If you need to reset the password of a Jenkins Continious Integration server. Stop Jenkins: usually /etc/init.d/jenkins stop edit the config.xml usually: /var/lib/jenkins/config.xml Replace true New false Possibly remove the Authorization configuration Restart the Server: usually /etc/init.d/jenkins start Now your Jenkins is absolutely insecure, you can just go to the web interface and edit users password. Do not forget to change back the security configuration, this could be done by a config.xml backup or through the web interface.

KISS: Zend_Captcha_Image in action

I just had to build in a Captcha to a simple form on a small side, i thought of using the Zend_Captcha_ReCaptcha but also saw some disadvantages. - Re Captcha is the most common used captcha, if anybody will build a universal spam bot, ReCaptcha might be first target to implement. - Re Captcha depends on a service so if you implement it your site will also depend on this service Implementing a Zend_Captcha_Image is pretty simple, it is not looking as nice as Re Captcha but also works. here is the code.

$captchaImgDir = 'path/to/were/images/will/be/written';
$captcha = 'path/to/trueTypeFontFile.ttf';

$this->addElement(new Zend_Form_Element_Captcha('captcha', array(
'captcha' => array(
'captcha' => 'Image',
'height' => '40',
'font' => $captchaFont,
'imgDir' =>$captchaImgDir,
'wordLen' => 3,
'timeout' => 300,
),
)));

The Zend_Captcha_Image has no standard view renderer, that is why we use the render function

<?=$this->formLabel('captcha', 'Security Code')?><br /> <?=$this->form->getElement('captcha')->render() ;?><br />

If there is time, i might implement a ultimate captcha solution, using Randomly choosen Zend_Captcha implementation this means a spambot would also have to implement different solutions.

Shortnote: Disable all Form Fields Zend_Form

nospam@example.com (John Behrens) — Tue, 09 Aug 2011 16:43:12 +0200

It is possible to disable all form fields using Zend Framework Zend_Form class. maybe if the form is already send and you wanna display the data again inside form for optical reasons.

$form = new My_Zend_Form_Class();
foreach ($form->getElements() as $element) {
$element->setAttrib('disabled', true);
$element->setAttrib('readonly',true);
}

This is not a serios possibility to avoid a form beeing send twice a CSRF token would be much more useful.
