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.

Node.js

NODEJS_PRELUDE

function chilkatExample() {

    var success = false;

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

    var ssh = new chilkat.Ssh();

    //  To get the authentication methods offered by an SSH server, we first connect.
    success = ssh.Connect("example.com",22);
    if (success !== true) {
        console.log(ssh.LastErrorText);
        return;
    }

    //  Next, we call GetAuthMethods to receive a comma separated list of authentication methods
    var authMethods = ssh.GetAuthMethods();
    if (ssh.LastMethodSuccess !== true) {
        console.log(ssh.LastErrorText);
        return;
    }

    //  For example: publickey,password,keyboard-interactive
    console.log("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) {
        console.log(ssh.LastErrorText);
        return;
    }

    success = ssh.AuthenticatePw("myLogin","myPassword");
    if (success !== true) {
        console.log(ssh.LastErrorText);
        return;
    }

    console.log("SSH Authentication successful.");

    //  ...

    ssh.Disconnect();
