我已经使用ubuntu's guide 创建了PPTP VPN服务器。
现在我有:
我现在的问题是我的Android手机无法连接到我创建的pptp。当我尝试输入用户名和密码然后单击connect时,我仅有的消息是连接中... ,但之后是不成功的。
因此,我搜索并找到了link,以获取有关如何连接到我的PPTP VPN的一般概述。我也来了here,但仍然无法将手机连接到VPN。我完全遵循ubuntu's guide所说的,而且我现在不知道该怎么做才能实现我的目标。请提供一些链接或指南,以便我的Android手机能够连接到我的PPTP VPN。

# Sample PPTP PPP options file /etc/ppp/options.pptp
# Options used by PPP when a connection is made by a PPTP client.
# This file can be referred to by an /etc/ppp/peers file for the tunnel.
# Changes are effective on the next connection. See "man pppd".
#
# You are expected to change this file to suit your system. As
# packaged, it requires PPP 2.4.2 or later from http://ppp.samba.org/

最佳答案
谢谢大家,但是我通过检查 pptpd-options 文件并进行更改来解决此问题#require-mschap-v2
到require-mschap-v2
#require-mppe-128
到require-mppe-128
我也进行了更改,像这样删除#
refuse-pap
refuse-chap
refuse-mschap
newpeople
更新:并确保删除
noauth
选项。在他的情况下,由于它在require-mppe-128
和require-mschap-v2
之前,因此无效,但是如果仍然无法实现,请检查noauth
并将其删除。
