Доброго времени суток! Есть сервер, на котором была настроена Samba 3. Всё было хорошо, было расшарено 3 каталога. И тут  чёрт меня дёрнул обновить пакеты Samba до версии 4. Всё хорошо обновилось, но теперь директории не видны. Также не возможно зайти по адресу \\ххх.ххх.ххх.ххх.

Компьютеров в сети очень много и smbstatus выдаёт что вроде как подключения идут. Тогда экспериментальным путём я выяснил что если постоянно пытаться зайти на расшаренные директории (подключенные как сетевые диски), то иногда это получается, но затем тут же происходит обрыв. Как будто есть какое-то ограничение на количество одновременных соединений.

Но конфиги остались прежними от 3 версии.

Как быть?

Подключал я  samba 4  к windows server 2008
Уже отчеты пишу на Магее но сетевые принтера не могу подключить.
Не совсем то, но может пригодится.

Лучше выкладывать весь  конфиг file:///etc/samba/smb.conf
Мой smb.conf скачал где то. Попробовал все получилось.
И делал все штатно для Магеи  -   - https://forum.mageia.org.ru/viewtopic.p … 260#p27260
А так можно сказать, что общие папки даже не описаны в конфиге

# This is the main Samba configuration file. You should read the

# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# 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.

# 1. Server Naming Options:
# workgroup = NT-Domain-Name or Workgroup-Name

# netbios name is the name you will see in "Network Neighbourhood",
# but defaults to your hostname
#  netbios name = <name_of_this_server>

# server string is the equivalent of the NT Description field

# Message command is run by samba when a "popup" message is sent to it.
# The example below is for use with LinPopUp:
; message command = /usr/bin/linpopup "%f" "%m" %s; rm %s

# 2. Printing Options:
# Required to load all CUPS printers

# printcap cache time, so samba will automatically load new cups printers

# It should not be necessary to spell out the print system type unless
# yours is non-standard. Currently supported print systems include:
# bsd, sysv, plp, lprng, aix, hpux, qnx, cups

# Samba 2.2 supports the Windows NT-style point-and-print feature. To
# use this, you need to be able to upload print drivers to the samba
# server. The printer admins (or root) may install drivers onto samba.
# Note that this feature uses the print$ share, so you will need to
# enable it below.
# Printer admins are now defined by granting the SePrintOperatorPrivilege, ie:
# run: net rpc rights grant 'DOMAIN\Printer Operators' SePrintOperatorPrivilege

# 3. Logging Options:
# this tells Samba to use a separate log file for each machine
# that connects

# Put a capping on the size of the log files (in Kb).

# Set the log (verbosity) level (0 <= log level <= 10)

# 4. Security and Domain Membership Options:
# 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. Do not enable this if (tcp/ip) name resolution does
# not work for all the hosts in your network.
# hosts allow = 10.47.17.0/255.255.255.0

# Uncomment this if you want a guest account, you must add this to /etc/passwd
# otherwise the user "nobody" is used
#  guest account = pcguest
# Allow users to map to guest:

# Security mode. Most people will want user level security. See
# security_level.txt for details.
# Use password server option only with security = server or security = domain
# When using security = domain, you should use password server = *
#   password server = <NT-Server-Name>
#   password server = *

# Password Level allows matching of _n_ characters of the password for
# all combinations of upper and lower case.
#  password level = 8
#  username level = 8

# You may wish to use password encryption. Please read
# ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba documentation.
# Do not enable this option unless you have read those documents
# Encrypted passwords are required for any use of samba in a Windows NT domain
# The smbpasswd file is only required by a server doing authentication, thus
# members of a domain do not need one.

# The following are needed to allow password changing from Windows to
# also update the Linux system password.
# NOTE: Use these with 'encrypt passwords' and 'smb passwd file' above.
# NOTE2: You do NOT need these to allow workstations to change only
#        the encrypted SMB passwords. They allow the Unix password
#        to be kept in sync with the SMB password.
;  unix password sync = Yes
# You either need to setup a passwd program and passwd chat, or
# enable pam password change
;  pam password change = yes
#  passwd program = /usr/bin/passwd '%u'
;  passwd chat = *New*UNIX*password* %n\n *Re*ype*new*UNIX*password* %n\n \
;*passwd:*all*authentication*tokens*updated*successfully*

# Unix users can map to different SMB User names
;  username map = /etc/samba/smbusers

# Using the following line enables you to customise your configuration
# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting
#   include = /etc/samba/smb.conf.%m

