pptp

I am creating my own AOSP that contains my own apps and services. One of those services creates ppp0 interface and tries to link specific apps to be forwarded through that interface. I have tried these commands but it was not working as expected. iptables -t mangle -A OUTPUT -m owner --uid-owner 10088 -j MARK --set-mark 100 ip route add via 10.0.0.201 dev ppp0 table 100 ip rule add from all fwmark 100 table 100 iptables -t nat -A POSTROUTING -m owner --uid-owner 10088 -j SNAT --to-source 10.0.0.201 ip route add default dev wlan0 By the way, 10.0.0.201 is ppp0 interface Ip address. This works

I have setup a PPTP server on my own server. I follow this tutorial https://www.digitalocean.com/community/articles/how-to-setup-your-own-vpn-with-pptp But when I try to use my mobile phone or my PC to connect my PPTP server, it says PPTP server hang up,username or password is wrong. But I checked my username and password, they are ok. In my PPTP server log, something like this: Dec 14 03:57:46 localhost pptpd[2071]: CTRL: Client 121.32.107.56 control connection started Dec 14 03:57:46 localhost pptpd[2071]: CTRL: Starting call (launching pppd, opening GRE) Dec 14 03:57:46 localhost pppd[2072]

首先，推荐跑下面的脚本： https://github.com/BoizZ/PPTP-L2TP-IPSec-VPN-auto-installation-script-for-CentOS-7 这个脚本将pptp l2tp ipsec都按照，并且配置好，当然很多配置不准确 跑脚本的时候配置好ip规划，PPsk共享秘钥（这个后面客户端连接需要用到） 用户名 ，密码 （后面连接都需要用到） PSK共享秘钥在/etc/ipsec.secrets可以找到和配置 用户名密码在/etc/ppp/chap-secrets 可以找到配置 下面的简单修改流程： vim /etc/ipsec.conf config setup # NAT-TRAVERSAL support, see README.NAT-Traversal #nat_traversal=yes # exclude networks used on server side by adding %v4:!a.b.c.0/24 virtual_private =% v4 : 10.0 . 0.0 / 8 ,% v4 : 192.168 . 0.0 / 16 ,% v4 : 172.16 . 0.0 / 12 # OE is now off by default. Uncomment and change to on, to enable.

1.购买PPTP账号，eg：飞速云 2.选择新的连接或网络 3.选择连接到工作区 Internet 地址填写你购买账号的服务器名称或IP 目标名称随便都可以 点击属性，修改模式参数 点击安全具体如图设置即可， 这边特别提醒哦：1.×××类型选择 点对点隧道协议PPTP 2.数据加密选择 可选加密（没有加密也可以连接）

i want to create app which can connect to VPN using PPTP, L2TP or OpenVPN, but i cant find any information about this. Only found infortmation about using IPSec and IKEv2 in ios 8 SDK. If you want to connect programatically in ios 8 you can use only IPSec or IKEv2 protocols. L2TP and PPTP protocols are private for apple. It is not possible to use L2TP and PPTP APIs in your applications. Only Apple is currently using these APIs. 来源： https://stackoverflow.com/questions/26257872/ios-app-with-custom-vpn-connect

1.检查是否支持pptp 返回ok即表示支持 modprobe ppp-compress-18 && echo ok 2.安装ppp yum install -y ppp 3.安装pptpd 首先要安装epel源，由于官方源已经移除pptpd包，需要安装第三方源epel yum install -y epel-releaseyum install -y pptpd 4.修改 /etc/pptpd.conf 文件 配置本地隧道网卡地址，及客户端地址池，需要同一网段 localip 10.10.10.1 remoteip 10.10.10.10-100 5.修改 /etc/ppp/options.pptpd 文件 配置隧道dns ms-dns 8.8.8.8 ms-dns 8.8.4.4 6.修改 /etc/ppp/chap-secrets 文件 添加pptp vpn账号与密码，格式：用户名 pptpd 密码 ip地址 test pptpd 123456 * 7.修改 /etc/sysctl.conf 文件 允许系统路由转发，修文件后执行命令 sysctl -p 立即生效 net.ipv4.ip_forward=1 8.创建并编辑 /usr/lib/firewalld/services/pptpd.xml 文件 定义防火墙服务pptpd，创建编辑完后执行命令 firewall-cmd
