Get SSH Server Authentication Methods

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.

Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    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) {
        System.out.println(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) {
        System.out.println(ssh.lastErrorText());
        return;
        }

    // For example: publickey,password,keyboard-interactive
    System.out.println("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) {
        System.out.println(ssh.lastErrorText());
        return;
        }

    success = ssh.AuthenticatePw("myLogin","myPassword");
    if (success != true) {
        System.out.println(ssh.lastErrorText());
        return;
        }

    System.out.println("SSH Authentication successful.");

    // ...

    ssh.Disconnect();
  }
}
