Description
Technical Field
The invention relates to the technical field of embedded Linux equipment debugging, in particular to a remote debugging system and method for embedded Linux equipment.
Background
If the embedded Linux equipment is abnormal during field operation, operation and maintenance personnel usually need to use a personal computer to connect the embedded equipment through a serial port or an Ethernet for debugging. Due to the reasons of equipment installation environment and the like, operation and maintenance personnel often cannot carry out on-site debugging and need to carry out remote debugging. At present, remote debugging is usually performed by means of a public network Ethernet, but remote debugging difficulty of intranet equipment or equipment without a network interface is high.
SSH reverse tunneling is commonly used to access local area network internal devices over a public network. Local area network equipment accessed to a public network can directly access public network equipment, but the public network equipment can not directly access the local area network equipment through SSH (secure Shell), at the moment, the intranet equipment is required to actively establish SSH (secure Shell) connection with the public network equipment, and the public network equipment realizes reverse SSH access through a port mapping function.
Therefore, how to overcome the problem that the embedded Linux device which runs in an intranet environment or has no network interface cannot be remotely debugged is an urgent need in the prior art.
Patent document CN104503907B discloses a remote debugging system for application programs based on linux system. The system comprises local debugging equipment and remote display debugging data terminal equipment, wherein the debugging equipment runs a debugging server program and a debugged application program. When the debugging server program starts the debugging equipment, the shared circular queue data buffer area is created, and the debugging server program is provided for other application programs to access, manage various function interfaces of the shared circular queue data buffer area and start a TCP/IP service function. And the application program writes the generated debugging data into the annular queue data buffer area through the write interface unit and updates the write data position information in the buffer space management unit. The remote display debugging data terminal equipment is connected with the debugging equipment according to the IP address and the port number provided by the debugging server program, and receives the equipment running state, the fault information and the debugging data transmitted back by the debugging equipment so as to achieve the aim of remotely diagnosing the debugging equipment. However, the technical scheme cannot overcome the defect that the embedded Linux equipment which runs in an intranet environment or has no network interface cannot be remotely debugged.
Patent document CN109861950A discloses a method, an apparatus, a device and a storage medium for remote debugging of a device, so as to improve the debugging efficiency of the device. The method comprises the following steps: establishing a mapping relation with debugged equipment; determining debugging request data, packaging the debugging request data according to a Secure Shell (SSH) protocol and forwarding the debugging request data to the debugged equipment; and receiving the debugging response data encapsulated by the SSH protocol, and decapsulating and displaying the encapsulated debugging response data. The cross-platform interaction can be realized, the debugged equipment can be remotely regulated and controlled, and the debugging efficiency is effectively improved. However, the technical scheme cannot overcome the defect that the embedded Linux equipment which runs in an intranet environment or has no network interface cannot be remotely debugged.
