fsockopen from another IP?

jonno946

hello,

My server has 2 IP addresses assigned to it.

If i fsockopen a connection it always uses the first IP.

How can i select to fsockopen from the second IP?

thanks,

Jonathan

I think that's more of an operating system/network settings configuration issue than a PHP issue, as PHP may simply use whichever network interface the operating system provides upon opening the socket.

There's brief mention of sockets in the [Socket] section of php.ini, but it doesn't look terribly relevant (but may be worth a look, nonetheless).

I know, not terribly helpful, but at least your thread gets bumped.

How are you invoking the script? If you are calling the script via a web browser or a simulated web browser (like wget, lwp, or even PHP's fopen), then what happens when you call the script via the other IP?

For instance, let's say your two IP's are 1.1.1.1 and 2.2.2.2
and you have a php script called connect.php that opens a socket.

What happens when you call http://1.1.1.1/connect.php versus http://2.2.2.2/connect.php

And if that works but you don't want numbers in your domain names, you can have two host names each resolving to a different IP. (ie. www.xxx.com = 1.1.1.1 and www2.xxx.com = 2.2.2.2)

And lastly, if you never wanted the user (or Google) to see you using alternate domain names, you could have Ajax on the client side or a PHP script on the server side calling the fsocket script on the other IP address.

Hi there,

Thanks for the replies.

I am using PHP to write a shell script to connect to a remote client which allows one connection per IP at any one time. I have one (Interface 0) working fine, now i want to try and get a separate script working on Interface 1.

I have been told that this is a PHP rather than an OS issue, as defining the interface is (apparently) possible in perl (although i have no knowledge of perl).

I have tried changing the IP in cpanel however i have been informed that that is still only for incoming connections - outgoing connections still remain using interface 0.

Any ideas?

Thanks.
