Oft ist es wünschenswert einzelen User(gruppen) bei der Bewertung der Verbindungswünsche in's WWW unterschiedlich zu behandeln. So könnten zum Beispiel Schüler und Lehrer, DAUs, Null- Halb- und Stellenleiter wie auch VIPs mit eigenen Filterregelsätzen belegt werden.

Was zunächst kompliziert anmutet, funktioniert recht einfach und auch überschaubar.

Nachdem wir die Erstinstallation und Grundkonfiguration unseres Web-Content-Filters Dansguardian sowie die Optimierung erfolgreich abgeschlossen haben, machen wir uns in diesem Kapitel nun daran, mit Hilfe von Filtergruppen unsere Installation benutzerindividuell anzupassen.

Als erstes definieren wir wieviele Filtergruppen (max. 99) wir verwenden möchten. Diese Filergruppen müssen fortlaufend durchnummerriert werden, von 1 bis 99. Am besten, wir hinterlegen in der Hauptkonfigurationsdatei von Dansguardian gleich den Verwendungszweck der einzelnen Nutzer - hierzu bearbeiten wir die Konfigurationsdatei /etc/dansguardian/dansguardian.conf mit unserem Lieblingseditor.

 # vim /etc/dansguardian/dansguardian.conf

# Filter groups options
# filtergroups sets the number of filter groups. A filter group is a set of content
# filtering options you can apply to a group of users.  The value must be 1 or more.
# DansGuardian will automatically look for dansguardianfN.conf where N is the filter
# group.  To assign users to groups use the filtergroupslist option.  All users default
# to filter group 1.  You must have some sort of authentication to be able to map users
# to a group.  The more filter groups the more copies of the lists will be in RAM so
# use as few as possible.

Die eigentliche Änderungen zur Standardkonfiguration nehmen wir nun, jeweils in der betreffenden Datei dansguardianfn.conf vor.

Die Gruppe 2 werden wir uns nun als Standardgruppe mit einer BYPASS-Funktion einrichten. So werden zwar weiterhin nicht erwünschte Inhalte im Web gesperrt, aber der VIP bekommt eine Möglichkeit, die gesperrte Seite vorübergehend dennoch zu besuchen.

Hierzu wird in der Sperrseite ein entsprechender Hinweis eingefügt:

Zeitlich begrenzten Zugriff auf diese Seite trotzdem ermöglichen? [JA/nein]

Die eigentliche Änderungen zur Standardkonfiguration nehmen wir nun, in der dansguardianf2.conf vor.

threshold = 0

Damit nun, wie oben beschrieben, dem Anwender in der Sperrseite eine entsprechende Sonder-/Ausnahmeregelung zu Gute kommt, müssen wir noch unsere html-Template etwas anpassen.

Zuerst kopieren wir uns das vorhandenen Template:

 # cp /usr/share/dansguardian/languages/german/template.html /usr/share/dansguardian/languages/german/bypasstemplate.html

Anschließend erweitern wir dieses um die -BYPASS-Funktion.

 # vim /usr/share/dansguardian/languages/german/bypasstemplate.html

...
        <br><br>
        <font size=2>
        Zeitlich begrenzten Zugriff auf diese Seite trotzdem erm&ouml;glichen? [<a href="-BYPASS-">JA</a>/nein]
        <br><br><br><br>
...

Somit ergibt sich in Summe folgende Muster BYPASS-Template-Datei:

The available variables are as follows:
- URL- gives the URL the user was trying to get to.
- REASONGIVEN- gives the nice reason (i.e. not quoting the banned phrase).
- REASONLOGGED- gives the reason that gets logged including full details.
- USER- gives the username if known.
- IP- gives the originating IP.
- FILTERGROUP- gives the group number.
- BYPASS- gives URL which allows temporary bypass of denied page
 
You need to remove the space between the - and the variable to use them
in your HTML.  They are there above so extra processing is not required.
 
More example templates are likely to be found on the DansGuardian web site
on the Extras page.

Im Gegensatz zur vorgenannten Möglichkeit eines whitelisting legen wir uns Gruppe 4 als quasi blacklist an, um so bei Bedarf, einzelnen Usern sofort die Berechtigung im WWW zu sörfen entziehen können. Wir brauchen den betreffenden User dann lediglich in der /etc/dansguardian/lists/filtergroupslist in die Gruppe 4 zu versetzen.

Die eigentliche Änderungen zur Standardkonfiguration nehmen wir nun, in der dansguardianf4.conf vor. Wir passen darin folgende Werte an:

• groupmode = 0
• groupname = 'banned_users'

 # vim /etc/dansguardian/dansguardianf4.conf

Somit ergibt sich folgende Konfigurationsdatei für die Filtergruppe 4 mit dem Verwendungszweck banned_users.

Wie eingangs bereits erwähnt, ist es oft wünschenswert einzelen User(gruppen) bei der Bewertung der Verbindungswünsche in's WWW unterschiedlich zu behandeln. So könnten zum Beispiel Schüler und Lehrer, DAUs, Null- Halb- und Stellenleiter wie auch VIPs mit eigenen Filterregelsätzen belegt werden.

#domains in banned list
#Don't bother with the www. or the http://
 
#The bannedurllist is for blocking PART of a site
#The bannedsitelist is for blocking ALL of a site
 
#As of DansGuardian 2.7.3 you can now include
#.tld so for example you can match .gov for example
 
#The 'grey' lists override the 'banned' lists.
#The 'exception' lists override the 'banned' lists also.
#The difference is that the 'exception' lists completely switch
#off *all* other filtering for the match.  'grey' lists only
#stop the URL filtering and allow the normal filtering to work.
 
#An example of grey list use is when in Blanket Block (whitelist)
#mode and you want to allow some sites but still filter as normal
#on their content
 
#Another example of grey list use is when you ban a site but want
#to allow part of it.
 
#To include additional files in this list use this example:
#.Include</etc/dansguardian/anotherbannedurllist>
 
#You can have multiple .Includes.
 
# Time limiting syntax:
# #time: <start hour> <start minute> <end hour> <end minute> <days>
# Example:
##time: 9 0 17 0 01234
# Remove the first # from the line above to enable this list only from
# 9am to 5pm, Monday to Friday.
