Subject: Несколько доменов SAMBA на одной машине FreeBSD
Несколько доменов SAMBA на одной машине freebsd - это реальность.
Не один раз читал, что "нельзя на одной freebsd машине запустить
несколько PDC под samba". Так вот плюньте в глаз тому, кто это сказал.
Для этого необходимо скомпилировать несколько копий пакета в РАЗНЫЕ
пути. Естественно необходимо указать и разное расположение всех файлов
(db, lock, pid files, smbpasswd e.t.c.) и конечно же разные smb.conf
В системе:
1. заводим несколько алиасов на сетевом интерфейсе. Несколько копий
самбы не могут использовать один и тот же адрес, но разные алиасы -
за милую душу.
В конфиг файлах:
1. для каждого домена пишем свои (уникальные) interfaces
2. пишем allowed hosts (не себя любимого ессно пускаем везде).
3. bind interfaces only = yes
4. само собой - разные имена домена и нетбиос неймы.
5. нежелательно чтобы в разных копиях самбы осуществлялся
одновременный доступ на ридрайт к тем же файлам (нет уверенности что
в этом случае файл локи правильно сработают)
Единственное ограничение - не получается (пока) запустить несколько
независимых WINS серверов (nmbd). Поэтому в одном домене пишем wins
support = yes, а в остальных wins server=(ip первого домена) и wins
proxy=yes. В этой конфигурации первый винс помнит все файлы, а остальные
отвечают на запросы "своих" компов. И все нормально видится (на компах
2-го, 3-го и т.д. доменов указываем винс своей сети).
Неудобство - стартовать-стопить процесс надо непосредственно из
/usr/local/etc/rc.d , а утилитами пользоваться из /usr/local/samba_nomer_1/bin (то есть из
того пути, где лежат бины нужного проекта)
Для удобства построения накидал пару скриптов:
Конфигуратор.
Строим так:
1. идем туда, где у нас раскручен пакет. Например у меня :
cd /usr/soft/samba-3.0.21b
2. Выполняем:
cd source
3. помещаем сюда все 3 файла приведенных тут (mk , samba.sh.sample, smb.conf.default)

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba,
# read the Samba-HOWTO-Collection. This may be obtained from:
# http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the
# Samba-Guide which is generated daily and can be downloaded from:
# http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.

#======================= Global Settings =====================================
[global]
# server string is the equivalent of the NT Description field

# Security mode. Defines in which mode Samba will operate. Possible
# values are share, user, server, domain and ads. Most people will want
# user level security. See the Samba-HOWTO-Collection for details.
security = user
# This option is important for security. It allows you to restrict
# connections to machines which are on your local network. The
# following example restricts access to two C class networks and
# the "loopback" interface. For more examples of the syntax see
# the smb.conf man page

# it is non-standard. Currently supported print systems include:
# bsd, cups, sysv, plp, lprng, aix, hpux, qnx

# Uncomment this if you want a guest account, you must add this to /etc/passwd
# otherwise the user "nobody" is used

# Use password server option only with security = server

; local master = no
# OS Level determines the precedence of this server in master browser
# elections. The default value should be reasonable

# Domain Master specifies Samba to be the Domain Master Browser. This
# allows Samba to collate browse lists between subnets. Don't use this
# if you already have a Windows NT domain controller doing this job
; domain master = yes
# Preferred Master causes Samba to force a local browser election on startup
# and gives it a slightly higher chance of winning the election

# Windows95 workstations.
