Description:
------------
Have built new installations of apache 2.2.14 with PHP 5.2.13 to replace previous installation of Apache 2.0 with PHP 4.3.4.
Other functionality has all worked.

We are recieving warning on all file related ftp functions:
Warning: ftp_rawlist() [function.ftp-rawlist]: socket() failed: Protocol not supported (221)

Connection to server and login complete successfully.
When trying to list, put, get any data it fails.

My guess is connection successful on first port but second (data) port not successful?

Test script:
---------------
<?php
$conn_id = ftp_connect("server");
$login_result = ftp_login($conn_id, "user", "pass");
// check connection
if ((!$conn_id) || (!$login_result)) {
    $error_message .= "FTP connection has failed!";
} else {
    echo "FTP pwd: ".ftp_pwd($conn_id). "<br />";
    $remote_list = ftp_rawlist($conn_id, "/home/devdba");
    foreach ($remote_list as $list_item) {
        echo $list_item."<br />";
    }
}
?>


Expected result:
----------------
FTP pwd: /home
item1
item2
item3

Actual result:
--------------
FTP pwd: /home

Warning: ftp_rawlist() [function.ftp-rawlist]: socket() failed: Protocol not supported (221)
