.TH CURLOPT_FTPPORT 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_FTPPORT \- make FTP transfer active
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTPPORT, char *spec);
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a null-terminated string as parameter. It specifies that the
|
|
FTP transfer will be made actively and the given string will be used to get
|
|
the IP address to use for the FTP PORT instruction.
|
|
|
|
The PORT instruction tells the remote server to connect to our specified IP
|
|
address. The string may be a plain IP address, a host name, a network
|
|
interface name (under Unix) or just a '-' symbol to let the library use your
|
|
system's default IP address. Default FTP operations are passive, and thus
|
|
won't use PORT.
|
|
|
|
The address can be followed by a ':' to specify a port, optionally followed by
|
|
a '-' to specify a port range. If the port specified is 0, the operating
|
|
system will pick a free port. If a range is provided and all ports in the
|
|
range are not available, libcurl will report CURLE_FTP_PORT_FAILED for the
|
|
handle. Invalid port/range settings are ignored. IPv6 addresses followed by
|
|
a port or portrange have to be in brackets. IPv6 addresses without port/range
|
|
specifier can be in brackets.
|
|
|
|
Examples with specified ports:
|
|
|
|
.nf
|
|
eth0:0
|
|
192.168.1.2:32000-33000
|
|
curl.se:32123
|
|
[::1]:1234-4567
|
|
.fi
|
|
|
|
You disable PORT again and go back to using the passive version by setting
|
|
this option to NULL.
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
|
|
