README

PHP library that provides an object-oriented wrapper to connect to SSH and run shell commands with the php ssh2 extension.

Requirements

• PHP version 5.3+
• SSH2 extension.
• composer.

Install with composer

The best way to add the library to your project is using composer.

composer require faraweilyas/sshbunny

or

Clone this repo

git clone https://github.com/faraweilyas/sshbunny.git

Configuration

SSHBunny constructor takes four parameters and they all have default values $method='local', $authType=NULL, $host=NULL, $port=22, $username=NULL

• $method can be set to local or remote, local will execute commands on your own shell without internet connection while remote executes commands on the remote server that you connect to based on your configuration.
• $authType can be set to KEY, PASSWORD or KEY_PASSWORD, KEY and KEY_PASSWORD uses ssh2_auth_pubkey_file the difference is when you set $authType='KEY_PASSWORD' ssh2_auth_pubkey_file takes the last parameter of password which will now be required and PASSWORD uses ssh2_auth_password.
• $port should be set to your server port if your are connecting to a remote server.
• $username should be set to your server username.

if your are setting connection method to $method='remote' and $authType = KEY || KEY_PASSWORD that means you will need to set your public & private key file which you can do with the setters SSHBunny has $sshBunny->setKeys('public_key.pub', 'private_key') before initialization.

Basic usage

This is just going to run locally since connection method is set to local

<?php

use SSHBunny\SSHBunny;

require_once 'vendor/autoload.php';

// ->getData() will return output of command executed while ->getData(TRUE) will dispay the output
$sshBunny = (new SSHBunny('local'))
    ->initialize()
    ->exec("echo 'Hello World'")
    ->getData(TRUE);

This is going connect to a remote server since connection method is set to remote and authentication type is set to KEY

<?php

use SSHBunny\SSHBunny;

require_once 'vendor/autoload.php';

defined('TEST_HOST')    ? NULL : define('TEST_HOST',    "138.222.15.1");
defined('PORT')         ? NULL : define('PORT',         "22");
defined('USERNAME')     ? NULL : define('USERNAME',     "ubuntu");
defined('PUBLIC_KEY')   ? NULL : define('PUBLIC_KEY',   'id_ssl.pub');
defined('PRIVATE_KEY')  ? NULL : define('PRIVATE_KEY',  'id_ssl');

$sshBunny = (new SSHBunny('remote', 'KEY', HOST, PORT, USERNAME))
    ->setKeys(PUBLIC_KEY, PRIVATE_KEY)
    ->initialize()
    ->exec("echo 'Hello World'")
    ->getData(TRUE);

Command execution can take multiple commands or you can chain on the exec method with another exec method

$sshBunny = (new SSHBunny('remote', 'KEY', HOST, PORT, USERNAME))
    ->setKeys(PUBLIC_KEY, PRIVATE_KEY)
    ->initialize()
    // Multiple commands
    ->exec("echo 'Hello World'", "cd /var/www/html")
    // Method chaining
    ->exec("ls -la")
    ->getData(TRUE);

Available methods

• Executed command output

// Will return the result of executed command output
$sshBunny
    ->exec("ls -la")
    ->getData();
// Will display the result of executed command output
$sshBunny
    ->exec("ls -la")
    ->getData(TRUE);

• Clear stored executed command output

// Will clear the first executed command output and return the next executed command output
$sshBunny
    ->exec("ls -la")
    ->clearData()
    ->exec("whoami")
    ->getData(TRUE);

• Disconnect server connection

// Will run the commands provided and display the result then disconnect from the server
$sshBunny
    ->exec("ls -la", "whoami")
    ->getData(TRUE)
    ->disconnect();
