Please run the following commands from the console of the jesse vm as 
root and paste your console session (prompts, commands entered, output 
obtained).  If you redact anything, substitute the phrase '<redacted>':

# cat /etc/debian_version

# uname -a

# dpkg-query --show openssh-server

# dpkg-query --show openssh-client

# ls -1 /etc/ssh/*ssh*

# ls -1 /root/.ssh

# egrep -v '^.*#' /etc/ssh/sshd_config | grep .

# ssh localhost

# tail /var/log/auth.log
