I. INTRODUCTION to OpenVPN is a software package used to create a VPC encrypted channel. it was first written by JamesYonan. OpenVPN allows the created VPN to use a public key, digital certificate, or user name/password for authentication. It uses a large number of SSLv3/TLSv1 protocol libraries in the OpenSSL encryption library. Currently, OpenVPN can be used in

1. OpenVPN relies on a virtual TUNTAP device to implement SSLVPN. Therefore, the kernel must support the TUNTAP device module. This configuration option is located in the 2.6.x kernel and is in the DeviceDrivers-Networkdevicesupport menu. It is called UniversalTUNTAPdevicedriversupport, in the standard kernel 1. OpenVPN implements ssl vpn Based on Virtual TUN/TAP devices. Therefore, the kernel must support

Create a wireless route for Raspberry Pi OpenVPN is a private protocol and requires proprietary clients. Therefore, it is difficult to use OpenVPN on Android (CM9 supports OpenVPN), iOS, and WP8. Combining Raspberry Pi and OpenVPN to build a soft AP can easily solve these problems. Why is this combination selected? Ra

If you add a service account that contains a special character @ or \, the vcenter Server installation will failWhen you install Vcenter Server, you can specify a service account instead of using the default Windows Local System account. If the selected account name contains a special character @ or \, the installation may fail and generate the VPXD first boot error. Workaround: When installing vcenter Server, create a service account that does not contain a spec

router. When the indicator of the router starts to flash fast, it indicates that the security mode has been entered.3. The security mode does not load any configurations. Therefore, you need to connect directly and connect to the vrotelnet through telnet 192.168.1.1.4. Mount the root partition: mount_root5. Erase the previous configuration: firstboot6. Set Password: passwd root7. Restart: reboot-f Then you can re-start the configuration. If an error occurs when the configuration is erased throu

Safe mode does not load any configuration, so you also need to connect the router via Telnet 192.168.1.1 via the first mentioned method4, Mount root partition: Mount_root5, Erase the previous configuration: Firstboot6. Set Password: passwd root7, restart: reboot-f You can then restart the configuration, if the process through the Firstboot erase configuration encountered errors, can be openwrt in the way to brush the machine to solve.

Install an open-source VPN Server on CentOS 7 One of my biggest concerns when I access the Internet is how to ensure the security and privacy of my data. While searching for answers, I found many anonymous methods, such as using a proxy website. However, third-party services cannot be fully guaranteed. What I need is a software that allows me to install and run on my own, so that I can ensure that only I can access data. What is this software called? It is called VPN service, short for virtual

application, such as OpenVPN, is a good open-source software. Our products provide PPTP and OpenVPN applications. PPTP is mainly used by users who often go out for mobile or home office work; openVPN is mainly used for non-stop on-demand VPN connections between companies in different regions, such as ERP applications in enterprises.OpenVPN allows you to use the

The adapter mode is to convert an interface of a class to another interface that the customer wants, so that those classes that cannot work together due to incompatibility of the interface can work together. I don't know if you have used the adapter mode in daily coding, but the working mode of the adapter is very common in our life. This article uses the oldest but most representative example to explain. Now there is an electrical appliance worth 1
