Прошу помощи в диагностике и решении появившейся проблемы с VPN. До недавнего времени всё работало как часы, но потом появились проблемы. Причина мне непонятна, так как настройки соединения я не менял.

У провайдера VPN, запущенный на Windows. Имеем домашний компьютер: Linux debian 2.6.8-2-386 #1 Thu May 19 17:40:50 JST 2005 i686 GNU/Linux

поднят pppd с опциями

Нормально устанавливается соединение, прописывается маршрут в таблицу

Спустя 3-4 мин соединение падает, потом устанавливается вновь. В syslog имеем такие вот сообщения:

В чём проблема? Помогите, пожалуйста, разобраться!

Установлен ASPLinux 9 версии. Пытаюсь установить VMware с диска, который входит в состав дистрибутива. При запуске конфигурационного скрипта, при указании местонахождения файлов заголовков, возникает конфликт с версией запущенного ядра:

The directory of kernel headers (version 2.4.20) does not match your running kernel (version 2.4.20-9asp). Even if the module were to compile successifully, it it would not load into running kernel. What is the location of the directory of C header files that match your running kernel?

Команда uname -a выдаёт: Linux 2.4.20-9asp i686 athlon i386 GNU/Linux

Других файлов заголовков в системе не обнаружено. Как разрешить конфликт? Заранее благодарен за помощь.

Установлен ASPLinux 9.2. (Ядро 2.4.20-9.asp). По USB подключаем цифровую камеру Canon A70. Камера не опознаётся.

Детали. В ядре включены опции:

General setup ---> [*] Support for hot-pluggable devices [*] Probe all LUNs on each SCSI device

Device Drivers ---> USB support <*> Support for Host-side USB

SCSI support ---> <*> SCSI support <*> SCSI disk support <*> SCSI generic support

USB support ---> <*> Support for USB <*> Preliminary USB device filesystem <*> UHCI (Intel PIIX4, VIA, ...) support <*> USB Mass Storage support

По команде dmesg имеем:

Вводим команду: mount -t vfat /dev/sda1 /mnt/camera Получаем: mount: /dev/sda1 is not valid block device

Почему невозможно обратиться к устройству sda1 несмотря на включение драйверов SCSI в ядро? Подскажите в чём дело и что делать? Заранее благодарен.
