How to enable CAPTCHA (Visual Confirmation) on
Debian PHPBB Forum ver 3.0.2-4
I have a
phpbb forum for a while now and as it's now indexed
in seach engines
Google, Yahoo, Bing, Yandex etc. the forum
is already tortured by dozen of spam bots crawling with requests to
register.
For a few months already I've configured the new registration
requests in the forum to demand adminstrator confirmation.
However my administrator configured email address is receiving tons
of spam (requests of spam bots for new users registration).
The whole purpose of the spam bots are to register on my phpbb
board in order to post spam links and that way increase certain
pages pagerank in search engines, pretty nasty ...
My phpbb forum is happily installed on a
Stable release of
Debian Lenny and my exact installed phpbb3 package version is
3.0.2-4
Luckily this version of phpbb board includes already embedded
support for
Visual Confirmation (e.g. CAPTCHA
support).
In order to enable this support these are the exact steps I had to
follow:
1. Login to phpbb forum with admin user
2. Go to bottom of the forum and click over Administration
Control Panel
3. Navigate to:
GENERAL -> BOARD CONFIGURATION (Visual confirmation
settings)
On the screen which will appear in General options make sure the
following options are set:
Enable visual confirmation for registrations: Enabled
Enable visual confirmation for guest postings
GD Captcha: Yes
GD Captcha foreground noise: Yes
Now simply press the Submit which is located in the bottom
and the CAPTCHA in new user registration on your phpbb forum will
appear.
