How to modify the Linux remote port/How to modify the SSH port?

1. First we go to Linux remotely

The 2.SSH configuration file is in the/etc/ssh/sshd_config file.

3. We modify the port by editing this file to achieve

Vi/etc/ssh/sshd_config

4. Find the #port 22 line, default port 22

We can remove the previous # and change the 22 to another port

In this way, SSH port is 43999 after restarting SSH.
