# Geeklog Configuration

## Configuration files

Previous versions of Geeklog used one huge file called `config.php` that held all the core configuration options. As of Geeklog 1.5.0, most of the configuration options have been moved to the database and can now be reached from the Configuration admin panel within Geeklog.

For technical reasons, some configuration options still have to be stored in files. There are two such configuration files now:

- db-config.php
- siteconfig.php

These files are updated when you install Geeklog and you will not normally have to edit them manually.

# Configuration options

Geeklog's configuration options are grouped like this:

- Site
- Stories and Trackback
- Theme
- Blocks
- Users and Submissions
- Images
- Languages and Locale
- Miscellaneous

## Site

### Site: Site

Variable | Default Value | Description
--- | --- | ---
site_url | http://www.example.com | Base URL for your site (no trailing slash)
site_admin_url | http://www.example.com/admin | Base URL of the admin area of your site (no trailing slash). You won't have to change this normally, but some hosting services use a predefined "admin" directory for other purposes. In this case, you can rename Geeklog's `admin` directory and adjust the URL accordingly to avoid conflicts.
site_name | Geeklog Site | Name of your site
site_slogan | Another Nifty Geeklog Site | Slogan for your site. This is added to the HTML title field.
microsummary_short | GL: | Prefix to use for a microsummary.
site_disabled_msg | 'Geeklog Site is down. Please come back soon.' | This contains the message to display when a Geeklog site is disabled. If the text begins with "http:" then visitors are redirected to that URL. Note: The option actually disable the site can be found in the `siteconfig.php` file.
copyrightyear | (disabled) | Set this to the year you want to appear in the copyright notice of your site's footer. If not set, Geeklog will use the current year.
url_rewrite | false | Enable (true) or disable (false) URL rewriting. Also see the section on URL Rewriting below.

### Site: Mail

Variable | Default Value | Description
--- | --- | ---
site_mail | admin@example.com | E-mail address for all admin mail
noreply_mail | noreply@example.com | This is the sender's address of emails sent by the system when users register etc. This should be either the same as $_CONF['site_mail'] or a bouncing address to prevent spammers from getting your email address by registering on the site. If this is NOT the same as above, there will be a message in sent messages that replying to those emails is recommended.
backend | mail | Used to select how to send email. Can be one of 'smtp', 'sendmail', or 'mail'.
sendmail_path | `/usr/bin/sendmail` | If you chose 'sendmail' for the backend setting, this specifies the complete path to the sendmail binary.
sendmail_args | `''` (empty) | If you chose 'sendmail' for the backend setting, this variable can be used to pass additional parameters to the sendmail binary.
host | smtp.example.com | If you chose 'smtp' for the backend setting, this is the SMTP server to use.
port | 25 | If you chose 'smtp' for the backend setting, this is the port number to talk to on the SMTP server.
auth | 0 | If you chose 'smtp' for the backend setting, set this to `1` if your SMTP server requires authorization, and `0` (or leave the field empty) if it doesn't.
username | smtp-username | If you chose 'smtp' for the backend setting, this is the name of your SMTP account.
password | smtp-password | If you chose 'smtp' for the backend setting, this is the password for your SMTP account.

### Site: Syndication

Geeklog can export its headlines to a news feed in various formats (RSS, RDF, and Atom). This will let you share your news with other sites (Hint: Create a Portal block from Geeklog's Block menu to import news feeds from other sites).

Starting with Geeklog 1.3.9, feeds can be created and configured from Geeklog's Admin menu ("Content Syndication"). The following settings will only be used as the default settings for any new feeds that you create from the admin panel.

Variable | Default Value | Description
--- | --- | ---
backend | 1 | Create a feed file for the stories in rdf_file (0=no, 1=yes)
rdf_file | HTML path with "/backend/geeklog.rss" suffix | File system path for the feed file. This file allows you to share your site's headlines with others
rdf_limit | 10 | Limit the number of stories to export to the news feed. If the value for this setting is a number, the feed will hold this many stories. If the number is followed by a lower-case 'h' (e.g. 24h) it denotes the number of hours from which to chose the stories.
rdf_storytext | 0 | If this value is 1, then the entire introtext of the stories will be included in the news feed. Any number greater than 1 limits the introtext to that many characters (e.g. a value of 80 would only include the first 80 characters from the introtext in the feed). If set to 0, the introtext is not included in the feed.
rdf_language | en-gb | Value for the feed's language tag. Depending on your site's language and operating system, this may differ from the language setting in the locale (see above). Example: The PHP locale setting for German is 'de_DE' while the correct language setting for a German RSS feed would be 'de-DE' (note the dash instead of the underscore).
syndication_max_headlines | 0 | Upper limit for the max. number of headlines when importing a feed (into a portal block). The limit can also be set for each individual portal block in the block menu. When set to 0, all headlines are imported.

