What Should I Do If I Cannot Log In to My ECS Using the Initial Password After I Use It for a Period of Time?

Solution

Check whether the remote login page can be displayed.
  • If the login page cannot be displayed, an error may have occurred in the GuestOS process on the ECS. In such a case, contact customer service for troubleshooting.
  • If the login page can be displayed, log in to the OS in single-user mode for troubleshooting. The procedure is as follows:
    • Check whether the password can be changed in single-user mode.

      If the password can be changed, change it and contact customer service to check whether the password has been maliciously changed due to an attack.

    • If the password cannot be changed, verify that the values of hard and soft in /etc/security/limits.conf are not greater than 65535.

      Change the password in single-user mode and try to log in to the ECS again.
