为了能够快速、高效地维护服务器的Linux 操作系统，降低维护门槛，实现定制化的远程登录。本文设计并实现一套基于Java 的Linux 远程登录系统，该系统不但能够自动登录服务器，还能根据不同的服务器进入不同的操作界面，操作界面上的功能按钮能够直接处理事项或维护系统。测试结果表明，与putty、SecureCRT等相比，该系统不但具备它们的所有功能，而且能够实现服务器操作定制化，使得处理事务和维护系统显得更加简单、方便、高效，它在很大程度上降低了维护服务器的难度，提高了服务器的管理水平。

For the enhancements of maintaining a Linux operating system with quick and high performance and realizing a customized remote login functionality, this paper proposes the design and implementation of a Java-based Linux remote login system.The system not merely enables automatic server login, but also provides different operating interfaces according to the servers. The functional buttons on the interface can be utilized to operate and maintain the system conveniently. The experimental results, compared with putty and SecureCRT, indicate that the proposed system covers all the functions and realizes customized server operations.It makes the system operations and maintenance more effortless, convenient and efficient. Accordingly, the system can significantly reduce the difficulty of server maintenance and also improve the level of server management.