### Site: Paths

Variable | Default Value | Description
--- | --- | ---
path_html | /path/to/geeklog/public_html/ | Path to your web tree directory for your site (trailing slash necessary). This directory holds all the web pages used by Geeklog.
path_log | /path/to/geeklog/logs/ | File system path for the log files
path_language | /path/to/geeklog/language/ | location of the Geeklog language files
backup_path | /path/to/geeklog/backups/ | location where mysqldump (see above) will store database backups
path_data | /path/to/geeklog/data/ | File system path for the data directory, used e.g. for the user batch add feature
path_images | /path/to/geeklog/public_html/images/ | Path where Geeklog expects to find its images, including user photos and images for stories.

### Site: PEAR

Variable | Default Value | Description
--- | --- | ---
have_pear | `false` | Whether you have PEAR installed on your server (`= true`) or not (`= false`). When set to `false`, Geeklog will use the PEAR packages installed in `$_CONF['path_pear']` (see below)
path_pear | `/path/to/geeklog/system/pear/` | When `$_CONF['have_pear']` (see above) is set to `false`, this is the path where Geeklog expects to find the PEAR packages it requires (e.g. PEAR::Mail for sending emails).

### Site: MySQL

As the name implies, these options are only relevant when your site is running on a MySQL database. They are ignored when using MS SQL.

Variable | Default Value | Description
--- | --- | ---
allow_mysqldump | 1 | Enable or disable the backup functionality (1 = on, 0 = off).
_DB_mysqldump_path | /usr/bin/mysqldump | Complete path to the mysqldump utility (part of MySQL) for making backups of your Geeklog database.
mysqldump_options | -Q | Here you can include additional options for the mysqldump call that Geeklog uses to create a backup from your database.

### Site: Search

Variable | Default Value | Description
--- | --- | ---
num_search_results | 10 | Number of search results per page (and per type).

## Stories and Trackback

### Stories and Trackback: Story

Variable | Default Value | Description
--- | --- | ---
maximagesperarticle | 5 | max. number of images you can have in a story
limitnews | 10 | Number of stories to limit the index page to, this same number will appear in the older stuff block
minnews | 1 | Minimum numbers of stories than can appear on a topic page
contributedbyline | 1 | Show author username to public, and enable search by username (0=no, 1=yes)
hideviewscount | 0 | Whether to show (= 0) or to hide (= 1) the number of views a story has had.
hideemailicon | 0 | When set to 1, this will disable the ability to send a story by email. It will also hide the email icon from stories and the "Email Article To a Friend" from the Story Options block.
hideprintericon | 0 | When set to 1, this will disable display of a story in a "printer friendly" format. It will also hide the printer icon from stories and the "View Printable Version" from the Story Options block.
allow_page_breaks | 1 | Allow usage of the `[page_break]` tag in stories (when set to 1), so that stories can spread over multiple pages.
page_break_comments | last | When the `[page_break]` tag is allowed in stories (see above), where should the story's comments be displayed: `'last'` = on the story's last page only, `'first'` = on the first page only, `'all'` = on every page.
article_image_align | right | Which side of article the topic image should be shown (right or left)
show_topic_icon | 1 | Default setting for new stories and story submissions: Whether to show the topic icon (1) or not (0).
draft_flag | 0 | Default setting for new stories created by Story Admins: Whether the story's draft flag should be set (1) or not (0).
frontpage | 0 | Default setting for new stories and story submissions: Whether the story should appear on the site's frontpage (1) or only in its topic's page (0). Please note that for stories submitted to the archive topic, this setting will be ignored and the story will not appear on the frontpage.
hide_no_news_msg | 0 | When set to 1, hide the "No News To Display" message on the index page (e.g. when viewing a topic without any stories in it)
hide_main_page_navigation | 0 | When set to 1, this option will hide the "Google paging" navigation from index.php, i.e. from the site's frontpage and all topic pages. This may come in handy for more advanced layouts but will of course prevent people from easily reaching older articles.

