FTP cant connect

[serpent]

Hey all,

 

Im trying to create a php script to replicate the following weather radar

http://www.bom.gov.au/products/IDR703.loop.shtml

 

they have supplied people with a ftp (it has no user/pass)

 

ftp://ftp2.bom.gov.au/anon/gen/radar/

 

so this is my code and it wont even connect.

 

<?php


$ftp_server = "ftp2.bom.gov.au";


// set up a connection or die
$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server"); 


?>

I think it might be the ftp itself?

1. If you're in telnet, type ftp ftp2.bom.gov.au ( or see Starting FTP )
2. When prompted for user-id, enter anonymous.
3. When prompted for the password, enter your e-mail address ( or guest )

Works for me as you can see from the log.

Quick example:

 

 

<?php

$conn = ftp_connect("ftp2.bom.gov.au");
if (!$conn) {
   echo "Couldn't connect to server\n";
   return 1;
}

if (ftp_login($conn, "anonymous", "test@example.com")) {
   $files = ftp_nlist($conn, "anon/gen/radar");
   foreach($files as $file) {
      print("File: $file\n");
   }
}

Don't forget to turn passive mode on if the server  required.

$conn = ftp_connect("ftp2.bom.gov.au");
if (!$conn) {
   echo "Couldn't connect to server\n";
   return 1;
}

if (ftp_login($conn, "anonymous", "test@example.com")) {
  // turn passive mode on
   ftp_pasv($conn, true);
   $files = ftp_nlist($conn, "anon/gen/radar");
   foreach($files as $file) {
      print("File: $file\n");
   }
}

I tried both of the examples above and they did not work.

I think I know the issue though, I am currently at work for the next 8 days (we live on site for that duration)
and our wifi has some pretty extensive port blocking, its entirely possible that port 21 is blocked (if the php protocol utilizes that port?)

 

thanks for the quick responses by the way

This isn't filtered ports issue, if so you could get at least the echo of "Couldn't connect to server". If you are running into a blank page, my best guess is that there is no compiled (or it's not installed) ftp enabled support to this version of php and the directive controls whether or not and where PHP outputs errors is set to "display_errors = Off" in the php conf. file.

Try the following,

<?php

error_reporting(E_ALL);
ini_set("display_errors", 1);

if (function_exists(ftp_connect)) {
    echo 'the function is available';
} else {
    echo 'the function is not available';
}
$conn = ftp_connect("ftp2.bom.gov.au");
if (!$conn) {
    echo "Couldn't connect to server\n";
    return 1;
}

if (ftp_login($conn, "anonymous", "test@example.com")) {
// turn passive mode on
    ftp_pasv($conn, true);
    $files = ftp_nlist($conn, "anon/gen/radar");
    foreach ($files as $file) {
        print("File: $file\n");
    }
}

"

I tried the above code, this was the result

Notice: Use of undefined constant ftp_connect - assumed 'ftp_connect' in C:\php\www\index.php on line 6
the function is availableCouldn't connect to server

It may help to point out my setup

 

Windows 7 Ultimate x64

php-5.5.11-Win32-VC11-x86

and i am using the built in web server

 

This is my first attempt at anything ftp related with php, i thought id have to enable an extension dll in the php.ini but none for ftp exist

[jazzman1]

No, everything is just fine. The function name should be quoted as a string parameter - if (function_exists('ftp_connect')), it was my fault. However, I see you get a message of the echo command "Couldn't connect to server", so I thing you might have a filtered ports issue. Try to install some port's scanning tool and check which ports are filtered by your ISP. I cannot recommend you a tool for windows. I'm using nmap on my linux machines, check on the web for a windows packet.

I will re-run the script when i get home from work in 2 days time, I am fairly certain now my work camps wifi has ports blocked.

[serpent]

Thats all it was, the ports at work were blocked.

 

Now i can start formatting it and sorting it, thanks guys
