# Line 818  o quepasa - Error: AMaViS Line 851  o quepasa - Error: AMaViS

853          no! same error as above!          no! same error as above!
854            the problem is:
855          watch the output of 'perl -V' - at the bottom:
856          <screen>
857            Characteristics of this binary (from libperl):
858              Compile-time options: MULTIPLICITY USE_ITHREADS USE_LARGE_FILES PERL_IMPLICIT_CONTEXT
859              Built under linux
860              Compiled at Feb 17 2003 12:38:57
861              @INC:
862                /etc/perl
863                /usr/local/lib/perl/5.8.0
864                /usr/local/share/perl/5.8.0
865                /usr/lib/perl5
866                /usr/share/perl5
867                /usr/lib/perl/5.8.0
868                /usr/share/perl/5.8.0
869                /usr/local/lib/site_perl
870                .
871          </screen>
872    
873          The bad one is the "old" shared object coming with Time::HiRes for perl-5.6.1 living at
874          /usr/lib/perl5/auto/Time/HiRes/HiRes.so.
875          
876          We have these options:
877            1. delete this stuff
878            2. put a better version at '.'
879            3. place line '/usr/lib/perl/5.8.0' above of '/usr/lib/perl5'
880            4. copy stuff from '/usr/lib/perl/5.8.0' to '/usr/lib/perl5'
881          
882          Hmmm.....
883            I think i'll choose option 1.:
884            x rm -rf /usr/lib/perl5/auto/Time/HiRes
885            (or if you don't wanna be as brute-force)
886            x cd /usr/lib/perl5/auto/Time
887            x mv HiRes HiRes.old
888            
889        => let's try again:      
890          x /etc/init.d/amavis-milter restart
891            Time::HiRes object version 1.42 does not match bootstrap parameter 01.20 at /usr/lib/perl/5.8.0/DynaLoader.pm line 245.
892    
893        => ahhh...  (also testable via 'perl -MTime::HiRes')
894          x dpkg --force-depends -r libtime-hires-perl
895          => my fault! ;-)
896    
897      => so, everything works fine now....
898          x /etc/init.d/amavis-milter restart
899        
900  o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.  o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.
901    
902  o use the [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?  o use a common [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?
903    
904    o use pdumpfs!
905    
906    o what we build seems similar to Torque <-> Maven  (Tangram|XyZ+Data::Storage <-> nfo-libs|rap)
907    
908    o write meta-documentation about why it's required to lift version-numbers of debian-packages
909      -> Why dpkg-liftversion?
910      1. yakka: libxml2!!!
911      2. amavis-milter: razor-1-branch-required
912    
913    o installing pdumpfs as system-wide backup-system:
914      x mkdir -p /home/service/virtual/pdumpfs/var/data
915      x mkdir -p /home/service/virtual/pdumpfs/var/log
916      x cd /usr/local/bin
917      x ln -s /home/service/virtual/pdumpfs/backup .
918    
919    o feature: BrowsableBackup:
920      o missing: authentication via LDAP....
921    
922    o make up toolpack from shortcuts/*, dispatchmail, backup (->pdumpfs), etc...
923      ->packages.service.netfrag.org
924      -->/usr/local/bin
925      
926    o one account - three services:
927      o wiki
928      o news
929      o backup
930      (o ssh) (not-a-must)
931    
932    o dpkg-modcontrol!!!
933    
934    o robinson - purge package dependencies from .deb- or .rpm-packages
935      can alien do that?
936    
937    o rsync working: view from the server-side:
938     3968 ?        R      0:40 rsync --server --sender -vulogDtprz . /home/service/backup/
939    
940    x finally: we have a backup-system!
941      - built on top of pdumpfs (ruby!), gets triggered by cron through shortcut-script 'backup'
942      - backs up:
943        x /home/*   (except /home/service)
944        x /data/bin  (approx. 9.2M)
945        x /data/libs  (approx. 1.7M)
946        x /data/opt  (approx. 27M)
947        o /data/var  (approx. 104M)
948          o mysql-db
949          o news-spool
950        o /data/www  (approx. 126M)
951          x /data/www/virtual/lashlarue  (approx. 28M)
952          x /data/www/virtual/netfrag  (approx. 68M)
953          x /data/www/virtual/wac  (approx. 4M)
954      o productive backup should go to /var/pdumpfs (similar to /var/backup) instead of /home/service/virtual/pdumpfs!!!
955      o prevent recursive backups (what happens if the backup directory itself would be specified to backup???)
956      => #> crontab -e
957            adding line: 03 03 * * * bash /home/service/virtual/agent/backup_all
958      o limit size of files that are backuped without user-request!?! (2MB, 10MB, 100MB, 1G)
959    
960    o establish logfile-rotation with logrotate!!!
961      #> cd /data/www/virtual/lashlarue/log
962      #> gzip access_log
963      #> gzip error_log
964    
965    o more todos:
966      1. clean more diskspace
967        How to find files larger than, hmm, let's say: 512MB?
968        use 'dus'! [Disk Usage Sorter]
969        http://marginalhacks.com/bin/dus
970        x now disk-usage-stats are prepared to be generated at service.netfrag.org (dus/fbf)
971        o /home/uml/skels aufräumen!
972      2. draw more diagrams
973      3. let 'monit' monitor our umls
974        together with heartbeat!
975      4. make more backups
976    
977    o look in /var/log/syslog after crash! (other logfiles?)
978
