Zen-cart 1.38a CURL install error

[TheFixer]

Hi Guys,

I've had a look around and found some great info, but have not been able to solve my particular issue, so I hope nobody minds me posting this up.

I've been trying to install zen-cart 1.38a on my own personal Fedora linux box, however I am presented with the following errors on the 'Prerequisites' page...

# CURL problems detected: 6 => Couldn't resolve host 'www.zen-cart.com' more info...
# CURL requires SSL support. Please notify webmaster or hosting company. 6 => Couldn't resolve host 'www.zen-cart.com' more info...
# CURL problems detected: 5 => Couldn't resolve proxy 'proxy.shr.secureserver.net' more info...
# CURL requires SSL support. Please notify webmaster or hosting company. 5 => Couldn't resolve proxy 'proxy.shr.secureserver.net' more info...

I've checked my phpinfo which reports..

curl
cURL support enabled
cURL Information libcurl/7.18.2 NSS/3.12.0.3 zlib/1.2.3 libidn/0.6.14

The machine is connected to the internet and I have also successfully called "curl www.zen-cart.com" and received back the zen-cart homepage.

I have also tried browsing to the /extras/curltest.php page on my server but I am greeted with the following response...

6 Couldn't resolve host 'www.zen-cart.com'

Array
(
    [url] => "http://www.zen-cart.com/testcurl.php"
    [http_code] => 0
    [header_size] => 0
    [request_size] => 0
    [filetime] => -1

    [download_content_length] => 0
    [upload_content_length] => 0
    [starttransfer_time] => 0
    [redirect_time] => 0
) 

When I execute curltest.php directly on the server with "php curltest.php" I get a more promising...

    [url] => "http://www.zen-cart.com/testcurl.php"

The weird thing is I can install 1.37 without any problems.

Any help or pointers would be greatly appreciated.

6 => Couldn't resolve host

That means your server's name-resolution service isn't working correctly when PHP invokes CURL

Thanks for your reply. Could you tell me why I don't seem to experience other issues with my DNS, e.g. I can 'ping www.google.com', I can also successfully execute the command 'curl www.zen-cart.com'.

I'd be interested in how I could debug any potentials issues with my name-resolution service?

Finally the fact that curltest.php appears to successfully pass when I execute it manually with the command 'php extras/curltest.php' but appears to fail when I browse to the file i.e. www.<myserver_hostname>/zen-cart/extras.curltest.php'... Would this be at all familar to you?

Thanks again.

It sounds like you're having problems with your webserver's apache configuration.
I suggest getting help on running/configuring your webserver from a forum dedicated to that topic, such as webhostingtalk.com

I've actually found that after a reboot I have CURL errors when invoked from a browser untill I restart httpd. CURL always works as expected from the command line. I'll keep investigating and check out webhostingtalk.com.

Cheers for your help.

I am supposing that when doing this it is from a SU login such as at "root" and that you are installing ZenCart into a setup FQDN domain or virtual host. It is most likely that your VH setup is not resolving correctly. Is this a straight LINUX install or over one of the CP's available?