# Options for using winbind. Winbind allows you to do all account and
# authentication from a Windows or samba domain controller, creating
# accounts on the fly, and maintaining a mapping of Windows RIDs to unix uid's
# and gid's. winbind uid and winbind gid are the only required parameters.
#
# winbind uid is the range of uid's winbind can use when mapping RIDs to uid's
#  idmap uid = 10000-20000
#
# winbind gid is the range of uid's winbind can use when mapping RIDs to gid's
#  idmap gid = 10000-20000
#
# winbind separator is the character a user must use between their domain
# name and username, defaults to "\"
#  winbind separator = +
#
# winbind use default domain allows you to have winbind return usernames
# in the form user instead of DOMAIN+user for the domain listed in the
# workgroup parameter.
#  winbind use default domain = yes
#
# template homedir determines the home directory for winbind users, with
# %D expanding to their domain name and %U expanding to their username:
#  template homedir = /home/%D/%U

# When using winbind, you may want to have samba create home directories
# on the fly for authenticated users. Ensure that /etc/pam.d/samba is
# using 'service=system-auth-winbind' in pam_stack modules, and then
# enable obedience of pam restrictions below:
#  obey pam restrictions = yes

#
# template shell determines the shell users authenticated by winbind get
#  template shell = /bin/bash

# 5. Browser Control and Networking Options:
# Configure Samba to use multiple interfaces
# If you have multiple network interfaces then you must list them
# here. See the man page for details.
#   interfaces = 192.168.12.2/24 192.168.13.2/24

# Configure remote browse list synchronisation here
#  request announcement to, or browse list sync from:
#       a specific host or from / to a whole subnet (see below)
#   remote browse sync = 192.168.3.25 192.168.5.255
# Cause this host to announce itself to local subnets here
#   remote announce = 192.168.1.255 192.168.2.44

# set local master to no if you don't want Samba to become a master
# browser on your network. Otherwise the normal election rules apply
#   local master = no

# OS Level determines the precedence of this server in master browser
# elections. The default value should be reasonable
#   os level = 33

# 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
#   preferred master = yes

# 6. Domain Control Options:
# Enable this if you want Samba to be a domain logon server for
# Windows95 workstations or Primary Domain Controller for WinNT and Win2k
#   domain logons = yes

# if you enable domain logons then you may want a per-machine or
# per user logon script
# run a specific logon batch file per workstation (machine)
#   logon script = %m.bat
# run a specific logon batch file per username
#   logon script = %u.bat

# Where to store roaming profiles for WinNT and Win2k
#        %L substitutes for this servers netbios name, %u is username
#        You must uncomment the [Profiles] share below
#   logon path = \\%L\Profiles\%u

# Where to store roaming profiles for Win9x. Be careful with this as it also
# impacts where Win2k finds it's /HOME share
# logon home = \\%L\%u\.profile


# The add user script is used by a domain member to add local user accounts
# that have been authenticated by the domain controller, or when adding
# users via the Windows NT Tools (ie User Manager for Domains).

# Scripts for file (passwd, smbpasswd) backend:
# add user script = /usr/sbin/useradd -s /bin/false '%u'
# delete user script = /usr/sbin/userdel '%s'
# add user to group script = /usr/bin/gpasswd -a '%u' '%g'
# delete user from group script = /usr/bin/gpasswd -d '%u' '%g'
# set primary group script = /usr/sbin/usermod -g '%g' '%u'
# add group script = /usr/sbin/groupadd %g && getent group '%g'|awk -F: '{print $3}'
# delete group script = /usr/sbin/groupdel '%g'

# Scripts for LDAP backend (assumes nss_ldap is in use on the domain controller,
# and needs configuration in smbldap_conf.pm
# add user script = /usr/sbin/smbldap-useradd -m '%u'
# delete user script = /usr/sbin/smbldap-userdel '%u'
# add user to group script = /usr/sbin/smbldap-groupmod -m '%u' '%g'
# delete user from group script = /usr/sbin/smbldap-groupmod -x '%u' '%g'
# set primary group script = /usr/sbin/smbldap-usermod -g '%g' '%u'
# add group script = /usr/sbin/smbldap-groupadd '%g' && /usr/sbin/smbldap-groupshow %g|awk '/^gidNumber:/ {print $2}'
# delete group script = /usr/sbin/smbldap-groupdel '%g'