onlyrootfeatures

0

This restricts the featuring of stories to root user(s). If you have several story admins who can create content that is not visible to other story admins, and such a content is featured, another admin might think its ok to feature his own content. To prevent that two admins unknowingly take features from each other away, only a user who can see all content (= root) should be able to feature a story.

aftersave_story

'list'

Which page to go to after a story has been saved:

- 'item': display the story
- 'list': show admin's list of stories (default)
- 'home': display the site's homepage
- 'admin': go to the "Admin Home" page, i.e. Command & Control

### Stories and Trackback: Trackback

Variable | Default Value | Description
--- | --- | ---
trackback_enabled | true | Enable (true) or disable (true) trackback comments. This applies to both sending and receiving trackback comments.
trackback_code | 0 | Default value for new stories: Trackback enabled (0) or disabled (-1)
trackbackspeedlimit | 300 | Number of seconds between two trackbacks / pingbacks from the same IP address.

check_trackback_link

2

This option can be used to check the validity of a trackback. You can check if the URL in the trackback actually contains a link back to your site (otherwise, it's probably spam). You can also check if the trackback was sent from the proper IP address, i.e. the IP of the site in the trackback URL (again, if they don't match, it's probably spam). Note that you can add up the values below to do more than one check (but using option 1 and 2 doesn't make sense and will be treated as if you requested option 2).
Options are: 0 = don't perform any checks, 1 = check only for your site's main URL (`$_CONF['site_url']`), 2 = check for the exact URL of the entry (e.g. an article) on your site, 4 = check IP address of the sender of the trackback against the site referred to in the trackback URL.
Example: `$_CONF['check_trackback_link'] = 6; // check for the exact URL (2) and proper IP address (4)`

multiple_trackbacks | 0 | How to handle multiple trackbacks and pingbacks from the same source: 0 = keep only the first, reject any further trackbacks / pingbacks; 1 = overwrite, i.e. only keep the latest trackback / pingback; 2 = allow multiple trackbacks / pingbacks, i.e. list them all

### Stories and Trackback: Pingback

Variable | Default Value | Description
--- | --- | ---
pingback_enabled | true | Enable (true) or disable (true) pingback support. This applies to both sending and receiving pingbacks.
pingback_excerpt | true | Unlike Trackbacks, Pingback don't include an excerpt of the text from the site linking to us. When this option is enabled, Geeklog will try and create an excerpt by searching the backlink on the site that sent the Pingback, extract a piece of the text near the link, and use that as the excerpt for the Pingback.

pingback_self

0

Pingbacks are sent out automatically to all the URLs linked from a story - which includes stories on your own site that you may have linked in the article. This option lets you specify how these "self pingbacks" are to be handled: 0 = skip them, i.e. don't send pingbacks to stories on your own site; 1 = allow them, but obey the speed limit; 2 = allow them and ignore the speed limit.
If your article contains more than one link to other stories on your site, then option 1 is probably of limited use, as it would only pingback the first linked story and run into the speed limit for the others.

ping_enabled | true | Enable (true) or disable (true) the ability to ping weblog directory services like Technorati.

## Theme

### Theme: Theme

Variable | Default Value | Description
--- | --- | ---
theme | professional | Default theme to use on the site

menu_elements

`array('contribute', 'calendar', 'search', 'stats', 'directory', 'plugins')`

### Theme: Advanced Settings

Variable | Default Value | Description
--- | --- | ---
show_right_blocks | false | If set to `true`, the right-side column of blocks will be displayed on all pages (instead of only on the index page).
showfirstasfeatured | 0 | When set to 1, this will render the first story on any page using the templates for a featured story, even if that story is not featured. This will even be applied to the first story on page 2 of a topic page, for example.

## Blocks

### Blocks: Admin Block

Variable | Default Value | Description
--- | --- | ---
sort_admin | false | If set to `true` will sort the entries in the Admin's block and the icons on the Submissions page (`moderation.php`) alphabetically.
link_documentation | 1 | Add a link to Geeklog's documentation to the Admin block. Set this to 0 if you don't want that link to show up.
link_versionchecker | 1 | Add a link "GL Version Test" to the Admin block so that you can easily check if your Geeklog version is up to date. Set this to 0 if you don't want that link to show up. Note: The link is only displayed to members of the Root group anyway.

