Hello,

I have a strange issue with apache2 ( on ubuntu ), hoping that someone here may be able to shed some light on.

here's the situation;

I've got an apache server on my network: 172.25.0.3 ( no firewall )

I need to connect to make a SOAP call to a server thats on an extension of our network: 172.16.107.2

from the console on the apache server I can ping 172.16.107.2, I can also open up a LYNX ( txt based browser ) to 172.16.107.2 and it connects without an issue, however when I try to connect from apache/php I get "failed to open stream".


how if I take my web server, put it on the exact same ( physical ) as "172.16.107.2" it works no problem.

so all I can think of is that apache has some kind of routing issue?

any ideas at all would be a big help at this point!

Hello Ken,

What PHP function are you using to make the connection?

Some functions are sanitized by various php.ini settings - several directives can block remote connectivity for safety reasons, e.g: allow-url-fopen (http://www.php.net/manual/en/filesystem.configuration.php#ini.allow-url-fopen)

Another test is to trying opening a telnet session from 172.25.0.3 to 172.16.107.2 on the port the SOAP server is running. While the IP is accessible, the port may not be.
