-  Этот архив содержит набор CGI cкриптов и программ для получения 
-статистики работы пользователей прокси сервера "3proxy", посредством анализа
-лога расположенного в ODBC источнике(базе), через Web интерфейс.                      
-
-stat.awk - основной CGI скрипт (Для его испольнения под Win9X/2000 необходима 
-           программа awk.exe ,в linux/freebsd она как правило входит в сиситему
-           по умолчанию).    
-isqlodbc - программа для выполнения SQL запросов к базам ODBC 
-           (вызывается из stat.awk). компилируется gcc и работает как в 
-           win9X/2000 так и в linux/freebsd. (Так же может 
-           использоваться независимо от stat.awk как отдельная 
-           программа..)
-log.sql  - SQL скрипт создания базы для лога сервера.           
-awk.exe  - awk интерпретатор  под Win9X/2000.  
-
-                        Настройка скриптов статистики .
-
-Для работы вам потребуется:
-1) любой http сервер подерживающий CGI
-2) odbc менеджер (под win32 ) или iodbc менеджер (под unix)
-   любая база данных например : sqlite, mysql, postgress или любые другие 
-   имеющие ODBC драйвера.(Как настраивать iODBC под linux/freebsd смотрите в
-   файле iodbc.txt в  каталоге /doc/ru архива 3proxy.)
-
- Шаг настройки N1:
-Создаем базу данных и DSN для хранения лога. ( в нашем случае DSN будет 
-называться "sqlite".) далее выполняя скрипт log.sql создаем необходимые 
-таблицы и индексы:
-
-isqlodbc sqlite < log.sql
-
- Шаг настройки N2:
-Устанавливаем DSN и формат таблицы с логом в файле 3proxy.cfg следующего вида:
------------
-# create table log (
-#    ldate date,
-#    ltime time,
-#    username char (30),
-#    userip char (16),
-#    bytein integer (10),
-#    byteout integer (10),
-#    service char (8),
-#    host char(255),
-#    hostport integer (10),
-#    url char (255)
-#   );
-
-log &sqlite
-logformat "Linsert into log values ('%Y-%m-%d','%H:%M:%S','%U','%C','%I','%O','%N','%n','%r','%T');"
------------
-
- Шаг настройки N3:
-Копируем файлы isqlodbc и stat.awk в каталог с CGI скриптами http сервера 
-и меняем в stat.awk путь вызова и DSN на свои значения , например:
-isql="./isqlodbc.exe sqlite " 
-
- Шаг настройки N4:
-Пробуем вызвать скрипт из web браузера , например 
-
-http://localhost/cgi/stat.awk?
