New (temp) Account Copied... php_network_getaddresses errors

I just transferred over from one server to a WHM machine and for the time being, I'd like to keep traffic going to the old server until I am certain the new WHM / CPanel server is working correctly.

So [not sure if this was necessary...] but I was afraid the transfer process would start propogating the DNS servers and the traffic would get routed to the new server in a few days... so I deleted the DNS entry... was that a good move? I just want to test using the temporary urls right now.


However, when I use the http:[ip_addess]/~[account name] some pages load fine, while others get many php errors such as:

Code:

Warning: file_get_contents() [function.file-get-contents]: 
php_network_getaddresses: getaddrinfo failed: 
Name or service not known in /home/blah, blah etc....

If I try to use a file_get_contents command for an external page (such as a webservice) I get the error:

Code:

[function.file-get-contents]: 
failed to open stream: 
Permission denied in /home/blah, blah etc....

The machine is a dedicated server running WHM / CPanel X:
WHM 11.23.2 cPanel 11.23.6-R26881
REDHAT Enterprise 5.2 x86_64 on standard - WHM X v3.1.0

Thanks for any help, I'm a newbie at this.

 

Ok, just to rule out the possibility that the cause was due to deleting the DNS record through WHM, I removed the account, then transferred it again, this time leaving the DNS info (since it appears that it won't "steal" traffic from the current "live" website on the old server).

But the problem remains.
It is not an issue with images or relative addressing... basically its the fact that the php call:

Code:

$page = file_get_contents("http://www.yahoo.com");

... fails.

Why is this happening?
In WHM, the "PHP Configuration Editor" (Advanced Mode) shows that allow_url_fopen is on.
