Using My UMM Unix (cda) Account

UMM's Unix computer (cda.morris.umn.edu) is one of the main central systems for UMM users. Your account on this system will be yours to use for the duration of your stay at UMM. You are responsible for proper use of this account. Do NOT allow others to use it. Use for commercial purposes is prohibited.

Interactive logon:

To interactively log on to your account, use Putty or telnet with ssh software from either a Mac or PC.

Important: When you are finished using the Unix server, type exit or logout to end the session.

Student account limitations:

Maximum student disk storage is twenty megabytes (about 20,000,000 characters). If you manage files wisely by deleting unneeded files, or move your files to diskettes, this should be enough disk space. If you exceed your disk quota, your account will stop working (you will no longer be able to log on).

Deleting files and managing your file directory:

If you log in interactively and save files on your Unix account, it is important that you clean your directory periodically. To see a list of your Unix files, type ls at the cda.morris.umn.edu> prompt and press <Enter>. Your files in the directory will list in alphabetical order. To delete a file, type rm filename and press <Enter>. (Example: rm myfile.dat)

Dial-in service from off campus:

You may access email and other UMM network services from off campus via a modem. There are two separate modem pools.

589-4526 connects you for up to 2 hours.

By dialing one of these numbers, you will connect to the next available modem. If all the modems for this number are in use, you will get a busy signal. You will be required to enter your username and password for authorization. See the Computing Services Web site for complete information.

Creating a file and entering data or text:

You can use pico to create or edit files. At the cda.morris.umn.edu> prompt, enter the command pico filename and type the data or text to the file. Use ctrl-x to save and exit the file. Other available editing commands will be shown in the two lines at the bottom of the screen.

Creating Web pages:

Web pages (.html or .htm files), along with any associated files (such as image files), must be located in a directory called public_html. The URL of your files will be http://cda.morris.umn.edu/~ your username. (~ is the tilde character, located above the Tab key on the keyboard.) Use ftp software to transfer files you have created from your desktop computer to the Unix cda server.

Help:

Type man command at the system prompt where command is the topic you want information about. (Example: man ls tells information about list files command.) For more help, stop by Computing Services, telephone 589-6391 or contact the UMM Help Desk
