 o quepasa - Error: AMaViS
    x probably because of perl-5.8.0? yes!  --  is it fixed now? let's try...  (again)
        x /etc/init.d/amavis-milter restart
          no! same error as above!
+       the problem is:
+       watch the output of 'perl -V' - at the bottom:
+       <screen>
+         Characteristics of this binary (from libperl):
+           Compile-time options: MULTIPLICITY USE_ITHREADS USE_LARGE_FILES PERL_IMPLICIT_CONTEXT
+           Built under linux
+           Compiled at Feb 17 2003 12:38:57
+           @INC:
+             /etc/perl
+             /usr/local/lib/perl/5.8.0
+             /usr/local/share/perl/5.8.0
+             /usr/lib/perl5
+             /usr/share/perl5
+             /usr/lib/perl/5.8.0
+             /usr/share/perl/5.8.0
+             /usr/local/lib/site_perl
+             .
+       </screen>
+       The bad one is the "old" shared object coming with Time::HiRes for perl-5.6.1 living at
+       /usr/lib/perl5/auto/Time/HiRes/HiRes.so.
+       We have these options:
+. delete this stuff
+. put a better version at '.'
+. place line '/usr/lib/perl/5.8.0' above of '/usr/lib/perl5'
+. copy stuff from '/usr/lib/perl/5.8.0' to '/usr/lib/perl5'
+       Hmmm.....
+         I think i'll choose option 1.:
+         x rm -rf /usr/lib/perl5/auto/Time/HiRes
+         (or if you don't wanna be as brute-force)
+         x cd /usr/lib/perl5/auto/Time
+         x mv HiRes HiRes.old
+     => let's try again:
+       x /etc/init.d/amavis-milter restart
+         Time::HiRes object version 1.42 does not match bootstrap parameter 01.20 at /usr/lib/perl/5.8.0/DynaLoader.pm line 245.
+     => ahhh...  (also testable via 'perl -MTime::HiRes')
+       x dpkg --force-depends -r libtime-hires-perl
+       => my fault! ;-)
+   => so, everything works fine now....
+       x /etc/init.d/amavis-milter restart
  o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.
- o use the [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?
+ o use a common [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?
+ o use pdumpfs!
+ o what we build seems similar to Torque <-> Maven  (Tangram|XyZ+Data::Storage <-> nfo-libs|rap)
+ o write meta-documentation about why it's required to lift version-numbers of debian-packages
+   -> Why dpkg-liftversion?
+. yakka: libxml2!!!
+. amavis-milter: razor-1-branch-required
+ o installing pdumpfs as system-wide backup-system:
+   x mkdir -p /home/service/virtual/pdumpfs/var/data
+   x mkdir -p /home/service/virtual/pdumpfs/var/log
+   x cd /usr/local/bin
+   x ln -s /home/service/virtual/pdumpfs/backup .
+ o feature: BrowsableBackup:
+   o missing: authentication via LDAP....
+ o make up toolpack from shortcuts/*, dispatchmail, backup (->pdumpfs), etc...
+   ->packages.service.netfrag.org
+   -->/usr/local/bin
+ o one account - three services:
+   o wiki
+   o news
+   o backup
+   (o ssh) (not-a-must)
+ o dpkg-modcontrol!!!
+ o robinson - purge package dependencies from .deb- or .rpm-packages
+   can alien do that?
+ o rsync working: view from the server-side:
+?        R      0:40 rsync --server --sender -vulogDtprz . /home/service/backup/
+ x finally: we have a backup-system!
+   - built on top of pdumpfs (ruby!), gets triggered by cron through shortcut-script 'backup'
+   - backs up:
+     x /home/*   (except /home/service)
+     x /data/bin  (approx. 9.2M)
+     x /data/libs  (approx. 1.7M)
+     x /data/opt  (approx. 27M)
+     o /data/var  (approx. 104M)
+       o mysql-db
+       o news-spool
+     o /data/www  (approx. 126M)
+       x /data/www/virtual/lashlarue  (approx. 28M)
+       x /data/www/virtual/netfrag  (approx. 68M)
+       x /data/www/virtual/wac  (approx. 4M)
+   o productive backup should go to /var/pdumpfs (similar to /var/backup) instead of /home/service/virtual/pdumpfs!!!
+   o prevent recursive backups (what happens if the backup directory itself would be specified to backup???)
+   => #> crontab -e
+         adding line: 03 03 * * * bash /home/service/virtual/agent/backup_all
+   o limit size of files that are backuped without user-request!?! (2MB, 10MB, 100MB, 1G)
+ o establish logfile-rotation with logrotate!!!
+   #> cd /data/www/virtual/lashlarue/log
+   #> gzip access_log
+   #> gzip error_log
+ o more todos:
+   x clean more diskspace
+     - How to find files larger than, hmm, let's say: 512MB?
+       use 'dus'! [Disk Usage Sorter]
+       http://marginalhacks.com/bin/dus
+     - now disk-usage-stats are prepared to be generated at service.netfrag.org (dus/fbf)
+     - h1.service.netfrag.org

