# Line 818  o quepasa - Error: AMaViS Line 845  o quepasa - Error: AMaViS

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