Anti Bot: Captcha Clock v2.2

---

A new and unique Anti-Bot Registration Check. Rather than getting registrants filling in letters, have them tell the time on a clock.

Quote from: Karl BensonIt is a cat and mouse game between forum software and bot-creators to secure forums against spam bots.
Using generic/centralised anti-spam measures makes it viable for bot-creators to try to get past them.
If every forum employs completely different anti-bot measures it makes it almost impossible to create bots for mass-automated registration.

Some people think that this MOD is "ugly".
I have tried to make it more agreeable for humans without decreasing the difficulty for bots.
I deleted effects little or not detrimental for bot, and unpleasant for people.
And I added other effects more annoying to bots and less for humans.

REQUIRED: A manual edit is REQUIRED for ALL themes (other than SMF Core Default) which have a custom Register.template.php
If you don't do perform the edit, nobody will be able to register using those themes.

REQUIRES Minimium:
- PHP >= 4.3.2 & GD Library 2.0.34 (or newer)
- Do NOT install the mod if your server does not meet the minimum requirements.
- To check what GD Library your server has goto Admin > Support & Credits
- If you get an all black image or it doesn't appear correctly, you might have a dodgy version of the library.
Please do NOT ask me how to install GD library or upgrade it.  I don't know.

Awesome mod, Karl. Another weapon against spambots is out there!

I've got it up at my smf 2.0 test site (http://devira.info/smf/index.php?action=register) along with Karl's ABRP mod too. Works perfectly! :D

Thanks again, Karl.

Nice mod Karl.

Analog clocks stumping digital bots...Brilliant! 

u should make the numbers on the lock random, cause i think that is easy to a bot to check the arrows positions

I think that might make it too complex.

Some people might struggle to read the time as it is.

Although possibly some more lines could be added to the clock face to throw off bots.  Plus more different types of clock hands.

If you are looking for suggestions (not that you've asked) - rather than randomize the numbers as alejo said, you could just rotate the entire clock up to 90 degrees in either direction. It would still be completely readable, but then the hand positions could not be read as they could be out by as much as 3 hours in either direction. (90 degrees = 3 hrs from 12).

Aside from that suggestion, I wanted to congratulate you, well done!

Nice work

Hey!,

http://www.simplemachines.org/community/index.php?topic=229650.0

I installed this clock thingy yesterday, and today i tryed to remove it but i got a problem. When i uninstalled it its still on the registration page and idk how to remove it. I also tryed to reupload the plugin and then uinstall it agan to see if it would go away. But it did not go away, instead i got 2 clocks now and i really need your guys help to remove it from my reg page.

The url to ur homesite is http://fridaynightcranks.com/forum/index.php

Version Information:
Forum version: SMF
Current SMF version: SMF 1.1.5

Thanks for everybodyes help if theres someone here who can help me.

There is probably an issue with chmod permissions that prevented the mod being uninstalled automatically.

Unfortunately this means you'll have to do it manually by undoing the edits found here
http://custom.simplemachines.org/mods/index.php?action=parse;mod=1134;attach=52169;smf_version=1.1.5

Are you aware that this mod works fine in 1.1.8? No admin CP options if there's supposed to be any, but I just tried it and it works fine for me.

Hi

This MOD have been updated.

Now work fine in SMF 1.1.X and SMF 2 and have new features and fix a little bug.

More info in the changelog   :)

Works for me. I had to edit register.php, but that was no big deal and I had to move the clock images to my themes folder, but neither was that. Works fine.

I'm an airhead. I would've sworn I got no image until I stuck that folder in the theme directory, but I just renamed it there and it works so... you're right :-[

a new way to prevent spams :)

wonder if it works for RC2?

A new version have been released.

This version improve the security (tranks szcoder for notify). Please update.

RC2? XD

In SMF 2 RC1 yes :)

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

QuoteREQUIRED: A manual edit is REQUIRED for ALL themes (other than SMF Core Default) which have a custom Register.template.php
If you don't do perform the edit, nobody will be able to register using those themes.

:)

If that doesn't apply to you check the package parser against your files to make sure all the edits are correct.

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 (http://www.simplemachines.org/community/index.php?topic=203437.msg2084856#msg2084856)
+ Some images have been improved

hi

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.

I have the following version:

php5-cli=5.2.10
php5-gd=5.2.10
smf=1.1.10
mod=2.2

Clock image doesn't show up and when i try to open the clock image in a new tab i get:

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


will look into this mod....looks cool

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~!!!!!!  ;D

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.

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!

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 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 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 ?

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 (http://www.simplemachines.org/community/index.php?topic=451750.0)

When someone try to register, i have an error. Here the error log:

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

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,

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?

try 00:00

That doesn't work either.

guys i have a problem too with the clock

i try to register on a website and the image with the clock is EMPTY,and just tryed it on many pc with crome,ie,firefox and nothing

i need help on how to complete it.i tryed 00:00 and didn't work

hi all, i can't install this MOD to my SMF 2.04 forum too, i have problem when i try to find the "// Are there age restrictions in place?" keyword in "./Themes/default/Register.template.php" this file, it don't have match keyword ,so i can't modify it, some one can help?

May be due to the age of the mod.

As you can see from the list below the mod is not compatible with 2.0.4

1.1.8, 1.1.9, 1.1.10, 2.0 Beta 3 Public, 2.0 Beta 3.1 Public, 2.0 RC1, 2.0 RC1-1, 2.0 RC1.2

I just installed Version 2.2 on SMF 2.0.12
The // Age... line is slightly different in /Themes/default/Register.template.php so I had to manually edit that. No problem.

It is not showing up on the admin Anti-Spam setting page.
Any idea on how to fix this?