### Blocks: Topics Block

Variable | Default Value | Description
--- | --- | ---

show_servicename | true | If you allow users to log in with accounts on remote services (like LDAP or LiveJournal), this option will at the service's name to the username to avoid confusion with local users of the same name. Set to `false` to disable.
custom_registration | `false` | When set to `true`, Geeklog will let you use your own signup form for new user registrations. Please see the file `lib-custom.php` that ships with Geeklog for an example.
standard | `true` | Whether to allow normal logins into the site, i.e. with a user account that only exists in your site's database.
openid | `false` | Whether to allow logins using OpenID. This will display a special OpenID login below the normal login field. Note: Currently only OpenID 1.1 is supported.

3rdparty

`false`

Allow (when set to `true`) users who already have an account with some other service to log into your Geeklog site with the login for that service. Currently supported: LDAP and LiveJournal.
Please note that to enable login for a specific service, you need an authorization class in `system/classes/authentication`. If you only want to allow LDAP but not LiveJournal users (or vice versa), simply remove the class file for the unwanted service(s).

### Users and Submissions: Spam-X

Variable | Default Value | Description
--- | --- | ---
spamx | 128 | Tells Geeklog's Spam-X plugin what to do when a spam post has been detected. The value is the sum of all values that uniquely identify the Spam-X modules that should be executed. E.g. the "delete" action module uses 128, the "email admin" module uses 8, so if both modules should be executed, this option should be set to 128 + 8 = 136.

### Users and Submissions: Login Settings

Variable | Default Value | Description
--- | --- | ---
lastlogin | `true` | Whether to keep track of when a user last logged in (`= true`) or not (`= false`).
loginrequired | 0 | Login is required to access any part of the site. When set to 1, this overrides the following settings. When you only want to block access to certain parts of the site, set this to 0 and select from the following settings.

### Users and Submissions: User Submission

Variable | Default Value | Description
--- | --- | ---
usersubmission | 0 | Enable (1) or disable (0) the user submission queue (i.e. new users must be approved before they receive their password)
allow_domains | '' | When the user submission queue is enabled this can contain a comma-separated list of domain names from which user submissions will not be queued (but approved automatically). Regular expressions are also allowed and interpreted. Example: `'mycompany.com,myothercompany.com'`

disallow_domains

''

This is the opposite of `$_CONF['allow_domains']` (see above): A list of domain names that are not allowed in email addresses of new users. Note that this list is always used, even when the user submission queue has been switched off. Again, regular expression can be used.
Example disallow email addresses with a certain domain name and from any ".edu" domain: `'somebaddomain.com,\.edu$'`

### Users and Submissions: Submission Settings

Variable | Default Value | Description
--- | --- | ---
storysubmission | 1 | Enable (1) or disable (0) the story submission queue

speedlimit | 45 | Minimum delay between submissions in seconds. This helps prevent Denial of Service (DOS) attacks
skip_preview | 0 | If 1, allows submission of stories and comments without previewing (i.e. the submission form will always have a Preview and a Submit button).
advanced_editor | false | Enable (if set to `true`) a WYSIWYG editor for story and comment submissions and static pages. Geeklog ships with FCKeditor.
wikitext_editor | false | Allow using wiki syntax in stories. This adds a third option, "Wiki-style format", to the Post Mode dropdown in the story editor (implemented using the PEAR::Text_Wiki package).

Variable | Default Value | Description
--- | --- | ---
image_lib | None | Set this to either 'imagemagick', 'netpbm', or 'gdlib' if images should be resized during upload. Leave as 'None' if you don't want images to be resized or if you don't have those packages available.
path_to_mogrify | (disabled) | If you chose 'imagemagick' for `$_CONF['image_lib']` above, then this should hold the complete path to the mogrify executable (from the ImageMagick package), e.g. '/usr/bin/mogrify'. You will need a fairly recent version of ImageMagick for this to work (version 5.4.9 or newer is recommended).
path_to_netpbm | (disabled) | If you chose 'netpbm' for `$_CONF['image_lib']` above, then this should hold the complete path to the directory where the binaries from the Netpbm package are kept, e.g. `'/usr/bin/netpbm/'`. Note that the path must end in a slash. Precompiled binaries for various platforms can be downloaded from the Netpbm homepage.

