When I create a user on Gitlab, it creates a regular user on linux and it can login using a regular SSH protocol with same password an user.
How can I disable the SSH login using SSH to desired users? All my server is exposed to that users.
sshd_config file adding this line
DenyUsers username1 username2 username3 username4
DenyUsers separated by spaces. Login is disallowed for user names that match one of the patterns. â*â and â?â can be used as wildcards in the patterns. Only user names are valid; a numerical user ID is not recognized. By default, login is allowed for all users. If the pattern takes the form USER@HOST then USER and HOST are separately checked, restricting logins to particular users from particular hosts.
