ftp

Hi everyone.

Could anyone suggest some explanation to the following:

---- The code ----
$conn_id = ftp_connect('ftp_server_here');
$login_result = ftp_login($conn_id, 'username', 'password');
ftp_pasv($conn_id, true);
$handle = fopen('local_file', "w");
ftp_size($conn_id, 'remote_file');
ftp_fget($conn_id, $handle, 'remote_file', FTP_BINARY);
fclose($handle);
ftp_close($conn_id);
---- Code end ----

I also created the test output of this script:

---- Output ----
Connection ID returned by ftp_connect [line 2151]: Resource id #29
Login result returned by ftp_login [line 2156]: 1
Switching on ftp passive mode...
Checking if it is possible to open file: "............" for writing   ... Success!
File: ............" handler: Resource id #30
Remote file size: 566.0 KB
PHP Warning: ftp_fget(): php_connect_nonb() failed: Connection timed out (110) in ...... on line 2205
---- Output end ----

Then I tried to connect this FTP using shell:

---- Output ----
$ ftp xx.x.xxx.xx
Connected to xx.x.xxx.xx.

local: estonia_downloaded.xml remote: estonia.xml
227 Entering Passive Mode (81,0,233,91,65,138)

---- Output end ----

Why could that happen? Any ideas? Something is wrong with FTP or what...
Thanx
