Anti Bot: Captcha Clock

[.LORD.]

A new version have been released.

+ Have been added an error message that notified that the page has expired.
+ Now the register page isn't cacheable. It improves the security and avoids "Send" & "Go Back" -> "Trial and Error". More details here
+ Some images have been improved

hi

can you tell me where to configure this mod for registration? it shows installed under packages but there is no option at registration>settings

Are you using the last Version?

Hi, I'm having trouble getting this mod to work.

The package appears to install okay, but when I try to register, I see the 'What time is it?' question and the text box and the link for 'how to tell the time', but there is no clock image. If I put in a random time it tells me I've failed the test, so it seems like the code is working; I just don't get the clock images.

The instructions say 'A manual edit is REQUIRED for ALL themes (other than SMF Core Default)', but it doesn't say what to change (I'm new to all this). The listed changes in the manual instructions (Register.Template.php, Register.php etc) all appear to have been made, and the files/image folder are present. I'm just using the default Babylon, Classic and Default themes. It doesn't seem to matter which theme is set as default. Forum version is 1.1.10
PHP version: 5.2.9
MySQL version: 5.1.30
Server version: Apache/2.2.11 (Unix) mod_ssl/2.2.11 OpenSSL/0.9.8i DAV/2 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635
GD version: bundled (2.0.34 compatible)


Edit: Further, if I view the Register page (with no clock image) and then go back and do a normal login, instead of the main forum index, I see the clock in the top left of the window. A refresh (F5) then brings up the main forum display.

Any help would be greatly appreciated. 
Thanks.

Copy the /srv/www/htdocs/Themes/default/images/clocks folder to the images folder for your theme.

Fatal error: Call to undefined function imagerotate() in /var/www/smf/Sources/ABClock.php on line 56


[Dharshan]

will look into this mod....looks cool

[Vyache]

Just wondering if there will be an update for SMF 2.0 RC2 ?

The only slite difference is "// Age restriction in effect?" that line with "// Age restriction in effect?"

Thank you~!!!!!! 

This mod allowed my site to go from averaging a dozen spam memberships a day to zero the minute it was installed. We have had one spam registration in 2 months and that was a human and we got him quickly.

This mod ROCKS!!!!!!!! Thank you again.

[SimpleJoe]

Very nice mod, have tried other mods but the bots somehow slipped in. This one finally did the trick. I'm guessing the spammers spend all their time getting bots to read letters and haven't thought of getting them to read an analog clock. great job!

[ripystys]

A desperately required and awesome mod!
Thank you so much!

Ok, so i've got this partially working in SMF 1.1.12 with:

Forum version: SMF 1.1.12
Current SMF version: SMF 1.1.12
PHP version: 5.2.4-2ubuntu5.12
MySQL version: 5.0.51a-3ubuntu5.8
Server version: Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu5.12 with Suhosin-Patch
GD version: 2.0 or higher
Alternative PHP Cache: 3.0.19

  Upon installation i've found I don't have the GD imagerotate function, so I added some logic to use the Imagick extension instead. It's not perfect but it does display a clock that even a bot would have trouble with (face/base rotation at the end of ABClock.php is buggered). What's really needed is to use Imagick to draw the clock from scratch (no pre-made images, maybe if I get time).

  Problem i'm having now is that the MD5 of the $session['field'] doesn't match (but the ereg does) so I had to disable it (the MD5 that is). So it functions for now I think. ereg will be depricated/removed soon so a rewrite may be in order.

  Wondering about the effectiveness of this mod. Anyone?

Hello all,

the Captcha Clock v2.2 works excellent in SMF1.12, but new registrants informed me about a strange behaviour: the clock itself appears after several refrehes only; this is tested with Firefox and Opera (MSIE has a house ban - I don't mess around with nagware).

Any idea what could cause this issue?

Regards,
ripystys

Hi,

Installation went OK, clock and forms shows up - but not text ("What is the time on the Clock?", etc), even with the Modifications.xxx [nofollow] files up. I'm guessing it's coming from my language pack (french utf8), but I don't see how to correct it. Is there a way to know what Modifications.xxx [nofollow] file is my SMF using, so I can replace it with the new one without having to try every file ?


Ripystys, I'm with FF and clock always shows up, sometimes just a bit slowly. Do your registrants wait a sec' before refreshing ?

Hi, I'm having trouble getting this mod to work.

The package appears to install okay, but when I try to register, I see the 'What time is it?' question and the text box and the link for 'how to tell the time', but there is no clock image. If I put in a random time it tells me I've failed the test, so it seems like the code is working; I just don't get the clock images.

I'm having the same problem. My Support and Credits page reads:
Current SMF version: SMF 1.1.14
PHP version: 5.2.9
MySQL version: 5.0.92-community
Server version: Apache
GD version: bundled (2.0.34 compatible)

This would all appear to be compatible. I use only one theme, the default (classic) theme. I have gone through every file listed in the File Edits instructions and confirmed that they all contain the edits. I have placed the clocks directory in the Themes/default/images directory. I even gave the clocks directory and its contents 777 permissions with CHMOD. Everything works (including disabling the Clock Captcha in the Admin screen) except the box that should contain the clock image contains only a broken "X" icon and the ALT text.

I would really like to get this functionality working. Any other suggestions out there?

On second thought, fuggedaboutit. I came up with my own solution. See http://www.simplemachines.org/community/index.php?topic=451750.0

I have installed version 2.2 according to the manual,
but I cannot find it on the administration / verification page
Am I missing something ?

[Gandalf.pt]

Hello there. I really enjoyed using your mod in SMF 1.1.x. Since I got it, bots never had a chance again (and they used to be around a dozen a day). I couldn't get it to work in SMF 2.0.x, though, even doing it manually. Are you planning on updating it?

Thanks in advance,

[phoedran]

I don't know if it's just me having this problem but... I've been trying to register at a site that has the anti-bot clock (not sure which) and there are constantly new members so I guess it's just me. When I go to the register page the clock is always at 12:00 no matter how long I wait or how many times I refresh and it won't accept 12:00 as the answer. I've tried on 3 different computers using IE and Firefox. Any suggestions?

[karlbenson]

try 00:00

[phoedran]

That doesn't work either.

[AragonEi]
