CURLOPT_FTP_SKIP_PASV_IP
Section: curl_easy_setopt options (3) Updated: May 05, 2017 Index
Return to Main Contents
NAME
CURLOPT_FTP_SKIP_PASV_IP - ignore the IP address in the PASV response
SYNOPSIS
#include < curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_SKIP_PASV_IP, long skip);
DESCRIPTION
Pass a long. If skip is set to 1, it instructs libcurl to not use the IP
address the server suggests in its 227-response to libcurl's PASV command when
libcurl connects the data connection. Instead libcurl will re-use the same IP
address it already uses for the control connection. But it will use the port
number from the 227-response.
This option thus allows libcurl to work around broken server installations
that due to NATs, firewalls or incompetence report the wrong IP address back.
This option has no effect if PORT, EPRT or EPSV is used instead of PASV.
DEFAULT
0
