From: info from Bugzilla, text by Olegy <olegy at olegy.ru> Newsgroups: email Date: Mon, 15 Nov 2004 14:31:37 +0000 (UTC) Subject: Установка антивируса и спамфильтра для почтовой системы qmail Установка Антивирус+Спамфильтр для почтовой системы qmail (qmail+ucspi-tcp) OS FreeBSD Установка нужного программного обеспечения: ------------------------------------------- 1) Обновляем порты если, они вручную не обновляются. Рабочая конфигурация : amavisd-new-2.1.2 + clamav-0.80 стоит у меня на freebsd 4.9 2) cd /usr/ports/security/amavisd-new/ делаем make, если ругается на perl, идём в /usr/ports/lang/perl5.8 делаем make install если всё поставилось без вопросов, тогда идём в cd /work делаем файл use.perl запускным, после чего запускаем - ./use.perl port Теперь у нас есть perl линейки 5.8 и он анонсирован в системе как дефолтный. Идём опять в /usr/ports/security/amavisd-new/ И делаем : make после чего идём в папку cd /work/amavisd-new-2.1.2 и делаем следующее : patch <amavisd-new-qmqpqq.patch Далее : make install Это мы поставили приблуду которая свяжет нам спамфильтр и антивирус (поддерживает около 10-ти антивирусных систем, можно включить все сразу, "для параноиков" 8-))) ). 3) Ставим спамфильтр - cd /usr/ports/mail/p5-Mail-SpamAssassin/ make make install 4) Ставим антивирус cd /usr/ports/security/clamav/ make make install 5) Нам нужно пропатчить наш qmail, ищем папку с исходниками qmail-а, если таковой уже давно нет, тогда идём на http://www.opennet.ru/base/net/qmail_antispam.txt.html и качаем по ссылкам qmail и все нужные патчи к нему, плюс тот что нужен нам можно найти здесь - http://www.imladris.sk/howto/download/qmail-queue.patch Далее патчим qmail всеми патчами. Идём в каталог с qmail-ом, находим файл qmail-qmqpc.c и меняем в нем #define PORT_QMQP 628 на #define PORT_QMQP 10628 Устанавливаем qmail туда же где он уже стоит. Настройка программного обеспечения: ------------------------------------ 1) Идём туда где у нас лежит файл с адресами которым разрешен "открытый релей", у меня такой файл лежит в /etc называется tcp.smtp, в него нужно добавить строчку: 127.10.10.10:allow,RELAYCLIENT="",QMAILQUEUE="bin/qmail-queue.orig" Далее нужно создать файл tcp.smtp.amavis и сунуть в него следующее : 127.10.10.10:allow,RELAYCLIENT="",QMAILQUEUE="bin/qmail-queue.orig":deny А в файл ренегации базы добавить строчку : tcprules /etc/tcp.smtp.amavis.cdb /etc/tcp.smtp.amavis.tmp < /etc/tcp.smtp.amavis В файл запуска tcpserver-ов добавляем : tcpserver -x /etc/tcp.smtp.amavis.cdb -p -DRHl localhost -u 89 -g 83 127.10.10.10 10025 \ /var/qmail/bin/qmail-smtpd & В моем случае - -u 89 : это uid пользователя vpopmail -u 83 : это gid группы vchkpw 2) В папке /var/qmail/control создать файл qmqpservers и сунуть в него: 127.10.10.10 3) Нам нужен алиал ip на локальном интерфэйсе, для этого запускаем команду: ifconfig lo0 inet 127.10.10.10 netmask 255.255.255.255 alias И дописываем в /etc/rc.conf : ifconfig_lo0_alias0="inet 127.10.10.10 netmask 255.255.255.255" 4) Привожу свой конфигурационный файл от amavisd-new (в нём только нужно указать ваш дефолтный домен), лежит он /usr/local/etc/amavisd.conf:

