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.
