No prob. I believe FTP clients open 2 ports, 1 out and 1 in (control and data, IIRC).

Your shell login is likely running on a box that will allow the return port to be opened. The web server box (the one running your script), is likely behind a firewall that won't allow the return (data) port to open. You however are succeeding in logging in via the already open control port.

If I missed badly others should correct me :), but it sounds good eh?

Update: Beatnik followed up by pointing out to me more specifically that port (20), the traditional active FTP data port on the ftp server, may be blocked, while port (21), the traditional ftp control channel, may not be.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
