When you perform a
V2V using SCVMM from a VMware ESX 3.5 host and we may get the following error:
The operation on did not complete successfully because of the error: Server sent disconnect message: type 2 (protocol error : too many authentication failures for root)
First, confirm that the VMM server is connected to ESX using the root account and the security certificate is valid. Next, check that SSH login for the root is not disabled.
By default n ESX 3.0 SSH is disabled for the root account on an ESX host for security. That is, the actual sshd service does not allow root logins. Non-root users are able to login with SSH. This is another layer of protection in addition
to the host firewall.
If you can only connect to the ESX host over the network, connect using an SSH client (such as PuTTY) and log in as a user other than root. After you are logged in, switch to the root user with the following command:
Note: If you do not have any other users on the ESX host, you can create a new user by connecting directly to the ESX host with VMware Infrastructure (VI) or vSphere Client. Go to the
Users & Groups tab, right-click on the Users list and select
Add to open the Add New User dialog. Ensure the
Grant shell access to this user option is selected. These options are only available when connecting to the ESX host directly. They are not available if connecting to vCenter Server.
Note: Alternatively, use the command:
