    Hi,

    I was connect by ssh to the server vCenter with the root account, and, today, when i tried to connect to the server vCenter by ssh, i receive this error message:

    But, for example, if i try to connect to the server with the root account on Internet, i can connect without problem:

    What is the problem?

    Thanks so much.

    The new version of PuTTY has a new authentication GSSAPI feature. This allows users to log in with out a password but will not mount a users home directory. We have had several users using the new version of PuTTY who could not log in to kerbNFSv4 system.

    To overcome this problem you must disable GSSAPI authentication.

    To do this in PuTTY go to
    Connection –> SSH –> Auth –> uncheck “Attempt Kerberos 5 GSSAPI/SSPI auth (SSH-2)”
    or
    Connection –> SSH –> Auth –> GSSAPI –> uncheck “Allow GSSAPI Authentication (SSH-2 only)”

    See the following images.

    Putty_sshAuthentication

    Putty-gssapi

    Is SSH shell enabled along with Bash from the VAMI?

    Thank you for sharing screen shot.

    I suspect problem in /etc/ssh/sshd_config

    Can you check "PermitRootLogin  should be Yes.

    Hi! How did you get in to modify the files if you could not sign in?

    Good question.  How can you modify /etc/ssh/sshd_config to SSH into the ESXi if you cannot already SSH?
