• Setting up your account:

  You must be given a username and a password before receiving access to the system. Visit MC 3011 for that purpose.

  Login into your account takes two steps: entering of user's ID and password. For example

  login: j2lastnm
  password:
  logs in the person with username j2lastnm. UNIX is case sensitive. If your username is jimbo, do not enter JIMBO or Jimbo. Your password is never displayed on the screen preventing other users from seeing it! Change your password when you access the system for the very first time. To change your password type:

  passwd
  and follow the dialog:

  Old password: enter your current password
  New password: enter your new password
  Retype new password: re-enter your new password
  

  The password should be changed on a regular base. Do not write it down or tell it to anyone. You should NOT use any personal information such as name, birthday or any word from dictionary as your password. Rather combine it mixing randomly upper and lower cases with non-alphabetic characters.
