 Posted: Wed Mar 23, 2005 3:21 pm Post subject: Making mod_php / cracklib / cracklib-words / PECL-crack work |
 |
|
I've currently have an apache2 web sever running mod_php and everything is working correctly however when trying to write a php script that makes use of cracklib I run into problems.
I get the following error:
| Code: | Warning: crack_opendict(): Unable to open a crack dictionary in /var/www/localhost/htdocs/test.php on line 3
Unable to open CrackLib dictionary
|
Ive emerged cracklib, cracklib-words, and PECL-crack and I didnt seem to have any problems. I did an emerge --newuse after adding the cracklib use flag, it didnt seem to effect anything.
Here is my php code
| Code: | <?php
// Open CrackLib Dictionary
$dictionary = crack_opendict('/usr/share/dict/cracklib-words')
or die('Unable to open CrackLib dictionary');
// Perform password check
$check = crack_check($dictionary, 'gx9A2s0x');
// Retrieve messages
$diag = crack_getlastmessage();
echo $diag; // 'strong password'
// Close dictionary
crack_closedict($dictionary);
?>
|
This code is directly ripped off from here: http://php.planetmirror.com/manual/en/ref.crack.php with the only change being made to reflect where gentoo likes to put cracklibs dictionary.
Here are my current USE flags:
| Code: | USE="-qt -kde gtk gnome X apache2 mysql php pam ssl xml xml2 berkdb innobd tcpd acpi gd gd-external openssl jpg png gif session cracklib"
|
Here is my /etc/portage/package.keywords
| Code: | net-analyzer/snort ~x86
net-analyzer/acid ~x86
dev-php/jpgraph ~x86
dev-php/PECL-crack ~x86

I'm not using the crack extension, but I am using some other PECL modules -- do you have "extension=crack.so" somewhere in your php.ini?
Also, what does php -m say?

| Try to test your script with register_global on. |

In PHP4 you don't need the PECL modules. Secondly despite what PHP's documentation says opening the dictionary from inside of a php file doesn't seem to work. However if you modify the [crack] section of '/etc/apache2/conf/php.ini' to have the following:
| Code: |
[Crack]
; Modify the setting below to match the directory location of the cracklib
; dictionary files. Include the base filename, but not the file extension.
crack.default_dictionary = "/usr/lib/cracklib_dict"
|
Everything worked after that. |
