FTP on UNIX machine for SAP PI

Hi Experts,

I have PI installed on Unix machine,

I have a simple File to file scenario.

IF I have to connect to FTP machine 10.10.10.1, it throws error

Error occurred while connecting to the FTP server "10.10.10.1": java.net.ConnectException: Connection refused

I have installed File Zilla server on the machine,

How do we normally carry out FTP's using XI on Unix mahcines
