I have a php application using NuSOAP on a RHEL5/CentOS dedicated system.
I'm runing into the following error:
2010-10-21 06:23:43.374471 soap_transport_http: entered send() with data of length: 1693
2010-10-21 06:23:43.374510 soap_transport_http: connect connection_timeout 0, response_timeout 30, scheme http, host www.mysite.com, port 2194

I think its related to some httpd configuration - as per http://www.linuxdevelop.com/redhat--fedora-linux-help/fsockopen-error-13-permission-denied-24366.shtml
I found the problem was related to SELinux configuration.
The firewall is enabled on my server: policy type is targeted, enforcing current is checked and HTTPD scripts to connect to the network were not allowed.
Where: Desktop > System Settings > Security Level > SELinux > httpd > HTTPD scripts to connect to the network was unchecked. I checked it and it is working now.
But I wasnt able to find how to modify this directly within the httpd.conf file
