#If you entered your password correctly, the main SSH Linux shell should appear where you enter Linux commands.<br><br>The '''Matrix''' server has been configured to allow users to '''only interact with the Linux OS by issuing commands'''. There are various reasons for this, but the main 2 reasons are to '''force students to learn how to issue Linux commands''' as well as '''limitations to remote access to a graphical Linux server''' due to large number of users (students).<br><br>Later in the course, your instructor may demonstrate other ways of accessing '''graphical versions of Linux''', and how to launch a shell terminal.<br><br>You can '''configure''' the SSH application to adjust elements such as the '''window size''' and '''text font type''' and text '''font size'''.
