See more SSH Examples

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

This example requires Chilkat v9.5.0.78 or greater.

Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    boolean success = false;

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

    CkSsh 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) {
        Log.i(TAG, ssh.lastErrorText());
        return;
        }

    // Next, we call GetAuthMethods to receive a comma separated list of authentication methods
    String authMethods = ssh.getAuthMethods();
    if (ssh.get_LastMethodSuccess() != true) {
        Log.i(TAG, ssh.lastErrorText());
        return;
        }

    // For example: publickey,password,keyboard-interactive
    Log.i(TAG, "Authentication methods suported by this serve: " + authMethods);

    // 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) {
        Log.i(TAG, ssh.lastErrorText());
        return;
        }

    success = ssh.AuthenticatePw("myLogin","myPassword");
    if (success != true) {
        Log.i(TAG, ssh.lastErrorText());
        return;
        }

    Log.i(TAG, "SSH Authentication successful.");

    // ...

    ssh.Disconnect();

  }

      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
