Revised 19 May 2011 by D. Bouldin


  • Enter 501 Ferris and use your ECE login/passwd on one of the arc.eecs.utk.edu (0-19) machines
    or setup your PC to login remotedly.

    Login to any of the following machines:

    ada7.eecs.utk.edu
    ada8.eecs.utk.edu
    ada9.eecs.utk.edu

    I. UNIX FUNDAMENTALS

  • To change directory to an existing directory: cd dir1

  • To change directory to the next level up the tree: cd ..

  • To list the contents of the current directory: ls

  • To make a new subdirectory: mkdir dir3

  • To move an old filename to a new filename: mv old_file new_file

  • To move file3 down into dir2: mv file3 dir2

  • To move file3 up one level of the directory tree: mv file3 ..

  • To copy file1 from directory /usr/cad to the current directory denoted by ".": cp /usr/cad/file1 .

  • To remove a file: rm file1

  • To remove a subdirectory and recursively everything below it in the tree: rm -r dir2

  • To view more of a file one page at a time: more file

    Press spacebar to continue to the next page.
    Press q to quit.
    Press b to go back a page.

    Commonly Used UNIX Commands

    II. E-MAIL FORWARDING & FUNDAMENTALS

    I recommend you create a .forward file in your root directory to point to the machine
    you like to use to read your email.
    For example,

    .forward

    dbouldin@utk.edu

    III. EMAIL YOUR PARAGRAPH and CREATE a .PLAN FILE


  • Use an editor (gedit, vi or emacs; not WORD) to write a 100-word paragraph
    on why you are taking this course and what you expect to gain from it.

  • Email a typo-free version of your personal paragraph to "dbouldin@tennessee.edu".

  • Use an editor to create a ".plan" file that you can place in your root directory
    containing the following information.
    Name:
    Address:
    Phone Number:
    Course:
    Anticipated Graduation Term:
    M.S. or Ph.D. Thesis Topic:
    M.S. or Ph.D. Thesis Advisor:
    Assistantship:
    Employer:

    Then, whenever anyone types "finger yourusername", this information can be accessed.
    Try typing "finger bouldin".

    IV. MAKE YOUR OWN WEB PAGES

    First, go to your root directory and type:

    mkdir webhome
    cd webhome
    cp ~bouldin/webhome/551.html .

    Then edit 551.html as required (note 551/651).
    Your page should include items like those in your .plan file
    and in your Homework 1 paragraph on why you are taking this course.
    Please keep everything on this page formal. You may link your home
    page to other pages and then put whatever you wish.

    Ask another student in the class to check what you have done by accessing:

    http://web.eecs.utk.edu/~username/551.html

    where "username" is your own.

    For example:

    http://web.eecs.utk.edu/~bouldin/551.html

    Scott Fields

    You should also create a protected website that requires a username and password to access.
    It is intended for material that only you and I need to see and not other students.
    To create yours,
    (1) Edit your public page to point to the private page
    cd ~your_username/webhome
    gedit 551.html
    INSERT: a href="protected/551/index.html">PROTECTED WEBSITE
    (2) Create a protected subdirectory and one below that for for the private material
    mkdir protected
    chmod 705 protected
    cd protected
    (3) In the protected subdirectory, create .htaccess and .htpasswd files
    CONTENTS of .htaccess: 
    AuthType Basic
AuthName authorization
AuthUserFile /home/your_username/webhome/protected/.htpasswd
AuthGroupFile /dev/null


require user your_username
require user bouldin

    CONTENTS of .htpasswd: 
    bouldin:byaShdv/TCtEE
your_username:goxLFUKzdrvsk

    (4) Edit "your_username" to be your own and replace the temporary password
    I have for you with one of your choosing.

    To generate a password, type:

    perl -e 'print crypt("govolsgo","go");'

    The following will be printed on the screen:

    goxLFUKzdrvsk

    In general, you type: perl -e 'print crypt("password","salt");'
    where password is obvious and salt is a 2 character string.
    mkdir 551
    (5) Move to that subdirectory and create a index.html file
    cd 551
    gedit index.html
    (6) Put restricted material in the subdirectory and add links in the index.html file.
    (7) Test the access by using Firefox or Internet-Explorer.
    Open the public page. Click on the PROTECTED link.
    A pop-up dialog box should ask you for your username and password.
