Why do you need to log in to Linux remotely? Because usually when the company is doing development, Linux is usually used as a server, and the server is usually placed in the computer room. The Linux server is shared by the development team, and the officially launched projects run on the public network, so you need to log in to Linux remotely for daily project management. Or develop.
SSH
The remote login function in the Linux system is implemented through the SSH service. SSH is the abbreviation of Secure Shell. It is a security protocol based on the application layer and transport layer. It was formulated by the Network Working Group of the IETF. Almost all Unix/Linux platforms can run SSH. The default SSH service port number is 22.
To use the SSH service, you need to install the corresponding server and client. If machine A wants to be remotely controlled by machine B, then machine A needs to install an SSH server, and machine B needs to install an SSH client. The relationship between the two is shown in the figure:
Xshell7
Xshell is a powerful remote terminal connection management software that supports SSH1, SSH2, and the TELNET protocol of the Microsoft Windows platform. It can carry out efficient and safe remote connections on multiple terminals, and can also help effectively manage remote servers, allowing users to customize keyboard mapping, supporting VB scripts, uploading or downloading files, dynamic port forwarding and other operations.
There are many Linux remote login clients on Windows systems. The remote login client used in this article is Xshell7. Other remote tools are similar.
