command-line

I am using the "ftp" command of linux to send data to a 3rd party provider. This company states that we need to "Disable passive mode in your FTP client", and I confirm it doesn't work in passive mode.

However, when I googled the linux command, I see that the "-p" flag is "the default now for all clients (ftp and pftp) due to security concerns using the PORT transfer mode. The flag is kept for compatibility only and has no effect anymore."

How do I disable passive mode then? And, is it that bad?
