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

| Disable the use of PORT with --ftp-pasv. Disable the attempt to use the EPRT |
| command instead of PORT by using --disable-eprt. EPRT is really PORT++. |
| |
| You can also append ":[start]-[end]\&" to the right of the address, to tell |
| curl what TCP port range to use. That means you specify a port range, from a |
| lower to a higher number. A single number works as well, but do note that it |
| increases the risk of failure since the port may not be available. |
