CURLOPT_FTP_USE_EPSV(3)             libcurl            CURLOPT_FTP_USE_EPSV(3)


NAME

       CURLOPT_FTP_USE_EPSV - use EPSV for FTP


SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_EPSV, long epsv);


DESCRIPTION

       Pass epsv as a long. If the value is 1, it tells curl to use the EPSV
       command when doing passive FTP downloads (which it does by default).
       Using EPSV means that it will first attempt to use EPSV before using
       PASV, but if you pass zero to this option, it will not try using EPSV,
       only plain PASV.

       If the server is an IPv6 host, this option will have no effect as of
       7.12.3.


DEFAULT

       1


PROTOCOLS

       FTP


EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/old-server/file.txt");

         /* let's shut off this modern feature */
         curl_easy_setopt(curl, CURLOPT_FTP_USE_EPSV, 0L);

         ret = curl_easy_perform(curl);

         curl_easy_cleanup(curl);
       }


AVAILABILITY

       Along with FTP


RETURN VALUE

       Returns CURLE_OK if FTP is supported, and CURLE_UNKNOWN_OPTION if not.
