Recently coincided with Cyber ??Security Awareness Week, as undergraduate computer science students of course have to respond to the call of the CPC Central Committee. This article describes the first use of some of the things Torjan.

Foreword

I recently felt the pinch on Twitter, saying ladder down a batch after batch, but I own three servers are very good, showing that you do not get money out of him, and no one make trouble for you. This thing over the wall itself or technology live, even if it is a technical threshold screening. Generally own operation and maintenance of a Linux build a ladder, often qualities are not too bad (that is, "can see", such people usually are generally higher ability to search and organize information); but is able to turn money kind, leading to a large number of Han did not know spade believe what people go outside the network unpleasant to go. So this is not taught how you use Trojan over the wall, in fact, I also do not intend to use him as the main. This article only describes the process only memo.

Installation

Torjan installation very easy, there is a line commands like copy and paste on Github. After the simple installation instructions in the documentation modify the configuration file can be run, and the only two not very good at that one client can not quite complete, but at present a better experience on your computer, Android client is still in development, I heard not very stable, there is no try. But I think it was just all of a sudden what clients are particularly popular, unless the proxy itself strong technology, otherwise it far from dead.

The actual test run, I am currently the main ladder is V2Ray to compare, test way is to look at youtube 4K video. V2Ray can reach 50000 + kbps, and Trojan can reach 80000 + kbps, was quite beyond my expectation.

Remark

Trojan's principle is to imitate Https traffic, and imitation is very real. So you want to transfer agents must be allowed to flow requires Trojan to deal with TLS, and like V2Ray + WS with Nginx reverse proxy do not work, but in turn can allow the Trojan Trojan treatment TLS, if it is an ordinary Https request forwarded to Nginx server, where the data is forwarded by ordinary HTTP requests.

In fact, the whole experience is quite good, installation configuration of many aspects than V2Ray simple. I consider it as a spare ladder for a rainy day. At first I discounted the three-year NordVPN want as a backup means, the results of the National Day to tell me their whole server to hang up, I think they should refund my money.
