   12: This page shows applications and software packages which are secondary (yet
   13: still necessary) to the proper functioning of the LON-CAPA network code.

   44: <FONT SIZE=-1>From the original source web site:
   45: <BR>"Kerberos is a system for authenticating users and services on a network. It is built upon the assumption that the network is "unsafe". For example, data sent over the network can be eavesdropped and altered, and addresses can also be faked. Therefore
   46: they cannot be used for authentication purposes."

   52: <P>
   53: There are good RPMs for kerberos version 5, however many educational
   54: institutions are only compatible with version 4 (and version 4 has its
   55: advantages).

  120: <TD>A Python/TK interface set (orig. Redhat's "anaconda" package) is customized for LON-CAPA specific system maintenance and upgrade.</TD>
  121: <TD>Interfaces have been scripted.  Need to bug-proof data storage and passing between interface screens as well as system file interactions.</TD>

  125: <TD>Complete source-to-CD build</TD>
  126: <TD>Separate from external software package building.  This step is done when 1 command will read, build, compile, package, and burn a CD based on:

  128: <LI>LON-CAPA base source code
  129: <LI>Operating System
  130: <LI>Operating System customizations 
  131: </UL>
  132: in a well-documented working manner.
  133: </TD>
  134: <TD>A key step in all of this is to have all the LON-CAPA base source code automatically build into an RPM.</TD>

  140: <TD>Already have written a setuid-ed (runnable by 'www') /etc/rc.d/init.d/loncontrol script.  Needs to be greatly perfected and enhanced.  Should also continually recheck (and if needed) reinitialize SQL database.</TD>

  146: <TD><TT>loncron</TT> has been used; we've been running it every three hours through crontab.  Still some significant problems, including a slow start-up.</TD>

  150: <TD>Database blocking</TD>
  151: <TD>Handle database requests through a separate parent-child daemon network layer.</TD>
  152: <TD><TT>lonsql</TT> has been written and implemented in some tests of <TT>loncron</TT>.  SQL database requests have been working, but <TT>lonsql</TT> needs to be trained to assess database status better and work with the metadata layer more closely.  In other words, this scheme works, but there's a lot left to do. </TD>
