Добрый вечер.
Не подскажите, в чем может быть дело? Есть выделенка на Тайнетах.
Асинк. 38400. С одной стороны циска, с другой - linux redhat 6.0. Пинг
удаленного конца (с любой стороны) показывает 540ms, что для 38400
достаточно много, на мой взгляд. Дропов нет. Чтобы это могло быть?
# ping -sn 195.133.230.238
