When I want to connect to port 25 with the fsockopen function, I get Connection refused or Operation timed out error. I get the same error on a hosting I tried for the first time. I'm getting the same error on different hostings at the same time. How can I solve it?
$mxSocket = #fsockopen($mxHost, 25, $errno, $errStr, 2);

Code:
$domain="173.15.180.86";
echo fsockopen($domain, 5904);
The code gives connection refused error. Although when checking on http://www.yougetsignal.com/tools/open-ports/ the port is opened. What could be the reason of it?
Purpose: I want to check whether port is open or dead
I am trying to see whether my port 2195 (apples port) is open for outbound executions. I know that it is closed for inbound. I want to be able to check using php so I wrote this code:
$fp = fsockopen("example.co.uk", 2195, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
fclose($fp);
}
Which returns the error:
Warning: fsockopen(): unable to connect to example.co.uk:2195
(Connection refused) in /home3/.../public_html/.../example.php
on line 13 Connection refused (111)
But as I said I think this is due to the inbound port being closed.
So is there another way to test just the outbound?
I'm testing paypal ipn for a website I am building, but it fails when I try to validate the ipn. In particular this line doesn't work:
$fp = fsockopen('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
the check if (!$fp) fails (fp is false). I assume it can't connect. Why this?
Update
I discovered my hosting solution doesn't support ssl, in fact I get:
Warning: fsockopen() [function.fsockopen]: unable to connect to
ssl://www.sandbox.paypal.com:443 (Unable to find the socket transport
"ssl" - did you forget to enable it when you configured PHP?)
Is there a way to get over this without going for another hosting solution?
You don't have to use SSL (though Paypal highly recommends it.)
$fp = fsockopen('www.paypal.com', 80, $errno, $errstr, 30);
im using fsockopen below:
$socket = fsockopen("uberminecraft.com", 25565, $errno, $errstr, 1);
return ($errno === 0);
Now this should return either false or true if the server is up or not. I know this server is definty up yet i still keep getting an error
Warning: fsockopen() [function.fsockopen]: unable to connect to uberminecraft.com:25565 (Connection timed out)
You have set a timeout of 1 second, is this intentional? Do you know whether the server is able to provide a response fast enough? Have you tried setting a higher timeout?
Also you might want to look at php.net for how to check whether the connection was made.
You must change fsockopen function as follow
$socket = fsockopen("uberminecraft.com", 25565, $errno, $errstr, 30);
Still you are getting same error. please tell to your host provider to open 25565 port.
Thanks
Warning: fsockopen()
[function.fsockopen]: unable to
connect to www.paypal.com:443
(Connection timed out)
This has worked previously? And suddenly has stopped working.
Any ideas?
This is the call:
$fp = fsockopen ('www.paypal.com', 443, $errno, $errstr, 30);
Thanks for any help
According to the error your system is providing, it's timing out on the outbound connection, are you currently able to connect to www.paypal.com on port 443 though something like telnet?
Running something like: telnet www.paypal.com 443 from the local box should show if it's connecting. I strongly suspect that something is blocking port 443 outbound, which is causing your issue, as it's unlikely that PayPal would block you for use of their IPN services.
