To access a Linux server, you need to log in. The first prompt you see is the login prompt. Enter your user name at this prompt.
The next prompt is to enter your password.
If you entered everything correctly you are in. If not, you will be presented with the login prompt again.
Both user name and password are case sensitive. The most common mistake people make is to enter their name and password with the wrong case. Normally user names are in all lower case for convience.
You should not leave yourself logged in. To log out, enter either logout or exit.
To change your password
Enter existing password
Enter new password
Enter new password again (to validate)
