Ssh Operation failed for node:managed_node.
The connection could not be established.
Reason:Failed to read remote identification
In conjunction with this, you may also notice that running mxagentconfig and selecting

# ssh-keygen -b 2048 -t rsa /* Generate root ssh key */
5.
# ps -elf|fgrep sshd /* Find the sshd PID */
