Refer to "man ftp". Passive FTP is mentioned as follows:
EXTENDED PASSIVE MODE AND FIREWALLS
Some firewall configurations do not allow ftp to use extended passive
mode. If you find that even a simple ls appears to hang after printing a
message such as this:
229 Entering Extended Passive Mode (|||58551|)
then you will need to disable extended passive mode with epsv4 off. See
the above section The .netrc File for an example of how to make this
automatic.
Above it states:
epsv4 Toggle the use of the extended EPSV and EPRT commands on IPv4
connections; first try EPSV / EPRT, and then PASV / PORT.
This is enabled by default. If an extended command fails
then this option will be temporarily disabled for the dura-
tion of the current connection, or until epsv4 is executed
again.
You can use this setting either via .netrc or as an interactive command.
