Answer 1

This must mean that you cannot connect through ssh . Do the following to install it:

sudo apt-get install ssh

Then follow instructions.

Then to be sure you can test locally if ssh works properly:

ssh me@localhost

ju@ju-HP-Compaq-dc7900-Small-Form-Factor:~$ ssh ju@localhost
The authenticity of host 'localhost (127.0.0.1)' can't be established.
ECDSA key fingerprint is 60:8e:2b:c2:6d:f8:b9:41:fa:ba:12:ae:a2:5b:30:a6.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.
