                      2: <p>
                      3: This document guides you through the process of setting up a new LON-CAPA
                      4: server running SuSE Linux 10.3 with a minimum of packages installed.  
                      5: The computer will be configured solely as a LON-CAPA server and will be 
                      6: expected to have no other services running.  Your server is expected to have a reasonably fast connection to the internet.

                     12: <p>
                     13: Installing Linux is getting easier and easier. You will be required to log in to the machine and execute some routine Unix commands.  Familiarity with the Apache web server, mod_perl, perl, and MySQL are not required to install and run LON-CAPA.

                     35: You will need to know the following network settings for your installation.
                     36: <b>Note:</b>You must have a static IP address to use LON-CAPA.
                     37: DHCP is <em>not</em> supported.

                     48: Installing SuSE 10.3 is quite easy if you've installed Linux products
                     49: before.  Some documentation is available from
