In both cases pppd (with the persist option) attempts to reconnect immediately, without waiting for the specified holdoff time.

Зедержки нет, как и раньше, но теперь при нажатии ^C выдаётся громадное количество сообщений "Terminating on signal 2.", и в конечном итоге Segmentation fault. 14889 4 voins 2004-06-08 16:20:10 +0400 зацикливаниие сигналов я победил. c holdoff всё хуже. значение holdoff принудительно сбрасывается в 0 уже после разбора опций из-за ошибки в коде. Я могу поставить хак, который будет спасать holdoff. Подозреваю, что там спрятано ещё много таких же граблей. Для нормального исправления этой ошибки потребуется изменение значительного куска кода pppd. Влезать в это очень не хочется. 14890 5 voins 2004-06-08 16:39:09 +0400 fixed in ppp-2.4.2-alt2
