- generate AVAILABILITY manpage sections automatically - for consistent wording - allows us to double-check against other documumentation (symbols-in-versions etc) - enables proper automation/scripting based on this data - lots of them were wrong or missing in the manpages - several of them repeated (sometimes mismatching) backend support info Add test 1488 to verify "added-in" version numbers against symbols-in-versions.

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 reuses the same IP address it already uses for the control connection. It still uses the port number from the 227-response.
This option allows libcurl to work around broken server installations or funny network setups that due to NATs, firewalls or incompetence report the wrong IP address. Setting this option also reduces the risk for various sorts of client abuse by malicious servers.
This option has no effect if PORT, EPRT or EPSV is used instead of PASV.
DEFAULT
1 since 7.74.0, was 0 before then.
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/file.txt");
/* please ignore the IP in the PASV response */
curl_easy_setopt(curl, CURLOPT_FTP_SKIP_PASV_IP, 1L);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
