=======================
The Course Linux Server
=======================
-IAN! idallen@idallen.ca

The Course Linux Server at net2003.idallen.ca is a dual-redundant
high-availability cluster of two machines located in the basement
of my house in Centretown.  (Algonquin ITS will not let faculty run
Internet-accessible Linux servers on campus.)

Any issues you have regarding the Course Linux Server must be dealt with
*only* through your instructor.  Neither Algonquin ITS nor the Help Desk
know anything about these Linux machines.  All issues, including password
resetting, must be resolved directly with your instructor, either by
posting to the appropriate course news group or by sending email.

The Linux machines are located behind a firewall.  Any time you connect
to this machine remotely using the SSH protocol (including using SCP
or SFTP or PuTTY), you must use the port number "2003" to pass through
the firewall.  If you forget the port number, you will get rejected.

--------------------------
Connecting from Unix/Linux
--------------------------

    To login to the Course Linux machine from the shell prompt at another
    Unix machine (including from Knoppix or from Macintosh OSX), use
    the SSH command with the -p port number option:

       $ ssh -p 2003 -l abcd0123 net2003.idallen.ca
       [...answer yes to accept the host key, if asked...]
       [...enter your Course Linux Server password...]

    Replace the userid abcd0123, above, with your usual Algonquin userid.
    Your instructor can tell you your special Linux password.  The options
    "-p" (port) and "-l" (login userid) must be lower-case letters.

    You may also specify your userid in front of the host name:

       $ ssh -p 2003 abcd0123@net2003.idallen.ca

    If you need your password reset, see your instructor.  Do not go to ITS.

-----------------------
Connecting from Windows
-----------------------

    If you use Windows, you must use the PuTTY program (or other
    SSH-capable program) to connect to net2003.idallen.ca using the
    SSH protocol and port number 2003 (not the default ssh port 22).

    PuTTY requires you to choose the protocol (SSH) *before* you set
    the different port number (use port 2003 for net2003.idallen.ca).
    Choose SSH before setting the port.

--------------------------
Copies of the Course Notes
--------------------------

    You can find a copy of all the course Notes files for NET2003 on the
    Linux Server under directory: ~idallen/public_html/teaching/net2003/
    Pick the sub-directory corresponding to the current term.

    You can copy files from this directory to your own account for
    modification or study, if you like.  (To avoid plagiarism charges,
    you must credit any material that you copy and submit unchanged.)
