1) Проблема: Не могу настроить автозапуск деманов flow tools (flow-capture и softflowd).
2) Исходные данне:
- freebsd использую меньше недели. До этого работал в дебиан. Хочу перейти на freebsd, система весьма симпатична.
- хост находица на вм машине. Является тестовой площаткой для разработки шлюза
- установил следующее: freebsd 8.2 + mpd5 (впн сервер) + ipf + ipnat - связка замечательно работает.
3) Решаемая задача: на внешнем интерфейсе (em0) собирать статистику по трафику.
И так. Решил ставить flow tools + iptraf. Реализация сенсора и хранилища flow tools на одном хосте.
Поставил из портов flow-capture и softflowd. Юзал ресурсы : http://xgu.ru/wiki/NetFlow http://subnets.ru/blog/?p=1632 http://vova-zms.blogspot.com/2009_04_01_archive.html .
Связка flow-capture и softflowd у меня замечательно стартует из командной строки с толкача так сказать в ручную путем:
router# /usr/local/bin/flow-capture -p /var/run/flow-capture.pid -n 287 -N 0 -w /var/netflow/ -S 5 0/0/8787
softflowd -i em0 -n 127.0.0.1:8787
начинает логии класть куда надо. Все замечательно. Проверял.
Но я столкнулся с проблемой когда логично захотел чтобы у меня стартовали деманы. В силу своих познаний и наития отконфигурировал /etc/rc.conf , но счастья нет.
В мануалах, которыми я пользовался, в одних написано что нужно какой то скрипт запуска редактировать, в других ничего не пишется толком. Инфа неоднозначная и еще не понят для каких версий ПО и ОС.
Прошу помочь настроить автозапуск деманов flow-capture и softflowd.
Ниже привожу конфиг(/etc/rc.conf ег оуже по всякому перевертел, всеравно не стартует автоматом) и скрипты(руками не трогал).

#
# Add the following line to /etc/rc.conf to enable flow-capture:
# flow_capture_enable (bool): Set it to "YES" to enable flow-capture daemon.
# Set to "NO" by default.
# flow_capture_datadir (str): Base flow data directory.
# Default is "/var/db/flows"
# flow_capture_localip (str): IP address to bind to
# Default to "0.0.0.0"
# flow_capture_remoteip (str): IP address to accept flows from
# Default to "0.0.0.0" or all IPs
# flow_capture_port (int): Port to accept flow data on
# Default is "8787"
# flow_capture_flags (str): Custom additional arguments to be passed
# to flow-collector (default "-E 128M").
# flow_capture_profiles (str): A list of configuration profiles to enable.
# This allows you to run several instances of
# flow-capture with different parameters.
# Consider the following example:
# flow_capture_enable="YES"
# flow_capture_localip="85.172.168.9"
# flow_capture_profiles="r1 r2"
# flow_capture_r1_datadir="/var/db/flows/r1"
# flow_capture_r1_port="4444"
# flow_capture_r1_flags="-E20G -n287 -N-2"
# flow_capture_r2_datadir="/var/db/flows/r2"
# flow_capture_r2_port="4445"
# flow_capture_r2_flags="-E5G -n287 -N-2"
#
# This will run two instances of the flow-capture
# with parameters taken from appropriate
# flow_capture_PROFILENAME_xxx variables. For
# unspecified parameters flow_capture_xxx
# varialbes will be used.
