"how do I get onto the unix machine using SSH (Secure Shell)?"
Answer:  you use a Secure Shell (SSH) client program.
SSH is a secure version of the Telnet specification used for communications on the Internet, where two machines send information to each other over a secure connection. SSH is useful to prevent unauthorized users from gaining access to password and user information that is sent over the Internet.

There are many different SSH client programs that can be freely downloaded on the Internet. However, we recommend using the following programs for their ease of use and the functionality that they provide.
