openvpn p2p

Abstract: P2P (Peer-to-Peer) communication has developed rapidly and has a great impact. Like traditional communication, P2P communication is also restricted by the NAT/FW traversal problem. Therefore, it is very important to solve the NAT/FW traversal problem. Compared with traditional communication, NAT/FW traversal in P2P communication has many unique issues a

(1) Common P2P protocols 1. Napster: the world's first large-scale P2P application network; centralized and collapsed. Napster, a popular sharing service at the time, is mainly used to find MP3 files. It has a server used to store the link location of MP3 files and provide retrieval, while the real MP3 files are stored in On thousands of PCs, files searched for are directly shared among PCs through

A few weeks ago, Canonical released the Ubuntu 14.04 LTS version. The new operating system has undergone great changes, but some problems still need to be solved, such as the openVPN import function. If you have used a VPN connection on Ubuntu, you should know that you have to download the network-manager-openvpn package from the official software package management center to achieve the VPN connection, it

The evolution of computer networks is swinging between centralization and distribution. In the early days, many users shared large computers, and personal computers were developed from centralized to distributed. Similar situations exist on the Internet. The client (browser)-server method is adopted to use the server in the website collection. Further development will be distributed, and centralized servers will become distributed. Each user terminal is both a client and a server. This is the pe

The impact of the HeartBleed vulnerability on Heartbleed continues to expand. People thought last week that HeartBleed was only a nightmare for web servers, but over time, the threat of Heartbleed to enterprise intranet and data security is truly exposed, resulting in greater losses than web Services, and the repair is more difficult and long. According to Ars, researchers have recently completed the verification attack and successfully extracted the encrypted private key from the VPN Service R

OpenVPN multi-processing-why notOpenVPN does not handle much. It is well known. I think it is a bit cool to say this every day. Why didn't I handle it more? Let's take a look at how James Yonan (JY for short), author of OpenVPN, has already exceeded code.OpenVPN 2.0 has no multithreading support, this is the only feature present inWell, it clearly shows that the OpenVPN
