FTP fails even though the warning says successful?


I'm using PHP 4.4.4 with Apache 2 on Fedora Core 5. I can use a normal
FTP client to successfully reach an FTP server, but when I execute the
following code, I fail with this error

Warning: ftp_put() [function.ftp-put]: Failed to establish connection.
in /usr/local/apache2/htdocs/super_admin_rs/sa_prod_fns.php on line 96
FTP upload has failed!

Here's the code

// set up basic connection
$conn_id = ftp_connect($ftp_host);
if ($conn_id) {
// login with username and password
$login_result = ftp_login($conn_id,
$ftp_user, $ftp_pwd);
if ($login_result) {
// Disable passive mode
ftp_pasv($conn_id, false);

// upload the file
$remote_path = "$ftp_dir/" .
$upload = ftp_put($conn_id,
$remote_path, $sql_file_path, FTP_ASCII);

// check upload status
if (!$upload) {
die("FTP upload has

What am I doing wrong?

Thanks, - Dave
