Through the Httptunnel technology of this paper, while escaping the shield of firewall and the tracking test of the system, we can see that the network security depends only on some or some means is unreliable, while the blind dependence on the safety system often causes huge security hidden trouble. It is hoped that this paper can arouse the administrator's thinking on the netwo
