- As reported in Mandrake's bug tracker bug 12285

  (http://qa.mandrakesoft.com/show_bug.cgi?id=12285), when connecting to an

  IPv6 host with FTP, --disable-epsv (or --disable-eprt) effectively disables

  the ability to transfer a file. Now, when connected to an FTP server with

  IPv6, these FTP commands can't be disabled even if asked to with the

  available libcurl options.

.SH NAME

curl_easy_setopt - set options for a curl easy handle

.SH SYNOPSIS

\fICURLOPT_FTPPORT\fP). Using EPRT means that it will first attempt to use

EPRT and then LPRT before using PORT, but if you pass FALSE (zero) to this

option, it will not try using EPRT or LPRT, only plain PORT. (Added in 7.10.5)

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

.IP CURLOPT_FTP_USE_EPSV

Pass a long. If the value is non-zero, it tells curl to use the EPSV command

when doing passive FTP downloads (which it always does by default). Using EPSV

means that it will first attempt to use EPSV before using PASV, but if you

pass FALSE (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.

.IP CURLOPT_FTP_CREATE_MISSING_DIRS

Pass a long. If the value is non-zero, curl will attempt to create any remote

directory that it fails to CWD into. CWD is the command that changes working
