    9: There are 4 hardware requirements for the current LON-CAPA system.

   17: <LI>all hardware (monitors, ethernet cards, CD-ROMs, motherboard) must
   18: be compatible with RedHat Linux 6.2.  A vendor compatibility list is at

   28: <LI><B>Why can't I run the LON-CAPA system on a Sun Microsystem, 
   29: MacOS-X, Windows-NT, or a LINUX-based system other than RedHat 6.2?</B>
   30: <BR>The short answer is you can run LON-CAPA on most any type of 
   31: computer, but you shouldn't.  The software system of LON-CAPA has
   32: been designed with security and performance in mind.  Unless you are
   33: prepared to understand the configuration details of the LON-CAPA network
   34: layer and security issues specific to your operating system and machine
   35: architecture, you will not be able to run LON-CAPA.  In the long-term,
   36: alternate scenarios of running the LON-CAPA system will add significant
   37: administrative overhead in terms of LON-CAPA software upgrades.
   38: <LI><B>What about firewall configurations?</B>
   39: <BR>Firewall configurations are doable, but not recommended.
   40: This requires detailed understanding of the LON-CAPA network layer, reduces
   41: network connectivity, and may require reconfiguration upon new software
   42: releases
   43: <LI><B>What about load-balancing hardware configurations?</B>
   44: <BR>The good news is that LON-CAPA supports its own load-balancing
   45: of web-delivered content.  The only relevant hardware configuration
   46: is a static IP address and ethernet connection.  LON-CAPA takes care
   47: of the rest.  Load-balancing should not be implemented with
   48: other hardware/software configurations since this would alter the logic
   49: by which LON-CAPA distributes and disseminates resources. 
   50: <LI><B>What about backup tape drives and CD-ROM burners?</B>
   51: <BR>There currently is no defined system of backing up LON-CAPA resources.
   52: It is, however, both easily doable and highly recommended.  Every machine's
   53: /home/httpd/html/res directory should be periodically saved in entirety.
   54: Additionally, you may wish to save other machine-specific configuration
   55: files such as /etc/httpd/conf/access.conf (for a description of these
   56: files, go to <A HREF="http://install.lon-capa.org/3.1/loncapafiles/loncapafiles.html">
   57: http://install.lon-capa.org/3.1/loncapafiles/loncapafiles.html)</A>.  As far as HOW you
   58: save this, via a tape-drive or CD-ROM, that is your currently your
   59: judgement call.  For more information on backing up Linux-based systems,
   60: read <A HREF="http://www.medstv.unimelb.edu.au/~pierre/backup/Backup-HOWTO.html">

   65: <P>
   66: A monitor and other peripherals are not necessary for anything but
   67: the installation process.  Their inclusion with your computer system
   68: is dependent on what level of convenience you think they provide.
