Servidor Samba[RESOLVIDO]

[magubuntu]

Hoje, ao chegar na empresa, fui tentar acessar as unidades de compartilhamento do servidor samba, e pra minha surpresa nao consegui, não sei o que aconteceu. o que sei dizer é que a máquina foi desligada no sabado, pois o pessoal da manutenção iria mexer a parte eletrica e as maquinas precisavam ser desligadas. Não consgigo acessar as unidades pela rede. Quando acesso pelo windows dá a seguinte mensagem: "o caminho da rede nao foi encontrado".

Por favor peço ajuda,

Fernando

Vamos olhar todos os detalhes primeiro:

1- Confira a configuração de rede (IP, DNS...) da máquina

2- Confira o nome da máquina

3- Usa Grupo ou Domínio?

4- Dẽ uma olhada no aquivo de configuração (smb.conf) e poste ele aqui se possível.

[magubuntu]

caro sot-legend, já verifiquei a configuração de rede, tá ok; o nome da maquina nao alterou; usa dominio; vou postar pra vc a cofiguração do smb.conf:

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# 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 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 commentary 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]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
   workgroup = labrecife

# server string is the equivalent of the NT Description field
   server string = %h server (Samba, Ubuntu)

# 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.v

# 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 eth0

# 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 = true



#### 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 = user

# 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 = no

   guest account = unirecife, universo
#   invalid users = root

# 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

# This option controls how nsuccessful authentication attempts are mapped
# to anonymous connections
map to guest = bad user

########## 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
;   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

########## 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( manpage in the
# cupsys-client package.

Confirme que os serviços do Samba (smbd e nmbd) estão ativos.

smbstatus

sudo service smbd status
sudo service nmbd status

Se não estiverem, vc terá que configurar o sistema pra carregá-los automaticamente:

sudo update-rc.d smbd defaults
sudo update-rc.d nmbd defaults

[sot-legend]

Concordo perfeitamente com ele...

Confirme que os serviços do Samba (smbd e nmbd) estão ativos.

smbstatus

sudo service smbd status
sudo service nmbd status

Se não estiverem, vc terá que configurar o sistema pra carregá-los automaticamente:

sudo update-rc.d smbd defaults
sudo update-rc.d nmbd defaults

mas se preferir use o Likewise pra se conectar ao domínio, e depois de um restart no samba

[magubuntu]

Eu dei o comando top, mas nao aparece o serviço do samba na lista de processos. Quando eu dou os comandos: sudo service smbd status e sudo service nmbd status recebo a mensagem: command not found

[sot-legend]

tente assim:

Código Selecionar Expandir


/etc/init.d/smbd force-reload


[magubuntu]

dentro do diretório ini.d não tem o smbd, só tem o samba. Eu já dei o comando /etc/init.d/samba restart, mas aparece a mensagem:  * Stopping Samba daemons                                                                                                    start-stop-daemon: warning: failed to kill 4895: No such process
                                                                                                                      [ OK ]
* Starting Samba daemons                                                                                             [ OK ]

[sot-legend]

Cara, teu samba ta com erro, eu sugiro você a voltar a um backup estável (caso tenha) ou reinstalar e fazer tudo de novo.

[magubuntu]

sot-legend, devo reinstar todo sistema do zero ou só o samba? onde vc verificou o erro?

Grato

[sot-legend]

o erro ta aqui:

* Stopping Samba daemons     start-stop-daemon: warning: failed to kill 4895: No such process

Ele não encontra o processo pra dar o restart, vamo tentar mata-lo pra iniciar a parte...

Código Selecionar Expandir


ps ax | grep samba


quando ele te voltar o número do processo, execute:

Código Selecionar Expandir


kill -15 (numero do processo)


após feito isso rode um:

Código Selecionar Expandir


/etc/init.d/samba start


[zekkerj]

sot-legend, devo reinstar todo sistema do zero ou só o samba? onde vc verificou o erro?

Grato

Pode tentar reinstalar só o Samba primeiro...

sudo apt-get install --reinstall samba samba-common

[magubuntu]

Amigos, consegui. Eu tinha um backup do samba, então voltei a esse backup e funcionou novamente. ufa!!!! Mas o que deve ter causado isso? Agradeço pela boa vontade de vcs, muito grato mesmo.

Com certeza um poltergeist =D

[magubuntu]

Aproveitando, como durante esse tempo ficamos sem acessar os arquivos que estavam compartilhados, eu queria saber de vcs se tem como colocar um segundo hd nessa máquina e um script fazendo backup altomático pra esse segundo hd, porque dessa forma, se fosse necessário refazer a máquina eu tirava esse segundo hd e deixava mapqado em outro pc enquando preparava o server novamente. vcs tem alguma sugestão nessa linha?

Grato
