How does Linux implement remote login through ssh service? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Linux is mostly used in the server, but the server can not be put in the office like PC, they are placed in the IDC computer room, so I usually log in the linux system through remote login.

The remote login function is realized by ssh service in Linux system. The default ssh service is open at port 22, and when we finish installing the system, the service is installed and booted up. So there is no need for us to configure anything else to log in to the linux system directly.

The configuration file for the ssh service is / etc/ssh/sshd_config, which you can modify to implement the ssh service you want. For example, you can change the startup port to 36000.

If you are an windows operating system, Linux remote login requires an additional terminal software to be installed on our machine. At present, the more common terminal login software are SecureCRT, Putty, SSH Secure Shell, etc., many friends like to use SecureCRT because its function is very powerful, and the author likes to use Putty, just because of its small size and very beautiful color display. No.

No matter which client software you use, the ultimate goal is to log in to the linux server remotely. There are many free versions of these software online. You can download one and try it. The following author describes how to use Putty to log in to a remote linux server.

If you downloaded putty, double-click putty.exe and pop up the following window. The putty used by the author is in English. If you find it awkward to use in English, you can download a Chinese version.

Because you are logging in remotely, the server you want to log in must have an IP or hostname. Please enter the remote server IP you want to log in to in the box below Host Name (or IP address) (if your linux does not already have an IP, please set up an IP by yourself, please find it in the following chapters), and then enter.

At this point, we are prompted to enter the user name to log in.

Enter root, then enter, and then enter the password to log in to the remote linux system.

This is the answer to the question about how Linux implements the remote login function through ssh service. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
