captcha in squirrelmail

unix.fresher · 03-14-2010, 04:23 AM

Please help me to insert captcha plugins in squirrelmail.
My installed SquirrelMail version 1.4.20 [SVN]-0.rc2.20100104.fc12
I download tar.gz file and extract it in the plugins directory. After that I executed conf.pl script and installed it.
When I try to login, the page display totally blank.
So please help me.

Hi,
Running conf.pl is not enough.
You should select a backend (meaning a way to create the captcha image), by editing the config.php in the captcha directory.
Read the captcha/docs/INSTALL file for more details.

Thanks bathory,
I read INSTALL file,
I edit config.php file and insert this path there:
$captcha_backend = '/usr/share/squirrelmail/plugins/captcha/backends/textcaptcha';
and also copy textcaptcha_config_example.php to textcaptcha_config.php.
But got no result.
I am very new in Server configuration, please help me.

You don't need the whole path to the file, but only the name of the backend (in your case "textcaptcha"):

Code:

$captcha_backend = 'textcaptcha';

I suggest you to use the "captcha_php" or "watercap" (or you can use the more simpler csi, freecap, opencaptcha backends). All you need to do is to add gd support in php if it doesn't already has it.

unix.fresher · 03-15-2010, 01:31 PM

Thanks bathory,

I changed that path. After that I found the following things in login page:

1. No image or text display in login page
2. A text box with a heading "Enter the text you see in the image above: "
3. I can' login with valid user name & password. Display the error message
"Sorry, you did not provide the correct challenge response."

I read textcaptcha_config.php file but can't understand

then I create an images directory and change its group ownership apache and permission 770 as per INSTALL doc file. But got no result.

As per your advice I tried csi catch but got the previous result. There was no new result found.

bathory · 03-15-2010, 02:04 PM

Are you sure you have installed gd support for php? Since you didn't mention your distro, you should check with your package manager, if you have installed something like php-gd, or php5-gd or similar package.
You can also take a look at your web server logs to see what errors you get.

Sorry bathory for delay reply.
Yes. I am sure

Are you sure you've posted the correct logs? Maybe you're running squirrelmail as a vhost with different log files.
Because I don't see any hit to squirrelmail login.php page

Also since you're running Fedora make sure it's not a SELinux problem

Regards

unix.fresher · 03-18-2010, 12:37 PM

before do anything, I just disable selinux by setenforce 0.
Ok I try to find proper log file.
Please give me two days.

unix.fresher · 03-20-2010, 10:21 PM

sorry friend I can't find any other log file related this. I think am doing some thing wrong in captcha plugins directory. Can you guide me to configure textcaptcha?

This is my config.php in captch directory.

Quote:

$captcha_backend = 'textcaptcha';

Is it any thing to be configure in ./backends/textcaptcha location????
I give here details of that directory:

Quote:

[root@localhost textcaptcha]# pwd
/usr/share/squirrelmail/plugins/captcha/backends/textcaptcha
[root@localhost textcaptcha]# ls -l

bathory · 03-24-2010, 07:17 AM

Sorry for the late reply,
Regarding logs, you should see something like the following in the log files

Quote:

x.x.x.x - - [24/Mar/2010:13:55:22 +0200] "GET /webmail/src/login.php HTTP/1.1" 200 2731
x.x.x.x - - [24/Mar/2010:13:55:22 +0200] "GET /webmail/plugins/captcha/backends/textcaptcha/image_generator.php?sq=1269431722 HTTP/1.1" 200 3865

The only thing I had to change in textcaptcha_config.php in order for textcaptcha to work was the path to x-fonts, as I have a customized xserver installation.

Quote:

$captcha_font_path = '/usr/share/X11/fonts/TTF/';

I have already told you to try a more simple backend, as textcaptcha needs some optional Pear packages in order to work.
For me captcha_php and csi worked out of the box, as the only thing they need is gd support.

Another thing to do is to change ownership to the whole plugons/captcha directory to the user/group apache runs as (I think for fedora is apache:apache):

Code:

chown -R apache:apache /usr/share/squirrelmail/plugins/captcha

Dear bathory
I understand that you really try to help me but, after doing all the thing I get the same result. I attach a screen shot.
I think these are the perfect logs which we want:

You miss the Text_CAPTCHA pear extension. I've already told you that you need to install some extensions in order for textcaptcha to work. From config.php:

Quote:

// textcaptcha Pear Text_CAPTCHA
// See: http://pear.php.net/package/Text_CAPTCHA
// Requires Pear packages:
// Text_Password
// Text_CAPTCHA
// Optional Pear packages:
// Image_Text (highly recommended)
// Numbers_Words
// Text_Figlet

Get at least the 2 required (Text_Password, Text_CAPTCHA) and install them:

Code:

tar zxvf Text_Password-1.1.1.tgz
pear install Text_Password-1.1.1

tar zxvf Text_CAPTCHA-0.4.0.tgz
pear config-set preferred_state alpha
pear install Text_CAPTCHA-0.4.0
pear config-set preferred_state stable

If you think it's a bit complicated, why don't you try the captcha_php that needs no additional extensions to be installed.

Regards
