Apache HTTP Server Version 2.2
Description: | Provides a comprehensive overview of the server configuration |
---|---|
Status: | Extension |
Module Identifier: | info_module |
Source File: | mod_info.c |
To configure mod_info
, add the following to your
httpd.conf
file.
<Location /server-info>
SetHandler server-info
</Location>
You may wish to use mod_authz_host
inside the
<Location>
directive to limit access to your server configuration
information:
<Location /server-info>
SetHandler server-info
Order deny,allow
Deny from all
Allow from yourcompany.com
</Location>
Once configured, the server information is obtained by
accessing http://your.host.example.com/server-info
Once mod_info
is loaded into the server, its
handler capability is available in all configuration
files, including per-directory files (e.g.,
.htaccess
). This may have security-related
ramifications for your site.
In particular, this module can leak sensitive information from the configuration directives of other Apache modules such as system paths, usernames/passwords, database names, etc. Therefore, this module should only be used in a controlled environment and always with caution.
You will probably want to use mod_authz_host
to limit access to your server configuration information.
<Location /server-info>
SetHandler server-info
Order allow,deny
# Allow access from server itself
Allow from 127.0.0.1
# Additionally, allow access from local workstation
Allow from 192.168.1.17
</Location>
By default, the server information includes a list of all enabled modules, and for each module, a description of the directives understood by that module, the hooks implemented by that module, and the relevant directives from the current configuration.
Other views of the configuration information are available by
appending a query to the server-info
request. For
example, http://your.host.example.com/server-info?config
will show all configuration directives.
?<module-name>
?config
?hooks
?list
?server
mod_info
provides its information by reading the
parsed configuration, rather than reading the original configuration
file. There are a few limitations as a result of the way the parsed
configuration tree is created:
ServerRoot
,
LoadModule
, and
LoadFile
.Include
,
<IfModule>
and
<IfDefine>
are not
listed, but the included configuration directives are..htaccess
files are
not listed (since they do not form part of the permanent server
configuration).<Directory>
are listed normally, but
mod_info
cannot figure out the line number for the
closing </Directory>
