Inappropriate SSH behavior?

Question

SSH

When connecting users via SSH, it writes Access Denied, although the username and password are correct. Moreover, if you connect to the same user via suor ftp, then everything connects perfectly. Please tell me what is the matter, what to do and how to solve the problem ?!

Answer 1

In the /etc/ssh/sshd_config file add " AllowUsers username ".

Answer 2

Run sshd without background and debugging and see what it says about why it's denied.
Possible reasons:
- cipher suites did not agree (rare, but possible - either a very old client or a very old server)
- users are allowed by name, that is, if I have in the config:
AllowUsers rmbackup testonlytt
then at least crack, but no one except these two will connect
