[SOLVED] Some PHP FTP commands won't execute across domains.

[burritobot]

Below is some php code for simply printing the array of filenames within the folder "images" at a certain FTP address.

 

The code works just fine if I use it within the same domain. (i.e. I execute the script on my mediatemple server, and define the FTP info as an FTP account within the same domain).

 

However, when I run the script on my mediatemple account, and define the FTP info on a different domain (a different mediatemple-hosted FTP site, different domain), it does nothing, then times out after 90 seconds.

 

Can anybody tell me what I'm doing wrong?

 

<?php

$ftp_server=<IP address>;
$ftp_user_name =<username>;
$ftp_user_pass =<password>;
// set up basic connection
$conn = ftp_connect($ftp_server) or die("Could not connect");
if(ftp_login($conn,$ftp_user_name,$ftp_user_pass)){
    echo("connected<br>"); //this works no matter what
    echo ftp_systype($conn); //this also works
    print_r(ftp_nlist($conn,"images")); //this makes it hang and timeout after 90 secs
};
ftp_close($conn);

?>

Try adding a timeout to ftp_connect(), and see what happens.  It sounds as if your host may not allow ftp connections to the outside.  If that's the case, they may still allow it via a proxy server.

The thing is, the code in lines 9 and 10 work fine, which means it is actually connecting to the remote server.

 

However, when I uncomment line 11 (using the ftp_nlist() method), thats when it times outs. It also times out when i try to execute other FTP methods, like ftp_get() or ftp_put(). I've changed permissions on both my server and remote server to no avail.

 

However, I still suspect you may be right about my host not accepting certain ftp methods from the outside. I tried adding the timeout to the ftp_connect() and it's doing the same thing, just after 5 seconds, instead of 90.

 

Can you point me in the right direction on how to try this using the proxy server? Myabe that will help.

 

Thanks so much.

Problem solved. All I had to do was connect using passive mode.
