有人用pptp连接VPN成功吗？

黄色蚂蚁

我有一个VPN帐号，支持pptp，但好像不支持openvpn
我安装了pptpclient后，按照网上的教程配置好，但连接总不成功，高人看一下哪里出问题？

其中提示信息中的：

这一行有点问题
因为我的
ls /dev/pts

只有4个文件
ls /dev/pts -l

c--------- 1 root root   5, 2  9月  9 2010 ptmx

我的系统完全没有/dev/pts/3这个文件
不知这个文件是pptp创建的，还是pptp需要的？

请高人看一下我的哪里出问题了
谢谢

pptp从来就没成功过
希望成功的人士分享下经验

macrosun

问题在一开始就出现了：

anon warn[open_inetsockptp_callmgr.c:329]: connect: No route to host
anon fatal[callmgr_mainptp_callmgr.c:127]: Could not open control connection to 74.82.202.123

麻烦你先检查一下这个

luyaotang

我也是没成功过。。。关注。

哈哈哈哈,我一直是成功的
根据这个设置的,非常简单
http://pptpclient.sourceforge.net/howto-debian.phtml

黄色蚂蚁

楼上的发行版是archlinux吗？

我根据这个设置
http://pptpclient.sourceforge.net/howto-debian.phtml
出现的是同样的故障

并且上面的文档没有关于archlinux的

Havanna

我是使用这个http://aur.archlinux.org/packages.php?ID=13939
用的是vpn98
但从没成功过

用networkmanager成功连接过
装上networkmanager-pptp就行。

zlowly

安装pptpclient
用pptpsetup建立一个VPN TUNNEL（也可以自己在/etc/ppp/peers下手工创建配置文件），详细命令行参数用pptpsetup --help可以看到，应该很容易理解。

创建完TUNNEL以后，因为我用的是netcfg，所以直接修改/etc/netword.d里的连接配置文件，加上

POST_UP="pon 你的TUNNEL名"

用networkmanager的同学请自行摸索。
现在如果你顺利连网了以后，ppp就会自动建立了，用ifconfig会看到多了一个ppp0的连接。

光连通vpn其实还不够的，接下来应该还要做些网络配置，至少你得配一下网关，否则那个连接就是个摆设。例如我希望访问google dns的连接都通过ppp0出去，可以这样：

route add -net 8.8.0.0 netmask 255.255.0.0 dev ppp0

为了每次联通vpn都能自动配置网络，可以在/etc/ppp/ip-up.d里加上一个01-routes.sh，内容如：

#!/bin/sh
PATH=$PATH:sbin
route add -net 8.8.0.0 netmask 255.255.0.0 dev ppp0

当然你可以按自己需要来配置，甚至将网关配置为所有连接都走vpn都没问题。

官方wiki也有相关内容：

@ zlowly


怪异的是pon vpn不行，一定要pon 2 nodetach才行
这是何故？


PS:汗，原来是连接需要时间，我在没连上的时候ifconfig看了....
成功了.....

总结下
配置
sudo pptpsetup --create vpnname --server vpnserver --username name --password 123456 --encrypt
OK了，然后
pon vpnname
route add default dev ppp0(ppp0可能为其他....例如ppp1，ifconfig看下)
成功！
