Ошибок почти нет.
В чем может быть причина?
И еще в догонку один вопрос.
Можно ли установить в PPP на CISCO схему компрессии типа BSD-Compress
или Deflate? Что бы можно было компрессировать данные идущие через
канал средствами PPP.
И что означают :
compress predictor
compress stac
stac - вроде FreeBSD его не понимает.
predictor - вроде реакции никакой (при прокачке
текстового файла не видно компрессии).
Что посоветуете почитать/посмотреть?
