It is highly recommended that you have at least Perl version 5.004. You can get the latest perl version from http://cpan.org/src/. Try the direct download link http://cpan.org/src/stable.tar.gz. You can get Perl documentation from the same location (although copious documentation is included in the downloaded Perl distribution). 1.3 CPAN Downloads You can download most of the Perl modules from CPAN. There are many mirrors of this site. The main site’s URL is http://cpan.org/. You may want to search the Perl modules database by using http://search.cpan.org/. Either use the search form, or type in the name of the package the module is distributed in. For example if you are looking for Apache::DumpHeaders, you can type: http://search.cpan.org/search?dist=Apache-DumpHeaders . 1.4 Apache Get the latest Apache webserver and documentation from http://httpd.apache.org. Try the direct download link http://httpd.apache.org/dist/. 1.5 Squid - Internet Object Cache http://www.squid-cache.org/ Squid Linux 2.x Redhat RPMs : http://home.earthlink.net/~intrep/linux/ 1.6 thttpd - tiny/turbo/throttling HTTP server http://www.acme.com/software/thttpd/ 1.7 mod_proxy_add_forward Ask Bjoern Hansen has written the mod_proxy_add_forward.c module for Apache that sets the X-Forwarded-For field when doing a ProxyPass, similar to what Squid does. -

Mai 2005 Hiermit erkl¨areich, die vorliegende Arbeit selbst¨andig verfasst und keine anderen als die angegebenen Literaturhilfsmittel verwendet zu haben. I hereby declare that this thesis is a work of my own, and that only cited sources have been used. Karlsruhe, den 11. Mai 2005 Bj¨ornTackmann Abstract Network services have gained great importance during the last years. Follow- ing the current trend, the number of computers and applications that collabo- rate to provide these services will grow steadily in the future. The dependencies between the collaborating systems along with heterogeneous management inter- faces will continue to increase the complexity of the administration task. This thesis presents a new approach to server configuration management. The inte- gration of the applications into diverse local environments is simplified, and the availability of services is improved by freeing the applications from error-prone tasks.
