木馬技術是網絡安全的重要方面，也是網絡攻防中獲取信息的重要途徑。從本質上
講，木馬就是一個網絡服務程序，由客戶端進行控制，來執行某些特定的命令。但是由于其應用場合的特殊性，使得木馬的設計實現在很多方面有別于普通的服務程序，其中最主要的是隱藏技術、控制手段和信息獲取等三方面，本文將從這些方面著重討論Linux 環境下的木馬技術。

Abstract:Trojan horse technology is an important part in the research of network security, and it is also an important way to get the important information from the network. The Trojan horse is essentially a network program that works as a server in the hacked host computer, and can be controlled by the client to execute some command in the host. But because the working environment is special, the Trojan horse has much more difference from other ordinary network program and must be designed specially. It mainly include that the Trojan should consider the way of hiding, controled way and information gotten. This paper will discusse the Trojan horse technology in the Linux environment from three aspects.
