Друзья.
Есть сервер под управлением Debian.
Периодически появляется проблема связанная с тем что с
одного айпи начинает валится уйма запросов к серверу +
из-за этого вырастает LA .
Например:
cat production.log | grep 178.95.42.226

В настройках nginx поставил лимит
limit_zone http $binary_remote_addr 1m;
limit_conn http 10;
При тесте Siege - nginx успешно дропает соединения больше 10 в единый момент времени.
В моем же случае такое условие не совпадает.
Можно ли как сделать так - если с одного айпи в течении минуты есть больше 30 обращений к серверу - то заворачивать злодея на страничку - заглушку?
Или как с таким бороться?
