Komputery widzą serwer samby ale zasoby nie są dostępne

Post autor: goska_23 »

Witam.

Mam od pewnego czasu problem z jednym z dwóch serwerów z Debianem 6.0.4. Na jednym z nich próbowałam jakiś czas temu zainstalować serwer poczty - serwera tego w końcu nie zainstalowałam i odłożyłam ten temat na "potem".

Niestety, po tej próbie instalacji zepsuł mi się serwer samby na tym właśnie Debianie, na którym próbowałam zainstalować serwer poczty.

Komputery z Windowsem widzą ten serwer samby jako komputer "db" ale nie można wejść do żadnego z udostępnianych zasobów, na tym serwerze samby.

Wyświetla się komunikat:

Kod: Zaznacz cały

  \\Db nie jest dostępny. Możesz nie mieć uprawnień do używania tego zasobu sieciowego. Skontaktuj się z administratorem tego serwera, aby uzyskać uprawnienia dostępu.
Wydaje mi się, że plik konfiguracyjny samby na tym serwerze mam skonfigurowany poprawnie bo nic nie zmieniałam w trakcie próby instalacji serwera pocztowego, ponadto mam drugi komputer również z Debianem 6.04, na którym też jest samba, plik konfiguracyjny jest taki sam i do zasobów samby można się podłączyć.

Może ktoś ma pomysł gdzie można jeszcze coś sprawdzić w ustawieniach, gdzie szukać przyczyny tego problemu?

Dodane:
Plik samby smb.conf jest następujacy:

#======================= Global Settings =======================

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
   workgroup = CC
  
# server string is the equivalent of the NT Description field
   server string = %h server
 
  # Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
#   wins support = no

# 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

# This will prevent nmbd to search for NetBIOS names through DNS.
   dns proxy = no

# What naming service and in what order should we use to resolve host names
# to IP addresses
;   name resolve order = lmhosts host wins bcast



#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth1

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
;   bind interfaces only = yes



#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
   max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
#   syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
   syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
   panic action = /usr/share/samba/panic-action %d


####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
security = share
default service = global
available = no

# You may wish to use password encryption.  See the section on
# 'encrypt passwords' in the smb.conf(5) manpage before enabling.
   encrypt passwords = true

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.  
   passdb backend = tdbsam

   obey pam restrictions = yes

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
   unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
   passwd program = /usr/bin/passwd %u
   passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
   pam password change = yes

########## Domains ###########

# Is this machine able to authenticate users. Both PDC and BDC
# must have this setting enabled. If you are the BDC you must
# change the 'domain master' setting to no
#
;   domain logons = yes
#
# The following setting only takes effect if 'domain logons' is set
# It specifies the location of the user's profile directory
# from the client point of view)
# The following required a [profiles] share to be setup on the
# samba server (see below)
;   logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
#   logon path = \\%N\%U\profile

# The following setting only takes effect if 'domain logons' is set
# It specifies the location of a user's home directory (from the client
# point of view)
;   logon drive = H:
#   logon home = \\%N\%U

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
;   logon script = logon.cmd

# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe.  The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

# This allows machine accounts to be created on the domain controller via the 
# SAMR RPC pipe.  
# The following assumes a "machines" group exists on the system
; add machine script  = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

# This allows Unix groups to be created on the domain controller via the SAMR
# RPC pipe.  
; add group script = /usr/sbin/addgroup --force-badname %g

########## Printing ##########

# If you want to automatically load your printer list rather
# than setting them up individually then you'll need this
#   load printers = yes

# lpr(ng) printing. You may wish to override the location of the
# printcap file
;   printing = bsd
;   printcap name = /etc/printcap

# CUPS printing.  See also the cupsaddsmb(8) manpage in the
# cupsys-client package.
;   printing = cups

W czasie próby instalacji serwera poczty zmieniałam w plikach debiana grupę roboczą CC na domenę mojadomena1.pl, ale potem przywróciłam grupę roboczą CC - może tutaj gdzieś jest źródło problemu?

Sprawdź uprawnienia plików udziałów to po pierwsze, po drugie wklej log samby z twojej konfiguracji wynika że jest w /var/log/samba/log.smbd.

Po trzecie, nie wiem, czy nie powinnaś używać:

Kod: Zaznacz cały

seciurity = user
zamiast:

share
jeżeli w dostępnie do jednego z udziałów używasz:

i prawa dostępu:
Po trzecie:

Jak możesz to zamontuj, któryś z zasobów (najlepiej ten ogólnodostępny i ten chroniony hasłem) w Windowsie za pomocą mapowania dysków sieciowych i wtedy wklej log samby dla tej maszyny.

Kod: Zaznacz cały

 
# This tells Samba to use a separate log file for each machine# that connects
   log file = /var/log/samba/log.%m
To miejsce w pliku konfiguracyjnym wskazuje, że powinien być plik logu o nazwie log.'nazwa NetBIOS komputera' dla celów debugowania.

Ten serwer samby też nie cały czas jest widoczny w grupie CC z komputerów z Windowsem - po restarcie tego Debiana go widzę, ale jak coś ruszę na sieci np. zmienię grupę roboczą komputerowi z Windowsem to już go nie widzi. Nie wyszukuje też tego serwera "Db" z komputera z Windowsem - znajduje zamiast niego drugiego Debiana o nazwie "DB2". Na pingi odpowiada ale nie wyszukuje po IP: 192.168.1.100.

Ten drugi Debian, na którym samba działa ma IP:192.168.1.106.

Dodane:
Nie mogę mapować, nie pokazuje zasobów przy próbie mapowania. Jest plik logu log.db ale jest pusty.

W konfiguracji masz jeszcze coś takiego w sekcji Authentication: 'available = no', według dokumentacji:

Kod: Zaznacz cały

This parameter lets you "turn off" a service. If available = no, then ALL attempts to connect to the service will fail. Such failures are logged.
Default: available = yes
Usuń ten wpis albo zmień na 'yes', nigdy tego nie używałem tak samo z: 'default serivce = global', też bym usunął.

To niestety nie pomaga, zmiana tych ustawień. Jest to raczej jakiś problem z ustawieniami sieciowymi - bo chociaż na ping odpowiada i po IP i po nazwie to jednak ani po IP ani po nazwie nie wyszukuje tego komputera z Debianem na Windowsie. Komputer z Debianem jest widoczny w grupie roboczej CC z innymi komputerami z Windowsem dopóki czegoś nie "ruszę" w sieci - jak coś ruszę - to trzeba komputer z Debianem zrestartować aby się pokazywał ponownie w grupie roboczej.

I jeszcze jedno, przeładowujesz serwer Samby po każdej zmianie w pliku konfiguracyjnym, jako root?

lub:
