<hr/>

  - Unix-Systems
    o learn howto move/maintain /etc of servers at cvs !!
    Debian:
      x search if new packages available, do 'apt-get --dry-run upgrade'! 
       x build small systool script 'apt-get_remote.pl' which do a cronly 'apt-get --dry-run upgrade' and send output via mail
       o review 'apt-get_remote.pl'
         o what's about parsing some response for comand like installing some marked packages


  - QoS (Quality of Services)
    o check it out !

  - Apache/php:
    - apache aliases - redirect '/' to index.php (used for url catching/rewriting)

  - PHP:
    x search for php widget lib
     x APL (http://apl.sourceforge.net) 
       - huge lib in pure C
     x phphtmllib (http://phphtmllib.newsblob.com)
         a mainly widget/render lib, written in php, complete OO-based
         and with nice DataList rendering (abstract source API)
       x integrated with flib
       x wrote some classes to browse data-objects via class DataList (new classes flibRPCDataSource, ObjectList, TsBackend)
         o rename flibRPCDataSource (maybe rework to get more abstract)
         o review ObjectList amd move it to phphhtmllib
       x semi-integraded with class FormBuilder from binarycloud via interface class FormElementsInterface
         x new class DataItem, which render one data object for viewing/editing
       x integrated new FormProcessing classes from phphtmllib (released one day after interface to binaryclouds Formbuilder was written ;)
         x refactored DataItem to use now phphtmllib form processing instead of interface to binarycload
           o review code and move to phphtmllib
     o XOOPS (http://xoops.org)
         XOOPS is a dynamic OO (Object Oriented) based open source portal script written in PHP.
         It is the ideal tool for developing small to large dynamic community websites, intra company portals, 
         corporate portals, weblogs and much more.
     o binarycloud (http://binarycloud.com)
         binarycloud is an enterprise class web application platform. binarycloud shares many of the capabilities of products 
         like Oracle 9i AS (Application Server) and IBM's WebSphere:
         Proper definition of a framework: "A framework supplies the infrastructure and mechanisms that execute a policy for 
         interaction between abstract components with open implementations" 
        - benefits:
            x much code done yet!
        - drawbacks: 
             o not-really 100% clean code
             o complex app which gives you only limited possibilities to use only some classes, so not very modular
   

  - OpenLDAP:
    - Contacts:
      o Evolution: modify/create schema (map Attribute) so the field 'Note' and others can be used

    - PAM + SASL
      o seems pam will only works(will only be activated) if plain passwords are used
      o read more about PAM special in co-operate with SASL !! 

    - Kerberos V
      x use GQ LdapBrowser with SASL to authenticate against ldap
         - this requires a 'kinit <username>' at the shell to get the kerberos ticket
         - ldap will check your ticket pricipial against its acl's !
      o 'libpam-ldap' from Turbo is bad, don't use it !! (remember at 'apt-get upgrade' !!)
      o write this down in some (existing e.g. sendmail?) howto

    - Sendmail
      o research some about sendmail-cluster, 2 mx records, howto to set up second mx/cluster?
       x backup mx:
          - set up second mx at dns
          - add at backup mx place some like this at /etx/mail/mailtertable:
               domain.com     esmtp:[123.123.123.123]
             where the ip points to the system the real user accounts
            and add every domain to /etc/mail/relay-domains:
               domain.com
             o whats about these *open* relaying rules(security ?!?)
       x simple load balancing:
          - set up two(or more) mx records with same priority at dns
          - add at every mx place some like this at /etx/mail/mailtertable:
               domain.com     esmtp:[123.123.123.123]
             where the ip points to the system the real user accounts are
          note: this will do load balancing between eg 2 mail server, but if one fails,
                   there is only a 50% chance that sent messages would arrive
      o change '/etc/init.d/amavisd' to '/etc/init.d/amavis-milter' in howto
      o migrationtools:
        o patch migrationtools for sendmail aliases support (/usr/share/migrationtools/migrate_aliases.pl)
        o create, or search web for, migrationtool for sendmail virtusertable (/usr/share/migrationtools/migrate_virtuser.pl)
        o review patched kerberosV support at /usr/share/migrationtools/migrate_user.pl?
  

  - MySQL:
    o move this to mysql-common-tasks howto
       - Create Database
         :# mysqladmin create <database>
       - Set Privileges on databases(creates user too, if not exists...):
           mysql>grant all on {database}.* to {user} identified by "{pass}";
           mysql>grant all on {database}.* to {user}@{domain} identified by "{pass}";


  - Document saving:
    o remember *.doc is a non-standard, bloated Mircosoft format, use HTML instead !!
       see http://www.fsf.org/philosophy/no-word-attachments.html

  - my documents:
    o convert all howto's to SDF format ( look at 'nfo/doc/computing/sysadmin/linux/example_sdf_howto.sdf' )
    o learn more about Lyx/LaTex
      o convert all howto's to LaTex format ( look at 'nfo/doc/computing/sysadmin/linux/example_latex_howto.lyx' )


  - news.netfrag.org:
    o create remote functions to implement e.g.:
      o a mozilla button for creating new newsgroups


future:
  o build 'black box' to trace for 'spys' at a isdn/internet connection ;)
