Multiple Hop SSH to SFTP

See more SFTP Examples

Demonstrates how to SFTP through an intermediate SSH server (multiple hop). The scheme looks like this:

Application => ServerSSH1 => ServerSFtp

The ConnectThroughSsh method is added in Chilkat version 9.5.0.55 to accomplish this task.

Chilkat2 PHP

<?php

use Chilkat2\SFtp;
use Chilkat2\Ssh;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$ssh1 = new Ssh();

// Hostname may be an IP address or domain name:
$hostname = '192.168.1.111';
$port = 22;

// Connect directly to the 1st SSH server:
try {
    $ssh1->Connect($hostname, $port);

    // Authenticate using login/password:
    $ssh1->AuthenticatePw('myLogin', 'myPassword');

    // Connect through the 1st SSH connection to reach a 2nd SSH server (for SFTP)
    // Note: Any number of connections may be simultaneously tunneled through a single
    // existing SSH connection.
    $sftp = new SFtp();

    // Connect to some SSH/SFTP server through ssh1.
    $sftp->ConnectThroughSsh($ssh1, 'sftp.someremoteserver.com', 22);

    // Authenticate with the SFTP server.
    $sftp->AuthenticatePw('myLogin', 'myPassword');

    // After authenticating, the SFTP subsystem must be initialized:
    $sftp->InitializeSftp();

    // Upload from the local file to the SSH server.
    // Important -- the remote filepath is the 1st argument,
    // the local filepath is the 2nd argument;
    $remoteFilePath = 'hamlet.xml';
    $localFilePath = 'c:/temp/hamlet.xml';

    $sftp->UploadFileByName($remoteFilePath, $localFilePath);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo "Success.\n";

// Close the connection with the SFTP server.(This closes the the tunnel through ssh1.)
// The connection with ssh1 is still alive, and may be used for more connections.
$sftp->Disconnect();

// ...
// ...
// ...

$ssh1->Disconnect();
