Linux sets a user to prohibit ssh login
Sometimes we want to be able to prohibit a user from logging in to the system with SSH, especially on cloud servers. Maybe a user’s password is not complicated for ease of use. In order to prevent hackers from brute force cracking, we hope to prohibit the user from remote ssh login. Log in with a user name with a more complicated password and then switch to a user with a simpler password, which is more secure
edit/etc/ssh/sshd_config
Add a line at the bottom of the file
DenyUsers elasticsearch
Restart the sshdservice or restart the host for the setting to take effect
After restarting, try to log in the elasticsearchuser remotely with ssh , and find that you cannot log in. The function is implemented.