### Images: Upload

Variable | Default Value | Description
--- | --- | ---
keep_unscaled_image | 0 | Set this to 1 if you want Geeklog to keep the original, unscaled images after upload. The smaller image will then be used as a thumbnail and will link to the original image. Note that this may use a lot of disk space (depending on the size of your images).
allow_user_scaling | 1 | When unscaled images are kept (see above), this option lets the user chose between using the scaled or unscaled image in the story, i.e. enables the `[unscaledX]` image tag (in addition to the `[imageX]` tag).
debug_image_upload | `false` | When set to `true`, this option enables debugging output to be written into Geeklog's `error.log` file during the upload of an image. This is useful to track down problems with the image upload.

### Images: Images in Articles

Variable | Default Value | Description
--- | --- | ---
max_image_width | 160 | Max. width of an image in pixels. If it exceeds this, it is either rejected or resized (depending on the setting of `$_CONF['image_lib']` above).
max_image_height | 120 | Max. height of an image in pixels. If it exceeds this, it is either rejected or resized (depending on the setting of `$_CONF['image_lib']` above).
max_image_size | 1048576 (equals 1 MB) | Max. size of an image in bytes. If it exceeds this, it is is rejected (even if you're using a graphics package to resize images).

### Images: Topic Icons

Variable | Default Value | Description
--- | --- | ---
max_topicicon_width | 48 | Max. width of a topic icon in pixels. If it exceeds this, it is either rejected or resized (depending on the setting of `$_CONF['image_lib']` above).
max_topicicon_height | 48 | Max. height of a topic icon in pixels. If it exceeds this, it is either rejected or resized (depending on the setting of `$_CONF['image_lib']` above).
max_topicicon_size | 65536 (equals 64 KB) | Max. size of a topic icon in bytes. If it exceeds this, it is rejected (even if you're using a graphics package to resize images).

### Images: Photos

Variable | Default Value | Description
--- | --- | ---
max_photo_width | 128 | Max. width of a user photo in pixels. If it exceeds this, it is either rejected or resized (depending on the setting of `$_CONF['image_lib']` above).
max_photo_height | 128 | Max. height of a user photo in pixels. If it exceeds this, it is either rejected or resized (depending on the setting of `$_CONF['image_lib']` above).
max_photo_size | 65536 (equals 64 KB) | Max. size of a user photo in bytes. If it exceeds this, it is rejected (even if you're using a graphics package to resize images).

force_photo_width

(disabled)

This option, when enabled, will only apply when displaying a user photo. The `<img>` tag for the user photo will be emitted with a max. width, as specified by this option. This means that the actual photo can still be larger, but will only be displayed smaller. This is useful for cases where you don't want oddly shaped user photos to break your page's layout (e.g. in a forum).

default_photo | (disabled) | When enabled, this option should point to an image (full URL required!) that should be displayed for users without a user photo. When this option is not set and a user does not have a user photo (or an avatar) then Geeklog will simply not display anything.

### Images: Gravatar

Variable | Default Value | Description
--- | --- | ---
use_gravatar | false | If enabled (set to `true`), a user's avatar image will be requested from gravatar.com if the user didn't upload a user photo (i.e. an uploaded photo always takes priority). Please note that this option may slow down your site on pages that display a lot of userphotos for different users (e.g. forum threads).
gravatar_rating | (disabled) | Avatars submitted to gravatar.com are rated with the rating system used for movies (in the U.S.), i.e. the letters G, PG, R, or X. This option will let you chose the maximum allowed rating for an avatar. For example, a max. rating of R will make sure that no X-rated avatars will be displayed on your site (only G, PG, and R).

## Languages and Locale

### Languages and Locale: Language

Variable | Default Value | Description
--- | --- | ---
language | english | Name of your language file. Additional language files may be available for download at http://www.geeklog.net. If you translate a language file, please send it to us. Also see Localization below.
language_files | (disabled) | For multi-lingual setups only: A list mapping language shortcuts ('en', 'de', etc.) to the Geeklog language files to use.
languages | (disabled) | For multi-lingual setups only: A list mapping language shortcuts ('en', 'de', etc.) to the language's native name ("English", "Deutsch", etc.).

Also see Multi-Language Support in the Geeklog Wiki.

### Languages and Locale: Locale

Variable | Default Value | Description
--- | --- | ---
locale | en_GB | Locale for the system. This defines both the language and the country that PHP will use when deciding how to display localized information such as dates (e.g. for the names of months).
date | %A, %B %d %Y @ %I:%M %p %Z | Date format used for most of the site, including story displays. See date formats below.

