FTP Ports

Volker over 23 years ago

Why are two FTP Services defined under Definitions | Services (FTP and FTP-Control) ?

I thought FTP uses only Port 21.

Thanks,
Volker

What does FTP-Control mean ? Do I need to enable that port?

Thanks,
Volker

normal ftp uses more than 1 port. It needs a control connection as well as the transfer connection.

Using passive mode ftp may solve this
