Скрипт для конфигурирования устройств с использованием telnet

Иногда приходится применять большое количество команд на коммутаторах , автоматизация данного процесса значительно облегчает жизнь.

Данный скрипт не претендует на оптимальность, но зато полностью логирует все действия производимые на устройстве.

В скрипте предусмотрен ввод логина и пароля для авторизации на устройстве - легко меняется, например можно сразу указать логин и пароль.

В папке со скриптом должен находится файл с командами и файл с IP адресами устройств.

В результате в директории где выполняется скрипт будет создана папка с логами. В папке будут логи под каждое устройство и общий лог.
