CS 105: Telnet and Basic UNIX Account Management

Note that telnet and FTP are so fundamental to Internet computing that basic versions of them are built in to Windows95/98/NT as part of the operating system. They are located in the c:\windows\system\ directory.

Ewan telnet and WS_FTP are more full-featured versions that must be installed.

Telnet:

• Launch the Ewan telnet program; operate the Syracuse University Library catalog:
• Press the New button
• For Name type in Syracuse University Catalog
• For Network Address type in summit.syr.edu, then  OK
• Highlight Syracuse University Catalog and press OK
• You may have to hit <Enter>  a few times to open the connection.
• At prompt for username, type summit
• At prompt for password, type library
• Operate the Syracuse computer remotely to look for a book.
• s (=search) will take you back to the initial search screen
• x (=exit) will log you out of the computer

• Do the same to operate the Library of Congress catalog:
• Set the Network Address to locis.loc.gov
• To log out, keep typing 12!

Basic UNIX account management:

• Login to Aurora (aurora.wells.edu) with your UserID and initial password
• Change your password by typing    passwd <Enter>
• Consider how to choose a good password!
• Logout by typing logout <Enter>; then login again with your new password
• Make a new directory for your Web work by typing mkdir public_html  <Enter>
• Check to see your new directory by listing your files and directories by typing ls  <Enter>
• Get a more detailed (=long) view of your files and directories by typing ls -l <Enter>
• Change directory into your new directory by typing cd public_html <Enter>
• Note that your command prompt always tells you where in your directories you are.
• Change directory back up to your home directory by typing cd .. <Enter> [Leave space before ..]
• Run a simple UNIX program to tell your current UserID by typing whoami <Enter>
• Create a simple file by redirecting the output of the date/time program into a file, by typing  
  date  >  testfile  <Enter>
• Read (=catalog!) your new file by typing cat testfile <Enter>
• Prove to yourself that UNIX is case sensitive by trying to read your file, spelling it with a capital letter!
• Check your connection to any other computer on the Internet by typing ping  and the host name or IP address of the remote computer, e.g. ping www.cornell.edu, or ping 207.10.16.3

For homework: Play with UNIX and telnet; and read about FTP.
