Configure point-to-point VPN on CentOS
A Traditional VPN (such as OpenVPN and PPTP) is composed of a VPN Server and one or more clients connected to this server. When any two VPN clients communicate with each other, the VPN Server needs to relay the VPN data traffic between them. The problem with such a central radiation VPN topology is that when the number of connected clients increases, the VPN Server can easily become a performance bottleneck. In a
Kali linux 2.0 implements scientific Internet access through host machine proxy
One of the biggest problems with using kali linux is that it cannot smoothly download and update resources from the official resource library.
Now in China, the solution is to first find other unofficial update sources, then download the updates, and then install openvpn (2.0 has been installed by default), and then scientifically access the internet. However, the update s

Recursive control facilitates the arbitrary superposition of control logic, which we have seen in the design of the protocol stack, such as X over Y, XoY for short, such as PPPoE, IP over UDP (OpenV

In the RedHat Fedora Project, there is an epel (extra packages for Enterprise Linux), which is the RHEL fedora software repository. By adding it, you can get a lot of free software packages that support RHEL/centos. For example, nginx and openvpn, which are currently popular, can be easily installed and updated.

Overview
N2n is an open-source p2p VPN software. its author is Luca deri, a famous open-source network management software ntop.
N2n is a dual-layer VPN, which allows users to develop typical P2P application functions at the network layer, rather than at the application layer. This means that users can obtain the same visibility as local IP addresses (for example, two PCs in the same n2n network can ping each other) and access each other through IP addresses in the n2n virtual network, you do
numerous application protocols, rather than relying on the outside. The same is true for both IPSec VPN (including OpenVPN) and SSLVPN. The SSL protocol only establishes an encryption channel, and the data is encapsulated by the record protocol. It does not have the ability to perceive videos. Compared with the IP layer encryption technology, the SSL protocol only improves the layer, maintains a state machine that is not suitable for video encryption
understandable book about TCP details. Look at the specifications, various formulas, various non-pluggable algorithms, and various magic words, even though the author's estimation is hard to tell the details inside. I have to say that TCP is a little over-designed. As the design product of the year, it is not suitable for the more advanced layer migration era. Nowadays, more and more protocols or open-source software are using simple UDP for expansion. In order to achieve sequential arrival, co
Summarize the virtual network of vmware workstation, and then compare the similarities and differences between the two:
1) There are three network types: Bridge, NAT, and Host-only;
2) The Bridge type can only Bridge one network card at a time. That is to say, there are several network cards on your computer (Logical Network Card, such as openvpn) that can only be built with several Bridge networks, of course, the total number cannot exceed 10;
