Access denied root ssh

[desadi10]

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.

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?
