850          no! same error as above!          no! same error as above!
851            the problem is:
852          watch the output of 'perl -V' - at the bottom:
853          <screen>
854            Characteristics of this binary (from libperl):
855              Compile-time options: MULTIPLICITY USE_ITHREADS USE_LARGE_FILES PERL_IMPLICIT_CONTEXT
856              Built under linux
857              Compiled at Feb 17 2003 12:38:57
858              @INC:
859                /etc/perl
860                /usr/local/lib/perl/5.8.0
861                /usr/local/share/perl/5.8.0
862                /usr/lib/perl5
863                /usr/share/perl5
864                /usr/lib/perl/5.8.0
865                /usr/share/perl/5.8.0
866                /usr/local/lib/site_perl
867                .
868          </screen>
869    
870          The bad one is the "old" shared object coming with Time::HiRes for perl-5.6.1 living at
871          /usr/lib/perl5/auto/Time/HiRes/HiRes.so.
872          
873          We have these options:
874            1. delete this stuff
875            2. put a better version at '.'
876            3. place line '/usr/lib/perl/5.8.0' above of '/usr/lib/perl5'
877            4. copy stuff from '/usr/lib/perl/5.8.0' to '/usr/lib/perl5'
878          
879          Hmmm.....
880            I think i'll choose option 1.:
881            x rm -rf /usr/lib/perl5/auto/Time/HiRes
882            (or if you don't wanna be as brute-force)
883            x cd /usr/lib/perl5/auto/Time
884            x mv HiRes HiRes.old
885            
886        => let's try again:      
887          x /etc/init.d/amavis-milter restart
888            Time::HiRes object version 1.42 does not match bootstrap parameter 01.20 at /usr/lib/perl/5.8.0/DynaLoader.pm line 245.
889    
890        => ahhh...  (also testable via 'perl -MTime::HiRes')
891          x dpkg --force-depends -r libtime-hires-perl
892          => my fault! ;-)
893    
894      => so, everything works fine now....
895          x /etc/init.d/amavis-milter restart
896        
897  o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.  o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.
898    
899  o use the [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?  o use a common [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?
900    
901    o use pdumpfs!
902    
903    o what we build seems similar to Torque <-> Maven  (Tangram|XyZ+Data::Storage <-> nfo-libs|rap)
904    
905    o write meta-documentation about why it's required to lift version-numbers of debian-packages
906      -> Why dpkg-liftversion?
907      1. yakka: libxml2!!!
908      2. amavis-milter: razor-1-branch-required
909    
910    o installing pdumpfs as system-wide backup-system:
911      x mkdir -p /home/service/virtual/pdumpfs/var/data
912      x mkdir -p /home/service/virtual/pdumpfs/var/log
913      x cd /usr/local/bin
914      x ln -s /home/service/virtual/pdumpfs/backup .
915    
916    o feature: BrowsableBackup:
917      o missing: authentication via LDAP....
918    
919    o make up toolpack from shortcuts/*, dispatchmail, backup (->pdumpfs), etc...
920      ->packages.service.netfrag.org
921      -->/usr/local/bin
922      
923    o one account - three services:
924      o wiki
925      o news
926      o backup
927      (o ssh) (not-a-must)
928    
929    o dpkg-modcontrol!!!
930    
931    o robinson - purge package dependencies from .deb- or .rpm-packages
932      can alien do that?
933    
934    o rsync working: view from the server-side:
935     3968 ?        R      0:40 rsync --server --sender -vulogDtprz . /home/service/backup/
936    
937    x finally: we have a backup-system!
938      - built on top of pdumpfs (ruby!), gets triggered by cron through shortcut-script 'backup'
939      - backs up:
940        x /home/*   (except /home/service)
941        x /data/bin  (approx. 9.2M)
942        x /data/libs  (approx. 1.7M)
943        x /data/opt  (approx. 27M)
944        o /data/var  (approx. 104M)
945          o mysql-db
946          o news-spool
947        o /data/www  (approx. 126M)
948          x /data/www/virtual/lashlarue  (approx. 28M)
949          x /data/www/virtual/netfrag  (approx. 68M)
950          x /data/www/virtual/wac  (approx. 4M)
951      o productive backup should go to /var/pdumpfs (similar to /var/backup) instead of /home/service/virtual/pdumpfs!!!
952      o prevent recursive backups (what happens if the backup directory itself would be specified to backup???)
953      => #> crontab -e
954            adding line: 03 03 * * * bash /home/service/virtual/agent/backup_all
955      o limit size of files that are backuped without user-request!?! (2MB, 10MB, 100MB, 1G)
956    
957    o establish logfile-rotation with logrotate!!!
958      #> cd /data/www/virtual/lashlarue/log
959      #> gzip access_log
960      #> gzip error_log
961    
962    o more todos:
963      1. clean more diskspace
964        How to find files larger than, hmm, let's say: 512MB?
965        use 'dus'! [Disk Usage Sorter]
966        http://marginalhacks.com/bin/dus
967        x now disk-usage-stats are prepared to be generated at service.netfrag.org (dus/fbf)
968        o /home/uml/skels aufräumen!
969      2. draw more diagrams
970      3. let 'monit' monitor our umls
971      4. make more backups
972    
973    o look in /var/log/syslog after crash! (other logfiles?)
974