# The add machine script is use by a samba server configured as a domain
# controller to add local machine accounts when adding machines to the domain.
# The script must work from the command line when replacing the macros,
# or the operation will fail. Check that groups exist if forcing a group.
# Script for domain controller for adding machines:
# add machine script = /usr/sbin/useradd -d /dev/null -g machines -c 'Machine Account' -s /bin/false -M '%u'
# Script for domain controller with LDAP backend for adding machines (please
# configure in /etc/samba/smbldap_conf.pm first):
# add machine script = /usr/sbin/smbldap-useradd -w -d /dev/null -c 'Machine Account' -s /bin/false '%u'

# Domain groups:
# Domain groups are now configured by using the 'net groupmap' tool

# Enable priveleges, ie allowing members of Domain Admins to join machines
# to the domain
# enable privileges = yes

# Samba Password Database configuration:
# Samba now has runtime-configurable password database backends. Multiple
# passdb backends may be used, but users will only be added to the first one
# Default:
# passdb backend = tdbsam
# TDB backen with fallback to smbpasswd and guest
# passdb backend = tdbsam smbpasswd guest
# LDAP with fallback to smbpasswd guest
# Enable SSL by using an ldaps url, or enable tls with 'ldap ssl' below.
# passdb backend = ldapsam:ldaps://ldap.mydomain.com smbpasswd guest
# Use the samba2 LDAP schema:
# passdb backend = ldapsam_compat:ldaps://ldap.mydomain.com smbpasswd guest

# Idmap settings (set idmap uid and idmap gid above):
# Idmap backend to use:
# idmap backend = ldap:ldap://ldap.mydomain.com

# LDAP configuration for Domain Controlling:
# The account (dn) that samba uses to access the LDAP server
# This account needs to have write access to the LDAP tree
# You will need to give samba the password for this dn, by
# running 'smbpasswd -w mypassword'
# ldap admin dn = cn=root,dc=mydomain,dc=com
# ldap ssl = start_tls
# start_tls should run on 389, but samba defaults incorrectly to 636
# ldap port = 389
# ldap suffix = dc=mydomain,dc=com
# Seperate suffixes are available for machines, users, groups, and idmap, if
# ldap suffix appears first, it is appended to the specific suffix.
# Example for a unix-ish directory layout:
# ldap machine suffix = ou=Hosts
# ldap user suffix = ou=People
# ldap group suffix = ou=Group
# ldap idmap suffix = ou=Idmap
# Example for AD-ish layout:
# ldap machine suffix = cn=Computers
# ldap user suffix = cn=Users
# ldap group suffix = cn=Groups
# ldap idmap suffix = cn=Idmap


# 7. Name Resolution Options:
# All NetBIOS names must be resolved to IP Addresses
# 'Name Resolve Order' allows the named resolution mechanism to be specified
# the default order is "host lmhosts wins bcast". "host" means use the unix
# system gethostbyname() function call that will use either /etc/hosts OR
# DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf
# and the /etc/resolv.conf file. "host" therefore is system configuration
# dependant. This parameter is most often of use to prevent DNS lookups
# in order to resolve NetBIOS names to IP Addresses. Use with care!
# The example below excludes use of name resolution for machines that are NOT
# on the local network segment
# - OR - are not deliberately to be known via lmhosts or via WINS.
# name resolve order = wins lmhosts bcast

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server
#   wins support = yes

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
#       Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
#   wins server = w.x.y.z

# WINS Proxy - Tells Samba to answer name resolution queries on
# behalf of a non WINS capable client, for this to work there must be
# at least one  WINS Server on the network. The default is NO.
#   wins proxy = yes

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups. The built-in default for versions 1.9.17 is yes,
# this has been changed in version 1.9.18 to no.

# 8. File Naming Options:
# Case Preservation can be handy - system default is _no_
# NOTE: These can be set on a per share basis
#  preserve case = no
#  short preserve case = no
# Default case is normally upper case for all DOS files
#  default case = lower
# Be very careful with case sensitivity - it can break things!
#  case sensitive = no

# Enabling internationalization:
# you can match a Windows code page with a UNIX character set.
# Windows: 437 (US), 737 (GREEK), 850 (Latin1 - Western European),
# 852 (Eastern Eu.), 861 (Icelandic), 932 (Cyrillic - Russian),
# 936 (Japanese - Shift-JIS), 936 (Simpl. Chinese), 949 (Korean Hangul),
# 950 (Trad. Chin.).
# UNIX: ISO8859-1 (Western European), ISO8859-2 (Eastern Eu.),
# ISO8859-5 (Russian Cyrillic), KOI8-R (Alt-Russ. Cyril.)
# This is an example for french users:
#   dos charset = 850
#   unix charset = ISO8859-1

Отключите файрвол, дайте моду 777 на папки /home/meteo/MeteoDisplay и /home/meteo/telex + сделайте service smb restart ; service nmb restart Если не попрёт, смотрите ошибки в /var/log/samba/log.имя_компа и др.

