Скрипт для настройки сети openwrt

[zepete]

Я создал скрипт для настройки сети tl-mr3020 для случая, когда интернет он получает из wifi.
Он может пригодится, если этот маршрутизатор планируется использовать как консольный компьютер подключенный к интернету.
Он запрашивает только номер доступной точки доступа и ее пароль, а имя точки доступа он ищет сам.

#********************************************************************************
#* скрипт для настройки сети openwrt в качестве приемника интернета из wifi     *
#* достоинства:                                                                 *
#*  - настраивает eth на адрес 192.168.0.254, а если сеть 192.168.0.0/24 занята *
#*    wifi, то настраивает на сеть 192.168.1.254                                *
#*  - настраивает opkg на ftp://<сеть eth>.200/packages                         *
#*  - умеет определять мена доступных точк доступа                              *
#*  - если доступна только одна SSID, то выбирает ее автоматом                  *
#*  - настраивает синхронизацию времени                                         *
