# Line 818  o quepasa - Error: AMaViS Line 842  o quepasa - Error: AMaViS

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