We're currently developing a Windows Smartclient that needs to authenticate users using their AD group membership. We now have a requirement for some users to connect over VPN. Is there any way I can get the AD account identity and groups from the VPN login? WindowsIdentity.GetCurrent() returns the local user account rather than their VPN account information. The local account name is different that the AD account used for the VPN connection. i.e the user is on their home PC, and connecting to the office using their work AD account.

linux下的ping 和windows下的ping稍有区别,linux下ping不会自动终止, 需要按ctrl+c 终止或者用参数-c指定要求完成的回应次数。 class A{} ; class B : public A {}; ubuntu手动 配置pptp建立vpn 。　　　 http://blog.fens.me/ubuntu-vpn-pptp/ 建立vpn后，在win8的vpn连接》属性》网络》ipv4》属性》高级》IP设置》在远程网络上使用默认网关。若勾上后连接上VPN，则能翻墙，若不勾上，不能翻墙。 原因不理解。 勾上则加了一条默认路由，全部从VPN走！ iptables 图文解析 。　　 http://blog.csdn.net/yu_xiang/article/details/9212543 iptables 命令文档说明。　　 http://blog.chinaunix.net/uid-26495963-id-3279216.html 将墙内网与墙外网分开分别走电信和VPN（操作失败。。。），主要不理解第二大步的3（查看VPN网关地址）,4（添加路由）小步。　　 http://wangyan.org/blog/custom-vpn-route.html 来源： http://www.cnblogs.com/3chimenea/p/4122353.html

I would like to block all connections to my server that use a VPN or Proxy. Is there anyway to detect that a VPN or proxy connection is being used? If not, is there anyway that I can check the likelihood that a VPN or proxy is being used? Lastly, is there anything that I can query or prompt the user with to check if they are using a VPN or Proxy so that if anyone does get through, I can try and perform additional verification? I do not need any information from the user such as location, true IP, or anything like that. I just want to entirely bar connections from VPNs or Proxies. Edit: I've

Since the release of iOS 8 beta, I found a Network Extension framework in its bundle which is going to let developers configure and connect to VPN servers programmatically and without any profile installation. The framework contains a major class called NEVPNManager. This class also has 3 main methods that let me save, load or remove VPN preferences. I’ve written a piece of code in viewDidLoad method as following: NEVPNManager *manager = [NEVPNManager sharedManager]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(vpnConnectionStatusChanged) name

I need to implement an Android app that would allow the user to configure a VPN connection without having to access the native menu of the Android device. With this I have two problems: in Android 4.0 + (api level 14 and above) I have found there is a new component called VpnService which provides a hook for creating a virtual network interface, configuring it and intercepting / forwarding pachets from it to a VPN server, but there are no built in vpn protocols like PPTP or IPSec, there is just the possibility of implementing them. My question is is there any ready made solution for PPTP and

其实这个百度百科也并没有给出明确的定义，我个人理解为将多台没有公网IP的服务器，依赖于一台有公网IP的服务器来组成局域网络（非frp或者是说蒲公英那种单端口映射或收费的方式）目前想寻找开源化异地组网项目。 为什么想搞异地组网： 现在正在学习云计算需要用到openstack 和 k8s等，自己想把自己租的屋子里面的电脑弄成基于单节点CentOS下部署的openstack，在openstack下搭建k8s集群在K8s集群上搭建CICD和安全审计平台，所以项目架构比较大，每天快到11点才到家进度很慢，所以想将服务器映射出来，但是奈何资金紧张不可能办理固定IP，所以才想到弄成异地组网，自己有一台云服务器，是否能够通过vpn的形式让家里的电脑和自己的笔记本加入到一个网络中组成一个局域网呢？（灵感来源于上一家企业用到的深信服的VPN技术）。在尝试过openvpn的部署后确实能连接上去了，但是无法进行内网通讯这就尴尬了，关键是还不报错，这是世界上最难解决的问题了，百度也帮不了你。所以想来想去决定放手一搏通宵研究一下这个异地组网，目前一共找到了两个解决方案,今天就介绍第一款。 PacketiX VPN 这个工具配置简单效率高简单。 使用wget下载下来 wget https://github.com/SoftEtherVPN/SoftEtherVPN_Stable/releases

I'd like to know whether it's possible to create a VPN interface programmatically with the new VPN APIs in Android 4.0. I've looked through http://developer.android.com/resources/samples/ToyVpn but this is about creating a complete VPN client that handles the connections etc. I only want to add a new VPN configuration and possibly remove existing ones. There are lots of questions like this but they all seem to be pre 4.0. I understand that previously this wasn't possible, but one would think that the new VPN APIs provided such functionality. So has anyone found a way to do this, or is it still

0x00 前言 该事情发生于去年8月，当时我们开始了一个新的SSL VPN研究项目。与ipsec和pptp等站点到站点VPN相比，ssl vpn更易于使用，并且可与任何网络环境兼容。为了方便起见，ssl vpn成为企业最流行的远程访问方式！ 但是，如果这个可信的设备是不安全的呢？它是一项公司的重要资产，但却是公司的盲点。根据我们对财富500强的调查，排名前三的SSL VPN供应商占据了大约75%的市场份额。ssl-vpn的多样性很小。因此，一旦我们发现领先的ssl-vpn存在严重漏洞，其影响将是巨大的。没有办法降低损失，因为SSL VPN必须暴露在互联网上。 在我们的研究开始时，我们对领先的SSL VPN供应商的CVE数量进行了一些调查： 看起来Fortinet和Pulse Secure的VPN是最安全的。是真的吗？作为一个打破记录的破坏者，我们接受了这一挑战，并开始攻击Fortinet和Pulse Secure！这个故事是关于黑客攻击Fortigate SSL VPN。 0x01 漏洞影响 FortiOS 5.6.3 to 5.6.7 FortiOS 6.0.0 to 6.0.4 ONLY if the SSL VPN service (web-mode or tunnel-mode) is enabled. 0x02 Fortigate SSL VPN
