SFTP connection in PHP (not via ssh)

after creating a small library to send and receive files via SFTP using ssh2_sftp method I've found that the server which I have to connect to has ssh connection disabled and I can only connect through SFTP.

The server connection works well under the command line using sftp command, but ssh sends me a "This service allows sftp connections only."

So as ssh2_sftp needs a previous ssh connection in order to work, I don't know which library or how to do things in order to connect to a SFTP server with SFTP authentication.

Does phpseclib use a different authentication approach than ssh2_ftp?

Any ideas? Thanks.

99% of keyboard-interactive authentications just prompt for a password. phpseclib, a pure PHP SFTP implementation, tries submitting the password via keyboard-interactive if password authentication fails. Example of how to use it:

<?php
include('Net/SFTP.php');

$sftp = new Net_SFTP('www.domain.tld');
if (!$sftp->login('username', 'password')) {
    exit('Login Failed');
}

// outputs the contents of filename.remote to the screen
echo $sftp->get('filename.remote');
?>

Yes, you're completely right @arkascha... after a little research I found the reason.

When I was testing my code against my own server, it worked, and against the other server it was failing so I thought it was because ssh shell connection was disabled.

After asking both servers for the allowed auth methods (using ssh2_auth_none), I got what was wrong:

My server:

[0] => publickey

[1] => password

The other server (the one that was failing):

[0] => publickey

[1] => gssapi-keyex

[2] => gssapi-with-mic

[3] => keyboard-interactive

as it doesn't allow password, it is failing. That's it...

I apologize for making you waste your time...Thanks a lot
