Are you not able to make use of the FTP service which is installed and running in your server?
Check whether ip_conntrack_ftp Kernel module has been installed or not. This is very important as ip_conntack_ftp enables your firewall to identify packets relating to ftp. So this should be loaded into kernel before you make use of FTP service. The module is useful for connections on both FTP data and control ports to be considered state ‘related’, whether you are using active or passive mode
To check whether this module has been loaded or not. run the following command :
lsmod | grep ftp
To insert this module into kernel you can run the following command :
modprobe ip_conntack_ftp
To load this module during the system boot up, you can add this module to /etc/modules file.
There could be some other reason for this issue. Do check the logs etc to get more hint on the issue which you’re facing.
