Getting a GL Account at UMBC
 You MUST have a GL account
 Go to room ECS 020 (in the basement) and ask at the desk, OR
 Using the Internet, go to: accounts.umbc.edu (NO www.)
 Your account can be used in approximately 1/2 hour
CMSC 104, Lecture 01 12

Changing your Linux password
 Login by entering your id and password given on the sheet
 At the Linux prompt type: passwd <Return>
 You will be prompted for your new password; type it in and press <Return>
 You will be asked to type the new password again
CMSC 104, Lecture 01 13

Changing your Linux password
(continued)
 You will be given a message that the password has been changed
 OR you will be given a message that rejects your new password
 Passwords should be at least 5 characters long, should be something you will remember.
 Your password will be rejected if it is a commonly used word or name

Logging on from Home
 High speed line1: 410 - 719 - 1094
 High speed line2: 301 - 322 - 6199 o 56. k bps.
 Settings for both lines o No parity, 8 data bits, 1 stop bit
 On your computer, you must have o Communications software (Free CD Rom from UMBC Computer Services ECS 020) o A modem
CMSC 104, Lecture 01 19

telnet (not used at UMBC), ssh now used
 Connect to your Internet Service Provider
(ISP)
 Windows 95/NT/98/2000 o click: Start o click: Run o Type: telnet linux1.gl.umbc.edu
Login with your
UMBC loginname & password.
CMSC 104, Lecture 01 20

Hardware & Software Needs
 Do I need my own computer?
o No, but it is more convenient for you
 If I have my own computer, can I use it?
o Sure, but you will using it mostly to login to your GL account or for word processing
 Do I need a C Compiler?
o No, and if you buy one, you may be wasting your $$$. All programming should be done in your GL account.
