匿名 (未验证) 提交于 2019-12-03 00:26:01
一、OpenStack官方配置文档: https://docs.openstack.org/neutron/latest/admin/vpnaas-scenario.html https://docs.openstack.org/neutron-vpnaas-dashboard/latest/install/index.html 二、新路历程: 安装VPNAAS的时候遇到了很多问题,现有的很少的安装配置文档都是基于老版本的,现在整理一个Q版本的VPNAAS环境部署方便大家配置自己的安装环境 少走我的弯路。 三、配置VPNAAS OpenStack版本: Q 开发环境: Ubuntu16.04 安装步骤: 1.apt-get安装 neutron-vpnaas apt-get -y install neutron-vpnaas 2.pip安装 neutron-vpnaas-dashboard 如果没有安装pip需要先安装 apt-get -y install python-pip 然后 pip install neutron-vpnaas-dashboard 3.到 openstak 的 dashboard 安装路径下新建文件 _7100_project_vpn_panel.py 当然你也可以选择下载 neutron-vpnaas-dashboard源码,找到这个文件放到对应目录下即可

网络层―虚拟专用网VPN

匿名 (未验证) 提交于 2019-12-03 00:22:01
我们都知道,像一些机构中,它的IP地址往往只有一个,但它的主机数却很多。那么这一个或者几个IP地址是如何分配给这么多台主机使用的。这就和虚拟专用网有关系了。 让多台计算机仅使用一个有效的IP地址,而不向互联网机构申请全球唯一的IP地址,这样就可以节省大量的IP地址资源了。但是我们如果任意选择一些IP地址作为本机内部使用的本机地址,在某些情况下,就可能会使本地地址与互连网中的地址重合,就会出现地址二义性问题。 为了解决这一问题,于是提出了指明一些专用地址,只能用于机构内部通信,而不能用在互联网上的主机通信。采用这样的专用IP地址的互连网就被成为专用网,也被成为可重用地址。因为专用互连网有很多相同的专用IP地址,但彼此并不会相互干扰,引起麻烦。 当专用网不同网点之间的通信必须经过公用的互联网,但又有保密的要求,那么所有通过互联网传送的数据都必须经过加密。 VPN的分类: 远程接入VPN:客户端到网关。在外驻留的员工电脑的VPN会和公司主机之间建立VPN隧道。 内联网VPN:网关到网关,通过公司的网络架构连接来自同公司的资源 外联网VPN:通常是与合作伙伴构成的,两个公司的资源进行连接。 VPN的实现: VPN服务器:在大型局域网中,可以通过在网络中心搭建VPN服务器的方法实现VPN 软件VPN:通过专用的软件实现 硬件VPN:通过专用的硬件实现 集成VPN:通过硬件设备,路由器

正常设置VPN配置后,连接报错。这时候就需要修改注册表信息咯。 1.,开始 -> 运行 -> regedit -> 确定 2,找到如下路径:HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Rasman\Parameters 3, 在“编辑”菜单上,单击“新建”->“DWORD值” 4.,在“名称”框中,键入“ProhibitIpSec” 5. 在“数值数据”框中,键入“1”,然后单击“确定” 6,找到 AllowL2TPWeakCrypto 键,将其值修改为 1 7,重启电脑就OK了。 转载请标明出处: Win10连接VPN L2TP报错解决办法 文章来源: Win10连接VPN L2TP报错解决办法

利用VNC实现Windows远程访问Linux服务器小结

孤者浪人 提交于 2019-12-02 21:36:49
环境 VMWare 7.1 + Redhat Linux9 + VNCViewer 小结 1. Linux 下安装VNCServer,由于我的机子上本来就有,在此不赘述。详情参考 此文 ; 2. 准备VNCViewer,点击此处 下载 ; 3. Linux下启动VNCServer,然后终端输入vncserver:2,为远程访问的会话设置密码(2为会话号,注意冒号前有空格,最开始我没设置会话号,见下图); [plain] view plain copy service vncserver start service vncserver stop service vncserver restart vncserver :2 4. 打开第二步下载的VNCViewer,输入IP,注意要把会话号带上,点击connect,就可以连接了; 5. 访问成功后还可以保存当前会话,下次只需要打开该文件即可访问了。如: 192.168.223.100-5902.vnc; 6. 这个跟Windows下的远程桌面连接很相似,呵呵。 7. 我们可以这样做:平时使用终端可以使用putty,需要涉及Linux下的图形界面可以使用本文介绍的vncviewer,本机多个用户访问可以使用SSH。 资源下载 本文提到的3个小工具下载地址(无偿分享,欢迎下载 ): vncviewer.exe putty.exe

How are existing VPN applications creating new profiles in Android 2.0 - 2.3?

你。 提交于 2019-12-02 19:05:10
After much searching on StackOverflow, it seems rooting a device in the only way to create a VPN profile pre-4.0 My question is how do the following apps do it without root? http://www.featvpn.com/ https://play.google.com/store/apps/details?id=com.expressvpn.vpn&hl=en Update 1 Seems private API is the way to go pre-4.0. Unfortunately, not many resources out there to get started. Does anyone know if private api still requires a rooted device? Update 2 It seems you can do this using modified Android.jar or by using reflection. L2TP/IPSEC still requires rooted device. PPTP does not seem to. How

NetworkExtension connectOnDemand rules doesn't work

不想你离开。 提交于 2019-12-02 15:21:52
问题 I have an app with VPN config created by the new NetworkExtension framework. It works just fine, but now I need to add some rules to turn this VPN only when I'm trying to connect to a specific URL. I planed to use NEVPNManager's connectOnDemand feature, but it does`t seem to be working for me. When I'm opening http://some-site.com in safari my VPN connection should establish, but for some reason it does't. I tried a different type of configurations as well as using generated .mobileconfig

iOS app with custom VPN connect

血红的双手。 提交于 2019-12-02 03:22:29
问题 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. 回答1: 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

How do I get the current logged in Active Directory username from VBA?

北城以北 提交于 2019-12-02 03:04:51
问题 I am new to Active Directory. I have a VBA Excel Add-In that should run if, and only if, the computer that it is running on is currently logged into the Active Directory, whether locally or through a VPN. Knowing the domain name, how would I retrieve the user name for the currently logged in user? Thanks! 回答1: EDITED: If I understand your situation properly, then you might be going about this the wrong way. When your app starts up, you could do a simple ping against a machine that the user
