870      x probably because of perl-5.8.0? yes!  --  is it fixed now? let's try...  (again)
871          x /etc/init.d/amavis-milter restart
872            no! same error as above!
873          the problem is:
874          watch the output of 'perl -V' - at the bottom:
875          <screen>
876            Characteristics of this binary (from libperl):
877              Compile-time options: MULTIPLICITY USE_ITHREADS USE_LARGE_FILES PERL_IMPLICIT_CONTEXT

889                .
890          </screen>
891    
892          The bad one is the "old" shared object coming with Time::HiRes for perl-5.6.1 living at
893          /usr/lib/perl5/auto/Time/HiRes/HiRes.so.
894          
895          We have these options:
896            1. delete this stuff
897            2. put a better version at '.'
898            3. place line '/usr/lib/perl/5.8.0' above of '/usr/lib/perl5'
899            4. copy stuff from '/usr/lib/perl/5.8.0' to '/usr/lib/perl5'
900          
901          Hmmm.....
902            I think i'll choose option 1.:
903            x rm -rf /usr/lib/perl5/auto/Time/HiRes
904            (or if you don't wanna be as brute-force)
905            x cd /usr/lib/perl5/auto/Time
906            x mv HiRes HiRes.old
907            
908        => let's try again:      
909          x /etc/init.d/amavis-milter restart
910            Time::HiRes object version 1.42 does not match bootstrap parameter 01.20 at /usr/lib/perl/5.8.0/DynaLoader.pm line 245.
911    
912        => ahhh...  (also testable via 'perl -MTime::HiRes')
913          x dpkg --force-depends -r libtime-hires-perl
914          => my fault! ;-)
915    
916      => so, everything works fine now....
917          x /etc/init.d/amavis-milter restart
918        
919  o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.  o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.
920    
921    o use a common [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?
922    
923    o use pdumpfs!
924    
925    o what we build seems similar to Torque <-> Maven  (Tangram|XyZ+Data::Storage <-> nfo-libs|rap)
926    
927    o write meta-documentation about why it's required to lift version-numbers of debian-packages
928      -> Why dpkg-liftversion?
929      1. yakka: libxml2!!!
930      2. amavis-milter: razor-1-branch-required
931    
932    o installing pdumpfs as system-wide backup-system:
933      x mkdir -p /home/service/virtual/pdumpfs/var/data
934      x mkdir -p /home/service/virtual/pdumpfs/var/log
935      x cd /usr/local/bin
936      x ln -s /home/service/virtual/pdumpfs/backup .
937    
938    o feature: BrowsableBackup:
939      o missing: authentication via LDAP....
940    
941    o make up toolpack from shortcuts/*, dispatchmail, backup (->pdumpfs), etc...
942      ->packages.service.netfrag.org
943      -->/usr/local/bin
944      
945    o one account - three services:
946      o wiki
947      o news
948      o backup
949      (o ssh) (not-a-must)
950    
951    o dpkg-modcontrol!!!
952    
953    o robinson - purge package dependencies from .deb- or .rpm-packages
954      can alien do that?
955    
956    o rsync working: view from the server-side:
957     3968 ?        R      0:40 rsync --server --sender -vulogDtprz . /home/service/backup/
958    
959    x finally: we have a backup-system!
960      - built on top of pdumpfs (ruby!), gets triggered by cron through shortcut-script 'backup'
961      - backs up:
962        x /home/*   (except /home/service)
963        x /data/bin  (approx. 9.2M)
964        x /data/libs  (approx. 1.7M)
965        x /data/opt  (approx. 27M)
966        o /data/var  (approx. 104M)
967          o mysql-db
968          o news-spool
969        o /data/www  (approx. 126M)
970          x /data/www/virtual/lashlarue  (approx. 28M)
971          x /data/www/virtual/netfrag  (approx. 68M)
972          x /data/www/virtual/wac  (approx. 4M)
973      o productive backup should go to /var/pdumpfs (similar to /var/backup) instead of /home/service/virtual/pdumpfs!!!
974      o prevent recursive backups (what happens if the backup directory itself would be specified to backup???)
975      => #> crontab -e
976            adding line: 03 03 * * * bash /home/service/virtual/agent/backup_all
977      o limit size of files that are backuped without user-request!?! (2MB, 10MB, 100MB, 1G)
978    
979    o establish logfile-rotation with logrotate!!!
980      #> cd /data/www/virtual/lashlarue/log
981      #> gzip access_log
982      #> gzip error_log
983    
984    o more todos:
985      x clean more diskspace
986        - How to find files larger than, hmm, let's say: 512MB?
987          use 'dus'! [Disk Usage Sorter]
988          http://marginalhacks.com/bin/dus
989        - now disk-usage-stats are prepared to be generated at service.netfrag.org (dus/fbf)
990    
991        - h1.service.netfrag.org
992          /dev/hda7             38570848  33162404   5408444  86% /
993    
994    
995        o /home/uml/skels aufräumen!
996      o draw more diagrams
997      o let 'monit' monitor our umls
998        - together with heartbeat!
999      o make more backups
1000        databases: code (repository) and rdbms-sql (mysql)
1001    
1002    o look in /var/log/syslog after crash! (other logfiles?)
1003    
1004    o h1.service.netfrag.org:
1005      rjoko@h1:/home/uml/helo # monit
1006      monit: error while loading shared libraries: libssl.so.2: cannot open shared object file: No such file or directory
1007      rjoko@h1:/home/uml/helo # deleeeeete backup!!! is it reeaaady?
1008    
1009    x h1.service.netfrag.org - ssh-upgrade [security] (2.9p2 -> 2.9.9p2)

1015    
1016    o what about legolas?
1017    
1018    o search-shortcut to rpmfind.net
1019    
1020    o request to hetzner:
1021      please delete handle "CNO: MM458-ABC"...
1022    
1023    o update www.netfrag.org
1024      o prevent errors like seen on http://netfrag.org/cgi-bin/viewcvs.cgi/joko/virtual/joko_mail/
1025    
1026    o update www.netfrag.org
1027      x HomePage (phpWiki::Index): remove yakka's "to be repaired" - line