5) Идём в папку /usr/local/etc/rc.d, нужно немного подредактировать запускные файлы amavisd.sh, clamav-clamd.sh и clamav-freshclam.sh, в них во всех нужно заскоментировать строчки : в amavisd.sh: amavisd_enable="YES" в clamav-clamd.sh: clamav_clamd_enable="YES" в clamav-freshclam.sh: clamav_freshclam_enable="YES" Теперь всё готово к запуску, НО, всё же ещё рано, нужно занести пользователя clamav в группу vscan, для этого идём в /etc и открываем файл group, дописываем clamav в группу vscan и должно получится что-то вроде : vscan:*:1002:clamav Теперь наверное всё. Идём в /usr/local/etc/rc.d и запускаем файлы amavisd.sh, clamav-clamd.sh и clamav-freshclam.sh. Смотри процессы ps ax, если всё запустилось нормально, в списке должны быть : 162 ?? Ss 0:10.66 amavisd (master) (perl) 190 ?? Ss 1:32.63 /usr/local/sbin/clamd 197 ?? Is 0:00.18 /usr/local/bin/freshclam -daemon 22326 ?? S 1:17.30 amavisd (ch331-avail) (perl) 22555 ?? S 1:15.20 amavisd (ch327-avail) (perl) 22668 ?? S 1:11.71 amavisd (ch329-avail) (perl) 22723 ?? S 1:09.37 amavisd (ch325-avail) (perl) 22742 ?? S 1:13.26 amavisd (ch325-avail) (perl) 22770 ?? S 1:13.80 amavisd (ch326-avail) (perl) 22803 ?? S 1:15.35 amavisd (ch324-avail) (perl) 22944 ?? R 1:09.06 amavisd (22944-323) (perl) 23023 ?? S 1:10.89 amavisd (ch320-avail) (perl) 23036 ?? S 1:12.03 amavisd (ch324-avail) (perl) Если всё это есть и amavisd запустился без ошибок, тогда нам остается на пару секунд зашатдаунить qmail для того чтобы сделать пару заключительных команд : cd /var/qmail/bin mv qmail-queue qmail-queue.orig ln -s qmail-qmqpc qmail-queue после чего запускаем qmail и наслаждаемся. Всю информацию по пойманным вирусам и спаму читать в /var/amavis/amavis.log

    "Далее нужно создать файл tcp.smtp.amavis и сунуть в него следующее :

    127.10.10.10:allow,RELAYCLIENT="",QMAILQUEUE="bin/qmail-queue.orig":deny

        А в файл ренегации базы добавить строчку :
    tcprules /etc/tcp.smtp.amavis.cdb /etc/tcp.smtp.amavis.tmp < /etc/tcp.smtp.amavis"

    У меня после запуска

    tcprules /etc/tcp.smtp.amavis.cdb /etc/tcp.smtp.amavis.tmp < /etc/tcp.smtp.amavis

    ругань:
    tcprules: fatal: unable to parse this line: 127.10.10.10:allow,RELAYCLIENT="",QMAILQUEUE="/bin/qmail-queue.orig":deny

    :(

    Вообще-то правильно будет

    127.10.10.10:allow,RELAYCLIENT="",QMAILQUEUE="bin/qmail-queue.orig"
    :deny

    в две строчки: разрешаем для 127.10.10.10 и запрещаем для всех остальных

    Если используете clamav будте осторожны с параметром ScanRAR т.к. сжатые файлы формата rar3 будут дропаться... Есть в инете статья как обойти эту неприятность http://mcmcc.bat.ru/clam_rar3.html

    Не работает это на Фре шестой.

    Вот это
    ============================
        Идём опять в /usr/ports/security/amavisd-new/
        И делаем :
    make
        после чего идём в папку cd /work/amavisd-new-2.1.2
        и делаем следующее :
    patch <amavisd-new-qmqpqq.patch
        Далее :
    make install
    =============================

    Даёт 0 эффекта. Нужно сначало удалить файл work/.build_done.amavisd-new-2.4.0,1._usr_local. Потом запустить make и make install.

    Но до этого не сложно догадаться. Что только делать с вот этой вот ошибкой:

    server2# ./amavisd.sh start
    Starting amavisd.
    In::QMQPqq code not available at /usr/local/sbin/amavisd line 9071.
    server2#

    На этом всё потухает.

    Quoute:
    =========================================
    5) Идём в папку /usr/local/etc/rc.d, нужно немного подредактировать запускные файлы
       amavisd.sh, clamav-clamd.sh и clamav-freshclam.sh, в них во всех нужно
       заскоментировать строчки :

        в amavisd.sh:
    amavisd_enable="YES"

        в clamav-clamd.sh:
    clamav_clamd_enable="YES"

        в clamav-freshclam.sh:
    clamav_freshclam_enable="YES"
    =======================================

    зачем такие извращения?
    может правильнее будет прость прописать в /etc/rc.conf

    amavisd_enable="YES"
    clamav_clamd_enable="YES"
    clamav_freshclam_enable="YES"
