pptpd是在论坛上买的服务器里根据教程配置的。教程：http://wiki.ubuntu.org.cn/Vps#.E9.85.8D ... 。参数除了密码不一样，其它完全一致。
服务器那应该没什么问题，手机可以联上，以前ubuntu用图形界面配置VPN也可以联上。
客户端这边装的是 pptp-linux。
下面是我能想到的有关的信息，可能是哪配置不对？

# 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/
# and the kernel MPPE module available from the CVS repository also on
# http://ppp.samba.org/, which is packaged for DKMS as kernel_ppp_mppe.

# Authentication
# We don't need the tunnel server to authenticate itself

# We won't do PAP, EAP, CHAP, or MSCHAP, but we will accept MSCHAP-V2

# requires the use of MSCHAP-V2 during authentication)
