Не удается пропинговать сервер Ubuntu после перезагрузки. Где искать возможные проблемы?
После перезапуска сервера Ubuntu я не могу пропинговать его. Мой хостинг (Herzner) позволяет загружать сервер с аварийно-спасательной системой, поэтому я могу получить доступ к файловой системе и попытаться ее исправить.
Вопрос в том, где искать проблемы?
Я проверил свой boot.log, и все выглядит нормально:
