Apache2 Debian Default Page: It works
It works!

This is the default welcome page used to test the correct operation of the Apache2 server after installation on Debian systems. If you can read this page, it means that the Apache HTTP server installed at this site is working properly. You should replace this file (located at /var/www/html/index.html) before continuing to operate your HTTP server.

If you are a normal user of this web site and don't know what this page is about, this probably means that the site is currently unavailable due to maintenance. If the problem persists, please contact the site's administrator.

Configuration Overview

Debian's Apache2 default configuration is different from the upstream default configuration, and split into several files optimized for interaction with Debian tools. The configuration system is fully documented in /usr/share/doc/apache2/README.Debian.gz. Refer to this for the full documentation. Documentation for the web server itself can be found by accessing the manual if the apache2-doc package was installed on this server.

The configuration layout for an Apache2 web server installation on Debian systems is as follows:

/etc/apache2/
|-- apache2.conf
|       `--  ports.conf
|-- mods-enabled
|       |-- *.load
|       `-- *.conf
|-- conf-enabled
|       `-- *.conf
|-- sites-enabled
|       `-- *.conf
          
  • apache2.conf is the main configuration file. It puts the pieces together by including all remaining configuration files when starting up the web server.
  • ports.conf is always included from the main configuration file. It is used to determine the listening ports for incoming connections, and this file can be customized anytime.
  • Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/ directories contain particular configuration snippets which manage modules, global configuration fragments, or virtual host configurations, respectively.
  • They are activated by symlinking available configuration files from their respective *-available/ counterparts. These should be managed by using our helpers a2enmod, a2dismod, a2ensite, a2dissite, and a2enconf, a2disconf . See their respective man pages for detailed information.
  • The binary is called apache2. Due to the use of environment variables, in the default configuration, apache2 needs to be started/stopped with /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not work with the default configuration.
Document Roots

By default, Debian does not allow access through the web browser to any file apart of those located in /var/www, public_html directories (when enabled) and /usr/share (for web applications). If your site is using a web document root located elsewhere (such as in /srv) you may need to whitelist your document root directory in /etc/apache2/apache2.conf.

The default Debian document root is /var/www/html. You can make your own virtual hosts under /var/www. This is different to previous releases which provides better security out of the box.

Reporting Problems

Please use the reportbug tool to report bugs in the Apache2 package with Debian. However, check existing bug reports before reporting a new bug.

Please report bugs specific to modules (such as PHP and others) to respective packages, not to the web server itself.

Leveraging Knowledge Communication for Innovation – Framework, Methods and Applications of Social Network Analysis in Research and Development

Leveraging Knowledge Communication for InnovationThe paradigm of social network analysis (SNA) is widely recognized as a potential approach to analyze, evaluate, and influence communication processes. Here, the author argues that SNA proves useful as a theoretical concept and as a practical tool for knowledge communication in research and development (R&D).

The context of innovative knowledge generation in organizational R&D environments is introduced very broadly with reference to the existing literature. The pragmatic approach of networks is outlined as a powerful concept to grasp the social relationships between individuals as well as between social aggregates for conceptual and analytical purposes.

Based on three case studies, methods of SNA are simplified and illustrated according to their basic steps to meet practical needs and show their usefulness for business practice. Moreover, the book provides examples for interventions and follow-up activities to improve processes of organizational knowledge communication based on SNA.
