RX packets 18  bytes 792 (792.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 9  bytes 90 (90.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

4. 添加默认路由

# route add default dev ppp0

5. 测试是否连上服务端

# ping xx.xx.xx.xx

6. 断开连接

# pkill pptp

7. 遇到的问题

# pptpsetup --create  --server xxxx --username xxxx --password xxxx --encrypt --start
Using interface ppp0
Connect: ppp0 <--> /dev/pts/1
EAP: unknown authentication type 26; Naking
EAP: peer reports authentication failure
Connection terminated.

解决方法：

# vim /etc/ppp/options
refuse-pap
refuse-eap
refuse-chap
refuse-mschap
require-mppe
