Ssh2Transport

php ssh2 wrapper lib

Usage

This lib is designed to force safe and sane ssh connection use.

The ssh2 connection resource cannot be accessed until it has been successfully verified and authenticated (in THAT order).

use Ssh2Transport\Connection;
use Ssh2Transport\Exception\ConnectionFingerprintNotMatchException;

$connection = new Connection('example.com');

//
// be safe: verify remote server fingerprint
//   (the library is designed to "force" this step)
// 
try {
  $verifiedConnection = $connection->verify('6F89C2F0A719B30CC38ABDF90755F2E4');
} catch (ConnectionFingerprintNotMatchException $e) {
  echo "got an unexpected fingerprint: ".$e->getFingerprint();
  throw $e;
}

//
// one more step: need to authenticate
//
use Ssh2Transport\Authenticator\PasswordAuthenticator;
$authenticatedConnection = $verifiedConnection->authenticate(new PasswordAuthenticator('my-username','my-password'));

//
// finally, you may safely enjoy the authenticated ssh connection with native ssh_* functions as desired
//
$session = $authenticatedConnection->getSession();
ssh2_exec($session,"some command");