+     o /home/uml/skels aufr�umen!
+   o draw more diagrams
+   o let 'monit' monitor our umls
+     - together with heartbeat!
+   o make more backups
+     databases: code (repository) and rdbms-sql (mysql)
+ o look in /var/log/syslog after crash! (other logfiles?)
+ o h1.service.netfrag.org:
+   rjoko@h1:/home/uml/helo # monit
+   monit: error while loading shared libraries: libssl.so.2: cannot open shared object file: No such file or directory
+   rjoko@h1:/home/uml/helo # deleeeeete backup!!! is it reeaaady?

+ o search-shortcut to rpmfind.net
+ o request to hetzner:
+   please delete handle "CNO: MM458-ABC"...
+ o update www.netfrag.org
+   o prevent errors like seen on http://netfrag.org/cgi-bin/viewcvs.cgi/joko/virtual/joko_mail/
+ o update www.netfrag.org
+   x HomePage (phpWiki::Index): remove yakka's "to be repaired" - line
+   o Overview: add link to DocumentIndex at section 'Documentation'
+   x update links (jonen's docs/software, etc.)
+   o rename http://netfrag.org/docs/build/ to http://netfrag.org/docs/.build/ or http://netfrag.org/docs/@build/

+ o QoS for apt-get!!!  (http or ftp to x.debian.org or uni-erlangen.de (parse /etc/apt/sources.list!!!))
+ x jonen makes the words: integraded! yeah!
+ o Develop a metadata-model (preferably stored inside an LDAP-daemon),
+   which can hold information about Host <-> vHost <-> Service(s).
+   This would enhance the Host <-> [posix]Account model currently in development.
+   o Also associate the [posix]Accounts with an AddressBook! (AddressBook <-> ProprietaryAddressBook)
+   o Also associate MailRouting with that [posix]Accounts
+   => this has to be implemented:
+. already in development: Host <-> posixAccount, Host <-> MailRouting
+. tbd: Host <-> vHost <-> Service(s)
+. tbd: posixAccount <-> AddressBook
+. tbd: posixAccount <-> MailRouting
+ o use [rss2email|http://www.w3.org/2002/09/rss2email/]
+   -> that's it: news//rss -> rss2email

+     #> cat {mbox-file} | formail -I "" | less
+     from 'man formail':
+        To extract the header from a message:

+     <title>KISS Principle</title>
+     The KISS (Keep It Simple, Stupid) Principle is self-descriptive and recognizes two things:
+. People (including product and service users) generally want things that are simple,
+         meaning easy to learn and use.
+. A company that makes products or furnishes services may find simplicity an advantage
+         for the company as well, since it tends to shorten time and reduce cost.
+         (Where the company is trying to use the principle on behalf of users, however,
+         design time may take longer and cost more, but the net effect will be beneficial since
+         easy-to-learn-and-use products and services tend to be cheaper to produce and service in the long run.)
+     The New Hacker's Dictionary, edited by Eric Raymond, says the the KISS Principle
+     is sometimes cited on a development project to fend off "creeping featurism."

+ o dsu2html: aggregate outputs from dsu to one or more linked html page(s)

+   o ParsedMode (into rss-chunks by diff2rss)
