Why Am I Seeing the Error Message "Access denied" When I Remotely Log In to a Linux ECS?

Symptom

Possible Causes

• Incorrect username or password.
• A policy that denies logins from user root is enabled on the SSH server.

Solution

• The username or password is incorrect.

  Check the username and password.

• If a policy that denies logins from user root is enabled on the SSH server,
  1. Edit the /etc/ssh/sshd_config file and check the following settings to ensure that the SSH logins from user root are allowed:

     PermitRootLogin yes
     
     

  2. Restart SSH.
     • CentOS 6

       service sshd restart

     • CentOS 7

       systemctl restart sshd
