Проверка сети

[Cxms]

Какой командой быстро (1-3сек.) и надежно проверять доступность интернета?
Если пингом то на какой лучше сервер, с какими опциями?

сервер например 8.8.8.8

symon2014,
Ман устарел, опции другие.

Проверяю так:
ping -q -c 3 ya.ru
норм?

[symon2014]

Думаю да, без опций параметры такие же.
