Demonstrates how to get the authentication methods of an SSH server.

This example requires Chilkat v9.5.0.78 or greater.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?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");

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

$ssh = new CkSsh();

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

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

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

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

// ...

$ssh->Disconnect();
