Joomla 2.5.x - reCaptcha - Could not open socket

Postby lightningbit » Sat Nov 10, 2012 11:54 am

Hi,

since a few weeks, on some of my joomla sites, where I use the Joomla built in reCaptcha on the contact form, I suddenly started to get the error message "Could not open socket"

The issue is present in versions anywhere from Joomla 2.5.3 to 2.5.8

To reproduce :
- enable recaptcha for the contact form
- complete the contact form and fill in recaptcha
- hit send
- the error comes immediately after hitting send

I read somewhere this has to do with being on a server with IPV6

How to fix:

/public_html/plugins/captcha/recaptcha/recaptcha.php
on or around line 189:

replace :

Code: Select all

if (($fs = @fsockopen($host, $port, $errno, $errstr, 10)) == false )

by :

Code: Select all

if (($fs = @fsockopen(gethostbyname($host), $port, $errno, $errstr, 10)) == false )


That seems to resolve the issue for now

Not sure how this needs to be rolled up in Joomla next releases
because the fix may not work when you need IPv6