## Miscellaneous

### Miscellaneous: Cookies

These variables define the names of all of Geeklog's cookies. They can easily be changed in case there's a name collision with the cookies used by some other software package that you may use on your site.

Variable | Default Value | Description
--- | --- | ---
cookie_session | gl_session | Name of the cookie that stores the session ID.
cookie_name | geeklog | Name of the permanent cookie.
cookie_password | password | Name of the password cookie.
cookie_theme | theme | Name of the theme cookie.
cookie_language | language | Name of the language cookie.
cookie_tzid | timezone | Name of the timezone cookie.
cookie_ip | 0 | Session ID to contain IP address of user as well as random number. This is more secure but will more than likely require dialed up users to login each and every time. (0=no, 1=yes)
default_perm_cookie_timeout | 28800 | Permanent cookie timeout in seconds (28800 = 8 hours).
session_cookie_timeout | 7200 | Session cookie timeout in seconds (7200 = 2 hours).
cookie_path | / | Cookie path (see the PHP manual for details).
cookiedomain | (empty) | The domain that the cookie is available. Geeklog will attempt to guess the correct value for this setting (based on the 'site_url' variable). See the PHP manual for details.
cookiesecure | 0 | Only set to 1 if your site uses HTTPS (see the PHP manual for details).

### Miscellaneous: Miscellaneous

Variable | Default Value | Description
--- | --- | ---
pdf_enabled | 0 | PDF conversion of stories has not been fully implemented yet. Leave this option switched off to prevent unfinished options from showing up on your site.

notification

array()

Send an email notification to `$_CONF['site_email']` when a new story, comment, trackback or pingback has been submitted or a new user has registered with the site. The `array()` can hold any combination of the strings `'story'`, `'comment'`, `'trackback'`, `'pingback'`, and `'user'` (separated by commas), depending on which notification(s) you want.
Example: `array('story','user');` would send notifications when a new story has been submitted or a new user has registered. No notifications would be sent, for example, for new comments.

cron_schedule_interval

86400

Geeklog can emulate a cronjob, i.e. trigger a certain action at a given time. The code to be executed can be provided by a plugin or through the `CUSTOM_runScheduledTask` function in your `lib-custom.php`. The value given is in seconds and specifies the interval in which the code should be executed.
Please note that to trigger this action, you will need to have someone visit your site at around the specified time. On a site with few visitors, the code may only be executed with considerable delay.
Set to 0 to disable.

disable_autolinks | 0 | If set to 1, disables the autolinks. I.e. links using the [story:] etc. syntax are not interpreted any more.

### Miscellaneous: Debug

Variable | Default Value | Description
--- | --- | ---
rootdebug | `false` | When a PHP error occurs, Geeklog's error handler will only display the actual error message to members of the Root group (to prevent leakage of possibly sensitive information). When set to `true`, this information will be displayed to all users. Use only for debugging purposes!

### Miscellaneous: Daily Digest

Variable | Default Value | Description
--- | --- | ---
emailstories | 0 | Let users get stories e-mailed to them (0=no, 1=yes), aka Daily Digest. Please note that this requires cron and the use of PHP as a shell script.
emailstorieslength | 1 | When emailstories (above) is enabled, send only the title and the link to the new stories (0), or send the entire introtext (1) or send the first n characters from the introtext (where n = any other number)
emailstoriesperdefault | 0 | When set to 1, new users will be subscribed to the daily digest automatically when they register with the site.

### Miscellaneous: HTML Filtering

Variable | Default Value | Description
--- | --- | ---
user_html | <p>, <b>, <i>, <a>, <em>, <br>, <tt>, <hr>, <ol>, <ul>, <li>, <code>, <pre> | HTML tags and attributes that normal users are allowed to use in story submissions and comments.
admin_html | additional HTML tags, e.g. for tables | HTML tags and attributes that admin users are allowed to use (in addition to those from user_html). Redefining a tag with additional attributes will overwrite the definition from user_html.
skip_html_filter_for_root | 0 | When set to 1, this will allow members of the Root group to use all HTML in their posts. Use at your own risk!
allowed_protocols | array ('http', 'https', 'ftp'); | Defines which protocols are allowed in links (i.e. HTML `<a>` tags).

