is it possible to connect to an ftp-tls server (port 21) through the php cURL functions?
my first attempt is this:
$res = curl_init("ftp://example.com");
curl_setopt($res,CURLOPT_FTP_SSL,CURLFTPSSL_ALL);
curl_setopt($res,CURLOPT_PORT,21);
curl_setopt($res,CURLOPT_SSL_VERIFYPEER,FALSE);
curl_setopt($res,CURLOPT_SSL_VERIFYHOST,FALSE);
//curl_setopt($res,CURLOPT_SSLVERSION,CURL_SSLVERSION_TLSv1);
//curl_setopt($res,CURLOPT_FTPSSLAUTH,CURLFTPAUTH_TLS);
curl_setopt($res,CURLOPT_FTP_USE_EPSV,TRUE);
curl_setopt($res,CURLOPT_USERPWD,"user:**********");
curl_setopt($res,CURLOPT_INFILE,$file);
if (curl_exec($res))
{
echo "<br />connect succeeded<br />";
}
else echo "connect failed: ".curl_error($res)."<br />";
print_r(curl_getinfo($res));
curl_close($res);The server itself is set up properly (it seems): This is a readout of a successful connection using CoreFTP:
USER user
331 User name okay, need password for user.
PASS **********
230 User logged in, proceed.
SYST
215 UNIX Type: Apache FTP Server
Keep alive off...
PWD
257 "/" is current directory.
PBSZ 0
200 Command PBSZ okay.
PROT C
200 Command PROT okay.
PASV
