<?php

$success = 0;

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

$ssh = new COM("Chilkat.Ssh");

// To get the authentication methods offered by an SSH server, we first connect.
$success = $ssh->Connect('example.com',22);
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Next, we call GetAuthMethods to receive a comma separated list of authentication methods
$authMethods = $ssh->getAuthMethods();
if ($ssh->LastMethodSuccess != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// For example: publickey,password,keyboard-interactive
print 'Authentication methods suported by this serve: ' . $authMethods . "\n";

// IMPORTANT:
// Getting the authentication methods will intentionally disconnect from the server.
// We'll need to re-connect, etc. to continue..

// For example..
$success = $ssh->Connect('example.com',22);
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

$success = $ssh->AuthenticatePw('myLogin','myPassword');
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

print 'SSH Authentication successful.' . "\n";

// ...

$ssh->Disconnect();
