Method for realizing telnet of shell for vxWorks system

Abstract

The invention provides a method for realizing telnet of a shell for a vxWorks system, comprising the following steps of: S1, additionally arranging a Telnet server port assembly in a vxworks assembly and protocoling a defaulted transmission control protocol port protocol to another transmission control protocol port as a port number used when a telnet enters the shell; S2, additionally arranging a starting / finishing order in a system order row to be used for calling when the telnet enters or the shell is closed; and S3, after the telnet logs in a conventional order row, executing the starting order and starting a background shell task; logging in a shell environment through a login port of the order row and carrying out shell operation; and after the operation is finished, executing the finishing order and stopping the background shell task. According to the method disclosed by the invention, the order row and the shell can be used at the same time, so as to be convenient for processing a long-distance fault and debugging a function, and accelerate the processing speed of a long-distance problem.

Description

technical field [0001] The invention relates to the field of the vxWorks operating system, and specifically relates to a method for the vxWorks system to realize a remote login shell. Background technique [0002] vxWorks is a set of real-time embedded operating system developed by American Wind River Corporation (WindRiver). Because of its excellent performance, it is widely used in various embedded devices, especially network devices such as EPON, GPON, routers, and switches; shell It is a command parser provided by vxWorks, which is used to directly call various functions and applications of the system. [0003] As we all know, usually any network device with vxWorks operating system has a relatively complete command line system and also supports remote telnet login. During the use of network equipment, there are often problems or failures. When locating and dealing with these problems, it is difficult to locate and solve them only by the upper-level command line or netw...

AI Technical Summary

Problems solved by technology

[0005] 1. The method of input and output redirection through vxworks is very complicated, and it is related to the implementation structure of the specific command line module. In some cases, this method cannot realize the redirection of the shell, and it is impossible to log in to the shell through telnet

[0006] 2. In this way, the command line and the shell cannot be used at the same time, which brings certain difficulties to debugging

[0007] To sum up, there are many problems in the current method of trying to remotely telnet into the shell of the vxWorks system. When switching directly to the shell mode, the output characters are out of order and cannot be used normally; and in this mode, even the normal command line unavailable
