After connecting to Internet through your Internet Service Provider (ISP), select the start icon on the desktop of your windows machine, then at the run command type the rvcc2.raritanval.edu (the Web Server for your class) as shown below, then hit the enter key.

When prompted to enter your login password, type your G Number including the letter upper case G. The password does not appear on the screen. When prompted to select a new password, select password that's at least six characters in length and comprising of letters and numeric digits. I often recommend students to use their first and last initials followed by year of birth. ms1975, for example is Mary Smith's password. When asked to reenter the password do that. If you are successfully logged on you should see a $ prompt.
If you type anything incorrectly on a UNIX machine, the delete character is, CTRL and Backspace together. To delete the entire text you typed press CTRL and U.
