Поделитесь лучшими практиками по сборке облака. Есть 4 физических сервера dell r820 и r620 по 2 каждого.

Всем доброго дня! Установил SVN сервер с апач на убунту. Подскажите как в SVN добавить старый репозиторий.Он лежит на этом же сервере в самба директории.

Всем привет! Помогите с задачкой: необходимо написать bash скрипт который осуществляет поиск количества попыток взлома по протоколу ssh с каждого ip и блокировку последнего с помощью iptables, если количество попыток превысило 10. В данном случае используйте регулярные выражения для поиска ip, отсортируйте результат по количеству попыток взлома для вывода результата. Пример файла журнала:
