CURLOPT_FTP_USE_EPRT(3) libcurl CURLOPT_FTP_USE_EPRT(3)
NAME
CURLOPT_FTP_USE_EPRT - use EPRT for FTP
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_EPRT, long enabled);
DESCRIPTION
Pass a long. If the value is 1, it tells curl to use the EPRT command
when doing active FTP downloads (which is enabled by CURLOPT_FTP-
PORT(3)). Using EPRT means that libcurl first attempts to use EPRT
before using PORT, but if you pass zero to this option, it avoids using
EPRT, only plain PORT.
The EPRT command is a slightly newer addition to the FTP protocol than
PORT and is the preferred command to use since it enables IPv6 to be
used. Very old FTP servers might not support it, which is why libcurl
has a fallback mechanism. Sometimes that fallback is not enough and
then this option might come handy.
If the server is an IPv6 host, this option has no effect as EPRT is
necessary then.
