If FTPS is enabled, data channel encryption is negotiated immediately after opening the data channel. IIS FTP server and ProFTPD only allow TLS negotiation after NLST command has been issued and data ready to be transmitted. As it is, FTPS opendir() and scandir() against IIS or ProFTPD effectively hang until the negotiation times out. Test script: --------------- <?php foreach (scandir('ftps://example.com/') as $fn) { print $fn ."\n"; } Expected result: ---------------- file1 file2 file3 Actual result: -------------- Warning: scandir(): SSL: Handshake timed out in test.php on line 2 Warning: scandir(ftps://example.com/): failed to open dir: Unable to activate SSL mode in test.php on line 2 Warning: scandir(): (errno 0): Success in test.php on line 2 Warning: Invalid argument supplied for foreach() in test.php on line 2 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72764&edit=1
