Neden bir SSH bağlantısı kullanmak değil mi? Soyut komutları uzak, giriş / çıkış yönlendirme ve tam denetime sahip olabilir.
Sen karşılaşılmasına kadar az haklara sahip saf, temiz kabuğu birisi sağlamak ve kabuk açmak için) (şifre sadece SSH2 :: Connect ile birlikte POST'ed sağlayabilirsiniz.
I created a nice class to work with the php SSH2 extension, maybe it helps you;
(and it also does secure file transfers)

Kullanımı örnek:
$settings = Settings::Load()->Get("SecureServer");
$ssh = new SSH2($settings['host']);
if( $ssh->connect($settings['username'], $settings['password']))
{
echo $ssh->exec("ls -la ".$settings['path'], false, true);
flush();
}
