13 Reverses the default initiator/listener roles when connecting with FTP. This
14 option makes curl use active mode. curl then tells the server to connect back
15 to the client's specified address and port, while passive mode asks the server
16 to setup an IP address and port for it to connect to. <address> should be one
17 of:
18 .RS
19 .IP interface
20 e.g. "eth0" to specify which interface's IP address you want to use (Unix only)
21 .IP "IP address"
22 e.g. "192.168.10.1" to specify the exact IP address
23 .IP "host name"
24 e.g. "my.host.domain" to specify the machine
25 .IP "-"
26 make curl pick the same IP address that is already used for the control
27 connection

30 If this option is used several times, the last one will be used. Disable the
31 use of PORT with --ftp-pasv. Disable the attempt to use the EPRT command
32 instead of PORT by using --disable-eprt. EPRT is really PORT++.
33 
34 You can also append \&":[start]-[end]\&" to the right of the address, to tell
35 curl what TCP port range to use. That means you specify a port range, from a
36 lower to a higher number. A single number works as well, but do note that it
37 increases the risk of failure since the port may not be available.
