Problem with script connecting to FTP using passive mode

[webMasterYoda]

Hi ppl.

 

I have a problem.

 

I am using a PHP script for hot-spot internet accounting. It is connecting to MikroTik's FTP from which it aquires certain file which contains info about hot-spot users internet usage.

But, after reconstruction of our network sript stopped working. It's still connecting to FTP server, but cannot get directory and file list. BTW it is working in passive mode. I am sure about this, because I tested it with another FTP client from the server which is hosting this script.

So, the solution is to force script to connect to MikroTiks FTP server in passive mode. But I am unable to get this done due to my poor knowledge of PHP scripting.

 

 

 

 

 

Here is 2 main files which are important for PHP script

 

 

config.php

So, can someone help me? I really cant this done without your help.

 

Thanx inadvance.

Have you tried ftp_pasv?

[webMasterYoda]

Hi electric.

 

Thanks for your answer.

 

Yes I tried, but I am not sure I putted the tag on the right place.

 

As I said, my knowledge of PHP scripting is very poor.

 

I know that "ftp_pasv" tag is important for this, but I dunno where and how to put it. That is the real problem.

 

Dont laugh on me. Yes I am PHP noob.
