# Sample Poptop PPP options file /etc/ppp/pptpd-options
# Options used by PPP when a connection arrives from a client.
# This file is pointed to by /etc/pptpd.conf option keyword.
# 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 and the kernel MPPE module.

# Authentication
# (must match the second field in /etc/ppp/chap-secrets entries)
name gw3121
# Optional: domain name to use for authentication
# domain mydomain.net
# Strip the domain prefix from the username before authentication.
# (applies if you use pppd with chapms-strip-domain patch)
#chapms-strip-domain

# Encryption
# Debian: on systems with a kernel built with the package
# kernel-patch-mppe >= 2.4.2 and using ppp >= 2.4.2, ...
# {{{
#refuse-pap
#refuse-chap
#refuse-mschap
require-chap
require-mschap
# Require the peer to authenticate itself using MS-CHAPv2 [Microsoft
# Challenge Handshake Authentication Protocol, Version 2] authentication.
require-mschap-v2
# Require MPPE 128-bit encryption
# (note that MPPE requires the use of MSCHAP-V2 during authentication)
#require-mppe-128
# }}}
 

# Network and Routing
# If pppd is acting as a server for Microsoft Windows clients, this
# option allows pppd to supply one or two DNS (Domain Name Server)
# addresses to the clients.  The first instance of this option
# specifies the primary DNS address; the second instance (if given)
# specifies the secondary DNS address.
ms-dns 166.111.8.28
ms-dns 166.111.8.29
# If pppd is acting as a server for Microsoft Windows or "Samba"
# clients, this option allows pppd to supply one or two WINS (Windows
# Internet Name Services) server addresses to the clients.  The first
# instance of this option specifies the primary WINS address; the
# second instance (if given) specifies the secondary WINS address.
#ms-wins 10.0.0.3
#ms-wins 10.0.0.4
# Add an entry to this system's ARP [Address Resolution Protocol]
# table with the IP address of the peer and the Ethernet address of this
# system.  This will have the effect of making the peer appear to other
# systems to be on the local ethernet.
# (you do not need this if your PPTP server is responsible for routing
# packets to the clients -- James Cameron)
proxyarp
# Debian: do not replace the default route
nodefaultroute

# Logging
# Enable connection debugging facilities.
# (see your syslog configuration for where pppd sends to)
debug
# Print out all the option values which have been set.
# (often requested by mailing list to verify options)
#dump

# Miscellaneous
# Create a UUCP-style. lock file for the pseudo-tty to ensure exclusive
# access.
lock
# Disable BSD-Compress compression

建立连接

control pannel -> Network Connections -> create a new  connect ->   next -> connect to the network at my working place -> next ->   virtual private network connection -> campany name (input: 3-121) ->   Host name or IP address (input: 166.111.202.141) -> finish

设置连接

duble click the connection created just now -> properties -> security ->   advanced(custom setting) ->optional encryption( connect even no encryption) ->   allow this protocal -> CHAP (only choose this) -> OK -> Yes

 配置无果，看到以下消息，崩溃了

注意：来自@LEMONed的消息，只有Xen的VPS可以搭建pptp，OpenVZ的不行。

引用来自@LEMONed的话：
因为openvz下只有venet0，没有eth0，而绝大多数的vps都是openvz的，然后绝大多数的openvz vps都没有masqurade，只能搭建openvpn并且要自签证书什么的，根本不能用pptpd。我为了给iphone搭个vpn曾经把这个研究透彻了
