At first, my vps was installed with Ubuntu10.10. In this version, I had been tossing for several days and failed to succeed. Later, after I upgraded the system online, I installed and configured openvpn. Finally, yes. If a new system version is available, a prompt will be displayed when the user just logs in. For example, enter ldquo; do-release-upgrade rdquo in shell directly; you can upgrade to the next version. I am a linux cainiao, so I will mak

You need to turn on SSH to connect your cloud server as root or user using sudo to access SSH connections. This guide assumes that users use sudo access. But you can take things using roots only by stripping "sudo" from the start of each command. If you are running Linux or Mac on your system, you can use the SSH terminal program. If you are using Windows, you can use putty to login to SSH. Once the terminal is open, assuming you are using the LINUX/MAC system, you can login to enter the followi

Generally, Linux servers that provide Web Services seldom need to connect to OpenVPN, but personal Linux computers often need to connect to OpenVPN. For example, if you use Linux as the development environment, you need to connect to the company's OpenVPN. This document uses Ubuntu as an example to describe how to connect to the remote

The difference between an OpenVPN internal route and a system route is that the system route completely follows the longest prefix matching principle. After finding the route, the data packet is forwarded from the corresponding Nic interface. Although the routes inside OpenVPN ultimately decide whether to forward and where to forward data packets, this "whether to forward" and "where to forward" is very dif

First, the working principle of OpenVPN VPN technology establishes a private tunnel on the public network through key exchange, encapsulation, authentication and encryption, which guarantees the integrity, privacy and effectiveness of the transmitted data.

OpenVPN is the first choice for VPN servers. There are two solutions for how openVPN breaks through the firewall blocking. One is to use the http-proxy that comes with openVPN, second, use HttpTunnel 1. the http-proxy provided by liopenvpn breaks through the firewall blockingOpenVPN itself can use an http proxy.