Не могу понять, какой смысл править наугад конфиги, если не понятна суть проблемы. Поисковик по вашим ошибкам вот выдает  https://bugzilla.redhat.com/show_bug.cgi?id=400581 Проверьте, не ваш ли случай.

У меня всё работает... Даже не знаю, что искать, сорри... Все папки, как на ладони. Можно по-паролю, можно без. Ошибок нет. Давайте согласуем, что мы всё-таки ищем, что имеем и что хотим... wink

Ваш конфиг можно "урезать"...

Клиенты какие к серверу подключаются? Если виндовые, нужно принудительно пробовать сбросить существующие подключения:
net use * /delete /yes

Сделать рестарт samba (smb и nmb) и пробовать зайти снова...

Клиенты виндовые. Пробовал и сброс и рестарт самбы и перезагрузку сервера.

Ищу, от чего оттолкнуться. Если он не заходит даже по ip-шнику, при этом порты 137-139/445 на самбе слушаются, с компа пользователя идёт ping ip samba_сервер и коннект telnet ip-samba-сервер 445 .. 139.. + система обновлялась целиком, а не только самба - тогда мыслей больше нет. roll

Давным-давно ставил какой-то свежий выпуск samba... Были проблемы с видимостью из-за того, что стояло browseable = Yes. Исправил на browseable = yes и всё пошло. Но это был единичный случай, следующие выпуски хавали всё. Не думаю, что и здесь те же грабли. Попробуйте на всякий случай...

Проблема в том, что обновлялась только samba

Исправил. После запуска самбы могу зайти и увидеть расшаренные папки. Но зайти в них не могу, пишет "Нет доступа к .... Вазможно, у вас нет прав на использование этого сетевого ресурса.

У samba3 и 4 данные идентификации (базы с именами/паролями) находятся в разных местах. У вас в конфиге старый формат. Чтобы samba4 читала /etc/samba/smbpasswd нужно добавить в [global] passdb backend = smbpasswd Посмотрите ещё раз мой конфиг выше, может пригодится.

Сделал. По крайней мере сейчас шары отображаются стабильно. Кроме того, раньше запуск samba приводил к большой загрузке ЦП, а сейчас всё в порядке. Но в шары всё равно не пускает. Иногда пустит и тут же вылетает.

И логи стали более сдержанные:

Создайте новую шару для эксперимента с минимальными опциями для примера, как она себя поведёт? Как сетевой диск временно не используйте, достучитесь до папки сначала, а там видно будет.

19 (2018-11-18 10:31:39 отредактировано alex_q_2000)

Мне так же не понятно, каким образом Вы используете ограничения по юзерам (security = user) без наличия валидных юзеров на шары. Отключите пароль вообще (map to guest = Bad User) и добейтесь устойчивой работы с новой шарой для начала.

p.s. Настройка файл-сервера Samba 4 с авторизацией по логину/паролю

alex_q_2000⇓ пишет:

Попробовал - не помогло

21

Проверил конфиг командой testparm, исправил все ошибки. Но ситуация та же.

22

А вопрос. Для самбы нужно создавать специальных пользователей?

23

Я уже настроил отдельный сервер на Mageia 6.1. Поставил туда samba, там всё работает. Скопировал конфиг - всё равно не работает.

24

neket89⇓ пишет:

Если нужен доступ к папкам по паролю, то да. Юзеры добавляются в саму систему (adduser user) и для samba (smbpasswd -a user; smbpasswd -e user). Данные падают в /etc/samba/smbpasswd, на который ссылается соответствующая строчка у Вас в конфиге. Что-то мне подсказывает, что Вы не используете идентификацию по паролю. Вы просто используете папки Display на чтение для всех и Telex для чтения/записи... Проблемы с подключением могут быть на клиентах Windows XP. В этом случае рекомендуют добавлять в [global] ntlm auth = yes Клиенты не XP случайно?

Скопировал конфиг откуда и куда...

alex_q_2000⇓ пишет:

Клиенты всякие: и ХР и 7 и 10.

alex_q_2000⇓ пишет:

Установил и настроил Mageia 6.1 на новый компьютер. На нём настроил Samba 4. На новом компьютере всё работает. Именование пользователей, рабочей группы, права на каталоги сделал идентично серверу, на котором сейчас Samba не работает. В итоге на новом компьютере всё работает, каталоги доступны. Тогда я с нового компьютера полностью скопировал конфиг samba и это не помогло.
