Доброе время суток уважаемые Гуру. Появилась проблема на серверах доступа под управлением FreeBSD 7.0 и 7.1 происходит постепенная или рывками утечка оперативной памяти после чего у него отказывает сетевая подсистема, т.е. полностью перестает работать сеть. Бывает это на разных сегментных серверах, т.е. может глючить по 2 раза в сутки целую неделю а потом простоять а аптайме не менее 3х месяцев и так может случится с любым из сегментных маршрутизаторов. Down Up интерфейса не лечит, лечит только ребут системы. Подставил костыль, скрипт пингует раз в минуту стабильный сервер если пинга нет, то скрипт перезагружает сервер ибо в противном случае приходилось дергать вручную. Данные сервера выполняют следующий функционал:
1. доступ в сеть абонентов при помощи VLAN;
2. доступ абонентов в сеть при помощи РРРоЕ на базе mpd5.1 до 200 сессий, авторизация происходит статически из файла mpd.secret т.к. Radius-сервер находится далеко;
3. автоматическая блокировка абонентов-должников при помощи ipfw, т.е. на каждого абонента для его статического IP-адреса на вот таком примере:
deny ip from 10.10.57.185 to any
deny ip from any to 10.10.57.185
данные правила динамически выгружает биллинг на сервер.
4. статическая маршрутизация между серверами доступа около 120 маршрутов и дефолт роут смотрящий на пограничный маршрутизатор, трафик не шейпируем.
5. прокачка Интернет и локального межсегментного трафика.
В сегментную сеть смотрит 2 гигабитных интерфейса а в межсегментную сеть один гигабитный интерфейс. Коммутируемое оборудование используем D-Link DGS-3426. 5 коммутаторов DGS-3426 образуют кольцо от них уже идут ответвления. На кольцевых коммутаторах настроен RSTP который отлично работает.
