-p Use passive mode for data transfers. Allows use of ftp in environ-
ments where a firewall prevents connections from the outside world
back to the client machine. Requires that the ftp server support
the PASV command. [color="DarkOrange"]This 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.