### Miscellaneous: Censoring

Variable | Default Value | Description
--- | --- | ---
censormode | 1 | Censor submissions and comments (0 = Disabled, 1 = Enabled, exact matches, 2 = Enabled, match start of word, 3 = Enabled, match fragment)
censorreplace | *censored* | Text to replace a censored word with
censorlist | array(a list of "bad" words goes here ...) | An array of censored words

### Miscellaneous: IP Lookup

Variable | Default Value | Description
--- | --- | ---

ip_lookup

not set

The IP addresses of comment posters are logged and displayed for admin users. When this variable is set to point to a service that can do IP address lookups, it's possible to lookup the owner of an IP address by clicking on it, making it easier to report abuse to ISPs, etc.
`$_CONF['ip_lookup']` should hold the complete URL to the lookup service, with a '`*`' marking the place where the IP address should go. It's also possible to use Tom Willet's NetTools package, in which case the correct setting would be `$_CONF['ip_lookup'] = $_CONF['site_url'] . '/nettools/whois.php?domain=*';`

### Miscellaneous: Webservices

Variable | Default Value | Description
--- | --- | ---
disable_webservices | false | Set this to `true` to disable the webservices.
restrict_webservices | false | Set this to `true` to restrict webservices usage to users with the `webservices.atompub` permission (e.g. those in the predefined "Webservices Users" group).
atom_max_stories | 10 | Max. number of stories returned when an Atom feed is requested through the webservices API.

Also see Using the Webservices in the Geeklog Wiki.

## db-config.php

As the name implies, the file `db-config.php` contains the database configuration. This information is put there during the initial install and you should not normally have to edit this file.

Variable | Default Value | Description
--- | --- | ---
_DB_host | localhost | Database Server (to be entered in the form: hostname:port:unixsocket). In most cases you won't need to change the default value.
_DB_name | geeklog | Database Name
_DB_user | root | Database User Account
_DB_pass | null | Database User Password
_DB_table_prefix | gl_ | Prefix to put in front of all of Geeklog's table names (to avoid name collisions with tables used by other applications)
_DB_dbms | mysql | This option tells Geeklog which type of database it's running on. Can be either `'mysql'` (for MySQL) or `'mssql'` (for Microsoft SQL Server).

## siteconfig.php

The `siteconfig.php` file holds configuration data that can not be stored in the database. Again, most of this information is put there during the installation and you should not normally have to edit this file.

Variable | Default Value | Description
--- | --- | ---
path | /path/to/geeklog/ | Base file system path for your site (trailing slash necessary)
path_system | /path/to/geeklog/system/ | Path to your system directory for your site (trailing slash necessary). This directory holds the code libraries used throughout Geeklog
site_enabled | true | A Geeklog site can be disabled quickly (e.g. for maintenance) by setting this to 'false'. Also see the site_disabled_msg configuration option.
default_charset | iso-8859-1 | Character encoding used by Geeklog when serving HTML pages or sending email. Only used if the language file did not already set another character encoding. For multi-language setups, using `'utf-8'` as the default character set is recommended.

## URL Rewriting

Geeklog includes a simple but useful URL rewriting feature which can help make your site more crawler friendly (i.e. the URLs of your site are more likely to be picked up by the search engine's indexing bots). This feature is supported for URLs to stories, static pages, the article directory, and links.

URL rewriting means that your URLs will look like this

`http://www.geeklog.net/article.php/20021022234959146`

instead of like this

`http://www.geeklog.net/article.php?story=20021022234959146`

While some search engines will pick up the second form, Google seems to prefer the first format and often ignores the second format.

Note: This feature may not work with all web servers. It is known to work with Apache (all versions) and known not to work with IIS (at least some versions). Please try it out before you go public with your site.

## Localization

Localizing Geeklog is fairly easy. All strings are contained in a language file. The default file that ships with the tarball is english.php. People interested in translating Geeklog to other languages are encouraged to join the geeklog-translations mailing list. All important information concerning translating Geeklog will be posted there.

### Locale and Date Formats

You can set the locale and date format in the configuration. To set the locale, set the variable to the proper string or if you leave it blank it will pull the default locale from the operating system. The date formats are handled by your locale. Isn't that smart? Locale names are OS dependent. On most UNIX hosts, you can find locale codes in the /usr/share/locale/locale.alias file and on some systems the command locale -a will display all available locales on a system. If a locale doesn't exist you can create it using the localedef command.
