Changing the Password of Your CVS Repository Account

 

To manage course projects (e.g., to retrieve the code we provide for a project) you will need a special account named the "CVS repository account".  You can find your CVS repository account (and associated password) by accessing grades.cs.umd.edu and selecting "Receive Class Account".  Usually your account has the login id csXXXYYY where XXX corresponds to a course number (e.g., 131, 132) and YYY is a number identifying the account.

 

You must change the default password we provide.  To change the password you need to access the computer:

 

linuxlab.csic.umd.edu

 

Use ssh (a program that allows you to connect from a computer (e.g., your PC) to another computer) in order to access linuxlab.csic.umd.edu.  If you don't know how to use ssh (or don't have the software) then read the information we provided below. 

IMPORTANT: Once you have changed your password wait at least half an hour before you try the new password (it takes some time for the change to take effect).

 

PC Users

• If you don't have ssh you can obtain it for free from the following site: F-Secure SSH

• Start F-Secure.  You will see the following window:

 

• Select "File"-->"Connect".   In the dialog box that appears provide the computer name (linuxlab.csic.umd.edu) and your account information.  In the following snapshot the account is cs132001 (use your account and not this one).

• After selecting "Connect" you will see the dialog box asking for the account password:

• After providing your password you will be connected.  Once you are connected you can open a terminal window by selecting "Window"-->"New Terminal"

 

• The following is a snapshot of the terminal window

 

• The command prompt is represented by something similar to "[cs132001@squeamish ~]$". 

• To change the password type kpasswd after the command prompt.

• Provide the information requested (it will ask you for the current password, followed by the new password).

• To exit the terminal just close the window.

Mac Users

 

Mac provides ssh by default.   Open a terminal window and execute the following command:

 

                    ssh -l csXXXYYY linuxlab.csic.umd.edu

 

where csXXXYYY represents your class account.  Notice that the - is followed by lowercase letter L.  The command execution may ask you whether you are sure whether you want to continue connecting; just say yes.

 

At the point you will see the command prompt represented by something similar to: "[cs132001@squeamish ~]$". To change the password:

• Type kpasswd after the command prompt.

• Provide the information requested (it will ask you for the current password, followed by the new password).

• To exit the terminal just close the window.
