(PHP Extension) FTP through SSH Tunnel

Demonstrates how to FTP through an SSH tunnel.

The Chilkat SSH tunnel object is used to create a portable SSH tunnel w/ dynamic port forwarding on a background thread that the foreground thread can use for establishing connections through an SSH tunnel.

PHP Extension for Windows, Linux, MAC OS X,
Alpine Linux, Solaris, OpenBSD, FreeBSD,
and Linux armhf/aarch64

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

//  Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
//  by calling UnlockBundle.  It requires a Bundle unlock code.
$chilkatGlob = new CkGlobal();
$success = $chilkatGlob->UnlockBundle('Anything for 30-day trial.');
if ($success != true) {
    print $chilkatGlob->lastErrorText() . "\n";
    exit;
}

//  This example requires Chilkat version 9.5.0.50 or greater.
$tunnel = new CkSshTunnel();

$sshHostname = 'www.my-ssh-server.com';
$sshPort = 22;

//  Connect to an SSH server and establish the SSH tunnel:
$success = $tunnel->Connect($sshHostname,$sshPort);
if ($success != true) {
    print $tunnel->lastErrorText() . "\n";
    exit;
}

//  Authenticate with the SSH server via a login/password
//  or with a public key.
//  This example demonstrates SSH password authentication.
$success = $tunnel->AuthenticatePw('mySshLogin','mySshPassword');
if ($success != true) {
    print $tunnel->lastErrorText() . "\n";
    exit;
}

//  Indicate that the background SSH tunnel thread will behave as a SOCKS proxy server
//  with dynamic port forwarding:
$tunnel->put_DynamicPortForwarding(true);

//  We may optionally require that connecting clients authenticate with our SOCKS proxy server.
//  To do this, set an inbound username/password.  Any connecting clients would be required to
//  use SOCKS5 with the correct username/password.
//  If no inbound username/password is set, then our SOCKS proxy server will accept both
//  SOCKS4 and SOCKS5 unauthenticated connections.

$tunnel->put_InboundSocksUsername('chilkat123');
$tunnel->put_InboundSocksPassword('password123');

//  Start the listen/accept thread to begin accepting SOCKS proxy client connections.
//  Listen on port 1080.
$success = $tunnel->BeginAccepting(1080);
if ($success != true) {
    print $tunnel->lastErrorText() . "\n";
    exit;
}

//  Now that a background thread is running a SOCKS proxy server that forwards connections
//  through an SSH tunnel, it is possible to use any Chilkat implemented protocol that is SOCKS capable,
//  such as Socket, HTTP, POP3, SMTP, IMAP, FTP, etc.  The protocol may use SSL/TLS because the SSL/TLS
//  will be passed through the SSH tunnel to the end-destination.  Also, any number of simultaneous
//  connections may be routed through the SSH tunnel.

//  Let's do an FTP upload through the SSH tunnel.  Both the control and data connections
//  go through the tunnel.
$ftp = new CkFtp2();

$ftp->put_Hostname('ftp.someFtpServer.com');
$ftp->put_Username('****');
$ftp->put_Password('****');

//  Indicate that the FTP2 object is to use our portable SOCKS proxy/SSH tunnel running in our background thread.
$ftp->put_SocksHostname('localhost');
$ftp->put_SocksPort(1080);
$ftp->put_SocksVersion(5);
$ftp->put_SocksUsername('chilkat123');
$ftp->put_SocksPassword('password123');

//  Connect to the FTP server
$success = $ftp->ConnectOnly();
if ($success != true) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

//  Authenticate with the FTP server.
$success = $ftp->LoginAfterConnectOnly();
if ($success != true) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

//  Change to the remote directory where the file will be uploaded.
$success = $ftp->ChangeRemoteDir('junk');
if ($success != true) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

//  Upload a file.
$localPath = '/temp/hamlet.xml';
$remoteFilename = 'hamlet.xml';

$success = $ftp->PutFile($localPath,$remoteFilename);
if ($success != true) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

//  This closes the SSH channel within the SSH tunnel,
//  and thus closes the connection with the FTP server.
$success = $ftp->Disconnect();

print 'File Uploaded!' . "\n";

//  Stop the background listen/accept thread:
$waitForThreadExit = true;
$success = $tunnel->StopAccepting($waitForThreadExit);
if ($success != true) {
    print $tunnel->lastErrorText() . "\n";
    exit;
}

//  Close the SSH tunnel (would also kick any remaining connected clients).
$success = $tunnel->CloseTunnel($waitForThreadExit);
if ($success != true) {
    print $tunnel->lastErrorText() . "\n";
    exit;
